Wechat Official Account Node

Actions43

Overview

This node integrates with the Wechat Official Account platform, specifically providing functionality to upload images within graphic messages (图文消息). It is useful when you want to programmatically add or update images embedded in Wechat articles or posts. Typical use cases include automating content publishing workflows where images need to be uploaded and linked inside Wechat official account posts.

Properties

Name Meaning
文件 (inputDataFieldName) The name of the input field containing the binary file data to be uploaded as an image. This should match the field name in the binary tab of the input panel where the image data is provided. Example: "data".

Output

The node outputs JSON data representing the result of the image upload operation. Each item corresponds to one input item processed and contains either the successful response from the upload or an error message if the upload failed.

If the upload involves binary data, it is expected that the node consumes binary input but does not output binary data itself; instead, it returns metadata about the uploaded image.

Dependencies

  • Requires valid credentials for accessing the Wechat Official Account API (an API key or token must be configured).
  • The node depends on internal resource and operation modules dynamically loaded at runtime.
  • No additional external services beyond the Wechat Official Account API are required.

Troubleshooting

  • Common issues:

    • Incorrect or missing binary input field name will cause the node to fail to find the image data.
    • Invalid or expired API credentials will result in authentication errors.
    • Network or API rate limiting issues may cause intermittent failures.

  • Error messages:

    • "未实现方法: 素材.上传图文消息内的图片" indicates the operation is not implemented or incorrectly referenced.
    • Errors related to missing binary data field suggest verifying the 文件 property matches the actual input binary field name.
    • Authentication errors require checking the configured API credentials.

To resolve these, ensure the binary input field name is correct, credentials are valid, and network connectivity to the Wechat API is stable.
