Wechat Official Account Node

Actions43

Overview

This node interacts with the Wechat Official Account platform to retrieve a list of media materials (素材). Specifically, for the "获取素材列表" (Get Material List) operation under the "素材" (media) resource, it fetches batches of media items such as images, videos, voice recordings, or news articles from the user's official account.

Common scenarios where this node is useful include:

  • Managing and displaying media assets stored in a Wechat Official Account.
  • Automating content retrieval for further processing or publishing workflows.
  • Integrating Wechat media content into other systems or databases.

For example, a user might use this node to fetch the first 10 images uploaded to their official account to create a gallery on a website or to analyze media usage statistics.

Properties

Name Meaning
素材类型 The type of media material to retrieve. Options: 图片 (image), 视频 (video), 语音 (voice), 图文 (news)
偏移位置 Offset position to start returning materials from. 0 means starting from the first item.
返回数量 Number of materials to return. Must be between 1 and 20.

Output

The output is a JSON array where each item represents a media material retrieved from the Wechat Official Account. Each JSON object contains the details of one media item according to the selected type (image, video, voice, or news).

If the node supports binary data output (not explicitly shown in the provided code), it would typically represent media files like images or videos in binary form for downstream nodes to process or save.

Dependencies

  • Requires an API key credential for authenticating with the Wechat Official Account platform.
  • The node depends on internal helper modules for resource and operation management.
  • No external environment variables are explicitly required beyond the API credentials.

Troubleshooting

  • Common issues:

    • Invalid or missing API credentials will cause authentication failures.
    • Requesting an offset beyond the available number of materials may return empty results.
    • Specifying a count outside the allowed range (1 to 20) may cause errors or unexpected behavior.

  • Error messages:

    • "未实现方法: 素材.获取素材列表" ("Unimplemented method: media.batchGetMaterial") indicates that the requested resource-operation combination is not supported or implemented.
    • Network or API errors will be logged and can either stop execution or continue based on the node's "continue on fail" setting.

To resolve these, ensure valid credentials, correct property values, and stable network connectivity.
