c# - 我无法使用 c# 将文件上传到一个驱动器

Question

当我尝试使用 Microsoft Graph API 将文件上传到我的 OneDrive 时收到错误 400 Bad Request

• GetAccessToken 方法获取访问令牌

• 上传方法获取文件路径并将其上传到我的OneDrive帐户

  public class OneDrive
  {
  
   public void Upload(string filePath)
   {
  
       var token = GetAccessToken();
       var url = "https://graph.microsoft.com/v1.0/drive/root:/test/test.pdf:/content";
       PostRequest(url, token, filePath).Wait();
   }
   public string GetAccessToken()
   {
       var app = ConfidentialClientApplicationBuilder.Create("client id ")
             .WithClientSecret("client secret")
               .WithAuthority("https://login.microsoftonline.com/{tenant id}/v2.0")
             .Build();
       string[] scopes = new string[] { "https://graph.microsoft.com/.default" };
       try
       {
           var result = app.AcquireTokenForClient(scopes).ExecuteAsync().Result;
           Console.WriteLine(result.TenantId); 
           return result.AccessToken;
       }
       catch (MsalServiceException ex) when (ex.Message.Contains("AADSTS70011"))
       {
           Console.WriteLine(ex.Message);
           return null;
       }
   }
   public async Task PostRequest(string webApiUrl, string accessToken, string filePath)
   {
  
       HttpContent content = new StreamContent(new MemoryStream(File.ReadAllBytes(filePath)));
       HttpClient httpClient = new HttpClient();
       if (!string.IsNullOrEmpty(accessToken))
       {
           var defaultRequestHeaders = httpClient.DefaultRequestHeaders;
           httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/octet-stream"));
  
  
           defaultRequestHeaders.Authorization = new AuthenticationHeaderValue("bearer", accessToken);
  
           HttpResponseMessage response = await httpClient.PutAsync(webApiUrl, content);
           if (response.IsSuccessStatusCode)
               Console.WriteLine("File Successfuly Uploaded");
           else
               Console.WriteLine("Error Occur");
       }
   }
  }

删除此行后：

httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/octet-stream"));

您的代码非常适合我：

无需accpet在请求中设置标头。
