这是一个网站的官方API调用的例子，可是我运行该代码后出现“Fatal error: Uncaught exception 'Exception' with message 'Could not get reply: Could not resolve host: mtgox.com; Host not found' in C:\xampp\htdocs\bit\mtgox_offical_exam.php:31 Stack trace: #0 C:\xampp\htdocs\bit\mtgox_offical_exam.php(38): mtgox_query('0/info.php') #1 {main} thrown in C:\xampp\htdocs\bit\mtgox_offical_exam.php on line 31”的页面提示，请教大侠明示错误出在哪里怎么解决。我的XAMPP环境openssl和CURL都已开启。<?php function mtgox_query($path, array $req = array()) {

通过异常消息可知错误是域名解析的问题，这个网站在我这是正常的，可能是你的运行机器断网了，或者是DNS的问题
