angularjs--Custom Service Provider $get

providerThere are three parts that can be thought of:

The first part is private variables and private functions, and these variables and functions are modified later.

The second part is the app.config variables and functions that can be accessed in the function, so they can be modified before being used elsewhere. Note that these variables and functions must be added to the this above line.

The third part is the variables and functions that can be accessed in the controller, which is returned by the $get function.

　　When using provider the Create service, the only properties and methods that can be accessed by the controller are the $get() properties and methods returned in the function.
