当cURL工作时，Python请求库不工作 [英] Python requests library is not working, while cURL is working

问题描述

我需要使用Python从Microsoft API检索JWT(JSON Web令牌)(请检查

I need to retrieve a JWT (JSON Web Token) from a Microsoft API using Python (check this API documentation for Microsoft Graph)

使用requests库的以下Python代码无法使用HTTP响应代码400，但是，等效的cURL命令也可以使用以返回包含JWT的JSON.

The following Python code using the requests library does not work giving HTTP response code 400, however, the equivalent cURL command does work giving back the expected JSON containing the JWT.

Python/requests代码:

Python / requests code:

tenant = "<MY_FOO_TENANT>"
token_url = "https://login.microsoftonline.com/{}/oauth2/v2.0/token".format(tenant)
http_headers = {
    'Content-Type':  'application/x-www-form-urlencoded',
}
http_query_params = {
    "client_id": "<MY_FOO_C_ID>",
    "scope": "<MY_FOO_SCOPE>",
    "client_secret": "<MY_FOO_C_SECRET>",
    "grant_type": "client_credentials",
}
http_response = requests.post(token_url, params=http_query_params, headers=http_headers)

cURL命令:

curl -v -X POST \
  --data-urlencode 'client_id=<MY_FOO_C_ID>' \
  --data-urlencode 'scope=<MY_FOO_SCOPE>' \
  --data-urlencode 'client_secret=<MY_FOO_C_SECRET>' \
  --data-urlencode 'grant_type=client_credentials' \
  -H 'Content-Type: application/x-www-form-urlencoded' \
  'https://login.microsoftonline.com/<MY_FOO_TENANT>/oauth2/v2.0/token'

从requests库的详细输出中，我可以看到它是对所有这些HTTP查询参数进行URL编码的，所以我倾向于认为这不是问题.

From the verbose output of the requests library I can see that it is URL encoding all those HTTP query parameters, so I tend to think that should not be the problem.

• Python实现有什么问题?
• 如何使其工作?

推荐答案

，您应将http_query_params作为data而不是params传递.尝试以下代码:

you should pass http_query_params as data instead of params. try the following code:

tenant = "<MY_FOO_TENANT>"
token_url = "https://login.microsoftonline.com/{}/oauth2/v2.0/token".format(tenant)
http_headers = {
    'Content-Type':  'application/x-www-form-urlencoded',
}
http_body = {
    "client_id": "<MY_FOO_C_ID>",
    "scope": "<MY_FOO_SCOPE>",
    "client_secret": "<MY_FOO_C_SECRET>",
    "grant_type": "client_credentials",
}
http_response = requests.post(token_url, data=http_body, headers=http_headers)
