Wechat Official Account Node

Actions43

Overview

This node integrates with the Wechat Official Account platform, enabling users to perform various operations related to Wechat resources. Specifically, for the resource "素材" (media material), it supports uploading temporary media files such as images, voice recordings, videos, and thumbnails.

A common use case is automating the upload of media content to a Wechat Official Account, which can then be used in messages, posts, or other interactions within the Wechat ecosystem. For example, a marketing automation workflow might upload promotional images or videos dynamically before sending them out to subscribers.

Properties

Name Meaning
媒体文件类型 The type of media file to upload. Options include: 图片 (image), 语音 (voice), 视频 (video), 缩略图 (thumbnail).
文件 The name of the input field containing the binary data of the file to upload. This should match the binary property name from the input data panel.

Output

The node outputs an array of JSON objects representing the result of the upload operation for each input item processed. Each output item contains metadata about the uploaded media, such as identifiers or URLs returned by the Wechat API.

If the node processes multiple items, the output will contain corresponding results for each, preserving the order.

Binary data is not output by this node; it only returns JSON metadata about the uploaded media.

Dependencies

  • Requires valid credentials for accessing the Wechat Official Account API, specifically an API key or token that authorizes media uploads.
  • The node depends on the Wechat Official Account API endpoints for media management.
  • No additional external services are required beyond the official Wechat API.
  • Proper configuration of credentials in n8n is necessary for successful authentication.

Troubleshooting

  • Common issues:

    • Incorrect or missing binary data field name: Ensure the "文件" property matches exactly the name of the binary input field containing the media file.
    • Unsupported media type: Verify that the media file type corresponds to one of the supported options (image, voice, video, thumbnail).
    • Authentication errors: Confirm that the API credentials are correctly configured and have sufficient permissions.
    • Network or API rate limits: Large volumes of uploads may hit Wechat API limits; consider adding delays or error handling.

  • Error messages:

    • "未实现方法: 素材.上传临时素材" (Method not implemented): Indicates the requested resource-operation combination is not supported or incorrectly specified.
    • Errors related to invalid binary data or missing fields usually mention the input field name; double-check the property settings.
    • Authentication failures typically return errors about invalid tokens or unauthorized access; reconfigure credentials accordingly.
