Microsoft MSAL是否具有“资源所有者密码凭据授予"授权支持?

问题描述

MSAL是否具有资源所有者密码凭据授予授权[https://docs.microsoft.com/en-us/azure/active-directory/develop/v2-oauth-ropc]支持?

Does MSAL have Resource Owner Password Credentials Grant authorization[https://docs.microsoft.com/en-us/azure/active-directory/develop/v2-oauth-ropc] support?

推荐答案

是的，适用于Python的MSAL支持ROPC流(资源所有者密码凭据授予)，示例此处.

Yes, MSAL for Python supports ROPC flow(Resource Owner Password Credentials Grant), sample here.

"""
The configuration file would look like this:
{
    "authority": "https://login.microsoftonline.com/organizations",
    "client_id": "your_client_id",
    "username": "your_username@your_tenant.com",
    "password": "This is a sample only. You better NOT persist your password.",
    "scope": ["User.ReadBasic.All"],
        // You can find the other permission names from this document
        // https://docs.microsoft.com/en-us/graph/permissions-reference
    "endpoint": "https://graph.microsoft.com/v1.0/users"
        // You can find more Microsoft Graph API endpoints from Graph Explorer
        // https://developer.microsoft.com/en-us/graph/graph-explorer
}
You can then run this sample with a JSON configuration file:
    python sample.py parameters.json
