从我阅读的内容中得知.您正在使用参数CompanyController实例化UserController.

From what I read. You are instantiating the UserController with the parameter CompanyController.

此实例化是在您实际发送Auth :: login()调用之前完成的.

This instantiation is done before you have actually send the Auth::login() call.

当您在userController上运行confirmUser之前，用__construct实例化公司控制器时，对象CompanyController在进行Auth::login()调用之前就已经存在.

As you are instantiating the company controller with __construct before running confirmUser on the userController the object companyController exists before the Auth::login() call is made.
