Overview
The node named "glmVideo Node" is designed to interact with video-related resources, specifically supporting operations such as retrieving video details. In the context of the "视频生成" (video generation) resource and the "视频详情" (video details) operation, this node fetches detailed information about a specific video by its identifier.
This node is beneficial in workflows where you need to programmatically access metadata or detailed information about videos, for example:
- Retrieving video metadata for display or processing.
- Integrating video details into content management systems.
- Automating video cataloging or reporting tasks.
Properties
| Name | Meaning |
|---|---|
| id | The unique identifier of the video whose details are to be retrieved. This is a required string input. |
Output
The node outputs JSON data containing the detailed information of the requested video. Each output item corresponds to one input item and includes the video details fetched from the external service.
If an error occurs during the retrieval for any item, the node can either stop execution or continue depending on the configuration, returning an error object with the message for that particular item.
No binary data output is indicated in the source code.
Dependencies
- Requires an API key credential for authentication with the external video service.
- Depends on an external plugin or resource factory (
ResourceFactory) that provides the implementation of the actual API call for the video details operation. - The node uses n8n's standard helper methods for input/output handling and error management.
Troubleshooting
Common issues:
- Missing or invalid video ID: Since the
idproperty is required, omitting it or providing an incorrect ID will likely cause errors. - Authentication failures: If the API key credential is missing or invalid, the node will fail to retrieve video details.
- Unsupported resource or operation: If the resource or operation is not implemented or incorrectly specified, the node throws an error indicating the method is not implemented.
- Missing or invalid video ID: Since the
Error messages:
"未实现方法: 视频生成.视频详情"(Method not implemented): Indicates the requested resource-operation combination is not supported.- Errors returned from the external API will be captured and can be output per item if "Continue On Fail" is enabled.
To resolve these issues:
- Ensure the
idproperty is correctly set. - Verify that the API key credential is configured properly.
- Confirm that the resource and operation names match those supported by the node.
