Answer 1

对https://login.microsoftonline.com/common/oauth2/v2.0/authorize的来电是HTTP GET，而不是POST。回调函数采用授权代码并向POST发出https://login.microsoftonline.com/common/oauth2/v2.0/token。

初始GET的原型是（可读性新线）：

https://login.microsoftonline.com/common/oauth2/v2.0/authorize?
client_id=[APPLICATION ID]&
response_type=code&
redirect_uri=[REDIRECT URI]&
scope=[SCOPE]

第二阶段发出POST。那个原型是：

POST URL: https://login.microsoftonline.com/common/oauth2/v2.0/token
POST HEADER: Content-Type: application/x-www-form-urlencoded
POST BODY: grant_type=authorization_code&code=[AUTHORIZATION CODE]&
           client_id=[APPLICATION ID]&client_secret=[PASSWORD]
           &scope=[SCOPE]&redirect_uri=[REDIRECT URI]

同样不是这不是JSON，Content-Type是application/x-www-form-urlencoded。

前段时间我写了一篇文章，通过使用v2端点的授权代码流程，您可能会发现它很有帮助：Microsoft v2 Endpoint Primer

Answer 2

https://login.microsoftonline.com/{{tenant_id}}/oauth2/token

删除 v2.0 版本并尝试。我有同样的错误代码

"error_codes": [ 70011 ], 所以它可以解决您的问题

invalid_scope错误AADSTS70011，为什么我收到此错误
