Java之利用Socket获取网站内容

public void main(String[] args){

　　String host = "123.126.113.42";

　　int port = 80;

　　Socket s = new Socket(host, port);

　　BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(s.getOutputStream(), "UTF8")); 

　　BufferedReader br = new BufferedReader(new InputStreamReader(s.getInputStream()));

　　StringBuffer sb = new StringBuffer();

　　bw.write("GET / HTTP/1.1\r\n"); //get关键字必须大写

　　bw.write("Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8\r\n");

　　bw.write("Accept-Encoding:gzip,deflate,sdch\r\n");

　　bw.write("Accept-Language:zh-CN,zh;q=0.8\r\n");

　　bw.write("Connection: close\r\n");

　　bw.write("Host: www.sogou.com\r\n");

　　bw.write("User-agent: Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/31.0.1650.63 Safari/537.36 SE 2.X MetaSr 1.0\r\n");

　　bw.write("\r\n");

　　bw.flush(); //记得添加此操作

　　String lineContent = null;

　　while((lineContent = br.readLine()) != null){

　　　　System.out.println(lineContent);

　　}

　　br.close();

　　bw.close();

　　s.close();
