Teams移动端isNotificationOnly: true不生效，需修改manifest.json吗？

问题描述 #

已配置Teams Bot将isNotificationOnly设为true以禁用用户发送消息，该配置在PC端Teams正常生效，但移动端仍允许用户发送消息，询问是否需要对manifest.json进行额外修改。

当前Bot配置片段：

"bots": [
  {
    "botId": "11111111-1111-1111-1111-111111111111",
    "scopes": [
      "personal",
      "groupchat"
    ],
    "supportsFiles": false,
    "isNotificationOnly": true
  }
]

项目环境：

<TargetFramework>net6.0</TargetFramework>

完整manifest.json：

{
  "$schema": "https://developer.microsoft.com/json-schemas/teams/v1.11/MicrosoftTeams.schema.json",
  "manifestVersion": "1.11",
  "version": "1.1.0",
  "id": "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX",
  "packageName": "com.XXXX.teams.XXXXX.framework.XXXX",
  "developer": {
    "name": "XXXX",
    "websiteUrl": "https://XXXXX.com",
    "privacyUrl": "https://XXXXX.com/company/legal/privacy-policy",
    "termsOfUseUrl": "https://XXXXX.com/company/legal/privacy-policy"
  },
  "icons": {
    "color": "color.png",
    "outline": "outline.png"
  },
  "name": {
    "short": "XXXXX Bot ",
    "full": "XXXXX Bot"
  },
  "description": {
    "short": "Provide interactive automation between end user and Neurons Bots.",
    "full": "The XXXX bot for Microsoft Teams provides interactive capabilities between the end user and Ivanti Neurons Bots. Administrators now can solicit real-time responses from their users during the execution of a Bots workflow and use that input to deliver a more tailored experience to their end user."
  },
  "accentColor": "#FF1515",
  "bots": [
    {
      "botId": "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXx",
      "scopes": [
        "personal",
        "groupchat"
      ],
      "supportsFiles": false,
      "isNotificationOnly": true
    }
  ],
  "permissions": [
    "identity",
    "messageTeamMembers"
  ],
  "validDomains": [
    "token.botframework.com"
  ],
  "configurableProperties": [
    "name",
    "shortDescription",
    "longDescription",
    "smallImageUrl",
    "largeImageUrl",
    "accentColor",
    "developerUrl",
    "privacyUrl",
    "termsOfUseUrl"
  ]
}

解决建议 #

1. 升级manifest版本
   当前使用的manifest版本为v1.11，虽然isNotificationOnly从v1.8开始支持，但移动端对旧版本manifest的适配可能存在滞后。建议将manifest升级到最新稳定版本（如v1.16），同步更新schema链接为对应版本的地址，重新打包发布应用。

2. 更新Teams移动端版本
   旧版本Teams移动端可能未完全支持isNotificationOnly配置，需引导用户将Teams App更新到应用商店中的最新版本后再测试效果。

3. 清除缓存并重部署应用
   移动端可能缓存了旧的应用配置，修改manifest后需重新打包成.zip文件，上传到Teams管理中心完成更新；同时让用户清除Teams App缓存或重新安装应用，确保加载最新配置。

4. 代码层拦截兜底
   如果上述配置调整后仍未生效，可在Bot代码中添加消息拦截逻辑，当收到用户发送的消息时直接返回提示信息，示例C#代码：

   protected override async Task OnMessageActivityAsync(ITurnContext<IMessageActivity> turnContext, CancellationToken cancellationToken)
   {
       await turnContext.SendActivityAsync(MessageFactory.Text("此Bot仅用于推送通知，无法接收您的消息"), cancellationToken);
   }
