在Java下抓取网页上的图片并保存到本地文件夹中

技术实现：

import java.net.URL; 
 
import java.net.MalformedURLException; 
 
import java.io.IOException; 
 
import java.io.FileNotFoundException; 
 
import java.io.BufferedInputStream; 
 
import java.io.FileOutputStream; 
 
import java.io.File; 
 
实现代码： 
 
public class TestGetImageFromUrl { 
 
/** 
 
* @param args 
 
*/ 
 
public static void main(String[] args) { 
 
// TODO Auto-generated method stub 
 
String httpUrl = "http://www.a3gs.com/关于我们.files/image002.gif"; 
 
URL url; 
 
BufferedInputStream in; 
 
FileOutputStream file; 
 
try { 
 
System.out.println("获取网络图片"); 
 
String fileName = httpUrl.substring(httpUrl.lastIndexOf("/") + 1); 
 
String filePath = "C:\\"; 
 
url = new URL(httpUrl); 
 
in = new BufferedInputStream(url.openStream()); 
 
file = new FileOutputStream(new File(filePath + fileName)); 
 
int t; 
 
while ((t = in.read()) != -1) { 
 
file.write(t); 
 
} 
 
file.close(); 
 
in.close(); 
 
System.out.println("图片获取成功"); 
 
} catch (MalformedURLException e) { 
 
e.printStackTrace(); 
 
} catch (FileNotFoundException e) { 
 
e.printStackTrace(); 
 
} catch (IOException e) { 
 
e.printStackTrace(); 
 
} 
 
} 
 
}
