What's Hurl?

Hurl is a command line tool that performs HTTP requests defined in a simple plain text format.

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

# Get home:
GET https://example.net

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

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

HTTP/1.1 302

Chaining multiple requests is easy:

GET https://api.example.net/health
GET https://api.example.net/health
GET https://api.example.net/health
GET https://api.example.net/health

Also an HTTP Test Tool

Hurl can run HTTP requests but can also be used to test HTTP responses. Different type of queries and predicates are supported, from XPath and JSONPath on body response, to assert on status code and response headers.

GET https://example.net

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

It is well adapted for REST/json apis

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

HTTP/1.1 200
[Asserts]
jsonpath "$.status" equals "RUNNING"      # Check the status code
jsonpath "$.tests" countEquals 25         # Check the number of items

and even SOAP apis

POST https://example.net/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="http://www.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

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:

PUT https://api.example.net/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 key0=apple --variable key1=true --variable key2=null --variable key3=42 test.hurl

Resulting in a PUT request with the following JSON body:

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