我們使用 net.URL 類的 URL() 構造函數來抓取網頁
代碼如下
import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.FileWriter;
import java.io.InputStreamReader;
import java.net.URL;
public class Main {
public static void main(String[] args)
throws Exception {
URL url = new URL("http://www.baidu.com");
BufferedReader reader = new BufferedReader
(new InputStreamReader(url.openStream()));
BufferedWriter writer = new BufferedWriter
(new FileWriter("test.html"));
String line;
while ((line = reader.readLine()) != null) {
System.out.println(line);
writer.write(line);
writer.newLine();
}
reader.close();
writer.close();
}
}
結果輸出
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"/> <meta http-equiv="X-UA-Compatible" content="IE=11,IE=10,IE=9,IE=8"/>……
