This guide explains how to create custom QR code with Java REST API. It will teach you to develop a custom QR code generator with Java Low Code API using a Java-based Cloud SDK. All the necessary parameters will be discussed and demonstrated to understand the QR code customizations and storage as an image on the disk.
Prerequisite
- Create an account and get API credentials for generating custom QR codes
- Download Aspose.BarCode Cloud SDK for Java to personalize QR codes
- Set up a Java project with the above SDK
Steps to Make Custom QR Code with Java REST Interface
- Start by adding the using lines so your program knows about the Aspose.BarCode Cloud classes
- Create a configuration object and give it the base API address, your client ID, and your client secret
- Make a GenerateApi object from your configuration so you can send barcode requests
- Set up the data you want to encode — in this case, a QR code containing a web link
- Pick colors, image type, rotation, resolution, and size for the barcode image
- Run the GenerateBodyAsync method with your settings to build the barcode image
- Open a new file stream called output.png to hold the generated image
- Copy the data from the generated barcode into your file so it’s saved on your computer
These steps outline the process for developing a custom QR generator using Java RESTful Service. First, connect your app to Aspose.BarCode Cloud by importing the right classes, setting up the configuration, and creating a GenerateApi object. Then you provide the QR code data, customize its look, generate the barcode, and save the resulting image as output.png on your computer.
Code to Customize a QR Code with Java-based API
The above code demonstrates the process to create custom barcode with Java REST API. BarcodeImageParams is basically the part where you decide how your barcode picture should look. You can choose its colors, size, sharpness, format, and even rotate it so it matches the style you want for printing or displaying.
This short tutorial has explained how to make your own QR code generator with Java REST Interface. To generate a QR code, refer to the article on Scan QR code with Java REST API.
