使用okhttp请求第三方https接口返回异常

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

意思就是非安全的调用，java不认识这个接口证书。java security仓库中没有这个第三方站点的SSL证书，调用失败。

这里为了简单,我直接忽略ssl证书认证,代码如下
