This article guides on generate QR with Java REST API. You will learn to develop a QRCode generator with Java Low Code API using a Java-based Cloud SDK. Various characteristics of the output QRCode image will be shared to customize the output image file.
Prerequisite
- Create an account and get API credentials for creating a QR Code
- Download Aspose.BarCode Cloud SDK for Java to generate a QR Code in an image
- Set up a Java project with the above SDK
Steps for QR Code Builder with Java REST Interface
- Include Aspose.BarCode Cloud SDK API and model classes
- Initialize the configuration with API base URL, client ID, and client secret
- Specify the file name where the QR Code image will be saved
- Create an instance of GenerateApi using the configured settings
- Call the GenerateAsync method to create a QR Code with the desired text and image format
- Open a file stream to prepare for writing the generated QR Code image
- Copy the generated QR Code stream into the file for storage
These steps summarize the process for a 2D code generator with Java-based API. First, set up the Aspose.BarCode Cloud SDK by configuring your API credentials and choosing a file name for the QR Code. Then, generate the QR Code with your desired text and format, and save it to a file for use.
Code for QR Builder using Java RESTful Service
The above code demonstrates a QR tag generator with Java REST API. The GenerateAsync() method lets you create a barcode or QR code in the background by providing the text you want to encode and optional settings like style, size, colors, or rotation. It puts everything together into a request and gives you back the finished code as a stream you can save or use.
This article has taught us the process to create a QR code. To generate a barcode, see the article Generate barcode with Java REST API.
