The Hurl team is happy to announce Hurl 1.8.0 ! .
# 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: HTTP/1.1 302
Hurl can be used to get data like curl, or as a testing tool for JSON/XML apis and HTML content.
So, what’s new in 1.8.0?
You can now retry requests which asserts and captures have failed. This way, you can write
polling scenarios or create robust tests even in flaky conditions. To activate retry, you can either use
--retry option (every request of the run can be retried), or you can target a specific request with an
Let’s say we have an API to create a ressource. Once created, we want to poll this resource and wait until it reaches a certain state.
First we create a new resource with a
POST request. We capture the id of the resource to be able to use it
in the following requests:
# Create a new job POST https://api.example.org/jobs HTTP/* 201 [Captures] job_id: jsonpath "$.id" [Asserts] jsonpath "$.state" == "RUNNING"
Then, we pull the resource with a
GET request and check its
state value. We’ve configured the
GET request to
be retried with an
[Options] section. The JSONPath assert tests the value of
state field. Because
of the retry option, the
GET request is going to be retried until
state’s value is
# ... # Pull job status until it is completed GET https://api.example.org/jobs/ [Options] retry: 10 HTTP/* 200 [Asserts] jsonpath "$.state" == "COMPLETED"
So, the full scenario looks like:
# Create a new job POST https://api.example.org/jobs HTTP/* 201 [Captures] job_id: jsonpath "$.id" [Asserts] jsonpath "$.state" == "RUNNING" # Pull job status until it is completed GET https://api.example.org/ [Options] retry: 10 HTTP/* 200 [Asserts] jsonpath "$.state" == "COMPLETED"
GET https://api.example.org/123456 [Options] retry: 10 retry-interval: 4000 HTTP/* 200
will poll until
https://api.example.org/123456 returns a
200 OK, with a 4 seconds delay between each retry.
Finally, one common need in shell script is to wait until a specific URL is ready and returns a 200 OK. This can be easily done now with Hurl:
$ echo -e 'GET https://example.org/health\nHTTP/* 200' | hurl --retry
# Check that HTTP is redirected to HTTPS: GET http://example.org [Options] location: true HTTP/* 200 [Asserts] url == "https://example.org"
In Hurl 1.7.0, we introduced
--very-verbose option to output request and response bodies. Now, when
very-verbose is used, Hurl displays debug logs from libcurl (prefixed with
**), allowing displaying SSL certificates infos for instance:
