我需要使用 Graph API 將聊天訊息發送到MS Teams頻道，在此處記錄。
我從擁有所需權限的應用注冊中檢索令牌：
- ChannelMessage.Send（委托）
- ChannelMessage.Send（應用程式）
權限有Admin Consent。
這是獲取令牌的代碼C#：
var scopes = new[] {
"https://graph.microsoft.com/.default",
};
var tenantId = "602*********************************";
var clientId = "634*********************************";
var clientSecret = "DfV*************************************";
var options = new TokenCredentialOptions
{
AuthorityHost = AzureAuthorityHosts.AzurePublicCloud
};
var clientSecretCredential = new ClientSecretCredential(
tenantId, clientId, clientSecret, options);
var token = clientSecretCredential.GetToken(new TokenRequestContext(scopes)).Token;
我使用Postman來更好地檢查回應。這是POST請求的 URL：
https://graph.microsoft.com/v1.0/teams/991*********************************/channels/19:9*********************************@thread.tacv2/messages
Authorization標頭使用C# 代碼獲取的令牌設定，有效負載如下：
{
"createdDateTime": "2022-03-07T17:47:11.7429830Z",
"from": {
"user": {
"id": "2a7*********************************",
"displayName": "User display name",
"userIdentityType": "aadUser"
}
},
"body": {
"contentType": "html",
"content": "Hello Teams!"
}
}
This REST API call perfectly works with Graph Explorer when logged as a tenant user (using only the body property). With the App Registration token and additional properties I get the following response with HTTP status code 403 Forbidden:
{
"error": {
"code": "Forbidden",
"message": "{\"errorCode\":209,\"message\":\"{\\r\\n \\\"subCode\\\": \\\"MessageWritesBlocked\\\",\\r\\n \\\"details\\\": \\\"Thread is not marked for import\\\",\\r\\n \\\"errorCode\\\": null,\\r\\n \\\"errorSubCode\\\": null\\r\\n}\"}",
"innerError": {
"date": "2022-03-07T17:47:34",
"request-id": "e0ab5c7b-b64b-4c44-81e3-cc91b344403c",
"client-request-id": "e0ab5c7b-b64b-4c44-81e3-cc91b344403c"
}
}
}
I don't understand how to satisfy Thread is not marked for import.
I'll appreciate any help on how to succeed in this call. If not possible: any other way to send a message using the Graph API with App Registration token.
