Someone should have noticed that the blogger added a Do You Like Me widget to the sidebar. In fact, I think the easier way is to use PHP+SQL+AJAX , but in the idea of tossing + reducing costs (white prostitution) , using Vercel , LeandCloud and Node.JS to roll one out.
Node version
Since Node.Js is in a semi-entry state, the code quality is not high, but the program runs in a strange way after all.
Project address: https://github.com/5ime/likeMe
PHP version
Since I am hosted by vercel do not have permission to创建or修改files, I will request LeanCloud every time I get the number of like , resulting in a high number of requests, so I created a PHP version and wrote the number of like into the count.dat file. , read count.dat when requested and update count.dat after clicking. The following code can be uploaded to your own server.
composer install dependencies

composer require leancloud/leancloud-sdk
