从网页中获取网页的源代码

package com.android.service; import java.io.InputStream; import java.net.HttpURLConnection; import java.net.URL; import com.android.tools.StreamTool; public class HtmlService { /** * 得到从网页上获得网页源码字符串 * @param path * @return * @throws Exception */ public static String getHtml(String path) throws Exception { URL url = new URL(path); HttpURLConnection conn = (HttpURLConnection)url.openConnection(); // 打开一个网络连接 conn.setRequestMethod("GET"); conn.setConnectTimeout(5 * 1000); InputStream inStream = conn.getInputStream(); // 通过输入流获取html数据 byte[] data = StreamTool.readInputStream(inStream); // 得到html的二进制数据 String html = new String(data, "utf-8"); // 转换字符编码 return html; } }
