从 NetworkStream 读取字节(挂起)
我正在尝试学习网络基础知识,并且我已经从 构建了一个回显服务器这个教程。我用 telnet 检查了服务器,它工作得很好。
现在,当我使用互联网上的许多客户端示例中的一些时:
// Create a TcpClient.
// Note, for this client to work you need to have a TcpServer
// connected to the same address as specified by the server, port
// combination.
TcpClient client = new TcpClient(server, port);
// Translate the passed message into ASCII and store it as a Byte array.
Byte[] data = System.Text.Encoding.ASCII.GetBytes(message);
// Get a client stream for reading and writing.
NetworkStream stream = client.GetStream();
// Send the message to the connected TcpServer.
stream.Write(data, 0, data.Length);
Console.WriteLine("Sent: {0}", message);
// Receive the TcpServer.response.
// Buffer to store the response bytes.
data = new Byte[256];
// String to store the response ASCII representation.
String responseData = String.Empty;
// Read the first batch of the TcpServer response bytes.
Int32 bytes = stream.Read(data, 0, data.Length);
responseData = System.Text.Encoding.ASCII.GetString(data, 0, bytes);
Console.WriteLine("Received: {0}", responseData);
// Close everything.
stream.Close();
client.Close();
它运行得不太好。如果我评论stream.Read行,一切都会完美(预计我无法阅读)。我还尝试使用异步回调方法以类似的方式进行读取。然后它只有在我终止程序后才起作用(服务器处理请求)
我怀疑我从流中读取的方式导致了这个块,但我太无能了,无法理解我做错了什么。
I'm trying to learn the basics of networking and I've built an echo server from this tutorial. I checked the server with telnet and it works perfect.
Now when I'm using some of the many client samples on the Internet:
// Create a TcpClient.
// Note, for this client to work you need to have a TcpServer
// connected to the same address as specified by the server, port
// combination.
TcpClient client = new TcpClient(server, port);
// Translate the passed message into ASCII and store it as a Byte array.
Byte[] data = System.Text.Encoding.ASCII.GetBytes(message);
// Get a client stream for reading and writing.
NetworkStream stream = client.GetStream();
// Send the message to the connected TcpServer.
stream.Write(data, 0, data.Length);
Console.WriteLine("Sent: {0}", message);
// Receive the TcpServer.response.
// Buffer to store the response bytes.
data = new Byte[256];
// String to store the response ASCII representation.
String responseData = String.Empty;
// Read the first batch of the TcpServer response bytes.
Int32 bytes = stream.Read(data, 0, data.Length);
responseData = System.Text.Encoding.ASCII.GetString(data, 0, bytes);
Console.WriteLine("Received: {0}", responseData);
// Close everything.
stream.Close();
client.Close();
It doesn't work very well. If I will comment the stream.Read line, everything works perfect (expect I can't read). I was also trying to accomplish that in a similar way using asynchronous callback method for the read. and then it only works after I terminate the program (the server handles the request)
I suspect that the way I'm reading from the stream cause this block, but I'm too clueless to understand what I'm doing wrong.

您的服务器可能没有发送你任何数据。
编辑:
我测试了你的客户端,它工作得很好。你自己尝试一下,设置如下参数:
肯定是你的服务器有问题。

Your server propably isn't sending you any data.
Edit:
I tested your client and it works perfectly fine. Try it yourself and set the following parameters:
It's definitely your server which has the problem.
