Overview
This node interacts with the Wechat Official Account platform to retrieve media assets (素材). Specifically, for the "素材" resource and the "获取素材列表" operation, it fetches a list of media materials such as images, videos, voice recordings, or news articles from the user's Wechat Official Account.
Common scenarios where this node is useful include:
- Managing and displaying media content stored in a Wechat Official Account.
- Automating workflows that require fetching batches of media assets for further processing or publishing.
- Integrating Wechat media content into other systems or databases.
For example, a user might use this node to periodically fetch the latest 10 images uploaded to their Wechat Official Account to update a website gallery automatically.
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 | The offset position to start returning materials from. 0 means starting from the first item. |
| 返回数量 | The number of materials to return. Must be between 1 and 20. |
Output
The node outputs an array of JSON objects representing the media materials retrieved from the Wechat Official Account. Each item in the output corresponds to one media asset and contains its metadata and content details as provided by the Wechat API.
If the media includes binary data (e.g., images, videos, or voice files), the node may also output binary data fields containing the actual media content.
Dependencies
- Requires an API key credential for authenticating with the Wechat Official Account platform.
- The node depends on the Wechat Official Account API to fetch media materials.
- Proper configuration of the Wechat Official Account credentials within n8n is necessary.
Troubleshooting
Common issues:
- Invalid or expired API credentials can cause authentication failures.
- Requesting an offset beyond the available media count will result in empty results.
- Requesting a count outside the allowed range (1 to 20) may cause errors.
Error messages:
"未实现方法: 素材.获取素材列表"indicates that the requested resource-operation combination is not implemented; ensure correct resource and operation names.- Network or API errors will be logged and can cause the node to fail unless "Continue On Fail" is enabled.
Resolutions:
- Verify and update API credentials.
- Adjust offset and count parameters within valid ranges.
- Check network connectivity and Wechat API status.
