不能远程访问的问题

[v5star]

感谢大佬编写这个程序，很有用，但是我在使用过程中发现一个的，比如：ovsyunlive10这个程序运行在192.168.0.2上，在192.168.0.2上访问是正常的，如：在本机（192.168.0.2）访问http://192.168.0.2:7701/play/demo.html 频画面都能出来，但是用在其他的机器（192.168.0.3）访问http://192.168.0.2:7701/play/demo.html就不行了，经过跟踪发现，这个http://192.168.0.2:7701/index/api/webrtc?app=webplay&type=play&stream=0.17760481352591806返回的数据里全是127.0.0.1的地址。返回值如下：

（因为非本机192.168.0.3上没有装这个服务器，这个也不可能每个客户端都装一个这个服务），导致不能访问，麻烦大佬改一下也返回exthost的值。谢谢！也可能是其他错误原因。如：/index/api/ovplayer，这个接口后返回：{ "code" : -1, "msg" : "SETUP:500 Internal Server Error" } 具体错误或不显示视频画面的原因是什么，麻烦修改一下。感谢大佬~！！！
