Wechat Official Account Node

Overview

This node integrates with the Wechat Official Account platform to retrieve user information. Specifically, for the "用户" (User) resource and the "获取用户信息" (Get User Info) operation, it fetches details about a specific user identified by their OpenID within the current official account context.

Common scenarios where this node is useful include:

• Personalizing messages or content based on user profile data.
• Managing user data synchronization between Wechat and other systems.
• Building customer support workflows that require fetching user details dynamically.

For example, you might use this node to get a user's language preference and display content accordingly or to verify user identity before processing requests.

Properties

Output

The node outputs JSON data containing the user's information as returned by the Wechat Official Account API. This typically includes fields such as nickname, gender, location, language, subscription status, and other profile details depending on the API response.

If the node supports binary data output (not indicated in the provided code), it would represent media or files related to the user, but here the focus is purely on JSON user profile data.

Dependencies

• Requires an active connection to the Wechat Official Account API.
• Needs an API authentication credential configured in n8n to authorize requests.
• The node depends on internal helper modules for resource and operation management, but these are bundled internally and do not require external installation.

Troubleshooting

• Common issues:

  • Invalid or missing OpenID will cause the API call to fail.
  • Incorrect or expired API credentials will result in authentication errors.
  • Network connectivity problems can prevent successful API calls.

• Error messages:

  • "未实现方法: 用户.获取用户信息" ("Unimplemented method: 用户.获取用户信息") indicates the requested resource-operation pair is not supported or incorrectly specified.
  • API error messages from Wechat (e.g., invalid token, user not found) will be propagated and should be checked against Wechat's API documentation.

• Resolutions:

  • Verify the OpenID value is correct and corresponds to a subscribed user.
  • Ensure the API credentials are valid and have necessary permissions.
  • Check network access and proxy settings if applicable.
  • Use the node’s "Continue On Fail" option to handle individual item errors gracefully in batch executions.
