使用 Microsoft Graph 获取 MailBoxUsageDetails 时遇到 JsonReaderException

Question

我正在关注 https://docs.microsoft.com/en-us/graph/api/reportroot-getmailboxusagedetail?view=graph-rest-1.0&tabs=cs 中的 GetMailBoxUsageDetail 文档，但我收到 JsonReaderException。

完整的错误信息如下：JsonReaderException: Unexpected character encountered while parsing value: R. Path '', line 0, position 0.

我已确认我拥有适当的应用程序权限。我还使用了 Fiddler 并看到内容流正在返回到客户端应用程序，但是 Microsoft Graph API 似乎试图将内容反序列化为 Json 而不是。

    public IActionResult Index()
    {
        var report = GetMailBoxUsageDetailAsync().Result;
        return View();
    }


    public async Task<Report> GetMailBoxUsageDetailAsync(string period = "D7")
    {
        var graphClient = new GraphServiceClient(new MsalAuthenticationProvider());

        var report = await graphClient.Reports.GetMailboxUsageMailboxCounts(period)
            .Request()
            .GetAsync();

        return report;

     }

我期待流式内容返回以下 headers：报告刷新日期、用户主体名称、显示名称、已删除、删除日期、创建日期、最后 Activity 日期、项目计数、已用存储（字节）、发出警告配额（字节）、禁止发送配额（字节）、禁止 Send/Receive 配额（字节）、报告期间

确实，它似乎是 de-serializing 响应负载的错误，并影响 Mailbox usage reports

的所有端点

It could be reproduced at least in msgraph-sdk-dotnet version 1.15.0

在修复之前，可以考虑将以下解决方案作为备选方案：

//Construct and send a request 
var requestUrl = graphClient.Reports.GetMailboxUsageMailboxCounts("D7").Request().RequestUrl;
var request = new HttpRequestMessage(HttpMethod.Get, requestUrl);
await graphClient.AuthenticationProvider.AuthenticateRequestAsync(request);
var response = await graphClient.HttpProvider.SendAsync(request);

// Get the csv report data
var csvData = await response.Content.ReadAsStringAsync();
