How to POST JSON data with Python Requests?


Starting with Requests version 2.4.2, you can use the json= parameter (which takes a dictionary) instead of data= (which takes a string) in the call:

>>> import requests>>> r = requests.post('http://httpbin.org/post', json={"key": "value"})>>> r.status_code200>>> r.json(){'args': {}, 'data': '{"key": "value"}', 'files': {}, 'form': {}, 'headers': {'Accept': '*/*',             'Accept-Encoding': 'gzip, deflate',             'Connection': 'close',             'Content-Length': '16',             'Content-Type': 'application/json',             'Host': 'httpbin.org',             'User-Agent': 'python-requests/2.4.3 CPython/3.4.0',             'X-Request-Id': 'xx-xx-xx'}, 'json': {'key': 'value'}, 'origin': 'x.x.x.x', 'url': 'http://httpbin.org/post'}


It turns out I was missing the header information. The following works:

url = "http://localhost:8080"data = {'sender': 'Alice', 'receiver': 'Bob', 'message': 'We did it!'}headers = {'Content-type': 'application/json', 'Accept': 'text/plain'}r = requests.post(url, data=json.dumps(data), headers=headers)


From requests 2.4.2 (https://pypi.python.org/pypi/requests), the "json" parameter is supported. No need to specify "Content-Type". So the shorter version:

requests.post('http://httpbin.org/post', json={'test': 'cheers'})
