java 使用URL来读取网页内容

package network; import java.io.BufferedInputStream; import java.io.DataOutputStream; import java.io.InputStream; import java.io.InputStreamReader; import java.io.Reader; import java.net.HttpURLConnection; import java.net.URL; import java.net.URLEncoder; public class GetDataByURL { public static String cc(String leibie, String num) { StringBuffer temp = new StringBuffer(); try { System.out.println(leibie); System.out.println(num); String url = "http://www.baidu.com/jiaojing/ser.php"; HttpURLConnection uc = (HttpURLConnection)new URL(url). openConnection(); uc.setConnectTimeout(10000); uc.setDoOutput(true); uc.setRequestMethod("GET"); uc.setUseCaches(false); DataOutputStream out = new DataOutputStream(uc.getOutputStream()); // 要传的参数 String s = URLEncoder.encode("ra", "GB2312") + "=" + URLEncoder.encode(leibie, "GB2312"); s += "&" + URLEncoder.encode("keyword", "GB2312") + "=" + URLEncoder.encode(num, "GB2312"); // DataOutputStream.writeBytes将字符串中的16位的unicode字符以8位的字符形式写道流里面 out.writeBytes(s); out.flush(); out.close(); InputStream in = new BufferedInputStream(uc.getInputStream()); Reader rd = new InputStreamReader(in, "Gb2312"); int c = 0; while ((c = rd.read()) != -1) { temp.append((char) c); } System.out.println(temp.toString()); in.close(); } catch (Exception e) { e.printStackTrace(); } return temp.toString(); } public static void main(String[] a){ GetDataByURL.cc("1","吉H"); } }
