# What's Hurl?

Hurl is a command line tool that runs <b>HTTP requests</b> defined in a simple <b>plain text format</b>.

It can perform requests, capture values and evaluate queries on headers and body response. Hurl is very
versatile: it can be used for both <b>fetching data</b> and <b>testing HTTP</b> sessions.

```hurl
# Get home:
GET https://example.org

HTTP/1.1 200
[Captures]
csrf_token: xpath "string(//meta[@name='_csrf_token']/@content)"

# Do login!
POST https://example.org/login?user=toto&password=1234
X-CSRF-TOKEN: {{csrf_token}}

HTTP/1.1 302
```

Chaining multiple requests is easy:

```hurl
GET https://example.org/api/health
GET https://example.org/api/step1
GET https://example.org/api/step2
GET https://example.org/api/step3
```

# Also an HTTP Test Tool

Hurl can run HTTP requests but can also be used to <b>test HTTP responses</b>.
Different types of queries and predicates are supported, from [XPath] and [JSONPath] on body response,
to assert on status code and response headers.

It is well adapted for <b>REST / JSON apis</b>

```hurl
POST https://example.org/api/tests
{
    "id": "4568",
    "evaluate": true
}

HTTP/1.1 200
[Asserts]
header "X-Frame-Options" == "SAMEORIGIN"
jsonpath "$.status" == "RUNNING"    # Check the status code
jsonpath "$.tests" count == 25      # Check the number of items
jsonpath "$.id" matches /\d{4}/     # Check the format of the id
```

<b>HTML content</b>

```hurl
GET https://example.org

HTTP/1.1 200
[Asserts]
xpath "normalize-space(//head/title)" == "Hello world!"
```

and even SOAP apis

```hurl
POST https://example.org/InStock
Content-Type: application/soap+xml; charset=utf-8
SOAPAction: "http://www.w3.org/2003/05/soap-envelope"
<?xml version="1.0" encoding="UTF-8"?>
<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:m="https://example.org">
  <soap:Header></soap:Header>
  <soap:Body>
    <m:GetStockPrice>
      <m:StockName>GOOG</m:StockName>
    </m:GetStockPrice>
  </soap:Body>
</soap:Envelope>

HTTP/1.1 200
```

Hurl can also be used to test HTTP endpoints performances:

```hurl
GET https://example.org/api/v1/pets

HTTP/1.0 200
[Asserts]
duration < 1000  # Duration in ms
```

And responses bytes content

```hurl
GET https://example.org/data.tar.gz

HTTP/1.0 200
[Asserts]
sha256 == hex,039058c6f2c0cb492c533b0a4d14ef77cc0f78abccced5287d84a1a2011cfb81;
```


# Why Hurl?

<ul class="showcase-container">
 <li><b>Text Format:</b> for both devops and developers</li>
 <li><b>Fast CLI:</b> a command line for local dev and continuous integration</li>
 <li><b>Single Binary:</b> easy to install, with no runtime required</li>
</ul>

# Powered by curl

Hurl is a lightweight binary written in [Rust]. Under the hood, Hurl HTTP engine is
powered by [libcurl], one of the most powerful and reliable file transfer library.
With its text file format, Hurl adds syntactic sugar to run and tests HTTP requests,
but it's still the [curl] that we love.

# Feedbacks

[Feedback, suggestion, bugs or improvements] are welcome!

```hurl
POST https://hurl.dev/api/feedback
{
  "name": "John Doe",
  "feedback": "Hurl is awesome !"
}
HTTP/1.1 200
```

# Samples

To run a sample, edit a file with the sample content, and run Hurl:

```shell
$ vi sample.hurl

GET https://example.org

$ hurl sample.hurl
```

By default, Hurl behaves like [curl] and outputs the last HTTP response's [entry]. To have a test
oriented output, you can use [`--test` option]:

```shell
$ hurl --test sample.hurl
```


You can check [Hurl tests suite] for more samples.

## Getting Data

A simple GET:

```hurl
GET https://example.org
```

[Doc](https://hurl.dev/docs/request.html#method)

### HTTP Headers

A simple GET with headers:

```hurl
GET https://example.org/news
User-Agent: Mozilla/5.0 
Accept: */*
Accept-Language: en-US,en;q=0.5
Accept-Encoding: gzip, deflate, br
Connection: keep-alive
```

[Doc](https://hurl.dev/docs/request.html#headers)

### Query Params

```hurl
GET https://example.org/news
[QueryStringParams]
order: newest
search: something to search
count: 100
```

Or:

```hurl
GET https://example.org/news?order=newest&search=something%20to%20search&count=100
```

[Doc](https://hurl.dev/docs/request.html#query-parameters)

### Basic Authentification

```hurl
GET https://example.org/protected
[BasicAuth]
bob: secret
```

[Doc](https://hurl.dev/docs/request.html#basic-authentification)

This is equivalent to construct the request with a [Authorization] header:

```hurl
# Authorization header value can be computed with `echo -n 'bob:secret' | base64`
GET https://example.org/protected
Authorization: Basic Ym9iOnNlY3JldA== 
```

Basic authentification allows per request authentification.
If you want to add basic authentification to all the request of a Hurl file
you could use [`-u/--user` option].

## Sending Data

### Sending HTML Form Datas

```hurl
POST https://example.org/contact
[FormParams]
default: false
token: {{token}}
email: john.doe@rookie.org
number: 33611223344
```

[Doc](https://hurl.dev/docs/request.html#form-parameters)

### Sending Multipart Form Datas

```hurl
POST https://example.org/upload
[MultipartFormData]
field1: value1
field2: file,example.txt;
# On can specify the file content type:
field3: file,example.zip; application/zip
```

[Doc](https://hurl.dev/docs/request.html#multipart-form-data)

### Posting a JSON Body

With an inline JSON:

```hurl
POST https://example.org/api/tests
{
    "id": "456",
    "evaluate": true
}
```

[Doc](https://hurl.dev/docs/request.html#json-body)

With a local file:

```hurl
POST https://example.org/api/tests
Content-Type: application/json
file,data.json;
```

[Doc](https://hurl.dev/docs/request.html#file-body)

### Templating a JSON / XML Body

Using templates with [JSON body] or [XML body] is not currently supported in Hurl.
Besides, you can use templates in [raw string body] with variables to send a JSON or XML body:

~~~hurl
PUT https://example.org/api/hits
Content-Type: application/json
```
{
    "key0": "{{a_string}}",
    "key1": {{a_bool}},
    "key2": {{a_null}},
    "key3": {{a_number}}
}
```
~~~

Variables can be initialized via command line:

```shell
$ hurl --variable a_string=apple \
       --variable a_bool=true \
       --variable a_null=null \
       --variable a_number=42 \
       test.hurl
```

Resulting in a PUT request with the following JSON body:

```
{
    "key0": "apple",
    "key1": true,
    "key2": null,
    "key3": 42
}
```

[Doc](https://hurl.dev/docs/request.html#raw-string-body)

## Testing Response

### Testing Response Headers

Use implicit response asserts to test header values:

```hurl
GET https://example.org/index.html

HTTP/1.0 200
Set-Cookie: theme=light
Set-Cookie: sessionToken=abc123; Expires=Wed, 09 Jun 2021 10:18:14 GMT
```

[Doc](https://hurl.dev/docs/asserting-response.html#headers)


Or use explicit response asserts with [predicates]:

```hurl
GET https://example.org

HTTP/1.1 302
[Asserts]
header "Location" contains "www.example.net"
```

[Doc](https://hurl.dev/docs/asserting-response.html#header-assert)


### Testing REST Apis

Asserting JSON body response (node values, collection count etc...) with [JSONPath]:

```hurl
GET https://example.org/order
screencapability: low

HTTP/1.1 200
[Asserts]
jsonpath "$.validated" == true
jsonpath "$.userInfo.firstName" == "Franck"
jsonpath "$.userInfo.lastName" == "Herbert"
jsonpath "$.hasDevice" == false
jsonpath "$.links" count == 12
jsonpath "$.state" != null
jsonpath "$.order" matches "^order-\\d{8}$"
jsonpath "$.order" matches /^order-\d{8}$/     # Alternative syntax with regex litteral
```

[Doc](https://hurl.dev/docs/asserting-response.html#jsonpath-assert)


Testing status code:

```hurl
GET https://example.org/order/435

HTTP/1.1 200
```

[Doc](https://hurl.dev/docs/asserting-response.html#version-status)

```hurl
GET https://example.org/order/435

# Testing status code is in a 200-300 range
HTTP/1.1 *
[Asserts]
status >= 200
status < 300
```

[Doc](https://hurl.dev/docs/asserting-response.html#status-assert)


### Testing HTML Response

```hurl
GET https://example.org

HTTP/1.1 200
Content-Type: text/html; charset=UTF-8

[Asserts]
xpath "string(/html/head/title)" contains "Example" # Check title
xpath "count(//p)" == 2  # Check the number of p
xpath "//p" count == 2  # Similar assert for p
xpath "boolean(count(//h2))" == false  # Check there is no h2  
xpath "//h2" not exists  # Similar assert for h2
xpath "string(//div[1])" matches /Hello.*/
```

[Doc](https://hurl.dev/docs/asserting-response.html#xpath-assert)

### Testing Set-Cookie Attributes

```hurl
GET http://myserver.com/home

HTTP/1.0 200
[Asserts]
cookie "JSESSIONID" == "8400BAFE2F66443613DC38AE3D9D6239"
cookie "JSESSIONID[Value]" == "8400BAFE2F66443613DC38AE3D9D6239"
cookie "JSESSIONID[Expires]" contains "Wed, 13 Jan 2021"
cookie "JSESSIONID[Secure]" exists
cookie "JSESSIONID[HttpOnly]" exists
cookie "JSESSIONID[SameSite]" == "Lax"
```

[Doc](https://hurl.dev/docs/asserting-response.html#cookie-assert)

### Testing Bytes Content


Check the SHA-256 response body hash:

```hurl
GET https://example.org/data.tar.gz

HTTP/* *
[Asserts]
sha256 == hex,039058c6f2c0cb492c533b0a4d14ef77cc0f78abccced5287d84a1a2011cfb81;

# Man Page

## Name

hurl - run and test HTTP requests.


## Synopsis

**hurl** [options] [FILE...]


## Description

**Hurl** is an HTTP client that performs HTTP requests defined in a simple plain text format.

Hurl is very versatile, it enables to chain HTTP requests, capture values from HTTP responses and make asserts.

```
$ hurl session.hurl
```

If no input files are specified, input is read from stdin.

```
$ echo GET http://httpbin.org/get | hurl
    {
      "args": {},
      "headers": {
        "Accept": "*/*",
        "Accept-Encoding": "gzip",
        "Content-Length": "0",
        "Host": "httpbin.org",
        "User-Agent": "hurl/0.99.10",
        "X-Amzn-Trace-Id": "Root=1-5eedf4c7-520814d64e2f9249ea44e0"
      },
      "origin": "1.2.3.4",
      "url": "http://httpbin.org/get"
    }
```


Output goes to stdout by default. For output to a file, use the [`-o, --output`](#output) option:

```
$ hurl -o output input.hurl
```

By default, Hurl executes all HTTP requests and outputs the response body of the last HTTP call.

To have a test oriented output, you can use [`--test`](#test) option:

```
$ hurl --test *.hurl
```


## Hurl File Format

The Hurl file format is fully documented in [https://hurl.dev/docs/hurl-file.html](https://hurl.dev/docs/hurl-file.html)

It consists of one or several HTTP requests

```hurl
GET http:/example.org/endpoint1
GET http:/example.org/endpoint2
```


### Capturing values

A value from an HTTP response can be-reused for successive HTTP requests.

A typical example occurs with csrf tokens.

```hurl
GET https://example.org
HTTP/1.1 200
# Capture the CSRF token value from html body.
[Captures]
csrf_token: xpath "normalize-space(//meta[@name='_csrf_token']/@content)"

# Do the login !
POST https://example.org/login?user=toto&password=1234
X-CSRF-TOKEN: {{csrf_token}}
```

More information on captures here [https://hurl.dev/docs/capturing-response.html](https://hurl.dev/docs/capturing-response.html)

### Asserts

The HTTP response defined in the Hurl session are used to make asserts.

At the minimum, the response includes the asserts on the HTTP version and status code.

```hurl
GET http:/google.com
HTTP/1.1 301
```

It can also include asserts on the response headers

```hurl
GET http:/google.com
HTTP/1.1 301
Location: http://www.google.com
```

You can also include explicit asserts combining query and predicate

```hurl
GET http:/google.com
HTTP/1.1 301
[Asserts]
xpath "string(//title)" == "301 Moved"
```

Thanks to asserts, Hurl can be used as a testing tool to run scenarii.

More information on asserts here [https://hurl.dev/docs/asserting-response.html](https://hurl.dev/docs/asserting-response.html)

## Options

Options that exist in curl have exactly the same semantic. 

Options specified on the command line are defined for every Hurl file's entry.

For instance:

```
$ hurl --location foo.hurl
```

will follow redirection for each entry in `foo.hurl`. You can also define option only for a particular entry with an `[Options]` section. For instance, this Hurl file:

```hurl
GET https://google.com
HTTP/* 301

GET https://google.com
[Options]
location: true
HTTP/* 200
```

will follow redirection only for the second entry.

Option | Description
 --- | --- 
<a href="#cacert" id="cacert"><code>--cacert</code></a> | Tells curl to use the specified certificate file to verify the peer.<br/>The file may contain multiple CA certificates.<br/>The certificate(s) must be in PEM format.<br/>Normally curl is built to use a default file for this, so this option is typically used to alter that default file.<br/>
<a href="#color" id="color"><code>--color</code></a> | Colorize Output<br/>
<a href="#compressed" id="compressed"><code>--compressed</code></a> | Request a compressed response using one of the algorithms br, gzip, deflate and automatically decompress the content.<br/>
<a href="#connect-timeout" id="connect-timeout"><code>--connect-timeout &lt;seconds&gt;</code></a> | Maximum time in seconds that you allow Hurl's connection to take.<br/><br/>See also [`-m, --max-time`](#max-time) option.<br/>
<a href="#cookie" id="cookie"><code>-b, --cookie &lt;file&gt;</code></a> | Read cookies from file (using the Netscape cookie file format).<br/><br/>Combined with [`-c, --cookie-jar`](#cookie-jar), you can simulate a cookie storage between successive Hurl runs.<br/>
<a href="#cookie-jar" id="cookie-jar"><code>-c, --cookie-jar &lt;file&gt;</code></a> | Write cookies to FILE after running the session (only for one session).<br/>The file will be written using the Netscape cookie file format.<br/><br/>Combined with [`-b, --cookie`](#cookie), you can simulate a cookie storage between successive Hurl runs.<br/>
<a href="#fail-at-end" id="fail-at-end"><code>--fail-at-end</code></a> | Continue executing requests to the end of the Hurl file even when an assert error occurs.<br/>By default, Hurl exits after an assert error in the HTTP response.<br/><br/>Note that this option does not affect the behavior with multiple input Hurl files.<br/><br/>All the input files are executed independently. The result of one file does not affect the execution of the other Hurl files.<br/>
<a href="#file-root" id="file-root"><code>--file-root &lt;dir&gt;</code></a> | Set root filesystem to import files in Hurl. This is used for both files in multipart form data and request body.<br/>When this is not explicitly defined, the files are relative to the current directory in which Hurl is running.<br/>
<a href="#location" id="location"><code>-L, --location</code></a> | Follow redirect.  You can limit the amount of redirects to follow by using the [`--max-redirs`](#max-redirs) option.<br/>
<a href="#glob" id="glob"><code>--glob &lt;glob&gt;</code></a> | Specify input files that match the given glob pattern.<br/><br/>Multiple glob flags may be used. This flag supports common Unix glob patterns like *, ? and []. <br/>However, to avoid your shell accidentally expanding glob patterns before Hurl handles them, you must use single quotes or double quotes around each pattern.<br/>
<a href="#include" id="include"><code>-i, --include</code></a> | Include the HTTP headers in the output (last entry).<br/>
<a href="#ignore-asserts" id="ignore-asserts"><code>--ignore-asserts</code></a> | Ignore all asserts defined in the Hurl file.<br/>
<a href="#insecure" id="insecure"><code>-k, --insecure</code></a> | This option explicitly allows Hurl to perform "insecure" SSL connections and transfers.<br/>
<a href="#interactive" id="interactive"><code>--interactive</code></a> | Stop between requests.<br/>This is similar to a break point, You can then continue (Press C) or quit (Press Q).<br/>
<a href="#json" id="json"><code>--json</code></a> | Output each hurl file result to JSON. The format is very closed to HAR format. <br/>
<a href="#max-redirs" id="max-redirs"><code>--max-redirs &lt;num&gt;</code></a> | Set maximum number of redirection-followings allowed<br/>By default, the limit is set to 50 redirections. Set this option to -1 to make it unlimited.<br/>
<a href="#max-time" id="max-time"><code>-m, --max-time &lt;seconds&gt;</code></a> | Maximum time in seconds that you allow a request/response to take. This is the standard timeout.<br/><br/>See also [`--connect-timeout`](#connect-timeout) option.<br/>
<a href="#no-color" id="no-color"><code>--no-color</code></a> | Do not colorize output<br/>
<a href="#no-output" id="no-output"><code>--no-output</code></a> | Suppress output. By default, Hurl outputs the body of the last response.<br/>
<a href="#noproxy" id="noproxy"><code>--noproxy &lt;no-proxy-list&gt;</code></a> | Comma-separated list of hosts which do not use a proxy.<br/>Override value from Environment variable no_proxy.<br/>
<a href="#output" id="output"><code>-o, --output &lt;file&gt;</code></a> | Write output to <file> instead of stdout.<br/>
<a href="#progress" id="progress"><code>--progress</code></a> | Print filename and status for each test (on stderr)<br/><br/>Deprecated, use [`--test`](#test) or [`--json`](#json) instead.<br/>

## Environment

Environment variables can only be specified in lowercase.

Using an environment variable to set the proxy has the same effect as using the [`-x, --proxy`](#proxy) option.

Variable | Description
 --- | --- 
`http_proxy [protocol://]<host>[:port]` | Sets the proxy server to use for HTTP.<br/>
`https_proxy [protocol://]<host>[:port]` | Sets the proxy server to use for HTTPS.<br/>
`all_proxy [protocol://]<host>[:port]` | Sets the proxy server to use if no protocol-specific proxy is set.<br/>
`no_proxy <comma-separated list of hosts>` | List of host names that shouldn't go through any proxy.<br/>
`HURL_name value` | Define variable (name/value) to be used in Hurl templates. This is similar than [`--variable`](#variable) and [`--variables-file`](#variables-file) options.<br/>
`NO_COLOR` | When set to a non-empty string, do not colorize output (see [`--no-color`](#no-color) option).<br/>

## Exit Codes

Value | Description
 --- | --- 
`1` | Failed to parse command-line options.<br/>
`2` | Input File Parsing Error.<br/>
`3` | Runtime error (such as failure to connect to host).<br/>
`4` | Assert Error.<br/>
