如何使用JAVA下载HTML页面？

解决方案

以下是代码：

  public static String savePage（final String URL）throws IOException {
 String line =，all =; 
 URL myUrl = null; 
 BufferedReader in = null; 
尝试{
 myUrl =新的URL（URL）; 
 in = new BufferedReader（new InputStreamReader（myUrl.openStream（）））; （（line = in.readLine（））！= null）{
 all + = line; 
 
 while 
} 
} finally {
 if（in！= null）{
 in.close（）; 
} 
} 
 
 return all; 
} 
  

现在你可以在while循环中处理一行一行。 p>

解决方案

Here is the code:

public static String savePage(final String URL) throws IOException {
    String line = "", all = "";
    URL myUrl = null;
    BufferedReader in = null;
    try {
        myUrl = new URL(URL);
        in = new BufferedReader(new InputStreamReader(myUrl.openStream()));

        while ((line = in.readLine()) != null) {
            all += line;
        }
    } finally {
        if (in != null) {
            in.close();
        }
    }

    return all;
}

Now you can process one line after one other in the while loop.
