[Android实例] Android 实例SOCKET发送HTTP请求

       目的：客户端用socket连接web服务器发送ｈｔｔｐ请求，访问一个Servlet /service .并接收servlet的相应数据。
       我客户端代码可以访问到servlet可是servlet用request.getPrameter(“data”) 取不到请求内容.
       请指点：代码如下

java代码：

1. public class Client {
   
2. public static void main(String[] arg) {
   
3. Socket socket;
   
4. try {
   
5. socket = new Socket(“10.20.64.203″, 7001);
   
6. OutputStream os = socket.getOutputStream();
   
7. InputStream ins = socket.getInputStream();
   
8. String data= getXmlString();
   
9. StringBuffer sb = new StringBuffer();
   
10. sb.append(“POST /service HTTP/1.1\r\n”);// 注意\r\n为回车换行
    
11. sb.append(“Accept-Language: zh-cn\r\n”);
    
12. sb.append(“Connection: Keep-Alive\r\n”);
    
13. sb.append(“Host:localhost\r\n”);
    
14. sb.append(“Content-Length:11\r\n”);
    
15. sb.append(“\r\n”);
    
16. sb.append(“data=abc\r\n”);
    
17. sb.append(“\r\n”); 
    
18. 
    
19. // 接收Web服务器返回HTTP响应包
    
20. os.write(sb.toString().getBytes());
    
21. os.flush();
    
22. byte[] b = new byte[1000];
    
23. ins.read(b); //读取http头
    
24. InputStreamReader ireader = new InputStreamReader(ins);
    
25. java.io.BufferedReader reader = new java.io.BufferedReader(ireader);
    
26. String s = reader.readLine(); //读取内容
    
27. System.out.println(“response:”+s);
    
28. System.out.println(reader.readLine());
    
29. System.out.println(reader.readLine());
    
30. System.out.println(reader.readLine());
    
31. System.out.println(reader.readLine());
    
32. System.out.println(reader.readLine());
    
33. System.out.println(reader.readLine()); 
    
34. 
    
35. } catch (UnknownHostException e) {
    
36. e.printStackTrace();
    
37. } catch (IOException e) {
    
38. e.printStackTrace();
    
39. }
    
40. }
