loginCCNUPassport 爬虫函数在发送 http 请求时使用了业务上下文，导致首次 http 请求失败时 ctx 被取消，Retry 无法进行

📝 Walkthrough

Walkthrough

登录 POST 请求现在使用基于 context.Background() 的独立 1 秒超时上下文。函数返回时会调用取消函数。该请求不再继承调用方上下文。

未发现关键问题。

Merge Risk: 🟡 Moderate · up to 1afd5

登录请求虽然增加了 1 秒超时，但会忽略调用方取消和更早的截止时间，导致已取消的登录仍继续执行；合并前应改为从调用方上下文派生超时。

让登录请求继承调用方的 ctx。

loginCCNUPassport 接收了 LoginPassport 的 ctx，但在第 139 行使用 context.Background() 创建超时上下文。调用方取消或客户端断开后，CAS 登录 POST 仍可能继续执行最多 1 秒。

请改用 context.WithTimeout(ctx, time.Second)，并将派生上下文传给 http.NewRequestWithContext。同时增加父上下文取消期间的回归测试。
