If you want to stream any webpage may it be a JSP or any other web page, you can use the method below.
如果您想流式传输任何网页，可能是 JSP 或任何其他网页，您可以使用以下方法。
import java.io.*;
import java.net.*;
public class c {
public String getHTML(String urlToRead) {
URL url;
HttpURLConnection conn;
BufferedReader rd;
String line;
String result = "";
try {
url = new URL(urlToRead);
conn = (HttpURLConnection) url.openConnection();
conn.setRequestMethod("GET");
rd = new BufferedReader(new InputStreamReader(conn.getInputStream()));
while ((line = rd.readLine()) != null) {
result += line;
}
rd.close();
} catch (Exception e) {
e.printStackTrace();
}
return result;
}
public static void main(String args[])
{
c c = new c();
System.out.println(c.getHTML(args[0]));
}
}
