关于PHP获取私有属性（调用阿里云sdk,返回带私有属性的对象）

调用阿里云的滑动验证功能的sdk，官方文档说是返回json数据，但是一打印发现反回的居然是带有私有属性的对象，如下所示：

HttpResponse Object  

(  

    [body:HttpResponse:private] => {  

        "RequestId":"A7847F5F-959A-442F-9D4F-D9A823857128","AssumedRoleUser":{"AssumedRoleId":"381320982304412425:704036879","Arn":"acs:ram::20411481:role/bfvideo/704036879"},  

        "Credentials":{"AccessKeySecret":"BDsQMcruMnuP9a1qDJYYGUCPorjwyhBTJ7bUrF7vLoua",

这是阿里云sdk接口的问题，你直接改动他的sdk,返回数据就是json格式了。改动此目录下，aliyun-openapi-php-sdk-masteraliyun-openapi-php-sdk-masteraliyun-php-sdk-coreHttp，的HttpHelper.php，大概37行，删除或者屏蔽curl_setopt($ch,
CURLOPT_RETURNTRANSFER, true);即可。然后直接return，json数据就直接就返回了，无需再print_r（$rsponse）.
