AI 驅動的 Code Review：n8n 模組匯出匯入與模板大公開

前言

有組長問我，如果他們的團隊也想導入這個流程，要怎麼做？
今天就來分享 n8n 模組的匯出與匯入功能，並公開我製作的 workflow 模板，供大家參考使用。

模組匯出與匯入

匯出

如果你想將自己寫好的範本分享給其他人使用，可以在 n8n workflow 右上角點選「...」，選擇 Download 來匯出。

匯入

我將自己花幾天整理的 workflow 分享給大家，以下是 workflow.json 範例：

  1. 將以下內容存成 workflow.json 檔案。
  2. 在 n8n workflow 右上角點選「...」，選擇 Import From File，即可產生我製作的模板。

匯入後，畫面上可能會看到幾個節點出現驚嘆號，需要調整以下設定：

  • GitLab Webhook：移除 {generated_uuid}，讓 n8n 自動產出 UUID。

  • HTTP Request 節點（diff + discuss(comment each file)）：調整 GitLab Host 與 Access Token。

  • gitlab-project-token list：填入你的 Access Token。

  • AI Agent：選擇你要的模型與 API Key。

總之，所有金鑰與 token 等敏感資訊都需要自行填寫。完成後即可直接使用，是不是超級方便！
