Overview
This node integrates with the Wechat Official Account platform to manage user-related operations. Specifically, the "拉黑用户" (Blacklist User) operation allows you to add one or more users to a blacklist, preventing them from interacting with your official account. This is useful for managing unwanted interactions, spam, or abusive users.
A common scenario is when an administrator wants to block multiple users at once by specifying their unique OpenIDs. For example, if you receive spam messages from certain users, you can batch blacklist up to 20 of them in a single operation to efficiently restrict their access.
Properties
| Name | Meaning |
|---|---|
| OpenID列表 | A list of user OpenIDs to be blacklisted. You can specify up to 20 OpenIDs per operation. |
The "OpenID列表" property is a fixed collection that supports multiple values. Each entry requires an "Openid" string representing the unique identifier of a user on the Wechat platform.
Output
The node outputs JSON data representing the result of the blacklist operation for each input item. Each output item corresponds to an input and contains either the success response or an error message if the operation failed.
If the operation encounters errors and the node is configured to continue on failure, the output will include an error field describing the issue for the affected items.
No binary data output is produced by this node.
Dependencies
- Requires valid credentials for accessing the Wechat Official Account API, specifically an API key or token with permissions to manage user blacklists.
- The node depends on internal helper modules for resource and operation management but does not require additional external libraries beyond those bundled.
- Proper configuration of the Wechat Official Account credentials within n8n is necessary for successful execution.
Troubleshooting
Common Issues:
- Providing more than 20 OpenIDs in a single batch will likely cause an error due to API limits.
- Invalid or expired API credentials will result in authentication failures.
- Network issues or API rate limiting may cause intermittent failures.
Error Messages:
- Errors returned from the Wechat API are captured and included in the output under the
errorfield if "continue on fail" is enabled. - If "continue on fail" is disabled, the node throws an error stopping execution, indicating the specific problem encountered.
- Errors returned from the Wechat API are captured and included in the output under the
Resolution Tips:
- Ensure the OpenID list does not exceed 20 entries.
- Verify that the API credentials are correctly set up and have the required permissions.
- Check network connectivity and API usage quotas.
