(500) 内部服务器错误 - 使用 api 发送 Web 请求时

我正在发送 Web 请求并收到内部服务器错误:500.

I am sending a web request and getting internal server error : 500.

我如何确定哪一方对出现此错误负责?我这边还是外部api那边?

How can i be sure what side is responsible for getting this error? My side or the external api side?

我在事件查看器中没有看到日志.

I didn`t see logs in my event viewer.

这是我的代码:

var request = WebRequest.Create("http://saas.appoxee.com/api/") as HttpWebRequest;
request.Method = WebRequestMethods.Http.Post;
request.ContentType = "application/json";

// Add the content to the request
string postDataJsonFormat = CreateExampleTagRequest();
byte[] byteArray = Encoding.UTF8.GetBytes(postDataJsonFormat);
request.ContentLength = byteArray.Length;

Stream dataStream = request.GetRequestStream();
dataStream.Write(byteArray, 0, byteArray.Length);
dataStream.Close();

// Getting and processing the response
var response = request.GetResponse() as HttpWebResponse;
