使用图表 API 错误添加 MS Teams 网站选项卡

Add MS Teams website tab using graph API error

上下文:

我正在尝试向 MS Teams 中的现有频道添加一个新的网站选项卡,然后获取新创建的选项卡的 ID。

问题:

我可以创建新选项卡,但我从图表中收到 "BadRequest" 异常:

消息:值不能为空。参数名称:entity

有趣的是,该选项卡是在正确的团队和频道中的 MS Teams 中创建并显示的,但我无法以任何方式获取它的 ID。

我的代码:

var tab = await _graphClient.Teams[teamId].Channels[channelId].Tabs.Request().WithMaxRetry(3).AddAsync(
    new TeamsTab
    {
        DisplayName = "New Tab",
        AdditionalData = new Dictionary<string, object>
        {
            ["teamsApp@odata.bind"] =
                $"{_teamsFactory.GraphV1Endpoint}/appCatalogs/teamsApps/com.microsoft.teamspace.tab.web"
        },
        Configuration = new TeamsTabConfiguration
        {
            EntityId = null,
            WebsiteUrl = $"{_appUrl}/1",
            ContentUrl = $"{_appUrl}/1",
            RemoveUrl = null,

        }
    }
);

就像我在上面写的那样,此代码有效并创建了选项卡,但 GraphServiceClient 在分配 tab 变量之前抛出异常。

当我尝试在 Graph Explorer 中获取选项卡列表时

https://graph.microsoft.com/v1.0/teams/{teamid}/channels/{channelid}/tabs

我收到错误回复:

{
    "error": {
        "code": "InternalServerError",
        "message": "Failed to execute request.",
        "innerError": {
            "request-id": "a03654e8-37a7-4fbb-8052-6a1b11721234",
            "date": "2020-02-24T15:11:54"
        }
    }
}

我认为您可能需要为 "EntityId" 设置一个值 - 基本上只是一个字符串值,以唯一地 "name" 您的选项卡。它不是 "DisplayName",而是选项卡的字符串 "id"。

POST https://graph.microsoft.com/v1.0/teams/{id}/channels/{id}/tabs
{
  "displayName": "My Contoso Tab",
  "teamsApp@odata.bind" : "https://graph.microsoft.com/v1.0/appCatalogs/teamsApps/06805b9e-77e3-4b93-ac81-525eb87513b8",
  "configuration": {
    "entityId": "2DCA2E6C7A10415CAF6B8AB6661B3154",
    "contentUrl": "https://www.contoso.com/Orders/2DCA2E6C7A10415CAF6B8AB6661B3154/tabView",
    "websiteUrl": "https://www.contoso.com/Orders/2DCA2E6C7A10415CAF6B8AB6661B3154",
    "removeUrl": "https://www.contoso.com/Orders/2DCA2E6C7A10415CAF6B8AB6661B3154/uninstallTab"
  }
}

请看Add Tab to a channel using Graph API

编辑 1:能否请您检查一下您是否具有添加选项卡的适当权限?

Edit2:你能试试下面的代码吗?

GraphServiceClient graphClient = new GraphServiceClient( authProvider );

var teamsTab = new TeamsTab
{
    DisplayName = "WebsiteTab",
    AdditionalData = new Dictionary<string, object>()
    {
        {"teamsApp@odata.bind","https://graph.microsoft.com/v1.0/appCatalogs/teamsApps/com.microsoft.teamspace.tab.web"}
    },
    Configuration = new TeamsTabConfiguration
    {
        EntityId = null,
        ContentUrl = "https://docs.microsoft.com/en-us/microsoftteams/platform/resources/bot-v3/bots-context",
        RemoveUrl = null,
        WebsiteUrl = "https://docs.microsoft.com/en-us/microsoftteams/platform/resources/bot-v3/bots-context"
    }
};

await graphClient.Teams["TeamId"].Channels["ChannelId"].Tabs
    .Request()
    .AddAsync(teamsTab); 

最后我找到了 "solution",不过更好的名称是解决我的问题的方法。为了让它工作,我必须在 TeamsTabConfiguration 中将 ODataType 设置为 null。就这样。代码应如下所示:

var tab = await _graphClient.Teams[teamId].Channels[channelId].Tabs.Request().WithMaxRetry(3).AddAsync(
new TeamsTab
{
    DisplayName = TabTitle,
    ODataBind = $"{_teamsFactory.GraphV1Endpoint}/appCatalogs/teamsApps/com.microsoft.teamspace.tab.web",
    Configuration = new TeamsTabConfiguration
    {
        ODataType = null,
        EntityId = null,
        WebsiteUrl = $"{_appUrl}/1",
        ContentUrl = $"{_appUrl}/1",
        RemoveUrl = null
    }
});

就像我提到的那样,这只是一种解决方法。它在 GitHub (issue#598)

上标记为 "service bug"
