Overview
This node provides utilities to generate and decode QR codes as part of a broader "Generate" resource. Specifically, the "QR Code" operation supports two main functions:
- Encoding arbitrary data into a QR code image.
- Decoding data from an existing QR code image URL.
Common scenarios include:
- Creating QR codes for URLs, text, or other data to share easily via print or digital media.
- Reading and extracting information from QR codes found in images or online resources.
Practical examples:
- Encode a product URL into a QR code to print on packaging.
- Decode a QR code image URL received from a customer to retrieve embedded information.
Properties
| Name | Meaning |
|---|---|
| Operation | Choose between encoding data into a QR code or decoding a QR code image. Options: "Encode Data to Qr Code", "Decode a Qr Code". |
| Data You Want to Encode | The string data that you want to convert into a QR code (required when encoding). |
| URL to QR Code Image | The URL pointing to the QR code image you want to decode (required when decoding). |
| Code Variables | A collection of variables defined in the code editor that can be used within the code execution context (advanced usage). |
Output
The node outputs JSON data representing the result of the QR code operation:
- For encoding, the output typically includes the generated QR code image data or a URL to the QR code image.
- For decoding, the output contains the decoded data extracted from the provided QR code image URL.
If binary data is involved (e.g., QR code images), it will be represented accordingly, but this node primarily deals with JSON output containing encoded or decoded information.
Dependencies
- Requires an API key credential for authentication with the external service providing the QR code generation and decoding functionality.
- The node relies on an external API endpoint under the "generate/qrcode/encode" or "generate/qrcode/decode" paths.
- No additional environment variables are explicitly required beyond the API key credential.
Troubleshooting
- Invalid or missing data: When encoding, ensure the "Data You Want to Encode" property is not empty; otherwise, the API may return an error.
- Invalid URL for decoding: When decoding, verify that the "URL to QR Code Image" points to a valid and accessible QR code image.
- API authentication errors: Make sure the API key credential is correctly configured and has the necessary permissions.
- Network issues: Connectivity problems to the external API can cause failures; check network access and proxy settings if applicable.
- Unexpected response format: If the API changes its response structure, the node might fail to parse results properly.
