从MS Graph API获取联系人时找不到资源 [英] Resource Not Found While fetching contacts from MS Graph API

问题描述

我在github示例下面尝试了Azure AD身份验证，并成功获取了具有正确回调URL的访问令牌.

I tried below github sample for Azure AD Authentication and successfully getting access token with proper call back URL.

https://github.com/Microsoft/BotBuilder-Samples/tree/master/samples/csharp_dotnetcore/18.bot-authentication

根据在 https://apps.dev.microsoft中创建的应用程序修改和配置的Web.config密钥. com

  <add key="ActiveDirectory.Mode" value="v1" />
<add key="ActiveDirectory.ResourceId" value="https://graph.microsoft.com" />
<add key="ActiveDirectory.EndpointUrl" value="https://login.microsoftonline.com" />
<add key="ActiveDirectory.Tenant" value="xyz-xyz" />
<add key="ActiveDirectory.ClientId" value="xyz-xyz" />
<add key="ActiveDirectory.ClientSecret" value="xyz-xyz" />
 <add key="ActiveDirectory.RedirectUrl" value="http://localhost:3979/api/Callback" />
<add key="ActiveDirectory.Scopes" value="Calendars.Read,Calendars.ReadWrite,Contacts.Read,Contacts.ReadWrite,Mail.Read,Mail.ReadWrite,User.Read" />

我已经越过收到了 jwt.ms 的检查访问令牌.这是一个有效令牌，其作用域定义与我在web.config中定义的完全相同.

I had crossed checked access token that i received jwt.ms. It is a valid token with scopes defined exactly as i defined in web.config.

我可以通过传递令牌来从API获取用户个人资料数据，但是在尝试调用用户的联系人"时，却遇到了错误.

I am able to get User Profile data from API by passing token but while trying to call "Contacts" of user, I am getting below error.

{
"error": {
    "code": "ResourceNotFound",
    "message": "Resource could not be discovered.",
    "innerError": {
        "request-id": "6f0f3ec9-76c9-4662-ac25-0bc73f887268",
        "date": "2019-03-02T17:23:35"
    }
}

}

代码调用联系人API调用.

Code calling Contact API call.

   //Get Logged in user contacts
    public async Task<IUserContactsCollectionPage> GetMyContactsAsync()
    {
        var graphClient = GetAuthenticatedClient();
        IUserContactsCollectionPage contacts = await graphClient.Me.Contacts.Request().GetAsync();
        return contacts;
    }

仅供参考:在模拟器中显示登录卡授权示例URL如下所示

FYI: Displayed Sign In card in emulator Authorize sample URL is like below

https://login.microsoftonline.com/a76b43b0-3088-4c56-ba0d-01f317b1f18c/oauth2/authorize?resource=https:%2F%2Fgraph.microsoft.com&client_id=XYZ&response_type=code&haschrome=1&redirect_uri=http:%2F%2Flocalhost:3979%2Fapi%2FCallback&x-client-SKU=PCL.Desktop&x-client-Ver=3.13.9.1126&x-client-CPU=x64&x-client-OS=Microsoft+Windows+NT+10.0.16299.0&state=<stateID>
