OpenAI 翻译自定义接口适配问题，接口路径中如果带前缀会替换错误

[kongwu-]

Describe the bug 使用的是 openrouter 这个模型网关，接口字段里配置的是： https://openrouter.ai/api/

验证时请求的时： https://openrouter.ai/v1/chat/completions

但我实际的地址应该是前面还有个 api/ 的： https://openrouter.ai/api/v1/chat/completions

配置截图：

版本： 1.2.4.919

建议的解决方案： 可以参考其他家的方式，这个字段不做任何处理，改个逻辑为：接口路径，或者baseUrl之类的东西，这样就可以直接配置：

1. https://openrouter.ai/api/
2. https://xxxx.ai/乱七八糟的前缀/

或者可以参考下Bob的设计，也比较灵活

适配带与不带path的两种uri，对于你的情况你直接填写完整的uri就可以了

https://openrouter.ai/api/v1/chat/completions

// 只有当用户输入uri的path部分不以/v1/chat/completions或者/v1/completions结尾才修改path
if (!uriBuilder.Path.EndsWith("/v1/chat/completions") && !uriBuilder.Path.EndsWith("/v1/completions"))
    uriBuilder.Path = "/v1/chat/completions";

感谢作者配置完整URL可以解决，但还有另外一个小问题，导致openrouter里的openai无效：

openrouter 返回的 event stream body有一些自己的标记，导致解析失败了：

这样就不是服务适配的问题了，而是你所使用的服务提供商api并不于openai官方一致导致的，可以给他们反馈一下这个问题。
