使用 Python 请求获取令牌

Question

For the login on one of my Reoline cameras I need a token, which I can retrieve with CURL:

curl -d '[{"cmd": "Login", "action": 0, "param": {"User": {"userName": "admin", "password": "XXX"}}}]' 10.0.1.241/cgi-bin/api.cgi?cmd=Login&token=null

Delivery:

[{
  "cmd" : "Login",
  "code" : 0,
  "value" : {
     "Token" : {
        "leaseTime" : 3599,
        "name" : "b5ada7618176225"
     }
  }}]

But I want to perform this token retrieval in Python and fail:

    import requests
    url_WZ = 'http://10.0.1.241/cgi-bin/api.cgi?cmd=Login'
    payload = [{"cmd": "Login", "action": 0, "param": {"User": {"userName": "admin", "password": "XXX"}}}]

    r = requests.post(url=url_WZ, params=payload)

I get the following error message:

    Traceback (most recent call last):
      File "/Users/hubobel/Documents/Python/HubobelsPython/Reolink.py", line 8, in <module>
        r = requests.post(url=url_WZ, params=payload)

      File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/requests/models.py", line 97, in _encode_params
        for k, vs in to_key_val_list(data):
    ValueError: too many values to unpack (expected 2)

Process finished with exit code 1

It would be nice if I could find help for this.

Many greetings

This is my working solution:

import requests

url_WZ = 'http://10.0.1.241/cgi-bin/api.cgi?cmd=Login'
payload = '[{"cmd": "Login", "action": 0, "param": {"User": {"userName": "admin", "password": "XXX"}}}]'
r = requests.post(url=url_WZ, data=payload)
data = r.json()
print(data)
