使用此处的“Hello World”Microsoft Teams 应用程序示例：https://github.com/OfficeDev/msteams-samples-hello-world-csharp https://github.com/OfficeDev/msteams-samples-hello-world-csharp
在调用来自消息传递扩展的操作命令后，尝试获取个人 Microsoft Teams 1:1 聊天的参与者列表。具体来说，我需要其他参与者的电子邮件地址，而我是第一个参与者。
这是消息控制器的代码：
[BotAuthentication]
public class MessagesController : ApiController
{
[HttpPost]
public async Task<HttpResponseMessage> Post([FromBody] Activity activity)
{
using (var connector = new ConnectorClient(new Uri(activity.ServiceUrl)))
{
if (activity.IsComposeExtensionQuery())
{
// Invoke the command handler
var response = await MessageExtension.HandleMessageExtensionQuery(connector, activity).ConfigureAwait(false);
return response != null
? Request.CreateResponse<ComposeExtensionResponse>(response)
: new HttpResponseMessage(HttpStatusCode.OK);
}
else
{
await EchoBot.EchoMessage(connector, activity);
return new HttpResponseMessage(HttpStatusCode.Accepted);
}
}
}
}
代码来自MessageExtension.HandleMessageExtensionQuery如下：
public static async Task<ComposeExtensionResponse> HandleMessageExtensionQuery(ConnectorClient connector, Activity activity)
{
var query = activity.GetComposeExtensionQueryData();
if (query == null)
{
return null;
}
// Exception thrown here - error 403, there is no additional data except "Operation returned an invalid status code 'Forbidden'"
var members = await connector.Conversations.GetConversationMembersAsync(activity.Conversation.Id);
var handler = GetCommandHandler(query.CommandId); // Gets a handler based on the command, irrelevant for this question
if (handler == null)
{
return null;
}
return await handler.HandleCommand(query, members); // Should handle the command, but never comes here if we are in a 1:1 conversation
}
致电给GetConversationMembersAsync失败并显示以下消息：Operation returned an invalid status code 'Forbidden'如果该命令是从两个人之间 1:1 的个人对话中调用的。
如果从组通道调用，则呼叫不会失败。
如何获取1:1私人对话的参与者名单？我是否必须通过机器人对我的用户进行身份验证才能执行此操作，或者我是否必须授予我的机器人某些特定权限？我的帐户是否需要具有某些特定权限才能执行此操作？

编辑 2 - 尝试后，基于示例 51 - TeamsMessagingExtensionsAction
按照建议，我尝试了示例 51 名为“TeamsMessagingExtensionsAction” https://github.com/microsoft/BotBuilder-Samples/tree/master/samples/csharp_dotnetcore/51.teams-messaging-extensions-action代码是：
MicrosoftAppCredentials.TrustServiceUrl(turnContext.Activity.ServiceUrl);
var members = (await turnContext.TurnState.Get<IConnectorClient>().Conversations.GetConversationMembersAsync(
turnContext.Activity.Conversation.Id).ConfigureAwait(false)).ToList();
异常以及堆栈跟踪：

编辑 3 - 尝试使用示例 57
所以我开始了样本 57 名为“TeamsConversationBot” https://github.com/microsoft/BotBuilder-Samples/tree/master/samples/csharp_dotnetcore/57.teams-conversation-bot和 TLDR；在频道中有效，在私人对话中无效。
以下是执行的步骤：
注意：ngrok 已经使用命令启动ngrok http -host-header=rewrite 3978我现有的机器人注册已配置为侦听给定的 URL
- 更新了项目的 appsettings.json 配置，以使用 Bot Framework 注册中的 Microsoft 应用程序 ID 和应用程序密码。
- 使用所需的 GUID 编辑 TeamsAppManifest 中包含的 Manifest.json，将其与 PNG 图标一起压缩到 Manifest.zip 中，并使用“上传到 Teams App Studio”导入现有应用程序”，这产生了一个名为“TeamsConversationBot”的新应用程序
- 在 Teams App Studio 中，打开新应用程序进行编辑，转到“测试和分发”，点击“Install“ 进而 ”Add“在下一个屏幕上。
- 再次导航到上面的屏幕，但不是“Add“ 我选择了 ”添加到团队“从下拉菜单中，我将机器人添加到了我所拥有的团队的频道中。
- 在 Visual Studio 中，转到TeamsConversationsBot.cs并设置断点消息所有成员异步方法，在一行中写着
var members = await TeamsInfo.GetMembersAsync(turnContext, cancellationToken);
- 启动项目，转到我在 Teams 中的频道，发送“给所有会员留言” 对于我的机器人，等待上述断点被击中并观察到上述调用成功，即返回成员列表。到目前为止，一切都很好！
- 返回 Teams 应用程序生成器编辑我的“Teams 对话机器人”应用程序。
- 在清单编辑器中，转到“消息传递扩展”选项卡并设置我现有的机器人来侦听消息传递扩展调用。
- 添加了一个新的基于操作的命令，其中包含已定义的参数数量。给它一个 Id、命名一个参数并输入其他必填字段，这并不重要。对于“选择撰写扩展应该工作的上下文”，我选择了“命令盒" and "撰写框“，勾选”初始运行”并点击“Save".
- 使用“再次安装该应用程序测试和分发” -> “Install“ 进而 ”Add“ 按钮。
-
在Visual Studio中，添加以下方法TeamsConversationBot.cs:
protected override async Task<InvokeResponse> OnInvokeActivityAsync(ITurnContext<IInvokeActivity> turnContext, CancellationToken cancellationToken)
{
var connector = turnContext.TurnState.Get<IConnectorClient>();
var conversation = turnContext.Activity.Conversation;
var members = await connector.Conversations.GetConversationMembersAsync(conversation.Id, cancellationToken);
return await base.OnInvokeActivityAsync(turnContext, cancellationToken);
}
在行上设置一个断点var members = await connector.Conversations.GetConversationMembersAsync(conversation.Id, cancellationToken);并启动项目
- 进入频道，在撰写框下选择消息传递扩展并调用新添加的命令。这触发了上面的断点。执行一步并观察到
members变量包含频道的所有成员。所以这也有效！
- 进行我和其他团队成员之间的私人对话（我和他们之前都已互相发送消息，以确保对话不为空），选择撰写框下的消息扩展并调用新添加的命令。这再次触发了上述断点。执行了一步并bam!调用导致了未处理的异常
Microsoft.Bot.Schema.ErrorResponseException: Operation returned an invalid status code 'Forbidden'
