In this cool Spring Boot project I've learned how to work with the ZXing library, an open-source library, to encode information and create QR codes. Request parameters include:
- Image size (max 350, min 150)
- Type(png, jpeg or gif)
- Contents - message to be encoded(must not be empty or blank)
- And four error correction levels, determining how much code can be damaged or obscured while still readable (Level L (Low), Level M (Medium), Level Q (Quartile), Level H (High)).
If there is no errors in the request, the program will generate a QRCode image.
Otherwise, the program will return a Json message, specifying the error in the request. Examples:
