How To Post Complex Type To Wcf Using Python's Requests?

Solution 1:

You need to send JSON in the POST body, but you are attaching it to the query parameters instead.

Use data instead, and only encode the outer structure:

result=req.post(wsAddr+methodPath,
                data=json.dumps({'composite': cType}),
                headers=headers)

If you encoded cType, you'd send a JSON-encoded string containing another JSON-encoded string, which in turn contains your cType dictionary.
