Samples

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

$ 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:

$ hurl --test sample.hurl

You can check Hurl tests suite for more samples.

Getting Data

A simple GET:

GET https://example.org

Doc

HTTP Headers

A simple GET with headers:

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

Query Params

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

Or:

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

Doc

Basic Authentication

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

Doc

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

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

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

Sending Data

Sending HTML Form Data

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

Doc

Sending Multipart Form Data

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

Doc

Multipart forms can also be sent with a multiline string body:

POST https://example.org/upload
Content-Type: multipart/form-data; boundary="boundary"
```
--boundary
Content-Disposition: form-data; name="key1"

value1
--boundary
Content-Disposition: form-data; name="upload1"; filename="data.txt"
Content-Type: text/plain

Hello World!
--boundary
Content-Disposition: form-data; name="upload2"; filename="data.html"
Content-Type: text/html

<div>Hello <b>World</b>!</div>
--boundary--
```

In that case, files have to be inlined in the Hurl file.

Doc

Posting a JSON Body

With an inline JSON:

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

Doc

With a local file:

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

Doc

Templating a JSON Body

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:

$ 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

Templating a XML Body

Using templates with XML body is not currently supported in Hurl. You can use templates in XML multiline string body with variables to send a variable XML body:

POST https://example.org/echo/post/xml
```xml
<?xml version="1.0" encoding="utf-8"?>
<Request>
    <Login>{{login}}</Login>
    <Password>{{password}}</Password>
</Request>
```

Doc

Using GraphQL Query

A simple GraphQL query:

POST https://example.org/starwars/graphql
```graphql
{
  human(id: "1000") {
    name
    height(unit: FOOT)
  }
}
```

A GraphQL query with variables:

POST https://example.org/starwars/graphql
```graphql
query Hero($episode: Episode, $withFriends: Boolean!) {
  hero(episode: $episode) {
    name
    friends @include(if: $withFriends) {
      name
    }
  }
}

variables {
  "episode": "JEDI",
  "withFriends": false
}
```

GraphQL queries can also use Hurl templates.

Testing Response

Testing Response Headers

Use implicit response asserts to test header values:

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

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

Or use explicit response asserts with predicates:

GET https://example.org

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