I have been reading RSS-related content recently and want to use Java to implement an RSS subscription function. The code is relatively simple. You only need to read the channel xml and then use other formats to parse it. But note that the encoding format needs to be specified, otherwise the code will be garbled.
package com.cyz;
import java.io.BufferedInputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.Reader;
import java.net.URL;
import java.net.URLConnection;
public class TestURL {
public static void main(String[] args) throws IOException {
// test4();
// test3();
test2();
// test();
}
/**
* 获取URL指定的资源。
*
* @throws IOException
*/
public static void test4() throws IOException {
URL url = new URL("http://rss.mydrivers.com/rss.aspx?Tid=1");
// 获得此 URL 的内容。
Object obj = url.getContent();
System.out.println(obj.getClass().getName());
}
/**
* 获取URL指定的资源
*
* @throws IOException
*/
public static void test3() throws IOException {
URL url = new URL("http://rss.mydrivers.com/rss.aspx?Tid=1");
// 返回一个 URLConnection 对象，它表示到 URL 所引用的远程对象的连接。
URLConnection uc = url.openConnection();
// 打开的连接读取的输入流。
InputStream in = uc.getInputStream();
int c;
while ((c = in.read()) != -1)
System.out.print(c);
in.close();
}
/**
* 读取URL指定的网页内容
*
* @throws IOException
*/
public static void test2() throws IOException {
URL url = new URL("http://rss.mydrivers.com/rss.aspx?Tid=1");
// 打开到此 URL 的连接并返回一个用于从该连接读入的 InputStream。
Reader reader = new InputStreamReader(new BufferedInputStream(url.openStream()), "UTF-8");
int c;
while ((c = reader.read()) != -1) {
System.out.print((char) c);
}
reader.close();
}
/**
* 获取URL的输入流，并输出
*
* @throws IOException
*/
public static void test() throws IOException {
URL url = new URL("http://rss.mydrivers.com/rss.aspx?Tid=1");
// 打开到此 URL 的连接并返回一个用于从该连接读入的 InputStream。
InputStream in = url.openStream();
int c;
while ((c = in.read()) != -1)
System.out.print(c);
in.close();
}
}
