The configurations of WeChat mini-programs, official accounts, WeChat payments, and open platforms are all written here. If you need configurations such as enterprise WeChat, you can modify the code according to your own business.

• We just need new A service class can use the methods inside

public function createWeChatCode()
{
    $code = (new WeChatService)->createCode();
    $this->success('生成小程序码成功', $code);
