[Bug] 配置BASE_URL后直接返回html代码

[RogerProSelf]

Bug Description

在配置自部署的One-API的自定义BASE_URL后（形式如https://xxx.xxx.xxx:1234，非自签名SSL证书，端口外网访问正常），聊天界面直接返回HTML代码。

疑似是服务端侧访问导致的问题，因为在web ui中使用完全一样的自定义接口地址而不用默认的“api/openai”后就可以正常使用了。我看了之前别人的issue，似乎有提到在使用“api/openai”时是服务端侧访问，而自定义web ui中的接口地址时是客户端侧访问。

[Dean-YZG]

the cause of reponsing html page is the path is not exsit on finally target server deployed, please check your env vars, the splicing rule of a forward url is 'BASE_URL/v1/chat/completions'
