java 简单的http连接使用

milk_36

前些日子突然要使用http连接调用接口,因为之前没有写过这种连接的代码然后在网上搜寻了很久.在网上也有很多仁兄都有帖子.下面是很简单的get连接:
private static URL url;private static HttpURLConnection url_con;public static int send_url(String param) {                        url = new URL(path + "?" + param);//格式http://192.168.1.11:8080/work?name=aa&password=11url_con = (HttpURLConnection) url.openConnection();url_con.setRequestMethod("GET");code = url_con.getResponseCode();if (code == url_con.HTTP_OK) {InputStream in = url_con.getInputStream();DataInputStream dis = new DataInputStream(in);Sysout.out.println(dis.readUTF());} else {Sysout.out.println("msg:"+code);}} 在有些代码例子中,建立http连接会这样写:
       URL U = new URL(urlName);　　 URLConnection connection = U.openConnection();　　 connection.connect(); 关键是在URL.openConnection();
