DEPRECATED: Please use Datagrepper instead now.

hrf is a tiny Flask application that accepts JSON blobs from the fedmsg bus via POST requests and converts them into human readable strings that can be used to display the information.

hrf takes JSON data in a POST request. It can take either a single JSON object or a list of JSON objects.

In both cases it will return a JSON object back, which contains one entry: results, which itself contains a list.

If you pass a single JSON object, the results list will, obviously, only contain one element -- but a list is always returned. This is intentional and done for consistency, so that apps using hrf don't have to special-case.

The list you get back in results will match the order of the JSON list you provided, if you provided one.

You can POST to /all in the same way, except that then results will be a list of objects, which is useful if you need multiple bits of information at once.

Noteworthy (for users):

Generally, if you need data for multiple messages, try to POST as much as you can at a time, because making a new HTTP connection to the app is expensive (for your app). You will create a much better and faster UX by doing this. Do not spawn a new connection to the app for each message in a batch, for example. Turn them into a JSON list and send that. It is to your benefit.

Also, try to gzip your data where possible, for another speedup.

Run tests with: PYTHONPATH=$(pwd)/hrf python tests/tests.py
