Overview
This node is designed to generate a short key from a given long piece of information. It is useful in scenarios where you need to create a shortened representation or alias for a longer string, such as URLs, identifiers, or other data that should be referenced more compactly. A practical example would be generating a short key for a long URL to share easily or store efficiently.
Properties
| Name | Meaning |
|---|---|
| 长信息 (long_data) | The long information string to be converted into a short key. Maximum length is 4KB. |
| 过期秒数 (expire_seconds) | Expiration time in seconds for the generated short key. Maximum value is 2592000 (30 days). Defaults to 2592000. |
Output
The output JSON contains the result of the short key generation process. Typically, it will include the generated short key and possibly metadata such as expiration details. The exact structure depends on the implementation of the called operation but generally provides the short key corresponding to the input long data.
No binary data output is indicated by the source code.
Dependencies
- Requires an API key credential for authentication with the external service handling the short key generation.
- No explicit external libraries are shown beyond standard n8n workflow utilities.
- The node dynamically loads resource and operation modules from its internal directory structure, so proper module files must be present for the "其他" resource and "生成短Key" operation.
Troubleshooting
- Common issues:
- Missing or invalid API credentials can cause authentication failures.
- Input exceeding 4KB for the long information may lead to errors or truncation.
- Setting expiration seconds above 2592000 (30 days) might be rejected by the service.
- Error messages:
- "未实现方法" (Unimplemented method): Indicates the requested resource-operation combination is not implemented or the module file is missing.
- Errors during execution will be logged with detailed stack traces if debugging is enabled.
- To resolve errors, verify credentials, ensure input constraints are met, and confirm that the resource and operation modules exist and are correctly loaded.
Links and References
- No direct external links are provided in the source code.
- For further details, consult the documentation of the external service used for short key generation or the n8n community forums for similar node implementations.
