编辑字段（设置）#

使用编辑字段节点来设置工作流数据。该节点既能设置新数据，也能覆盖已存在的数据。在需要接收前置节点数据的场景中（例如向Google表格或数据库插入值时），此节点至关重要。

节点参数#​

以下是编辑字段节点中可用的设置选项。

模式#​

可选择使用手动映射通过图形界面编辑字段，或选择JSON输出编写由n8n添加到输入数据中的JSON。

待设置字段#​

选择模式 > 手动映射时，可通过从输入区域拖拽数值来配置字段。

拖拽数值时的默认行为是：

  • n8n将数值名称设为字段名
  • 字段值包含访问该数值的表达式

若需禁用表达式：

  1. 将鼠标悬停在字段上，n8n将显示固定值｜表达式切换开关
  2. 选择固定值 此操作可同时应用于字段名称和字段值

仅保留设置字段#​

启用后将丢弃未在待设置字段中使用的所有输入数据。

输出包含内容#​

选择在节点输出数据中要包含哪些输入数据。

节点选项#​

通过以下选项自定义节点行为。

包含二进制数据#​

若输入数据包含二进制数据，可选择是否将其包含在编辑字段节点的输出数据中。

忽略类型转换错误#​

仅限手动映射模式。 启用后允许n8n在映射字段时忽略某些数据类型错误。

支持点标记法#​

n8n默认支持点标记法。 例如使用手动映射时，节点会遵循名称字段的点标记法。若将名称字段设为number.one，值字段设为20，最终生成的JSON为：

{ "number": { "one": 20} }

您可以通过选择 添加选项 > 支持点符号，并将 点符号 字段设置为关闭来阻止此行为。现在生成的 JSON 为：

{ "number.one": 20 }

JSON输出模式中的数组与表达式#​

创建JSON输出时，您可以使用数组和表达式。

例如，根据客户数据存储节点生成的输入数据：

[
  {
    "id": "23423532",
    "name": "Jay Gatsby",
    "email": "gatsby@west-egg.com",
    "notes": "Keeps asking about a green light??",
    "country": "US",
    "created": "1925-04-10"
  },
  {
    "id": "23423533",
    "name": "José Arcadio Buendía",
    "email": "jab@macondo.co",
    "notes": "Lots of people named after him. Very confusing",
    "country": "CO",
    "created": "1967-05-05"
  },
  {
    "id": "23423534",
    "name": "Max Sendak",
    "email": "info@in-and-out-of-weeks.org",
    "notes": "Keeps rolling his terrible eyes",
    "country": "US",
    "created": "1963-04-09"
  },
  {
    "id": "23423535",
    "name": "Zaphod Beeblebrox",
    "email": "captain@heartofgold.com",
    "notes": "Felt like I was talking to more than one person",
    "country": null,
    "created": "1979-10-12"
  },
  {
    "id": "23423536",
    "name": "Edmund Pevensie",
    "email": "edmund@narnia.gov",
    "notes": "Passionate sailor",
    "country": "UK",
    "created": "1950-10-16"
  }
]

在 JSON 输出 字段中添加以下 JSON，并将 包含在输出中 设置为 所有输入字段：

{
  "newKey": "new value",
  "array": [{{ $json.id }},"{{ $json.name }}"],
  "object": {
    "innerKey1": "new value",
    "innerKey2": "{{ $json.id }}",
    "innerKey3": "{{ $json.name }}",
 }
}

您将获得以下输出：

[
  {
    "id": "23423532",
    "name": "Jay Gatsby",
    "email": "gatsby@west-egg.com",
    "notes": "Keeps asking about a green light??",
    "country": "US",
    "created": "1925-04-10",

    "array": [

      "Jay Gatsby"
    ],
    "object": {
      "innerKey1": "new value",
      "innerKey2": "23423532",
      "innerKey3": "Jay Gatsby"
    }
  },
