I have code within a Flask application that uses JSONs in the request, and I can get the JSON object like so:
Request = request.get_json() This has been working fine, however I am trying to create unit tests using Python's unittest module and I'm having difficulty finding a way to send a JSON with the request.
response=self.app.post('/test_function', data=json.dumps(dict(foo = 'bar'))) This gives me:
>>> request.get_data() '{"foo": "bar"}' >>> request.get_json() None Flask seems to have a JSON argument where you can set json=dict(foo='bar') within the post request, but I don't know how to do that with the unittest module.

To post a JSON to the server using Python Requests Library, call the requests. post() method and pass the target URL as the first parameter and the JSON data with the json= parameter. The json= parameter takes a dictionary and automatically converts it to a JSON string.
To request JSON from a URL, you need to send an HTTP GET request to the server and provide the Accept: application/json request header with your request. The Accept header tells the server that our client is expecting JSON.
json() The json() method of the Request interface reads the request body and returns it as a promise that resolves with the result of parsing the body text as JSON .
Changing the post to
response=self.app.post('/test_function', data=json.dumps(dict(foo='bar')), content_type='application/json') fixed it.
