在C#中通过Microsoft Graph API在Microsoft团队常规通道中发布消息时出现Getting For

Question

我正试图使用C#代码通过Microsoft Graph API在Microsoft Teams的常规渠道中发布消息，但出现以下错误：

代码：禁止消息：禁止内部错误：AdditionalData:日期：2020-09-21T12:32:20请求id:242cabdf-da4f-4633-8161-621b8a27d4a0客户端请求id：242电缆-da4f-4633-8161-621b8a27d4a0客户端请求Id：242电缆-da4f-4633-8161-621b8a27d4a0

代码如下：

string userName = ConfigurationManager.AppSettings["UserName"];
string password = ConfigurationManager.AppSettings["Password"];
System.Security.SecureString passWordSecureString = new System.Security.SecureString();
foreach (char c in password.ToCharArray()) passWordSecureString.AppendChar(c);
var clientId = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx";
var tenantId = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx";
string[] scopes = { "ChannelMessage.Send", "Group.ReadWrite.All", "User.Read" };
IPublicClientApplication publicClientApplication = PublicClientApplicationBuilder
.Create(clientId)
.WithTenantId(tenantId)
.Build();
//creating the graph user context.
UsernamePasswordProvider authProvider = new UsernamePasswordProvider(publicClientApplication, scopes);
GraphServiceClient graphServiceClient = new GraphServiceClient(authProvider);
var user = await graphServiceClient.Me.Request()
.WithUsernamePassword(userName, passWordSecureString)
.GetAsync();
var chatMessage = new ChatMessage
{
Body = new ItemBody
{
Content = "Hello world From Console App"
},
From = new IdentitySet()
{
User = new Identity()
{
Id = "{user_Id}",
DisplayName = "FirstName LastName",
AdditionalData = new Dictionary<string, object>()
{
{ "userIdentityType", "aadUser" }
},
}
},
};
try
{
await graphServiceClient.Teams["{public_team_id}"].Channels["{channel_id}"].Messages
.Request()
.AddAsync(chatMessage);
}
catch (Exception exc)
{
Console.WriteLine("Error : " + exc.Message);
}

事实上，用户不是这个特定公共团队的一部分，所以我认为这就是为什么它给出了这个禁止的错误。有人能建议在用户不是该团队成员/所有者的特定团队频道中发布消息的代码吗？

如果你想向团队发帖，你肯定需要某种访问权限，但传入的webhook绝对是你最简单的解决方案。
