request() got an unexpected keyword argument 'json'

Question

I need to send data as json with requests module in Python.

For example:

import json
import requests
f = requests.Session()
data = {
    "from_date": "{}".format(from_date),
    "to_date": "{}".format(to_date),
    "Action": "Search"
}

get_data = f.post(URL, json=data, timeout=30, verify=False)

But after run this code, it showed this error:

get_data = f.post(URL, json=data, timeout=30, verify=False)
File "/usr/lib/python2.7/dist-packages/requests/sessions.py", line 497, in post
return self.request('POST', url, data=data, **kwargs)
TypeError: request() got an unexpected keyword argument 'json'

I'm on Ubuntu 16.04 and my Python version is 2.7.6

How to issue this problem?

Solution

your data is a dict, you should convert it to json format like this:

json.dumps(data)

import json
import requests
f = requests.Session()

headers = {'content-type': 'application/json'}
my_data = {
"from_date": "{}".format(from_date),
"to_date": "{}".format(to_date),
"Action": "Search"
 }

get_data = f.post(URL, data=json.dumps(my_data), timeout=30, headers=headers, verify=False)
