如何从Java获取网页的源代码
我只想从Java检索任何网页的源代码。 到目前为止我找到了很多解决方案，但我找不到适用于以下所有链接的代码：

- http://www.fotomac.com.tr/Yazarlar/Olcay%20%C3%87ak%C4%B1r/2011/11/23/hesap-makinesi
- http://www.sabah.com.tr/Gundem/2011/12/23/basbakan-konferansta-konusuyor#
对我来说，主要问题是某些代码检索网页源代码，但缺少代码。 例如，下面的代码不适用于第一个链接。
InputStream is = fURL.openStream(); //fURL can be one of the links above BufferedReader buffer = null; buffer = new BufferedReader(new InputStreamReader(is, "iso-8859-9")); int byteRead; while ((byteRead = buffer.read()) != -1) { builder.append((char) byteRead); } buffer.close(); System.out.println(builder.toString()); 使用添加的请求属性尝试以下代码：
import java.io.BufferedReader; import java.io.IOException; import java.io.InputStream; import java.io.InputStreamReader; import java.net.URL; import java.net.URLConnection; public class SocketConnection { public static String getURLSource(String url) throws IOException { URL urlObject = new URL(url); URLConnection urlConnection = urlObject.openConnection(); urlConnection.setRequestProperty("User-Agent", "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.11 (KHTML, like Gecko) Chrome/23.0.1271.95 Safari/537.11"); return toString(urlConnection.getInputStream()); } private static String toString(InputStream inputStream) throws IOException { try (BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream, "UTF-8"))) { String inputLine; StringBuilder stringBuilder = new StringBuilder(); while ((inputLine = bufferedReader.readLine()) != null) { stringBuilder.append(inputLine); } return stringBuilder.toString(); } } }
我确信您在过去的两年中找到了解决方案，但以下是适用于您所请求站点的解决方案
