# What's Hurl? Hurl is a command line tool that runs 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. ```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 test HTTP responses. Different types of queries and predicates are supported, from [XPath] and [JSONPath] on body response, to assert on status code and response headers. Hurl Demo It is well adapted for REST / JSON APIs ```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 ``` HTML content ```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" GOOG HTTP/1.1 200 ``` Hurl can also be used to performance test HTTP endpoints: ```hurl GET https://example.org/api/v1/pets HTTP/1.0 200 [Asserts] duration < 1000 # Duration in ms ``` And response bytes ```hurl GET https://example.org/data.tar.gz HTTP/1.0 200 [Asserts] sha256 == hex,039058c6f2c0cb492c533b0a4d14ef77cc0f78abccced5287d84a1a2011cfb81; ``` # Why Hurl? # 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 libraries. With its text file format, Hurl adds syntactic sugar to run and test 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 ``` # Resources [License] [Blog] [Tutorial] [Documentation] [GitHub] [XPath]: https://en.wikipedia.org/wiki/XPath [JSONPath]: https://goessner.net/articles/JsonPath/ [Rust]: https://www.rust-lang.org [curl]: https://curl.se [the installation section]: /docs/installation.md [Feedback, suggestion, bugs or improvements]: https://github.com/Orange-OpenSource/hurl/issues [License]: /docs/license.md [Tutorial]: /docs/tutorial/your-first-hurl-file.md [Documentation]: /docs/installation.md [Blog]: blog.md [GitHub]: https://github.com/Orange-OpenSource/hurl [libcurl]: https://curl.se/libcurl/
