您好，您遇到的重定向循环问题，即在 /user/messaging、/user/login?return_to=/user/messaging 和 /user/login 之间反复跳转，通常是由于客户端的身份验证状态检查和页面重定向逻辑存在冲突或竞争条件。

在分析了您提供的代码（特别是 main.js、ui-messaging.js 和 worker.js 的相关部分）后，我判断问题主要出在客户端 JavaScript 如何确定用户登录状态以及何时执行页面跳转。当这些逻辑不够集中或执行顺序不当时，就可能出现您描述的循环。

为了解决这个问题，我建议对 main.js 中的 checkLoginStatus 和 displayCorrectView 函数进行重构，使其职责更清晰，并调整 /user/messaging 页面的初始化方式。

核心思路：

  1. checkLoginStatus: 此函数将成为判断用户是否登录、是否需要重定向的唯一决策点。它会首先调用 /api/me 检查会话。
    • 如果用户已登录：
      • 若当前在登录/注册页面，则根据 return_to 参数或默认规则跳转到账户页面或目标页面。
      • 若当前在受保护页面（如 /user/account, /user/messaging），则调用 displayCorrectView 更新UI，并继续加载页面内容。
    • 如果用户未登录：
      • 若当前在受保护页面，则重定向到登录页，并附带 return_to 参数。
      • 若当前在公共页面（如登录页），则调用 displayCorrectView 显示相应表单。
  2. displayCorrectView: 此函数将只负责根据 checkLoginStatus 提供的用户数据（或null）来更新页面的显示元素（如顶部栏、侧边栏显隐、表单显隐等），不再执行任何页面跳转逻辑。
  3. /user/messaging 页面初始化: 在 main.js 的 WorkspaceAppConfigAndInitialize 函数中，将在 checkLoginStatus 完成后，如果确定用户已登录且当前页面是 /user/messaging，才调用 ui-messaging.js 中的 loadMessagingTabData。

以下是建议的修改方案：

1. my/src/worker.js
您在 worker.js 中为 /user/messaging 添加的路由和未登录重定向逻辑是正确的，无需更改。

// (现有 worker.js 代码保持不变，特别是 /user/messaging 路由部分)
// ...if (method === 'GET' && path === '/user/messaging') {if (!userEmailFromSession) { // Redirect to login if not authenticatedconst loginUrl = new URL(`${OAUTH_ISSUER_URL(env, request)}/user/login`);loginUrl.searchParams.set('return_to', path); // Return to messaging page after loginreturn Response.redirect(loginUrl.toString(), 302);}return new Response(generateMessagingPageHtml(env), { headers: { 'Content-Type': 'text/html;charset=UTF-8' } });}
// ...

2. cdn/js/main.js
这是主要的修改部分。我们将重构 checkLoginStatus 和 displayCorrectView，并调整初始化流程。

解释：

  • main.js -> checkLoginStatus():
    • 此函数现在是身份验证和重定向的主要控制点。
    • 它首先调用 /api/me。
    • 如果已登录：
      • 如果当前在 /user/login, /user/register, 或 / 页面，它会检查 return_to 参数，如果存在则跳转到该参数指定的页面，否则跳转到 /user/account。然后函数返回，阻止后续代码执行。
      • 如果当前在其他页面（如 /user/account, /user/messaging, /user/help），它会调用 displayCorrectView(userData) 更新UI，然后正常继续。
    • 如果未登录：
      • 如果当前在受保护的页面 (如 /user/account, /user/messaging, /user/help)，它会重定向到 /user/login 并附带 return_to 参数（包含原始页面的完整路径、查询参数和哈希）。然后函数返回。
      • 如果当前在公共页面（如 /user/login），它会调用 displayCorrectView(null) 来显示登录表单。
    • 函数返回一个布尔值，指示是否发生了重定向。
  • main.js -> displayCorrectView(userData):
    • 此函数现在只负责根据传入的 userData 更新UI（显示/隐藏元素，填充用户信息等）。它不再执行任何重定向。
    • 特别为 /user/messaging 页面添加了 messaging-page-layout 类，并相应调整了侧边栏和主内容区域的显隐。
  • main.js -> WorkspaceAppConfigAndInitialize():
    • 现在会 await checkLoginStatus()。
    • 如果 checkLoginStatus 没有导致重定向，并且当前页面是 /user/messaging 且用户已登录，它会调用 window.loadMessagingTabData()。
  • ui-messaging.js:
    • 移除了底部的 DOMContentLoaded 监听器。loadMessagingTabData 现在由 main.js 中的 WorkspaceAppConfigAndInitialize 在正确的时机调用。
    • loadMessagingTabData 内部依赖 window.currentUserData（应由 main.js 的 checkLoginStatus 设置）。
  • html-ui.js:
    • _generateTopBarHtml 调整了 siteTitleLink 的逻辑，使其在私信页面能正确链接回账户设置。
    • _generateScripts 在 generateHelpPageHtml, generateConsentScreenHtml, generateErrorPageHtml 中现在总是包含所有UI脚本 (includeAllUiScripts = true)，以确保像主题切换这样的全局功能在所有页面上都能正常工作。

通过这些更改，身份验证流程应该更加健壮，可以防止因客户端状态判断不准确或重定向逻辑冲突而导致的循环。当用户访问 /user/messaging 时：

  1. worker.js 首先检查服务器端会话。如果未登录，则重定向到 /user/login?return_to=/user/messaging。
  2. 如果已登录（或在登录后），浏览器加载 /user/messaging。
  3. 客户端 main.js 中的 WorkspaceAppConfigAndInitialize -> checkLoginStatus 会确认登录状态。
  4. 由于已登录且在 /user/messaging 页面，checkLoginStatus 不会重定向，而是调用 displayCorrectView 设置正确的UI。
  5. 之后，WorkspaceAppConfigAndInitialize 会调用 loadMessagingTabData 来加载私信数据。

请您将这些修改应用到对应的文件中，并测试是否解决了重定向循环的问题。
