Here is the code:

这是代码：

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.

现在您可以在 while 循环中一行一行地处理。

如果您可以使用Groovy编译为 java 字节码，您可以获取这样的页面：

String text = new URL("http://google.com").text
