该问题的解决办法 1、在请求前需要将证书导入，不推荐 2、绕开安全协议处理
下面的代码时一段http请求并且绕开安全协议。可直接使用
/**
*
* @param url 需要请求的网关路径
* @param sendData 请求时需要传入的参数
* @param urlencode url的编码格式
* @param connTimeOut 链接超时时间
* @param readTimeOut 读取超时时间
* @param contentType 请求头部 固定输入"application/x-www-form-urlencoded;charset="+urlencode
* @param header 输入null
* @return
