用的是httpclient 3.1, 使用"httpclient"4的写法相对简单点,百度:httpclient https post 当不需要使用任何证书访问https网页时,只需配置信任任何证书 其中信任任何证书的类MySSLProtocolSocketFactory 主要代码: HttpClient client = new HttpClient(); Protocol myhttps = new Protocol("https", new MySSLProtocolSocketFactory(), 443); Protocol.registerProtocol("https", myhttps); PostMethod method = new PostMethod(url); package com.urthinker.wxyh.util; import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader;
