Overview
The node named "跃问" with the operation "绘图" (drawing or image generation) appears to be designed for generating images based on textual prompts. Users provide a description or prompt, and the node processes this input to produce an image output. This kind of node is beneficial in scenarios such as creative content generation, marketing material creation, or any workflow requiring automated image synthesis from text descriptions.
For example, a user might input the prompt "一只可爱的猫吃恐龙" ("a cute cat eating a dinosaur") to generate a corresponding image. This can be used in storytelling, design mockups, or social media content automation.
Properties
| Name | Meaning |
|---|---|
| 模型 (assistantId) | The model or intelligent agent used for processing. Placeholder suggests it can be arbitrary if unknown. |
| 提示 (prompt) | The textual prompt describing what image to generate, e.g., "a cute cat eating a dinosaur". |
| 暂不支持 (notice) | A notice field shown only for certain resources and operations indicating unsupported features. |
| 语音列表 (voice) | A required selection of voice options for text-to-speech features (not applicable for 绘图 operation). Includes official voices and cloned voices. |
Note: The "语音列表" property is shown only when text-to-speech is enabled and not for the 绘图 operation.
Output
The source code does not explicitly define the output structure within the provided snippet. However, given the operation is "绘图" (image generation), the typical output would include:
- A JSON field containing metadata about the generated image(s), such as URLs or base64 encoded data.
- Possibly binary data representing the generated image file(s).
Since the bundled code delegates execution to an external router (a.router.call(this)), the exact output format depends on that implementation, which is not included here. Generally, users can expect the node to output the generated image data or links to the images created from the prompt.
Dependencies
- The node relies on an external routing module (
./actions/router) to handle the main execution logic. - It also imports version description metadata from
./actions/versionDescription. - For voice-related properties (not relevant to 绘图), it uses a method to fetch a list of available voices.
- No direct API keys or credentials are visible in the provided code; however, the node likely requires appropriate API authentication configured in n8n to access the underlying image generation service.
Troubleshooting
- Common issues:
- Missing or empty prompt input may cause the node to fail or return no image.
- Incorrect or unsupported model identifiers could lead to errors or default fallback behavior.
- If the external router module is misconfigured or unavailable, the node will not execute properly.
- Error messages:
- Errors related to missing prompt or invalid parameters should be checked by ensuring all required fields are filled correctly.
- Network or authentication errors may occur if API credentials are not set up properly in n8n.
- To resolve issues, verify input properties, ensure API credentials are configured, and check connectivity to the external services used by the router.
Links and References
- No direct external links are provided in the source code.
- For more information on configuring image generation nodes in n8n, consult the official n8n documentation or community forums.
- Voice list references suggest integration with text-to-speech services, which may have their own documentation if TTS is enabled.
