String url="http://120.132.0.117:8080/yun90/article/GetRelatedArticles";

代码

package com.basic;

public class Parse02 {
    public static void main(String[] args) {
        String post = "POST http://120.132.0.117:8080/yun90/article/GetRelatedArticles HTTP/1.1\r\nHost: blog.csdn.net\r\nConnection: keep-alive\r\n\r\npageindex=2&articleId=23462041";
        String url="http://120.132.0.117:8080/yun90/article/GetRelatedArticles";
        
        /*
         * 一、按位置切割请求协议：即http
         */
        int index=url.indexOf("://");
        String scheme=url.substring(0,index);
        System.out.println("scheme="+scheme);

         * 二、解析ip
         */

        System.out.println("new url="+url+"\r\n");

        /*
         * 四、解析应用名和资源路径
         */
