一、在Android用Get方式发送http请求，使用的是Java标准类，也比较简单。
主要分以下几步：
1.构造URL
URL url = new URL(String path);
2.设置连接
httpURLConnection = (HttpURLConnection) url.openConnection();
//超时时间
httpURLConnection.setConnectTimeout(3000);
//表示设置本次http请求使用GET方式
httpURLConnection.setRequestMethod("GET");
int responsecode = httpURLConnection.getResponseCode();//返回至为响应编号，如：HTTP_OK表示连接成功。
3.获取返回数据
if(responsecode == HttpURLConnection.HTTP_OK){
inputStream = httpURLConnection.getInputStream();
} //得到inputStream 就好办啦。
new InputStreamReader(inputStream,"utf-8")
4.关闭连接
void disconnect()
二、下面通过一个简单的Demo实现get方式的请求：
package com.http.get;
import java.io.BufferedReader;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.UnsupportedEncodingException;
import java.net.HttpURLConnection;
import java.net.MalformedURLException;
import java.net.URL;
public class HttpUtils {
private static String URL_PATH="http://www.baidu.com";
private static HttpURLConnection httpURLConnection = null;
public HttpUtils(){
}
public static void shuchu(){
InputStream inputStream = getInputStream();
String result;
try {
BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream,"utf-8"));
result = "";
String line = "";
try {
while((line = reader.readLine())!= null){
result = result+ line;
}
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
System.out.println(result);
httpURLConnection.disconnect();
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
/**
* 获取服务端的数据，以InputStream返回
* @return
*/
public static InputStream getInputStream(){
InputStream inputStream = null;
try {
URL url = new URL(URL_PATH);
if(url != null){
try {
httpURLConnection = (HttpURLConnection) url.openConnection();
//超时时间
httpURLConnection.setConnectTimeout(3000);
//表示设置本次http请求使用GET方式
httpURLConnection.setRequestMethod("GET");
int responsecode = httpURLConnection.getResponseCode();
if(responsecode == HttpURLConnection.HTTP_OK){
inputStream = httpURLConnection.getInputStream();
}
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return inputStream;
}
public static void main(String[] args){
//保存文件到本地
//saveImageToDisk();
shuchu();
}
}
//因为get方式是这ava标准类，直接写的java程序，不过都一样，android中也是一样的。。
简单的访问了百度，返回的就是百度搜索首页的源代码：图片一直上传不了。。。就不截图啦。
正确返回的就是你在网页单击右键有个查看源代码，返回的就是它，输出的也是它，自己可以去对比下一样不，是一样的。
