49−
50−This change is achieved by the introduction of a CaptureHint type, which is passed as an extra argument to the CaptureRouter and CaptureAllRouter constructors for the Router' type.
51−CaptureHint values are then used in routerLayout, to display the name and type of captured values, instead of just `<capture>` previously.
52−
53−N.B.:
54−Because the choice smart constructor for routers can aggregate Capture combinators with different capture hints, the Capture*Router constructors actually take a list of CaptureHint, instead of a single one.
55−
56−This PR also introduces Spec tests for the routerLayout function.
57−
58−Warning:
59−This change is potentially breaking, because it adds the constraint `Typeable a` to all types that are to be captured. Because all types are typeable since GHC 7.10, this is not as bad as it sounds ; it only break expressions where `a` is quantified in an expression with `Capture a`.
60−In those cases, the fix is easy: it suffices to add `Typeable a` to the left-hand side of the quantification constraint.
61−
62−For instance, the following code will no longer compile:
63−```haskell
64−type MyAPI a = Capture "foo" a :> Get '[JSON] ()
65−
66−myServer :: forall a. Server (MyAPI a)

75−
76−Indeed, `app` should be replaced with:

77−## Error formatters
78−
79−`servant-server` provides an `ErrorFormatter` type to specify how the error message will be
80−formatted. A formatter is just a function accepting three parameters:
81−
82−- `TypeRep` from `Data.Typeable`: this is a runtime representation of the type of the combinator
83− (like `Capture` or `ReqBody`) that generated the error. It can be used to display its name (with
84− `show`) or even dynamically dispatch on the combinator type. See the docs for `Data.Typeable` and
85− `Type.Reflection` modules.
86−- `Request`: full information for the request that led to the error.
87−- `String`: specific error message from the combinator.
88−
89−The formatter is expected to produce a `ServerError` which will be returned from the handler.
90−
91−Additionally, there is `NotFoundErrorFormatter`, which accepts only `Request` and can customize the
92−error in case when no route can be matched (HTTP 404).
93−
94−Let's make two formatters. First one will wrap our error in a JSON:
95−
96−```json
97−{
98− "error": "ERROR MESSAGE",
99− "combinator": "NAME OF THE COMBINATOR"
100−}
101−```
102−
103−Additionally, this formatter will examine the `Accept` header of the request and generate JSON
104−message only if client can accept it.
105−
106−```haskell
107−customFormatter :: ErrorFormatter
108−customFormatter tr req err =
109− let
110− -- aeson Value which will be sent to the client
111− value = object ["combinator" .= show tr, "error" .= err]
112− -- Accept header of the request
113− accH = getAcceptHeader req
114− in
115− -- handleAcceptH is Servant's function that checks whether the client can accept a
116− -- certain message type.
117− -- In this case we call it with "Proxy '[JSON]" argument, meaning that we want to return a JSON.
118− case handleAcceptH (Proxy :: Proxy '[JSON]) accH value of
119− -- If client can't handle JSON, we just return the body the old way
120− Nothing -> err400 { errBody = cs err }
121− -- Otherwise, we return the JSON formatted body and set the "Content-Type" header.
122− Just (ctypeH, body) -> err400
123− { errBody = body
124− , errHeaders = [("Content-Type", cs ctypeH)]
125− }

127−notFoundFormatter :: NotFoundErrorFormatter
128−notFoundFormatter req =
129− err404 { errBody = cs $ "Not found path: " <> rawPathInfo req }
130−```
131−

142−## Passing formatters to Servant
143−
144−Servant uses the Context to configure formatters. You only need to add a value of type
145−`ErrorFormatters` to your context. This is a record with the following fields:
146−
147−- `bodyParserErrorFormatter :: ErrorFormatter`
148−- `urlParseErrorFormatter :: ErrorFormatter`
149−- `headerParseErrorFormatter :: ErrorFormatter`
150−- `notFoundErrorFormatter :: NotFoundErrorFormatter`
151−
152−Default formatters are exported as `defaultErrorFormatters`, so you can use record update syntax to
153−set the only ones you need:
154−
155−```haskell
156−customFormatters :: ErrorFormatters
157−customFormatters = defaultErrorFormatters
158− { bodyParserErrorFormatter = customFormatter
159− , notFoundErrorFormatter = notFoundFormatter
160− }
161−```
162−
163−And at last, use `serveWithContext` to run your server as usual:
164−
165−```haskell
166−app :: Application
167−app = serveWithContext testApi (customFormatters :. EmptyContext) server
168−
169−main :: IO ()
170−main = run 8000 app
171−```
172−
173−Now if we try to request something with a wrong body, we will get a nice error:
174−
175−```

187−There is the [issue from
188−2017](https://github.com/haskell-servant/servant/issues/841) that was
189−resolved by the introduction of `UVerb`, with a long discussion on
190−alternative designs.

192−[servant-checked-exceptions](https://hackage.haskell.org/package/servant-checked-exceptions)
193−is a good solution to the problem, but it restricts the user to JSON
194−and a very specific envelop encoding for the union type, which is
195−often not acceptable. (One good reason for this design choice is that
196−it makes writing clients easier, where you need to get to the union
197−type from one representative, and you don't want to run several
198−parsers in the hope that the ones that should will always error out so
199−you can try until the right one returns a value.)
200−
201−[servant-exceptions](https://github.com/ch1bo/servant-exceptions) is
202−another shot at the problem. It is inspired by
203−servant-checked-exceptions, so it may be worth taking a closer look.
204−The README claims that
205−[cardano-sl](https://github.com/input-output-hk/cardano-sl) also has
206−some code for generalized error handling.

209−code from
210−[world-peace](https://hackage.haskell.org/package/world-peace), but

44−Note for Ubuntu users
45−--------
46−
47−Ubuntu's packages for `ghc`, `cabal`, and `stack` are years out of date.
48−If the instructions above fail for you,
49−try replacing the Ubuntu packages with up-to-date versions.
50−First remove the installed versions:
51−
52−.. code-block:: bash
53−
54− # remove the obsolete versions
55− $ sudo apt remove ghc haskell-stack cabal-install
56−
57−Then install fresh versions of the Haskell toolchain
58−using the `ghcup <https://www.haskell.org/ghcup/install/>`_ installer.
59−
60−As of February 2022, one easy way to do this is by running a bootstrap script:
61−
62−.. code-block:: bash
63−
64− $ curl --proto '=https' --tlsv1.2 -sSf https://get-ghcup.haskell.org | sh
65−
66−The script is interactive and will prompt you for details about what
67−you want installed and where. To install manually,
68−see `the detailed instructions <https://www.haskell.org/ghcup/install/#manual-install>`_.

238−### XSRF and the frontend
239−
240−XSRF protection works by requiring that there be a header of the same value as
241−a distinguished cookie that is set by the server on each request. What the
242−cookie and header name are can be configured (see `xsrfCookieName` and
243−`xsrfHeaderName` in `CookieSettings`), but by default they are "XSRF-TOKEN" and
244−"X-XSRF-TOKEN". This means that, if your client is a browser and you're using
245−cookies, Javascript on the client must set the header of each request by
246−reading the cookie. For jQuery, and with the default values, that might be:
247−
248−~~~ javascript
249−
250−var token = (function() {
251− r = document.cookie.match(new RegExp('XSRF-TOKEN=([^;]+)'))
252− if (r) return r[1];
253−})();
254−
255−
256−$.ajaxPrefilter(function(opts, origOpts, xhr) {
257− xhr.setRequestHeader('X-XSRF-TOKEN', token);
258− }
259−
260−~~~
261−
262−I *believe* nothing at all needs to be done if you're using Angular's `$http`
263−directive, but I haven't tested this.
264−
265−XSRF protection can be disabled just for `GET` requests by setting
266−`xsrfExcludeGet = False`. You might want this if you're relying on the browser
267−to navigate between pages that require cookie authentication.
268−
269−XSRF protection can be completely disabled by setting `cookieXsrfSetting =
270−Nothing` in `CookieSettings`. This is not recommended! If your cookie
271−authenticated web application runs any javascript, it's recommended to send the
272−XSRF header. However, if your web application runs no javascript, disabling
273−XSRF entirely may be required.

23−- Drop support for GHC < 8.6.

25−- Support Aeson 2 ([#1475](https://github.com/haskell-servant/servant/pull/1475)),
26− which fixes a [DOS vulnerability](https://github.com/haskell/aeson/issues/864)
27− related to hash collisions.
28−- Add `NamedRoutes` combinator, making support for records first-class in Servant
29− ([#1388](https://github.com/haskell-servant/servant/pull/1388)).

82−
83− The `NoContent` API endpoints should now use `NoContentVerb` combinator.

106−
107− Some APIs need query parameters rewriting, e.g. in order to support
108− for multiple casing (camel, snake, etc) or something to that effect.
109−
110− This could be easily achieved by using WAI Middleware and modifying
111− request's `Query`. But QueryParam, QueryParams and QueryFlag use
112− `rawQueryString`. By using `queryString` rather then `rawQueryString`
113− we can enable such rewritings.
114−
115−- *servant* *servant-server* Make packages `build-type: Simple` [#1263](https://github.com/haskell-servant/servant/pull/1263)
116−
117− We used `build-type: Custom`, but it's problematic e.g.
118− for cross-compiling. The benefit is small, as the doctests
119− can be run other ways too (though not so conveniently).

10−
11−### Motivation
12−
13−Swagger is a project used to describe and document RESTful APIs.
14−Unlike Servant it is language-agnostic and thus is quite popular among developers
15−in different languages. It also exists for a longer time and has more tools to work with.
16−
17−This package provides means to generate Swagger specification for a Servant API
18−and also to partially test whether API conforms with its specification.
19−
20−Generated Swagger specification then can be used for many things such as
21−- displaying interactive documentation using [Swagger UI](http://swagger.io/swagger-ui/);
22−- generating clients and servers in many languages using [Swagger Codegen](http://swagger.io/swagger-codegen/);
23−- and [many others](http://swagger.io/open-source-integrations/).
24−
25−### Usage
26−
27−Please refer to [haddock documentation](http://hackage.haskell.org/package/servant/servant-swagger).
28−
29−Some examples can be found in [`example/` directory](/example).
30−
31−### Try it out
32−
33−All generated swagger specifications can be interactively viewed on [Swagger Editor](http://editor.swagger.io/).
34−
35−Ready-to-use specification can be served as JSON and interactive API documentation
36−can be displayed using [Swagger UI](https://github.com/swagger-api/swagger-ui).
37−
38−Many Swagger tools, including server and client code generation for many languages, can be found on
39−[Swagger's Tools and Integrations page](http://swagger.io/open-source-integrations/).
40−
41−### Contributing
42−
43−We are happy to receive bug reports, fixes, documentation enhancements, and other improvements.

4−synopsis: Generate a Swagger/OpenAPI/OAS 2.0 specification for your servant API.
5−description:
6− Swagger is a project used to describe and document RESTful APIs. The core of the
7− project is the [OpenAPI Specification (OAS)](https://swagger.io/docs/specification/about/).
8− This library implements v2.0 of the spec. Unlike Servant it is language-agnostic and thus is
9− quite popular among developers in different languages. It has also existed for a longer time
10− and has more helpful tooling.
11− .
12− This package provides means to generate a Swagger/OAS specification for a Servant API
13− and also to partially test whether an API conforms with its specification.
14− .
15− Generated Swagger specification then can be used for many things such as
16− .
17− * displaying interactive documentation using [Swagger UI](http://swagger.io/swagger-ui/);
18− .
19− * generating clients and servers in many languages using [Swagger Codegen](http://swagger.io/swagger-codegen/);
20− .
21− * and [many others](http://swagger.io/open-source-integrations/).

81−-- $howto
82−--
83−-- This section explains how to use this library to generate Swagger specification,
84−-- modify it and run automatic tests for a servant API.
85−--
86−-- For the purposes of this section we will use this servant API:
87−--
88−-- >>> data User = User { name :: String, age :: Int } deriving (Show, Generic, Typeable)
89−-- >>> newtype UserId = UserId Integer deriving (Show, Generic, Typeable, ToJSON)
90−-- >>> instance ToJSON User
91−-- >>> instance ToSchema User
92−-- >>> instance ToSchema UserId
93−-- >>> instance ToParamSchema UserId
94−-- >>> type GetUsers = Get '[JSON] [User]
95−-- >>> type GetUser = Capture "user_id" UserId :> Get '[JSON] User
96−-- >>> type PostUser = ReqBody '[JSON] User :> Post '[JSON] UserId
97−-- >>> type UserAPI = GetUsers :<|> GetUser :<|> PostUser
98−--
99−-- Here we define a user API with three endpoints. @GetUsers@ endpoint returns a list of all users.
100−-- @GetUser@ returns a user given his\/her ID. @PostUser@ creates a new user and returns his\/her ID.
101−
102−-- $generate
103−-- In order to generate @'Swagger'@ specification for a servant API, just use @'toSwagger'@:
104−--
105−-- >>> BSL8.putStrLn . orderedKeys $ toSwagger (Proxy :: Proxy UserAPI)
106−-- {"definitions":{"User":{"properties":{"age":{"maximum":9223372036854775807,"minimum":-9223372036854775808,"type":"integer"},"name":{"type":"string"}},"required":["name","age"],"type":"object"},"UserId":{"type":"integer"}},"info":{"title":"","version":""},"paths":{"/":{"get":{"produces":["application/json;charset=utf-8"],"responses":{"200":{"description":"","schema":{"items":{"$ref":"#/definitions/User"},"type":"array"}}}},"post":{"consumes":["application/json;charset=utf-8"],"parameters":[{"in":"body","name":"body","required":true,"schema":{"$ref":"#/definitions/User"}}],"produces":["application/json;charset=utf-8"],"responses":{"200":{"description":"","schema":{"$ref":"#/definitions/UserId"}},"400":{"description":"Invalid `body`"}}}},"/{user_id}":{"get":{"parameters":[{"in":"path","name":"user_id","required":true,"type":"integer"}],"produces":["application/json;charset=utf-8"],"responses":{"200":{"description":"","schema":{"$ref":"#/definitions/User"}},"400":{"description":"Invalid `user_id`"}}}}},"swagger":"2.0"}
107−--
108−-- By default @'toSwagger'@ will generate specification for all API routes, parameters, headers, responses and data schemas.
109−--
110−-- For some parameters it will also add 400 responses with a description mentioning parameter name.

132−-- @'subOperations' sub api@ traverses all operations of the @api@ which are also present in @sub@.

148−
149−-- $test
150−-- Automatic generation of data schemas uses @'ToSchema'@ instances for the types
151−-- used in a servant API. But to encode/decode actual data servant uses different classes.
152−-- For instance in @UserAPI@ @User@ is always encoded/decoded using @'ToJSON'@ and @'FromJSON'@ instances.
153−--
154−-- To be sure your Haskell server/client handles data properly you need to check
155−-- that @'ToJSON'@ instance always generates values that satisfy schema produced
156−-- by @'ToSchema'@ instance.
157−--
158−-- With @'validateEveryToJSON'@ it is possible to test all those instances automatically,
159−-- without having to write down every type:
160−--
161−-- >>> instance Arbitrary User where arbitrary = User <$> arbitrary <*> arbitrary
162−-- >>> instance Arbitrary UserId where arbitrary = UserId <$> arbitrary
163−-- >>> hspec $ validateEveryToJSON (Proxy :: Proxy UserAPI)
164−-- <BLANKLINE>
165−-- [User]...
166−-- ...
167−-- User...
168−-- ...
169−-- UserId...
170−-- ...
171−-- Finished in ... seconds
172−-- 3 examples, 0 failures
173−--
174−-- Although servant is great, chances are that your API clients don't use Haskell.
175−-- In many cases @swagger.json@ serves as a specification, not a Haskell type.
176−--
177−-- In this cases it is a good idea to store generated and annotated @'Swagger'@ in a @swagger.json@ file
178−-- under a version control system (such as Git, Subversion, Mercurial, etc.).
179−--
180−-- It is also recommended to version API based on changes to the @swagger.json@ rather than changes
181−-- to the Haskell API.
182−--
183−-- See <example/test/TodoSpec.hs TodoSpec.hs> for an example of a complete test suite for a swagger specification.
184−
185−-- $serve
186−-- If you're implementing a server for an API, you might also want to serve its @'Swagger'@ specification.

13−### Significant changes
14−
15−- Drop support for GHC < 8.6.
16−- Support GHC 9.0 (GHC 9.2 should work as well, but isn't fully tested yet).
17−- Support Aeson 2 ([#1475](https://github.com/haskell-servant/servant/pull/1475)),
18− which fixes a [DOS vulnerability](https://github.com/haskell/aeson/issues/864)
19− related to hash collisions.
20−- Add `NamedRoutes` combinator, making support for records first-class in Servant
21− ([#1388](https://github.com/haskell-servant/servant/pull/1388)).
22−
23− Users can now directly mark part as an API as defined by a record, instead of
24− using `(:<|>)` to combine routes. Concretely, the anonymous:
25−
26− ```haskell
27− type API =
28− "version" :> Get '[JSON] String :<|>
29− "products" :> Get '[JSON] [Product]
30− ```
31−
32− can be replaced with the explicitly-named:
33−
34− ```haskell
35− type API = NamedRoutes NamedAPI
36− data NamedAPI mode = NamedAPI
37− { version :: mode :- "version" :> Get '[JSON] String
38− , products :: mode :- "products" :> Get '[JSON] [Product]
39− }
40− ```
41−
42− `NamedRoutes` builds upon `servant-generic`, but improves usability by freeing
43− users from the need to perform `toServant` / `fromServant` conversions
44− manually. Serving `NamedRoutes NamedAPI` is now done directly by providing a
45− record of handlers, and servant generates clients directly as records as well.
46− In particular, it makes it much more practical to work with nested hierarchies
47− of named routes.
48−
49− Two convenience functions, `(//)` and `(/:)`, have been added to make the
50− usage of named route hierarchies more pleasant:
51−
52− ```haskell
53− rootClient :: RootApi (AsClientT ClientM)
54− rootClient = client (Proxy @API)
55−
56− helloClient :: String -> ClientM String
57− helloClient name = rootClient // hello /: name
58−
59− endpointClient :: ClientM Person
60− endpointClient = rootClient // subApi /: "foobar123" // endpoint
61−
62− type Api = NamedRoutes RootApi
63−
64− data RootApi mode = RootApi
65− { subApi :: mode :- Capture "token" String :> NamedRoutes SubApi
66− , hello :: mode :- Capture "name" String :> Get '[JSON] String
67− , …
68− } deriving Generic
69−
70− data SubApi mode = SubApi
71− { endpoint :: mode :- Get '[JSON] Person
72− , …
73− } deriving Generic
74− ```
75−
76−- Add custom type errors for partially applied combinators
77− ([#1289](https://github.com/haskell-servant/servant/pull/1289),
78− [#1486](https://github.com/haskell-servant/servant/pull/1486)).
79−
80− For example, forgetting to document the expected type for a query parameter,
81− as in:
82−
83− ``` haskell
84− type API = QueryParam "param" :> Get '[JSON] NoContent
85− ```
86−
87− will raise to the following error when trying to serve the API:
88−
89− ```
90− • There is no instance for HasServer (QueryParam'
91− '[Optional, Strict] "param" :> ...)
92− QueryParam' '[Optional, Strict] "1" expects 1 more arguments
93− ```
94−
95− As a consequence of this change, unsaturated types are now forbidden before `(:>)`.
96−
97−- Add a `HeadNoContent` verb ([#1502](https://github.com/haskell-servant/servant/pull/1502)).
98−

183−

189− + :<|> PostNoContent
190− ```
191−

193−
194−- `Capture` can be `Lenient` [#1155](https://github.com/haskell-servant/servant/issues/1155) [#1156](https://github.com/haskell-servant/servant/pull/1156)
195−
196− You can specify a lenient capture as
197−
198− ```haskell
199− :<|> "capture-lenient" :> Capture' '[Lenient] "foo" Int :> GET
200− ```
201−
202− which will make the capture always succeed. Handlers will be of the
203− type `Either String CapturedType`, where `Left err` represents
204− the possible parse failure.
205−
206−- *servant-client* Added a function to create Client.Request in ClientEnv [#1213](https://github.com/haskell-servant/servant/pull/1213) [#1255](https://github.com/haskell-servant/servant/pull/1255)
207−
208− The new member `makeClientRequest` of `ClientEnv` is used to create
209− `http-client` `Request` from `servant-client-core` `Request`.
210− This functionality can be used for example to set
211− dynamic timeouts for each request.
212−
213−- *servant-server* use queryString to parse QueryParam, QueryParams and QueryFlag [#1249](https://github.com/haskell-servant/servant/pull/1249) [#1262](https://github.com/haskell-servant/servant/pull/1262)
214−
215− Some APIs need query parameters rewriting, e.g. in order to support
216− for multiple casing (camel, snake, etc) or something to that effect.
217−
218− This could be easily achieved by using WAI Middleware and modifying
219− request's `Query`. But QueryParam, QueryParams and QueryFlag use
220− `rawQueryString`. By using `queryString` rather then `rawQueryString`
221− we can enable such rewritings.
222−
223−- *servant* *servant-server* Make packages `build-type: Simple` [#1263](https://github.com/haskell-servant/servant/pull/1263)
224−
225− We used `build-type: Custom`, but it's problematic e.g.
226− for cross-compiling. The benefit is small, as the doctests
227− can be run other ways too (though not so conveniently).
228−
229−- *servant* Remove deprecated modules [1268#](https://github.com/haskell-servant/servant/pull/1268)
230−

237−
238− For `Verb`s with response `Headers`, the implementation didn't check
239− for the content-type of the response. Now it does.
240−
241−- *servant-docs* Merge documentation from duplicate routes [#1240](https://github.com/haskell-servant/servant/issues/1240) [#1241](https://github.com/haskell-servant/servant/pull/1241)
242−
243− Servant supports defining the same route multiple times with different
244− content-types and result-types, but servant-docs was only documenting
245− the first of copy of such duplicated routes. It now combines the
246− documentation from all the copies.
