调研方向

首先检查 Content 模块现有的 endpoint 和 workflow 模式,然后检查 dependency #2 中的 Post 实体和 workflow。使用 tests/CommunityPro.Tests/Members/MembersTestHarness.cs 中的 Members 测试 harness 作为指定的测试参考,并为每个 endpoint 添加 xUnit 覆盖,包括具有恶意内容的 TipTap payload。满足所列出的 authorization、state、validation、sanitization、error-code 和 pagination 标准,即表示完成。

描述

content

Scope

Author-facing endpoints on the Content module. Any active member can write; authors can only touch their own posts.

Method Path Auth Notes
GET /posts/mine active member paginated, all statuses, author only
POST /posts/mine active member create draft
PUT /posts/{id} active member edit own Draft/Rejected post (autosave target — must be cheap)
POST /posts/{id}/submit active member Draft → Submitted

Sanitization

On submit, produce ContentHtml from the TipTap payload server-side using HtmlSanitizer. Store both: ContentJson for re-editing, sanitized ContentHtml as the only thing public pages ever render. Never trust or render raw author HTML.

Validation

Title/excerpt length caps, tag whitelist + max count, cover image URL must be an allowed image host (see MemberProfileService.IsAllowedAvatarHttpsUrl for the pattern and host list).

Error codes

content.not_found, content.not_author, content.invalid_state, content.invalid_post

Dependencies

Blocked by #2 (Post entity + workflow).

Acceptance criteria

  • Non-author gets content.not_author (404-shaped, no existence leak, matching project convention)
  • Editing a Submitted/Published post fails with content.invalid_state
  • Submit sanitizes: script tags, event handlers, javascript: URLs stripped (tests with hostile payloads)
  • Pending (non-active) members are rejected by the policy
  • xUnit coverage per endpoint
Conventions (project-wide, non-negotiable)
  • .NET 9, records for immutable shapes, file-scoped namespaces, primary constructors where they read well. Minimal-API endpoints grouped per module via IEndpointModule.MapEndpoints.
  • Result<T> (SharedKernel) instead of exception-driven control flow. Endpoint results map failures to ProblemDetails with the stable error codes listed above — the frontend keys off them.
  • Module owns its EF Core DbContext mapped to its own Postgres schema. Modules never reference each other's internals — cross-module needs go through a public contract interface or an in-process domain event (IEventPublisher).
  • All external calls (GitHub, Stripe, Brevo, Cloudinary, Meilisearch) behind interfaces owned by the consuming module.
  • Every list endpoint paginated (offset is fine). xUnit tests in tests/CommunityPro.Tests/<Module>/ following the existing harness patterns (see Members/MembersTestHarness.cs).
