n8n 工作流管理

通过 API 管理 n8n 工作流和自动化任务。适用于处理 n8n 工作流、执行或自动化任务时——如列出工作流、激活/停用、检查执行状态、手动触发工作流或调试自动化问题。

n8n 工作流管理 是什么?

该技能提供了一套全面的 n8n 工作流自动化管理工具,涵盖创建、测试、执行监控和性能优化。其核心功能包括通过命令行脚本或 Python API 与 n8n 实例交互,支持列出、创建、激活/停用工作流,以及进行验证、试运行、测试套件等测试与验证操作。执行监控方面可查看执行列表、详情并手动触发工作流。性能优化模块能分析执行指标、检测瓶颈并提供分级优化建议(如并行执行、缓存、批处理)。此外,该技能还特别强调工作流创建规则:必须生成包含所有实际功能节点(如 HTTP 请求、代码节点)的完整工作流,严禁使用占位节点或不完整的 TODO。所有操作均由 Python 脚本(n8n_api.py, n8n_tester.py, n8n_optimizer.py)驱动,支持 OpenClaw 环境。

n8n 工作流管理 是做什么的?

为 n8n 平台提供全面的工作流自动化管理功能,包括创建、测试、执行监控和性能优化。

⚠️ 关键:工作流创建规则

创建 n8n 工作流时,务必遵守以下规则:

  1. ✅ 生成完整的工作流,包含所有功能节点
  2. ✅ 包含实际的 HTTP 请求节点,用于 API 调用(如 ImageFX、Gemini、Veo、Suno 等)
  3. ✅ 添加代码节点,用于数据转换和逻辑处理
  4. ✅ 在所有节点之间创建正确的连接
  5. ✅ 使用真实的节点类型(如 n8n-nodes-base.httpRequest、n8n-nodes-base.code、n8n-nodes-base.set)

绝对禁止:

  • ❌ 创建“设置指南”占位节点
  • ❌ 生成仅包含 TODO 注释的工作流
  • ❌ 制作不完整、需要手动添加节点的工作流
  • ❌ 使用纯文本节点替代实际功能

正确的工作流示例:

手动触发 → 设置配置 → HTTP 请求(API 调用) → 代码(解析) → 响应

错误的工作流示例:

手动触发 → 代码(“在此添加 HTTP 节点,配置 API...”)

请始终构建完整、可用的工作流,确保所有必要节点均已配置并连接。

设置

必需的环境变量:

  • N8N_API_KEY — 您的 n8n API 密钥(在 n8n 界面中通过“设置 → API”获取)
  • N8N_BASE_URL — 您的 n8n 实例 URL

通过 OpenClaw 设置配置凭据:

添加到 ~/.config/openclaw/settings.json:

{
  "skills": {
    "n8n": {
      "env": {
        "N8N_API_KEY": "your-api-key-here",
        "N8N_BASE_URL": "your-n8n-url-here"
      }
    }
  }
}

或者每次会话设置(不要将密钥持久保存到 shell rc 文件中):

export N8N_API_KEY="your-api-key-here"
export N8N_BASE_URL="your-n8n-url-here"

验证连接:

python3 scripts/n8n_api.py list-workflows --pretty

**安全提示:**切勿将 API 密钥以明文形式存储在 shell 配置文件(~/.bashrc、~/.zshrc)中。请使用 OpenClaw 设置文件或安全的密钥管理器。

解决方案:

  1. 验证 API 密钥是否正确
  2. 检查 N8N_BASE_URL 是否正确设置
  3. 确认 n8n 中已启用 API 访问

验证错误

**解决方案:**检查工作流 JSON 结构,确保所有必需字段都存在

执行超时

状态:超时——执行未完成

解决方案:

  1. 检查工作流中是否存在无限循环
  2. 减小测试数据集大小
  3. 优化高开销操作
  4. 在工作流设置中设置执行超时时间

  2. 实现指数退避
  3. 使用批处理
  4. 检查 API 速率限制

凭据缺失

警告:节点“HTTP_Request”可能需要凭据

解决方案:

  1. 在 n8n 界面中配置凭据
  2. 将凭据分配给节点
  3. 在激活前测试连接
