使用的是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);
