I have a few questions:
1 Shouldn’t $user, the automatically loaded construct, be empty?
is to call $this->user->name in the hello method, so what you get is also empty.
Why is it written like this?
The parameter of the constructor method is required to be a userModel object. If this object has the attribute name, it can be $this->user->name.
An error will be reported. In the construction method, did you pass user in the new object (did you pass it in)?
