hurl - run and test HTTP requests.


hurl [options] [FILE…]


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 | hurl
      "args": {},
      "headers": {
        "Accept": "*/*",
        "Accept-Encoding": "gzip",
        "Content-Length": "0",
        "Host": "",
        "User-Agent": "hurl/0.99.10",
        "X-Amzn-Trace-Id": "Root=1-5eedf4c7-520814d64e2f9249ea44e0"
      "origin": "",
      "url": ""

Output goes to stdout by default. For output to a file, use the -o option:

$ hurl -o output input.hurl

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


The Hurl file format is fully documented in

It consists of one or several HTTP requests

GET http:/
GET http:/

Capturing values

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

A typical example occurs with csrf tokens.

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

# Do the login !
X-CSRF-TOKEN: {{csrf_token}}


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.

GET http:/
HTTP/1.1 302

It can also include asserts on the response headers

GET http:/
HTTP/1.1 302

You can also include explicit asserts combining query and predicate

GET http:/
HTTP/1.1 302
xpath "//title" == "301 Moved"

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


Options that exist in curl have exactly the same semantic.

Option Description
--appendThis option can only be used with --json. It appends sessions to existing file instead of overwriting it. This is typically used in a CI pipeline.
--colorColorize Output
-b, --cookie Read cookies from file (using the Netscape cookie file format).

Combined with -c, --cookie-jar, you can simulate a cookie storage between successive Hurl runs.
--compressedRequest a compressed response using one of the algorithms br, gzip, deflate and automatically decompress the content.
--connect-timeout Maximum time in seconds that you allow Hurl’s connection to take.

See also -m, --max-time option.
-c, --cookie-jar Write cookies to FILE after running the session (only for one session). The file will be written using the Netscape cookie file format.

Combined with -b, --cookie,you can simulate a cookie storage between successive Hurl runs.
--fail-at-endContinue executing requests to the end of the Hurl file even when an assert error occurs. By default, Hurl exits after an assert error in the HTTP response.

Note that this option does not affect the behavior with multiple input Hurl files.

All the input files are executed independently. The result of one file does not affect the execution of the other Hurl files.
--file-root Set root filesystem to import files in Hurl. This is used for both files in multipart form data and request body. When this is not explicitly defined, the files are relative to the current directory in which Hurl is running.
-h, --helpUsage help. This lists all current command line options with a short description.
--html Generate html report in dir.

If you want to combine results from different Hurl executions in a unique html report, you must also use the options --json and --append.
-i, --includeInclude the HTTP headers in the output (last entry).
--interactiveStop between requests. This is similar to a break point, You can then continue (Press C) or quit (Press Q).
--json Write full session(s) to a json file. The format is very closed to HAR format.

By default, this file is overwritten by the current run execution. In order to append sessions to an existing json file, the option --append must be used. This is typically used in a CI pipeline.
-k, --insecureThis option explicitly allows Hurl to perform “insecure” SSL connections and transfers.
-L, --locationFollow redirect. You can limit the amount of redirects to follow by using the --max-redirs option.
-m, --max-time Maximum time in seconds that you allow a request/response to take. This is the standard timeout.

See also --connect-timeout option.
--max-redirs Set maximum number of redirection-followings allowed By default, the limit is set to 50 redirections. Set this option to -1 to make it unlimited.
--no-colorDo not colorize Output
--noproxy Comma-separated list of hosts which do not use a proxy. Override value from Environment variable no_proxy.
--to-entry Execute Hurl file to ENTRY_NUMBER (starting at 1). Ignore the remaining of the file. It is useful for debugging a session.
-o, --output Write output to instead of stdout.
--progressPrint filename and status for each test
--summaryPrint test metrics at the end of the run
--testActivate test mode; equals --output /dev/null --progress --summary
-x, --proxy [protocol://]host[:port]Use the specified proxy.
-u, --user Add basic Authentication header to each request.
--variable Define variable (name/value) to be used in Hurl templates. Only string values can be defined.
--variables-file Set properties file in which your define your variables.

Each variable is defined as name=value exactly as with --variable option.

Note that defining a variable twice produces an error.
-v, --verboseTurn on verbose output on standard error stream Useful for debugging.

A line starting with ‘>’ means data sent by Hurl. A line staring with ‘<’ means data received by Hurl. A line starting with ‘*’ means additional info provided by Hurl.

If you only want HTTP headers in the output, -i, --include might be the option you’re looking for.
-V, --versionPrints version information


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 option.

http_proxy [protocol://][:port]

Sets the proxy server to use for HTTP.

https_proxy [protocol://][:port]

Sets the proxy server to use for HTTPS.

all_proxy [protocol://][:port]

Sets the proxy server to use if no protocol-specific proxy is set.


list of host names that shouldn’t go through any proxy.
