错误StatusCode：500，ReasonPhrase：Web API发布大文件中的“内部服务器错误”

Question

我尝试通过web api发布请求。我有一个包含图像字段的类。

我的代码：

public bool SendRequest(FaxBranchRecive faxBranchRecive)
{
     using (var client = new HttpClient())
     {
        int fileLength = faxBranchRecive.faxImage.Length;
        // fileLength = 3873396
        var response = client.PostAsJsonAsync("http://localhost:58000/api/FaxBranch/RecieveFax", faxBranchRecive).Result;
          if (response.IsSuccessStatusCode)
          {                                    
               return true;
          }
          else
          {
               return false;
          }

       }
}

发布时显示此错误：

{
    StatusCode: 500, 
    ReasonPhrase: 'Internal Server Error', 
    Version: 1.1, 
    Content: System.Net.Http.StreamContent, 
    Headers:

        Cache-Control: private

        Content-Length: 4549
        Content-Type: text/html; charset=utf-8
    }
}

是否需要在服务器中发布大文件的配置？
