为什么为 Microsoft Graph api 请求持有者访问令牌不起作用？
Why is requesting a bearer access token for microsoft graph api not working?
我正在尝试接收访问令牌以用作 Microsoft Graph api 休息调用的授权持有者令牌，所有这些都在 mendix 中。我遵循本指南 -> (https://docs.microsoft.com/en-us/graph/auth-v2-user)，但在第 3 步，在使用我的 Microsoft 帐户登录并接受权限后尝试使用从第 2 步收到的代码时，我遇到了一条错误消息。
这是错误：
An error has occurred while handling the request. [User 'lenny' with session id '9950dffb-XXXX-XXXX-XXXX-XXXXXXXX1d29' and roles 'Mitarbeiter']

我不确定导致错误的原因。有没有办法来解决这个问题？如果需要，我可以提供有关该程序的更多信息。
我按照相同的指南 Get access on behalf of a user - Microsoft Graph | Microsoft Docs 生成了一个访问令牌，用作 Microsoft Graph 的授权持有者令牌 API 使用 Postman 进行休息调用，它对我有用。
使用 Microsoft 帐户登录并给予用户同意后，我们将收到一个代码。
在 Azure Active Directory 的应用程序注册中转到您的应用程序 --> 单击身份验证 --> 根据您的应用程序要求选中访问令牌和 ID 令牌 --> 单击保存
要获取客户端密码，请在 Azure Active Directory 的应用程序注册中转到您的应用程序 --> 单击证书和密码 --> 在客户端密码下，单击新客户端密码 --> 提供描述和单击添加 --> 复制该值并将其保存在某处，因为它是一次性可读的。
现在，我们可以提出一个 POST 请求，如下所示：
POST https://login.microsoftonline.com/{tenant-id}/oauth2/v2.0/token
Headers :
Content-Type: application/x-www-form-urlencoded
Body :
client_id: App Client ID
grant_type: authorization_code
scope: user.read%20mail.read
code: Code received in the second step
client_secret: Client Secret Generated in the App
现在，您将能够收到一个访问令牌以用作授权持有者令牌。
注意 ：我没有机会在 Mendix
中进行相同的测试
我正在尝试接收访问令牌以用作 Microsoft Graph api 休息调用的授权持有者令牌，所有这些都在 mendix 中。我遵循本指南 -> (https://docs.microsoft.com/en-us/graph/auth-v2-user)，但在第 3 步，在使用我的 Microsoft 帐户登录并接受权限后尝试使用从第 2 步收到的代码时，我遇到了一条错误消息。
这是错误：
An error has occurred while handling the request. [User 'lenny' with session id '9950dffb-XXXX-XXXX-XXXX-XXXXXXXX1d29' and roles 'Mitarbeiter']

我不确定导致错误的原因。有没有办法来解决这个问题？如果需要，我可以提供有关该程序的更多信息。
我按照相同的指南 Get access on behalf of a user - Microsoft Graph | Microsoft Docs 生成了一个访问令牌，用作 Microsoft Graph 的授权持有者令牌 API 使用 Postman 进行休息调用，它对我有用。
使用 Microsoft 帐户登录并给予用户同意后，我们将收到一个代码。
在 Azure Active Directory 的应用程序注册中转到您的应用程序 --> 单击身份验证 --> 根据您的应用程序要求选中访问令牌和 ID 令牌 --> 单击保存
要获取客户端密码，请在 Azure Active Directory 的应用程序注册中转到您的应用程序 --> 单击证书和密码 --> 在客户端密码下，单击新客户端密码 --> 提供描述和单击添加 --> 复制该值并将其保存在某处，因为它是一次性可读的。
现在，我们可以提出一个 POST 请求，如下所示：
POST https://login.microsoftonline.com/{tenant-id}/oauth2/v2.0/token
Headers :
Content-Type: application/x-www-form-urlencoded
Body :
client_id: App Client ID
grant_type: authorization_code
scope: user.read%20mail.read
code: Code received in the second step
client_secret: Client Secret Generated in the App
现在，您将能够收到一个访问令牌以用作授权持有者令牌。
注意 ：我没有机会在 Mendix
中进行相同的测试
