NAME

hurl - run and test HTTP requests.

SYNOPSIS

hurl [options] [FILE...]

DESCRIPTION

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

It can chain requests, capture values and evaluate queries on headers and body response. Hurl is very versatile, it can be used for fetching data and testing HTTP sessions: HTML content, REST / SOAP / GraphQL APIs, or any other XML / JSON based APIs.

$ hurl session.hurl

If no input files are specified, input is read from stdin.

$ echo GET http://httpbin.org/get | hurl
    {
      "args": {},
      "headers": {
        "Accept": "*/*",
        "Accept-Encoding": "gzip",
        "Content-Length": "0",
        "Host": "httpbin.org",
        "User-Agent": "hurl/0.99.10",
        "X-Amzn-Trace-Id": "Root=1-5eedf4c7-520814d64e2f9249ea44e0"
      },
      "origin": "1.2.3.4",
      "url": "http://httpbin.org/get"
    }

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

$ hurl -o output input.hurl

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

To have a test oriented output, you can use --test option:

$ hurl --test *.hurl

HURL FILE FORMAT

The Hurl file format is fully documented in https://hurl.dev/docs/hurl-file.html

It consists of one or several HTTP requests

GET http:/example.org/endpoint1
GET http:/example.org/endpoint2

Capturing values

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

A typical example occurs with CSRF tokens.

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

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

More information on captures can be found here https://hurl.dev/docs/capturing-response.html

Asserts

The HTTP response defined in the Hurl file are used to make asserts. Responses are optional.

At the minimum, response includes assert on the HTTP status code.

GET http:/example.org
HTTP 301

It can also include asserts on the response headers

GET http:/example.org
HTTP 301
Location: http://www.example.org

Explicit asserts can be included by combining a query and a predicate

GET http:/example.org
HTTP 301
[Asserts]
xpath "string(//title)" == "301 Moved"

With the addition of asserts, Hurl can be used as a testing tool to run scenarios.

More information on asserts can be found here https://hurl.dev/docs/asserting-response.html

OPTIONS

Options that exist in curl have exactly the same semantics.

Options specified on the command line are defined for every Hurl file's entry.

For instance:

$ hurl --location foo.hurl

will follow redirection for each entry in foo.hurl. You can also define an option only for a particular entry with an [Options] section. For instance, this Hurl file:

GET https://example.org
HTTP 301

GET https://example.org
[Options]
location: true
HTTP 200

will follow a redirection only for the second entry.

--cacert

Specifies the certificate file for peer verification. The file may contain multiple CA certificates and must be in PEM format. Normally Hurl is built to use a default file for this, so this option is typically used to alter that default file.

-E, --cert <CERTIFICATE[:PASSWORD]>

Client certificate file and password.

See also --key.

--color

Colorize debug output (the HTTP response output is not colorized).

--compressed

Request 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.

--connect-to HOST1:PORT1:HOST2:PORT2

For a request to the given HOST1:PORT1 pair, connect to HOST2:PORT2 instead. This option can be used several times in a command line.

See also --resolve.

-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.

-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-end

Continue 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 file system 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.

-L, --location

Follow redirect. To limit the amount of redirects to follow use the --max-redirs option

--glob

Specify input files that match the given glob pattern.

Multiple glob flags may be used. This flag supports common Unix glob patterns like *, ? and []. However, to avoid your shell accidentally expanding glob patterns before Hurl handles them, you must use single quotes or double quotes around each pattern.

-i, --include

Include the HTTP headers in the output (last entry).

--ignore-asserts

Ignore all asserts defined in the Hurl file.

-k, --insecure

This option explicitly allows Hurl to perform "insecure" SSL connections and transfers.

--interactive

Stop between requests. This is similar to a break point, You can then continue (Press C) or quit (Press Q).

--json

Output each hurl file result to JSON. The format is very closed to HAR format.

--key

Private key file name.

--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.

-m, --max-time

Maximum time in seconds that you allow a request/response to take. This is the standard timeout.

See also --connect-timeout.

--no-color

Do not colorize output.

--no-output

Suppress output. By default, Hurl outputs the body of the last response.

--noproxy <HOST(S)>

Comma-separated list of hosts which do not use a proxy. Override value from Environment variable no_proxy.

-o, --output

Write output to FILE instead of stdout.

-x, --proxy <[PROTOCOL://]HOST[:PORT]>

Use the specified proxy.

--report-junit

Generate JUnit File.

If the FILE report already exists, it will be updated with the new test results.

--report-html

Generate HTML report in DIR.

If the HTML report already exists, it will be updated with the new test results.

--resolve HOST:PORT:ADDR {#resolve} HOST:PORT:ADDR

Provide a custom address for a specific host and port pair. Using this, you can make the Hurl requests(s) use a specified address and prevent the otherwise normally resolved address to be used. Consider it a sort of /etc/hosts alternative provided on the command line.

--retry

Retry requests if any error occurs (asserts, captures, runtimes etc...).

--retry-interval

Duration in milliseconds between each retry. Default is 1000 ms.

--retry-max-count

Maximum number of retries. Set this option to -1 to make it unlimited. Default is 10.

--ssl-no-revoke

(Windows) This option tells Hurl to disable certificate revocation checks. WARNING: this option loosens the SSL security, and by using this flag you ask for exactly that.

--test

Activate test mode: with this, the HTTP response is not outputted anymore, progress is reported for each Hurl file tested, and a text summary is displayed when all files have been run.

--to-entry <ENTRY_NUMBER>

Execute Hurl file to ENTRY_NUMBER (starting at 1). Ignore the remaining of the file. It is useful for debugging a session.

-u, --user USER:PASSWORD

Add basic Authentication header to each request.

-A, --user-agent

Specify the User-Agent string to send to the HTTP server.

--variable <NAME=VALUE>

Define variable (name/value) to be used in Hurl templates.

--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, --verbose

Turn 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.

--very-verbose

Turn on more verbose output on standard error stream.

In contrast to --verbose option, this option outputs the full HTTP body request and response on standard error. In addition, lines starting with '**' are libcurl debug logs.

-h, --help

Usage help. This lists all current command line options with a short description.

-V, --version

Prints version information

ENVIRONMENT

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.

no_proxy

List of host names that shouldn't go through any proxy.

HURL_name value

Define variable (name/value) to be used in Hurl templates. This is similar than --variable and --variables-file options.

NO_COLOR

When set to a non-empty string, do not colorize output (see --no-color option).

EXIT CODES

0

Success.

1

Failed to parse command-line options.

2

Input File Parsing Error.

3

Runtime error (such as failure to connect to host).

4

Assert Error.
