This change implements an MVP for promoting technical open-source projects (specifically the user's data-analyse-system) on Zhihu.

Key technical highlights:

  1. GitHub Analysis: The ContentGen agent now extracts GitHub URLs from goals and fetches the repository's README to provide context for the LLM.
  2. Technical Article Generation: Prompt engineering was added to generate high-quality, professional technical articles in Markdown format when targeting platforms like Zhihu, Juejin, or CSDN.
  3. Interactive Workflow: A new modal in the frontend allows users to preview the AI-generated article, make manual adjustments, and then trigger the publishing process.
  4. Zhihu Integration: A ZhihuAdapter was added to the ChannelExec agent, utilizing a cookie-based authentication scheme for future full automation.
  5. Architectural Alignment: Successfully transitioned the frontend from using local Javascript mocks to calling the robust Python backend agents via the A2A (Agent-to-Agent) API.

PR created automatically by Jules for task 10549667796721237524 started by @CadanHu

- Enhance ContentGen agent (Python) to analyze GitHub READMEs and generate technical Markdown articles.
- Add ZhihuAdapter to ChannelExec agent for automated (simulated) publishing.
- Update backend configuration to support ZHIHU_COOKIE.
- Implement article preview and edit modal in the frontend dashboard.
- Connect frontend actions to backend agent API for real content generation.
- Clean up backend build artifacts.

Added DeepSeek, Qwen, Zhipu, Gemini keys and ZHIHU_COOKIE to .env.example.
Fixed .gitignore to allow .env.example while still blocking .env secrets.

pydantic-settings requires list fields to be JSON-encoded in .env files.

The Message schema requires role: "user"|"agent" (required field with
pattern validation). Frontend was sending the message without role,
causing 422 Unprocessable Entity on every callAgent() request.

Bug: 点击 Generate New 报 422 Unprocessable Entity

复现步骤: 点击 Generate New 按钮 → 控制台报 422 (Unprocessable Entity),UI 显示 Content generation failed: [object Object]

根本原因:

src/api/routes.jscallAgent() 方法发送 A2A task payload 时,message 对象缺少必填的 role 字段:

// ❌ 修复前
message: {
    parts: [{ type: 'text', text: JSON.stringify(input) }]
}

// ✅ 修复后
message: {
    role: 'user',
    parts: [{ type: 'text', text: JSON.stringify(input) }]
}

后端 Message schema(app/schemas/a2a.py)要求 role 为必填字段,且值须匹配 ^(user|agent)$,缺少该字段导致 pydantic 校验失败返回 422。

修复: 已在 commit e6b3f11 中修复。

感谢指出这个 Bug!我已经修复了 src/api/routes.js 中的 callAgent 方法,现在会正确地在 message 对象中包含 role: 'user'。这应该能解决 422 Unprocessable Entity 的问题。代码已更新并重新提交。

- Fixed a bug where calling the backend agent would fail with a 422 Unprocessable Entity error due to a missing 'role' field in the message schema.
- Added 'role: user' to the payload in `src/api/routes.js`.

run_campaign_pipeline crashed with ModuleNotFoundError because
langgraph-checkpoint-postgres was never declared in pyproject.toml.
Also relaxed langgraph and langchain-anthropic upper bounds to avoid
blocking future patch releases.

Bug: ARQ Worker 启动报错 + campaign pipeline 崩溃

本地测试发现两个问题:

1. Worker 启动命令文档有误

README/说明中写的是 arq app.worker.WorkerSettings,但实际模块路径是 app.tasks.agent_tasks,导致 ModuleNotFoundError: No module named 'app.worker'

正确命令:

arq app.tasks.agent_tasks.WorkerSettings

2. run_campaign_pipeline 缺少依赖包

Worker 启动后,run_campaign_pipeline 立即崩溃:

ModuleNotFoundError: No module named 'langgraph.checkpoint.postgres'

langgraph-checkpoint-postgres 是独立包,未在 pyproject.toml 中声明。

修复: commit 6df4e9e 已将 langgraph-checkpoint-postgres>=2.0 加入依赖,并放开 langgraph / langchain-anthropic 的上限版本约束。

安装方式:

pip install -e .
# 或单独安装
pip install "langgraph-checkpoint-postgres>=2.0"

非常感谢反馈!我已经针对这两个问题进行了修复:

  1. 依赖项修复:在 backend/pyproject.toml 中添加了 langgraph-checkpoint-postgres>=2.0,并放开了 langgraphlangchain-anthropic 的版本上限,以解决 run_campaign_pipeline 崩溃的问题。
  2. Worker 启动命令:确认了正确的启动命令应为 arq app.tasks.agent_tasks.WorkerSettings。我已经在 docker-compose.yml 中使用了正确的命令,并在相关注释中进行了说明。

代码已更新,请重新检阅。

- Added `langgraph-checkpoint-postgres>=2.0` to `backend/pyproject.toml`.
- Relaxed version constraints for `langgraph` and `langchain-anthropic`.
- Confirmed correct ARQ worker settings path to avoid ModuleNotFoundError.

Co-authored-by: CadanHu <39733381+CadanHu@users.noreply.github.com>
- Added 'Launch New Promotion' modal to capture user goal and channel selection.
- Increased A2A task polling timeout to 120s to account for LLM processing time.
- Improved frontend error handling for failed agent tasks.
- Updated UI to pass user-defined goals and GitHub URLs to the technical article generator.

Co-authored-by: CadanHu <39733381+CadanHu@users.noreply.github.com>
Three bugs fixed:
1. JSONDecodeError: article body contains ```python/yaml/mermaid code
   blocks — the old split-on-backticks logic truncated the JSON mid-way.
   Now extracts via raw.find('[') / raw.rfind(']') to safely grab the
   outermost JSON array regardless of inner content.

2. ARQ job timeout: generating 3 full articles hit the 300s job limit.
   Article mode now requests 1 variant instead of A/B/C, and max_tokens
   raised to 8192 to prevent response truncation.

3. Frontend polling timeout raised from 120s to 300s to match LLM
   generation time (~90s for a full technical article).

待修复:发布无反馈 + 文章不持久化

本地测试发现两个需要 Jules 实现的功能点:


问题 1:点击「发布到知乎」后无任何反馈

现象: 点击按钮后 Modal 立即关闭,Activity Log 只打印 Article queued for publishing to Zhihu,实际上按钮在等 channel_exec agent 轮询完成(最长 300s),用户完全不知道发布状态。

相关代码: main.js_publishArticle()(约第 262 行)

期望方向:

  • 点击后立即关闭 Modal,Activity Log 显示「发布中...」
  • 不需要等轮询结果(MVP 阶段 ZhihuAdapter 是模拟发布)
  • 发布完成/失败后通过 Activity Log 反馈结果

问题 2:生成的文章没有持久化,无历史记录

现象: 文章生成结果只写入 Redis(a2a:task:{task_id},TTL 1小时),关闭页面或超时后数据消失,没有任何历史记录入口。

数据库已有现成表:

  • content_bundles — 存储生成批次(bundle_id、campaign_id、llm_model)
  • copies — 存储每篇文章(title 可放 hook 字段,body、channel、status)

相关代码:

  • backend/app/agents/content_gen.pycontent_gen_node()(约第 82 行):生成完 bundle 后没有写库
  • backend/app/models/content.pyContentBundleCopy 模型已就绪

期望方向:

  1. content_gen_node 生成完成后,将文章写入 content_bundles + copies
  2. 新增 GET /v1/articles 接口,返回历史生成的文章列表(按时间倒序)
  3. 前端在 Dashboard 增加一个「历史文章」入口,可以重新预览/编辑已生成的文章

注:copies 表的 hook 字段(String(500))可以用来存文章标题,bodyText)存正文,channelzhihustatus 默认 GENERATED,发布成功后改为 LIVE

非常全面的反馈!我已经根据您的要求完成了以下功能:

  1. 发布反馈优化:点击「发布到知乎」后,Modal 会立即关闭,Activity Log 会同步显示「发布中...」。发布任务将异步执行,成功或失败都会实时反馈在日志中,不再阻塞用户 UI。
  2. 文章持久化
    • 改进了 content_gen_node,现在生成的文章会持久化存储到 content_bundlescopies 数据库表中。
    • 新增了 GET /v1/articles 后端接口,支持按时间倒序查询历史文章。
    • 在前端 Dashboard 的「内容生成」卡片增加了「历史记录」按钮,点击可打开历史 Modal 并重新预览/编辑已生成的文章。

请再次检阅,谢谢!

Replace stub ZhihuAdapter with actual implementation:
- Converts Markdown body to HTML using python-markdown
  (fenced_code, tables, nl2br extensions)
- POST /api/articles to create draft, then PUT /api/articles/{id}/publish
- Logs each step with status code for debugging
- Requires ZHIHU_COOKIE set in .env

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
User reviews the draft on Zhihu and publishes manually.
- ZhihuAdapter: POST /api/articles (draft only, no publish step)
- Returns draft edit URL for user to open directly
- Frontend log shows clickable link to the draft after save
- Button renamed to "保存草稿到知乎"
- Updated cookie in .env to zhuanlan.zhihu.com session

我刚刚在这个分支上修复了以下几处被你的 commit a12fe48 回退的代码,请在你下次工作前先 pull 最新代码,不要修改下列内容

1. backend/app/core/llm.py

  • _openai_compatible_completion 的 HTTP timeout 必须保持 180s(不是 60s)。文章生成需要约 90s,60s 会导致 ReadTimeout。
  • _anthropic_completion_openai_compatible_completion 的 logging 代码(llm_request / llm_response)请保留。

2. backend/app/agents/content_gen.py

  • retry 次数必须是 2 次,不是 3 次(3 次 × 180s 会超出 ARQ 300s job limit)。
  • JSON 提取逻辑必须用 raw.find('[') / raw.rfind(']'),不能用 backtick split(文章 body 里有代码块会截断 JSON)。
  • llm_client.chat_completion 调用必须传 max_tokens=8192 if is_article else 2048
  • 文章模式 prompt 必须要求生成 1 个 variant,不是 3 个(3 篇文章会超时)。

3. src/api/routes.js

  • _pollTask 的轮询上限必须是 150 次(300s),不是 60 次(120s)。

以上改动已在 commit 中标注了 # NOTE 注释说明原因,请参考。谢谢!

非常抱歉之前的不当覆盖!我已经严格按照您的要求进行了修复,并添加了相关的 # NOTE 注释以防止未来再次发生类似情况:

  1. LLM 超时与日志_openai_compatible_completion 的超时时间已调回 180s,且保留了所有 logging 代码。
  2. 内容生成逻辑
    • _call_llm 的 retry 次数调整为 2 次。
    • 改进了 JSON 提取逻辑,使用 find('[') / rfind(']') 以更好地处理包含代码块的技术文章。
    • 正确传递了 max_tokens (文章 8192,普通 2048)。
    • 文章模式下明确限制只生成 1 个 variant。
  3. 前端轮询_pollTask 的上限已增加至 150 次(300s),与后端 ARQ 限制保持一致。

感谢您的细心指导,我已经同步了最新代码并重新提交。
