调用http接口

代码简单便捷，几步搞定，跟大家分享一下。

package cn.ins.Demo;

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;

public class SaleoutTest {
	public static void main(String[] args) throws Exception {
			URL url = new URL("");// 填写调用的地址
			
			HttpURLConnection conn=doConn(url);
			String message = "";// 填写需要传递的信息
			conn.getOutputStream().write(message.getBytes("utf-8"));
			// 查看返回的请求
			if(conn.getResponseCode()==200){
				System.out.println("OK");
			}else{
				System.out.println("notOK");
			}
			// 获取响应
			BufferedReader in=new BufferedReader(new InputStreamReader(conn.getInputStream(),"utf-8"));
			String line="";
			StringBuffer sb = new StringBuffer();
			while((line=in.readLine())!=null){
				sb.append(line);
			}
			System.out.println(sb.toString());
	}

	private static HttpURLConnection doConn(URL url) throws Exception {
		// 获得连接对象  
		HttpURLConnection conn = 
			(HttpURLConnection) url.openConnection();     
		// 设置属性  
		conn.setRequestMethod("POST");  
		
		// 设置输入流和输出流,都设置为true  
		conn.setDoOutput(true);  
		conn.setDoInput(true); 
		// 设置请求的内容类型
		conn.setRequestProperty(
				"Content-type", 
		"application/x-www-form-urlencoded");
		return conn;
	}
