获取EOF例外通过https电话 [英] Getting EOF exception over https call

问题描述

我的code使HTTPS请求。这是我的code

  HttpWebRequest的要求=（HttpWebRequest的）WebRequest.Create（的uploadURL）;
            request.Method =POST;
            request.KeepAlive = FALSE;
            request.Credentials =新的NetworkCredential（用户ID，testpwd）;

            POSTDATA =＆LT;根＆GT;＆LT; /根＆gt;中;
            request.ContentType =应用/的X WWW的形式urlen codeD;

            byte []的postDataBytes = Encoding.UTF8.GetBytes（POSTDATA）;
            request.ContentLength = postDataBytes.Length;

            流requestStream = request.GetRequestStream（）;
            requestStream.Write（postDataBytes，0，postDataBytes.Length）;
            requestStream.Close（）;

            使用（HttpWebResponse响应=（HttpWebResponse）request.GetResponse（））
            {
                StreamReader的responseReader =新的StreamReader（response.GetResponseStream（），Encoding.UTF8）;
                VAR的结果= responseReader.ReadToEnd（）;
                responseReader.Close（）;
                Console.WriteLine（结果）;
            }
 

这code的运行良好，但以下情况例外突然投掷

  System.Net.WebException
 

     

异常消息是：   基础连接已关闭：上一个发送发生意外的错误

堆栈跟踪：    在System.Net.HttpWebRequest.GetRequestStream（TransportContext＆安培;上下文）    在System.Net.HttpWebRequest.GetRequestStream（）    在CustomerProcessor.Delivery.Deliver（字符串内容的Int32产品分类，标识字符串，字符串xsltFile）

该异常有一个内部异常： 发生异常： System.IO.IOException 异常消息为： 接收从传输流意想不到的EOF或0字节。

堆栈跟踪：    在System.Net.FixedSizeReader.ReadPacket（字节[]缓冲区的Int32偏移的Int32计数）    在System.Net.Security.SslState.StartReadFrame（字节[]缓冲区的Int32的ReadBytes，AsyncProtocolRequest的AsyncRequest）    在System.Net.Security.SslState.StartReceiveBlob（字节[]缓冲区，AsyncProtocolRequest的AsyncRequest）    在System.Net.Security.SslState.CheckCompletionBeforeNextReceive（ProtocolToken消息，AsyncProtocolRequest的AsyncRequest）    在System.Net.Security.SslState.StartSendBlob（字节[]来电，的Int32算，As​​yncProtocolRequest的AsyncRequest）    在System.Net.Security.SslState.ForceAuthentication（布尔receiveFirst，字节[]缓冲区，AsyncProtocolRequest的AsyncRequest）    在System.Net.Security.SslState.ProcessAuthentication（LazyAsyncResult lazyResult）    在System.Net.TlsStream.CallProcessAuthentication（对象状态）    在System.Threading.ExecutionContext.runTry code（对象USERDATA）    在System.Runtime.CompilerServices.RuntimeHelpers.Execute codeWithGuaranteedCleanup（试行code code，清理code撤销code，对象USERDATA）    在System.Threading.ExecutionContext.RunInternal（ExecutionContext中的ExecutionContext，ContextCallback回调，对象的状态）    在System.Threading.ExecutionContext.Run（ExecutionContext中的ExecutionContext，ContextCallback回调，对象的状态）    在System.Net.TlsStream.ProcessAuthentication（LazyAsyncResult结果）    在System.Net.TlsStream.Write（字节[]缓冲区的Int32偏移的Int32大小）    在System.Net.PooledStream.Write（字节[]缓冲区的Int32偏移的Int32大小）    在System.Net.ConnectStream.WriteHeaders（布尔异步）

有没有机会看到这可能是这个问题的原因是什么？

解决方案

添加此调用之前请求帮助我：

  ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3;
 

所以，如果你使用的是HTTPS试图更改默认SecurityProtocol。

My code making https request. This is my code

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(UploadUrl);
            request.Method = "POST";
            request.KeepAlive = false;
            request.Credentials = new NetworkCredential(userid, testpwd);

            postData = "<root></root>";
            request.ContentType = "application/x-www-form-urlencoded";

            byte[] postDataBytes = Encoding.UTF8.GetBytes(postData);
            request.ContentLength = postDataBytes.Length;

            Stream requestStream = request.GetRequestStream();
            requestStream.Write(postDataBytes, 0, postDataBytes.Length);
            requestStream.Close();

            using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
            {
                StreamReader responseReader = new StreamReader(response.GetResponseStream(), Encoding.UTF8);
                var result = responseReader.ReadToEnd();
                responseReader.Close();
                Console.WriteLine(result);
            }

This code was running good but all of a sudden throwing following exception

System.Net.WebException

The exception message is: The underlying connection was closed: An unexpected error occurred on a send.

Stack Trace: at System.Net.HttpWebRequest.GetRequestStream(TransportContext& context) at System.Net.HttpWebRequest.GetRequestStream() at CustomerProcessor.Delivery.Deliver(String content, Int32 productCategory, String identifier, String xsltFile)

The Exception has an inner exception: An Exception occurred: System.IO.IOException The exception message is: Received an unexpected EOF or 0 bytes from the transport stream.

Is there any chance to see what could be the cause of this issue?

解决方案

Adding this call before request helped me:

ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3;

So if you are using https try to change the default SecurityProtocol.
