Overview
This node is an example custom n8n node designed to demonstrate how to create and use custom nodes within n8n workflows. Specifically, for the "用户" (User) resource with the "获取" (Get) operation, it retrieves a single user's information based on a provided user ID. This can be useful in scenarios where you want to fetch user details from a system or database by specifying their unique identifier.
Practical examples include:
- Retrieving user profile data to personalize communications.
- Fetching user details before performing updates or validations.
- Integrating user data retrieval into larger automation workflows.
Properties
| Name | Meaning |
|---|---|
| 用户ID | The ID of the user to retrieve. |
Output
The output is a JSON object representing the user data with the following structure:
{
"id": "string", // The user ID as provided in input
"name": "示例用户", // A sample user name (literal: "Example User")
"email": "user@example.com" // A sample user email address
}
This output provides basic user information including ID, name, and email.
Dependencies
- No external API calls or services are used; the node returns static example data.
- Requires an API key credential configured in n8n (generic exampleCredentials) to operate, though this is only illustrative.
Troubleshooting
Common issues:
- Missing or empty 用户ID property will likely cause the node to fail or return incomplete data since the user ID is required.
- Since this is an example node returning static data, no real user lookup occurs; users expecting dynamic data should implement actual API integrations.
Error messages:
- If an error occurs during execution, the node will throw the error message unless "Continue On Fail" is enabled, in which case it outputs an error object with the message.
