[BUG] OpenAI接口自定义URL有点问题

[liangfengyuan]

Problem (one or two sentences)

我使用了API供应商 OpenAI ，添加了自定义URL，接口消息返回失败

Context (who is affected and when)

都可以测试。

Reproduction steps

我使用了API供应商 OpenAI ，添加了自定义URL，模型选择了gpt-5-codex/gpt-5-2025-08-07,在进行对话是，先发的这个消息是正常的。然后系统自己又生成了不知道什么。如图

后面的/v1 又继续叠加了一次 变成 /v1/v1了，造成返回失败。

Expected result

恢复 一个/v1

Actual result

目前是第一条消息正常。后面就是v1/v1重复了

I'm exploring a potential fix for the OpenAI custom URL duplication issue where /v1 is being appended twice. I'll investigate the URL construction logic and open a PR to share progress.

[roomote]

I've opened PR #8283 with a fix for the OpenAI custom URL duplication issue: #8283

The fix adds URL normalization logic to prevent /v1 from being duplicated when users provide custom OpenAI-compatible API URLs. The implementation:

• Ensures /v1 is present for OpenAI-compatible APIs but not duplicated
• Preserves Azure endpoints without modification
• Handles URLs with trailing slashes correctly
• Includes comprehensive test coverage

Note: Some CI tests are currently failing, but they appear to be unrelated to this change (the failures are in platform unit tests while the changes only affect URL normalization logic). The maintainers may need to investigate the CI issues separately.

用的openai还是openai兼容?
如果你用了像是newapi这种中转服务,要开启请求透传,可以更好支持responses端点

[liangfengyuan]

用的OpenAI

openai兼容问题更多。不支持responses

大概率中转的问题

另外codex模型现在有问题,我早上已经提交了issue,说是模型训练的问题,不遵循现在roocode的提示词指令

但是很奇怪的就是，我问的第一次是可以正常回复的。这里应该调用的是 v1/ 然后系统应该是总结吧，又调用了什么，就变成v1/v1了
