我想给通过TCP连接字符串:发送和接收纯文本与TCP
TR220,2,A10000XX,3545.1743,5119.5794,001.0,1503,52:56:16,2012/09/13,0,0,0,0,0,V,000,0,0,0,,+989123456789,*
我使用此代码来发送的文字:
string uri = "http://localhost:1414";
String record = "TR220,2,A10000XX,3545.1743,5119.5794,001.0,1503,52:56:16,2012/09/13,0,0,0,0,0,V,000,0,0,0,,+989123456789,*";
HttpWebRequest request = (HttpWebRequest) WebRequest.Create(uri);
request.Method = "POST";
byte[] postBytes = GetBytes(record);
request.ContentType = "text/plain";
request.ContentLength = postBytes.Length;
Stream requestStream = request.GetRequestStream();
requestStream.Write(postBytes, 0, postBytes.Length);
和GetBytes方法:
private byte[] GetBytes(string str)
{
byte[] bytes = new byte[str.Length * sizeof(char)];
System.Buffer.BlockCopy(str.ToCharArray(), 0, bytes, 0, bytes.Length);
return bytes;
}
发送此请求后,在对方的应用程序,我得到th是字符串:
POST/HTTP/1.1\r\nContent-Type: text/plain\r\nHost: localhost:1414\r\nContent-Length: 212\r\nExpect: 100-continue\r\nConnection: Keep-Alive\r\n\r\n
使用的代码块:
tcpListener = new TcpListener(IPAddress.Any, 1414);
listenThread = new Thread(new ThreadStart(ListenForClients));
listenThread.Start();
和ListenForClients方法(一些代码为清楚起见省略):
NetworkStream clientStream = tcpClient.GetStream();
byte[] message = new byte[4096];
int bytesRead;
while (true)
{
bytesRead = 0;
try { bytesRead = clientStream.Read(message, 0, 4096); }
catch { break; }
ASCIIEncoding encoder = new ASCIIEncoding();
String data = encoder.GetString(message, 0, bytesRead);
MessageReceived(data);
}
我的问题是为什么发送和接收的字符串是不一样?
任何你需要在发送端使用HTTP的原因?你会碰到其他实际上是HTTP服务器的服务器吗? – Slugart 2013-05-04 07:29:44
我使用了完全相同的代码,并收到了标题和正文。 HTTPWebRequest类将始终添加HTTP标头,因为它是HTTP协议的一部分。 – Slugart 2013-05-04 07:40:37
