GetResponse() 中的 500 内部服务器错误 [英] 500 internal server error at GetResponse()

问题描述

我有一个流量很大的 aspx 页面，根据每个用户的请求调用 Web 服务，如下所示.

I have a heavy traffic aspx page calling a web service upon every user`s request as follows.

string uri = "Path.asmx";
string soap = "soap xml string";

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uri);
request.Headers.Add("SOAPAction", ""http://xxxxxx"");
request.ContentType = "text/xml;charset="utf-8"";
request.Accept = "text/xml";
request.Method = "POST";

using (Stream stm = request.GetRequestStream())
{
    using (StreamWriter stmw = new StreamWriter(stm))
    {
        stmw.Write(soap);
    }
}
WebResponse response = request.GetResponse();
response.close();

一切正常，但有时我会收到以下错误.

Everything is working fine but sometimes I am getting the following error.

远程服务器返回错误:(500) 内部服务器错误.在 System.Net.HttpWebRequest.GetResponse()

有没有人知道这个错误，或者谁能告诉我我做错了什么.

Does anybody have any idea about this error or can anybody tell me if I am doing wrong.

推荐答案

最后，我使用以下代码摆脱了内部服务器错误消息.不确定是否有其他方法可以实现.

Finally I get rid of internal server error message with the following code. Not sure if there is another way to achieve it.

string uri = "Path.asmx";
string soap = "soap xml string";

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uri);
request.Headers.Add("SOAPAction", ""http://xxxxxx"");
request.ContentType = "text/xml;charset="utf-8"";
request.Accept = "text/xml";
request.Method = "POST";

using (Stream stm = request.GetRequestStream())
{
    using (StreamWriter stmw = new StreamWriter(stm))
    {
        stmw.Write(soap);
    }
}

using (WebResponse webResponse = request.GetResponse())
{
}
