Request POST JSON data in Python [duplicate]

Question

I want to make POST data with requests in Python.

This is the data, actually, I grab from Burp Suite (intercept HTTP request).

sessionid=xxxsesi&serverid=1&partner=xxxpartner&tradeoffermessage=&json_tra
deoffer={"newversion":true,"version":3,"me":{"assets":
[{"appid":0,"contextid":"2","amount":1,"assetid":"xxxasset"}],"currency":
[],"ready":false},"them":{"assets":[],"currency":
[],"ready":"false"}}&captcha=&trade_offer_create_params=
{"trade_offer_access_token":"xxxtoken"}

But if I try to write in requests POST Python, it always fails.

data = {
"sessionid": "xxxsession",
"serverid": 1,
"partner":"xxxpartner",
"tradeoffermessage": "",
"json_tradeoffer": {"newversion":True,"version":3,"me":{"assets":[{"appid":440,"contextid":"2","amount":1,"assetid":"xxxasset"}],"currency":[],"ready":False},"them":{"assets":[],"currency":[],"ready":False}},
"captcha": "",
"trade_offer_create_params": {"trade_offer_access_token":"xxxtoken"}
}

Can someone help me? Sorry for my bad English.

Answer 1

In Python post request is more complicated as compare to other requests.but here is the solution for post request in python.

Example#1: POST REQUEST

  >>> payload = {'key1': 'value1', 'key2': 'value2'}

>>> r = requests.post("http://httpbin.org/post", data=payload)
>>> print(r.text)
{
  ...
  "form": {
    "key2": "value2",
    "key1": "value1"
  },
  ...
}

Example#2: POST REQUEST

>>> 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'}

BUT IN YOUR SCENARIO

you're using the burp suite to get data and post data in python (I don't know which specific version of python are you using) but you should follow basic method of post request in python.if you're using the brup suite and must read the brup suite documentation

Here is the documentation link which'll explain you each step one by one and do keep an eye on the notes and TODOs while following the step (in your scenario).
