Overview
This node is designed to interact with the Wechat Work platform, specifically for managing media files. The "上传临时素材" (Upload Temporary Media) operation allows users to upload temporary media files such as images, voice recordings, videos, or general files to Wechat Work. This is useful in scenarios where you need to send or share media content temporarily within the Wechat Work environment, for example, uploading an image to be sent in a message or sharing a video clip during a conversation.
Practical examples include:
- Uploading a company logo image to be used in automated messages.
- Sending voice notes or audio clips as part of customer support workflows.
- Sharing video tutorials or presentations temporarily within team chats.
- Uploading documents or files that are needed only briefly and do not require permanent storage.
Properties
| Name | Meaning |
|---|---|
| 媒体文件类型 | The type of media file to upload. Options: 图片 (image), 语音 (voice), 视频 (video), 普通文件 (file) |
| 文件 | The name of the input field containing the binary data of the file to upload. |
- 媒体文件类型 determines the category of the media being uploaded, which affects how Wechat Work processes and stores the file.
- 文件 specifies which binary input field from the incoming data contains the actual file data to be uploaded.
Output
The node outputs JSON data representing the result of the upload operation. Typically, this includes metadata about the uploaded media such as its media ID, type, and possibly expiration information since the media is temporary.
If the node supports binary data output, it would represent the uploaded media or related binary content; however, based on the provided code and properties, the main output is JSON metadata confirming the upload success and details.
Dependencies
- Requires an API key credential for authenticating with the Wechat Work API.
- Needs network access to the Wechat Work API endpoints.
- The node depends on n8n's internal helper methods for making HTTP requests and handling binary data.
- No additional external libraries beyond those bundled with n8n and the node itself.
Troubleshooting
Common issues:
- Incorrect or expired API credentials will cause authentication failures.
- Specifying an incorrect input field name for the binary data will result in missing file data errors.
- Uploading unsupported file types or exceeding size limits imposed by Wechat Work may cause errors.
Error messages:
"未实现方法"("Method not implemented"): Indicates the requested resource-operation combination is not supported.- Network or authentication errors typically indicate invalid credentials or connectivity problems.
- Errors related to binary data usually mean the specified input field does not contain valid binary content.
Resolutions:
- Verify API credentials and permissions.
- Ensure the binary input field name matches exactly the field containing the file data.
- Check file size and type against Wechat Work's requirements.
- Use the node's "continue on fail" option to handle errors gracefully in workflows.
