Android学习笔记(六)之post请求

下面用两种方法

第一种：

是类似于直接请求访问url

代码如下：

[java]
package com.jouhu.util;

import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.URL;
import java.net.URLConnection;
import java.util.concurrent.CountDownLatch;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;

public class AssignService {


    public static String getServiceName(String assignUrl){
        String name=null;
        try {
            URL url = new URL(assignUrl);
            URLConnection uc = url.openConnection();
            uc.setConnectTimeout(5000);
            uc.setReadTimeout(8000);
            InputStream in = uc.getInputStream();
            BufferedReader br = new BufferedReader(new InputStreamReader(in));
            name = br.readLine();
            br.close();
            in.close();
        } catch (Exception e) {
            e.printStackTrace();
            return null;
        }
        return name;
    }

    public static void main(String[] arg) throws InterruptedException{
        final String URL_ASSIGN = "http://192.168.1.192:8888/ServiceAssign/assignService.action";
        int num=500;
        final CountDownLatch begin = new CountDownLatch(1);
        final CountDownLatch end = new CountDownLatch(num);
        final ExecutorService exec = Executors.newFixedThreadPool(num);
        for (int index = 0; index < num; index++) {
            Runnable run = new Runnable() {
                public void run() {
                    try {
                        begin.await();
                        AssignService.getServiceName(URL_ASSIGN);
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    } finally {
                        end.countDown();
                    }
                }
            };
            exec.submit(run);
        }
        System.out.println("Start");
        begin.countDown();
        end.await();
        exec.shutdown();
        System.out.println("Over");
    }
}

第二种：

通过POST将本地数据发送给服务器,string参数表

    public String sendMsg(double x,double y,String address) {
        //URLEncoder.encode(address, "gbk")
        String re="";

        try{
            List<NameValuePair> datas = new ArrayList<NameValuePair>();
            datas.add(new BaseNameValuePair("x", ""+x));
            datas.add(new BaseNameValuePair("y", ""+y));
            datas.add(new BaseNameValuePair("address", ""+address));

            re=sendDataByPost(url, datas);
