Summary of Changes

Hello @mci77777, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request significantly enhances the authentication token routing capabilities by introducing a two-tiered selection process. It first allows for a configurable preference to determine which group of tokens (provider-based or credential-based) should be considered. Subsequently, within the chosen group, individual tokens can now be assigned a priority, enabling fine-grained control over their selection order. This provides greater flexibility and control for administrators in managing and optimizing token usage, ensuring that critical or preferred tokens are utilized effectively.

Highlights

  • Routing Preference Introduction: Introduced a new routing 'preference' configuration, allowing administrators to specify whether to prioritize 'provider-first' or 'credential-first' when selecting authentication tokens.
  • Authentication Token Priority: Implemented a 'priority' system for individual authentication tokens, enabling tokens to be assigned a priority level (fallback, default, preferred) to influence their selection order within a chosen routing group.
  • New API Endpoints: Added new API endpoints for managing both the global routing preference and the priority of individual authentication files, providing programmatic control over these new features.
  • Configuration Refactoring and Migration: Refactored the internal selector logic and configuration handling to support the new preference and priority mechanisms, including a migration path for legacy routing strategy configurations to ensure backward compatibility.

Code Review

此拉取请求为请求路由到不同凭证引入了一套复杂的优先级和偏好系统。它将路由配置重构为 preferencestrategy 组件,并确保了与旧配置的向后兼容性。此外,还添加了用于管理认证文件优先级和路由偏好的新 API 端点。这些更改实现得很好,并为新逻辑添加了全面的测试。我的主要反馈是解决一些代码重复问题以提高可维护性。总的来说,这是对路由功能的一次坚实的增强。

这个 parsePriorityValue 函数在 sdk/auth/filestore.go 中有重复。为了避免代码重复并提高可维护性,应将此逻辑集中化。可以考虑将此函数移动到 sdk/cliproxy/auth 包中(例如,在 priority.go 文件里),并将其导出为 ParsePriorityFromInterface。这样,此文件和 sdk/auth/filestore.go 都可以使用这个共享函数。

这个 parsePriorityValue 函数是 internal/api/handlers/management/auth_files.go 中函数的副本。为了提高可维护性,应在此处删除该函数,并使用共享版本。我已在另一个文件中提出了建议,将此逻辑移动到 sdk/cliproxy/auth 包中。

数字 2_147_483_640 像是一个魔法数,可能意在防止 32 位系统上的整数溢出,因为它接近 math.MaxInt32。为了更好的清晰度和可维护性,最好使用命名常量或更具自描述性的值。例如,您可以定义一个像 const maxRoundRobinIndex = 2_000_000_000 这样的常量,或者直接使用一个大的整数,以清楚地表明其用途。

Suggested change
if index >= 2_147_483_640 {
index = 0
}
if index >= 2_000_000_000 { // 重置以避免溢出
index = 0
}
