HtmlRequest类的内容:
package com.capinfotech.net;
import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.net.HttpURLConnection;
import java.net.URL;
public class HtmlRequest {
public static void main(String[] args) throws IOException {
URL url = new URL("http://www.163.com/");
HttpURLConnection conn = (HttpURLConnection)url.openConnection();
InputStream inputStream = conn.getInputStream(); //通过输入流获得网站数据
byte[] getData = readInputStream(inputStream); //获得网站的二进制数据
String data = new String(getData, "gb2312");
System.out.println(data);
}
public static byte[] readInputStream(InputStream inputStream) throws IOException {
byte[] buffer = new byte[1024];
int len = 0;
ByteArrayOutputStream bos = new ByteArrayOutputStream();
while((len = inputStream.read(buffer)) != -1) {
bos.write(buffer, 0, len);
}
bos.close();
return bos.toByteArray();
}
}
这样就能获得http://www.163.com的内容,在控制台会打印输出
