# Response
|
|
|
|
## Definition
|
|
|
|
Responses can be used to capture values to perform subsequent requests, or add asserts to HTTP responses. Response on
|
|
requests are optional, a Hurl file can just consist of a sequence of [requests].
|
|
|
|
A response describes the expected HTTP response, with mandatory [version and status], followed by optional [headers],
|
|
[captures], [asserts] and [body]. Assertions in the expected HTTP response describe values of the received HTTP response.
|
|
Captures capture values from the received HTTP response and populate a set of named variables that can be used
|
|
in the following entries.
|
|
|
|
## Example
|
|
|
|
```hurl
|
|
GET https://example.org
|
|
|
|
HTTP 200
|
|
Last-Modified: Wed, 21 Oct 2015 07:28:00 GMT
|
|
[Asserts]
|
|
xpath "normalize-space(//head/title)" startsWith "Welcome"
|
|
xpath "//li" count == 18
|
|
```

## Capture and Assertion
|
|
|
|
With the response section, one can optionally [capture value from headers, body],
|
|
or [add assert on status code, body or headers].
|
|
|
|
### Body compression
|
|
|
|
Hurl outputs the raw HTTP body to stdout by default. If response body is compressed (using [br, gzip, deflate]),
|
|
the binary stream is output, without any modification. One can use [`--compressed` option]
|
|
to request a compressed response and automatically get the decompressed body.
|
|
|
|
Captures and asserts work automatically on the decompressed body, so you can request compressed data (using [`Accept-Encoding`]
|
|
header by example) and add assert and captures on the decoded body as if there weren't any compression.
