Question

您好，我试图访问Office 365 Sharepoint中的某些列表。我已经设法通过较新的api调用MyFiles列表，但我相信你需要使用其他API来调用其他列表。我使用相同的访问令牌来访问文件，但下面的代码会引发未经授权的错误。有没有人对我出错的地方有任何建议？

string requestUrl = "https://mycompany.sharepoint.com/_api/Web/Lists/";
HttpClient client = new HttpClient();
HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Get, requestUrl);
request.Headers.Accept.Add(new MediaTypeWithQualityHeaderValue("application/atom+xml"));
request.Headers.Authorization = new AuthenticationHeaderValue("Bearer", accessToken);
HttpResponseMessage response = await client.SendAsync(request);

if (response.IsSuccessStatusCode)
{
      string responseString = await response.Content.ReadAsStringAsync();
      return responseString;
}
return "Problem";

发生身份验证错误时，Office 365将返回包含X-Ms-diagnostics header的HTTP响应：

标题具有以下格式：

X-Ms-diagnostics = errorId ";" source ";" reason ";" fault

source和reason属性包含有关错误的详细信息，例如：

Reason: Token contains invalid signature.

Source: invalid_client

以下示例演示了如何检索响应错误详细信息：

using(var client = new HttpClient())
{
    var request = new HttpRequestMessage(HttpMethod.Get, endpointUrl);
    request.Headers.Accept.Add(new MediaTypeWithQualityHeaderValue("application/atom+xml"));
    request.Headers.Authorization = new AuthenticationHeaderValue("Bearer", accessToken);
    var response = client.SendAsync(request).Result;

    if (!response.IsSuccessStatusCode && response.StatusCode == HttpStatusCode.Unauthorized)
    {
       var diagnosticsValue = response.Headers.GetValues("x-ms-diagnostics").FirstOrDefault(); 

    }
}
