跳过https认证工具类

开发中时常需要在内部去访问接口，有些是https 已操作就是报错认证错误

1
javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

第一种解决方案是去配置证书。。

这个我在天气接口就这么做过，毕竟是一直使用一个地址的接口，加入证书没啥毛病。

这下弄了个rss 地址可不统一，

所以用第二种方式 去跳过认证
