使用PHP的SoapClient处理认证过的https webservice是完全没有问题的。但是如果遇到一些不去认证https而是用自建的证书来做https的时候就会有问题，一般会报“Could not connect to host.”错误。
解决方式之一就是试SoapClient忽略https的ssl认证，直接跳过认证的环节，直接贴代码吧
$context = stream_context_create( array ( 'ssl' => array ( 'verify_peer' => false, 'allow_self_signed' => true ),));$options['stream_context'] = $context;$client = new SoapClient($url, $options);
verify_peer：指定是否验证ssl，默认为true
allow_self_signed：是否允许自建证书的https服务，默认为false
贴上官方的文档：http://php.net/manual/en/context.ssl.php
