Android利用HttpURLConnection发送参数及获得页面内容

代码如下，虽说很简单，但可以做很多事情。

package com.FatDiary.webservice;
import java.io.InputStream;
import java.net.HttpURLConnection;
import java.net.URL;

import org.apache.http.HttpStatus;

import android.util.Log;
public class TestWebService {

	public static String getReturnWord() {
		
		String rtn = "";
		
		URL url = null;
		HttpURLConnection httpConnection = null;
		InputStream in = null;
		
		try{
			
			url = new URL("http://192.168.1.100:8085/");
			httpConnection = (HttpURLConnection) url.openConnection();
			
			httpConnection.setConnectTimeout(5*1000);
			httpConnection.setDoOutput(true);
			
			String param = "username1=pijing&username2=卧龙居";
			byte[] out = param.getBytes();
			
			httpConnection.getOutputStream().write(out);
			httpConnection.getOutputStream().flush();
			
			byte[] buffer = new byte[1024];
			int index = -1;
			in = httpConnection.getInputStream();
			
			while((index=in.read(buffer,0,1024))!=-1){
				
				rtn += new String(buffer,0,index);
			}
			
		}catch(Exception ex){
			
			Log.i("info",ex.getMessage());
			rtn = ex.getMessage();
		}
		
		return rtn;
	}
}
