I need to POST a JSON from a client to a server. I'm using Python 2.7.1 and simplejson. The client is using Requests. The server is CherryPy. I can GET a hard-coded JSON from the server (code not shown), but when I try to POST a JSON to the server, I get "400 Bad Request".
Here is my client code:
data = {'sender': 'Alice',
'receiver': 'Bob',
'message': 'We did it!'}
data_json = simplejson.dumps(data)
payload = {'json_payload': data_json}
r = requests.post("http://localhost:8080", data=payload)
Here is the server code.
class Root(object):
def __init__(self, content):
self.content = content
print self.content # this works
exposed = True
def GET(self):
cherrypy.response.headers['Content-Type'] = 'application/json'
return simplejson.dumps(self.content)
def POST(self):
self.content = simplejson.loads(cherrypy.request.body.read())
Any ideas?
As of Requests version 2.4.2 and onwards, you can alternatively use 'json' parameter in the call which makes it simpler.
>>> import requests
>>> r = requests.post('http://httpbin.org/post', json={"key": "value"})
>>> r.status_code
200
>>> 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'}
