N8n Node Configuration 操作模式

# 操作模式指南 按节点类型和操作组织的常见节点配置模式。 --- ## 概述 **目的**：常见节点配置的快速参考 **覆盖范围**：525 个可用节点中 20 个最常用的节点 **模式格式**： - 最小有效配置 - 常见选项 - 实际案例 - 注意事项与技巧 --- ## HTTP 与 API 节点 ### HTTP 请求 (nodes-base.httpRequest) 用于 HTTP 操作的最通用节点 #### GET 请求 **最小配置**： javascript { "method": "GET", "url": "https://api.example.com/users", "authentication": "none" } **带查询参数**： javascript { "method": "GET", "url": "https://api.example.com/users", "authentication": "none", "sendQuery": true, "queryParameters": { "parameters": [ { "name": "limit", "value": "100" }, { "name": "offset", "value": "={{$json.offset}}" } ] } } **带身份验证**： javascript { "method": "GET", "url": "https://api.example.com/users", "authentication": "predefinedCredentialType", "nodeCredentialType": "httpHeaderAuth" } #### POST (JSON 格式) **最小配置**： javascript { "method": "POST", "url": "https://api.example.com/users", "authentication": "none", "sendBody": true, "body": { "contentType": "json", "content": { "name": "John Doe", "email": "[email protected]" } } } **带表达式**： javascript { "method": "POST", "url": "https://api.example.com/users", "authentication": "none", "sendBody": true, "body": { "contentType": "json", "content": { "name": "={{$json.name}}", "email": "={{$json.email}}", "metadata": { "source": "n8n", "timestamp": "={{$now.toISO()}}" } } } } **注意**：对于 POST/PUT/PATCH，请记住设置 `sendBody: true`！ #### PUT/PATCH 请求 **模式**：与 POST 相同，仅方法不同 javascript { "method": "PUT", // 或 "PATCH" "url": "https://api.example.com/users/123", "authentication": "none", "sendBody": true, "body": { "contentType": "json", "content": { "name": "Updated Name" } } } #### DELETE 请求 **最小配置** (无 body)： javascript { "method": "DELETE", "url": "https://api.example.com/users/123", "authentication": "none" } **带 body** (部分 API 允许)： javascript { "method": "DELETE", "url": "https://api.example.com/users", "authentication":
