Wechat Official Account Node

Actions43

Overview

This node interacts with the Wechat Official Account platform, specifically enabling operations related to comments on messages. The "打开评论" (Open Comment) operation allows users to open or enable comments on a previously sent message identified by its unique message data ID. This is useful in scenarios where comments were initially disabled or need to be activated after sending a group message.

Practical examples include:

  • Enabling comments on a promotional article sent to followers.
  • Allowing user interaction on a multi-article message by specifying which article's comments to open.

Properties

Name Meaning
消息数据ID The unique identifier (msg_data_id) returned from sending a group message; required to specify which message's comments to open.
图文索引 Index of the article within a multi-article message to specify which article's comments to open; starts at 0. Defaults to 0 if not provided.

Output

The node outputs JSON data representing the result of the "open comment" operation for each input item. The structure typically includes success confirmation or error details if the operation failed. There is no indication that binary data is output by this node.

Example output JSON might look like:

[
  {
    "success": true,
    "msg_data_id": "1234567890",
    "index": 0
  }
]

If an error occurs, the output JSON will contain an error field describing the issue.

Dependencies

  • Requires an API key credential for authenticating with the Wechat Official Account platform.
  • The node depends on internal resource and operation modules dynamically loaded from the resource/*.js files.
  • No additional external services beyond the Wechat Official Account API are indicated.

Troubleshooting

  • Common issues:

    • Providing an invalid or expired msg_data_id will cause the operation to fail.
    • Specifying an out-of-range index for multi-article messages may result in errors.
    • Missing or incorrect API credentials will prevent successful API calls.

  • Error messages:

    • "未实现方法: comment.comment:open" indicates the operation is not implemented or incorrectly referenced.
    • Errors during execution are logged with detailed messages and stack traces.
    • If continueOnFail is enabled, errors for individual items will be returned as JSON objects with an error property instead of stopping the entire workflow.

To resolve errors:

  • Verify the correctness of msg_data_id and index.
  • Ensure valid API credentials are configured.
  • Check that the operation name and resource are correctly set.
