…的API格式，使用preview版本的api-version - 修复了Azure渠道无法正确处理responses请求的问题

Summary by CodeRabbit

• New Features
  • Added support for handling the "responses" relay mode in the Azure channel, enabling requests to use a dedicated endpoint for this mode.

[coderabbitai]

Walkthrough

A special case was added to the GetRequestURL method in the Azure channel adaptor to handle the "responses" relay mode. When this mode is detected, the method returns a fixed request URL for the responses endpoint, bypassing the usual URL construction logic. No public interfaces or error handling mechanisms were altered.

Poem

A hop and a skip, a relay anew,
For "responses" mode, we know what to do!
No more guessing, no more roam,
The URL is set—directly home.
Azure paths now neat and bright,
Rabbits code through day and night!

91-97: Hard-coded preview API version & redundant pre-processing

1. The string /openai/v1/responses?api-version=preview is hard-coded.
   • If Microsoft ships a non-preview or a new preview version, the adaptor will silently break.
   • Consider extracting the preview tag into a constant (e.g. constant2.AzureResponsesPreviewAPIVersion) or reuse info.ApiVersion when caller sets it explicitly.

2. The requestURL, task, and model_ scaffolding above is executed unconditionally, then discarded by this early-return. Moving the RelayModeResponses branch to the top of the Azure case (before those computations) avoids pointless work and keeps intent clearer.

 case common.ChannelTypeAzure:
+   // Fast-path for /responses endpoint – no deployment prefix required.
+   if info.RelayMode == constant.RelayModeResponses {
+       apiVersion := info.ApiVersion
+       if apiVersion == "" {
+           apiVersion = constant2.AzureResponsesPreviewAPIVersion // "preview"
+       }
+       requestURL := fmt.Sprintf("/openai/v1/responses?api-version=%s", apiVersion)
+       return relaycommon.GetFullRequestURL(info.BaseUrl, requestURL, info.ChannelType), nil
+   }
+
    apiVersion := info.ApiVersion
    ...
-   // 特殊处理 responses API
-   if info.RelayMode == constant.RelayModeResponses {
-       requestURL = fmt.Sprintf("/openai/v1/responses?api-version=preview")
-       return relaycommon.GetFullRequestURL(info.BaseUrl, requestURL, info.ChannelType), nil
-   }

This refactor keeps behaviour identical while improving maintainability and future-proofing.

  • I pushed a fix in commit <commit_id>, please review it.
  • Explain this complex logic.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai explain this code block.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and explain its main purpose.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

azure 的 responses api 直接配置了带有/v1/responses的地址，好像没有生效，该如何使用呢？或者在配置的时候需要有什么特殊的操作

不需要,正常对接az 渠道,就可以 使用 responses api请求了

[threadshare]

再麻烦问一句，我只看了 merged 的代码。看到是如果 baseUrl 中包含了 /v1/responses 的话会自动拼接完整的 responses api地址。然后我用 responses api 的方式来调用，gpt-4.1 正常返回，但是o3-pro的话显示 “Resource not found”， 实际我使用 curl 自己拼接请求o3-pro的调用是能正常返回的，您知道这可能是什么原因么？

你拼接的url 发出来看看呢

感谢 可能 azure 权限的问题导致 resource 找不到，但是 curl 能调用通，现在可以了。
