首先先要着重提一下，只要是做和项目有关的开发，首先按把环境中各个服务的版本保持一致，否则出些莫名其妙的错我，让你百爪挠心却不知哪里的问题。这里就要说下curl_setopt($ch, CURLOPT_POSTFIELDS, $array) 这个方法上传，在5.5之前是可以用的，5.5的时候已经设置为deprecated，会有下面的提示，5.6的时候已经被删除。所以5.6版本的可能不能直接使用网上的一些代码。
curl_setopt(): The usage of the @filename API for file uploading is deprecated. Please use the CURLFile class instead
因此这部分要根据版本判断下，修改为下面
/**
* CURL 上传文件
* @param $url 处理上传文件的url
* @param array $post_data post 传递的参数
* @param array $file_fields 上传文件的参数，支持多个文件上传
* @param int $timeout 请求超时时间
* @return array|bool
*/

$result = array('errno' => 0, 'errmsg' => '', 'result' => ''); $ch = curl_init();
//set various curl options first // set url to post to
curl_setopt($ch, CURLOPT_URL, $url); // return into a variable rather than displaying it
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); //set curl function timeout to $timeout
curl_setopt($ch, CURLOPT_TIMEOUT, $timeout);

// hack to make it working
