[Android实例] Android(安卓)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：

public class Client {
public static void main(String[] arg) {
Socket socket;
try {
socket = new Socket(“10.20.64.203″, 7001);
OutputStream os = socket.getOutputStream();
InputStream ins = socket.getInputStream();
String data= getXmlString();
StringBuffer sb = new StringBuffer();
sb.append(“POST /service HTTP/1.1\r\n”);// 注意\r\n为回车换行
sb.append(“Accept-Language: zh-cn\r\n”);
sb.append(“Connection: Keep-Alive\r\n”);
sb.append(“Host:localhost\r\n”);
sb.append(“Content-Length:11\r\n”);
sb.append(“\r\n”);
sb.append(“data=abc\r\n”);
sb.append(“\r\n”);
// 接收Web服务器返回HTTP响应包
os.write(sb.toString().getBytes());
os.flush();
byte[] b = new byte[1000];
ins.read(b); //读取http头
InputStreamReader ireader = new InputStreamReader(ins);
java.io.BufferedReader reader = new java.io.BufferedReader(ireader);
String s = reader.readLine(); //读取内容
System.out.println(“response:”+s);
System.out.println(reader.readLine());
System.out.println(reader.readLine());
System.out.println(reader.readLine());
System.out.println(reader.readLine());
System.out.println(reader.readLine());
System.out.println(reader.readLine());
} catch (UnknownHostException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
