通过套接字连接tomcat
[英]Connect tomcat through socket
问题描述
I have been trying to communicate to tomcat using socket. 
我一直在尝试使用套接字与tomcat通信。 I am forming the HTTP message and writing that to the outputStream. 我正在形成HTTP消息并将其写入outputStream。 The connection gets established successfully but i am not receiving any response. 连接成功建立，但是我没有收到任何响应。 When i am trying to connect through telnet with the same message able to get the response. 当我尝试通过telnet连接时，同一条消息能够获得响应。 Please find the code snippet below and point what i am missing. 请找到下面的代码片段，并指出我所缺少的内容。
String text1 = text.getText();
String text2 = text_1.getText();
String address = combo.getText();
System.out.println("Text1 =" + text1 + " Text2 = " + text2 + " Address = "+address);
try{
StringBuilder builder = new StringBuilder();
Socket socket = new Socket("localhost", 8082);
DataOutputStream outToServer = new DataOutputStream(socket.getOutputStream());
BufferedReader inFromServer = new BufferedReader(new InputStreamReader(socket.getInputStream()));
//U need to post actual HTTP MESSAGE HERE
StringBuilder requestBuilder = new StringBuilder();
requestBuilder.append("GET").append(SPACE).append(FORWARD_SLASH).append("SayHello").append(FORWARD_SLASH).append("SayHello").append("?")
.append("text1=").append(text1).append("&text2=").append(text2).append(NEWLINE)/*.append(SPACE).append("HTTP/1.1").append(NEWLINE)
.append("accept").append(COLON).append(SPACE).append("text/plain;").append(SPACE).append("text/html").append(NEWLINE)
.append("accept-language").append(COLON).append("en-US").append(NEWLINE)
.append("connection").append(COLON).append("keep-alive").append(NEWLINE)
.append("host").append(COLON).append("localhost").append(NEWLINE)
.append("user-agent").append(COLON).append("MyUCBrowser").append(NEWLINE)
.append("content-length").append(COLON).append("0").append(NEWLINE)
.append("connection-type").append(COLON).append("text/plain").append(NEWLINE)*/;
/*box.setMessage(requestBuilder.toString());
box.open();*/
System.out.println(requestBuilder.toString());
outToServer.writeUTF(requestBuilder.toString());
String tempResp;
while ((tempResp = inFromServer.readLine()) != null) {
builder.append(tempResp);
}
System.out.println(builder.toString().length() > 0 ? builder.toString() : "Anup Kalane!!!");
text_2.setText(builder.toString());
socket.close();
display.dispose();
}
catch (UnknownHostException ex) {
// TODO Auto-generated catch block
ex.printStackTrace();
} catch (IOException ex) {
// TODO Auto-generated catch block
ex.printStackTrace();
}
For the convenience also attaching the servlet...It's very basic one. 为了方便起见，还附加了servlet ...这是非常基本的一个。 I just created it for testing purpose. 我只是出于测试目的而创建它。
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
String text1 = request.getParameter("text1") != null ? request.getParameter("text1") : "NULL";
String text2 = request.getParameter("text2") != null ? request.getParameter("text2") : "NULL";
System.out.println("Hello");
PrintWriter writer = response.getWriter();
writer.write("<HTML><BODY><H1>HELLO\nText1 = "+text1+"\nText2 = "+text2+"</H1></BODY></HTML>");
writer.close();
}

You are using writeUTF() where you should be using write(), but why are you doing all this at all? 您在应该使用write（）的地方使用了writeUTF（），但是为什么要这么做呢？ Why aren't you using HttpURLConnection or an HTTP client of some sort? 为什么不使用HttpURLConnection或某种HTTP客户端？ Don't reinvent the wheel. 不要重新发明轮子。
