Today, I arranged the task to do the QR code generation task, generate different QR codes for different products of the dealer, and print them out later to cooperate with the APP record. The intention is to let him understand the zxing package of the QR code. Through java To achieve it, I didn't expect to see the progress halfway, and found an online QR code generation api to generate it directly. Haha, well, that's the easy way too.
Two-dimensional code generation is actually these two methods.
1. By calling a third-party library such as zxing to write, the advantage is to understand the principle and have strong controllability. You can directly refer to this URL, the code is very detailed http://blog.csdn.net/mmm333zzz/article/details/17259513.
2. Directly call through the api that has been published on the Internet. I have tried a few. The more useful one is the QR code for forage http://cli.im/api. If the user logs in, they can also make their own beautification templates, embed logos, different textures and other functions, and then call their own templates in the api.
