This is a terrible China Mobile trap. Everyone must be careful. Last, the IP discount is not applicable to roaming. This is not true. I tried it. Adding 17951 during roaming is only 0.39 RMB/minute. ---------------------------- Preface: If you have a pair of guns, this article is worth reading and you are also welcome to comment.

I. Strategy ModeThe rule mode is intended for a group of algorithms,Encapsulate each algorithm into an independent class with a common interfaceSo that they can be replaced with each other. The policy mode allows the algorithm to change without affecting the client. Suppose we want to design a shopping cart CAT System for e-commerce websites selling books. The simplest case is to multiply the unit price of all goods by the quantity, but the actual situation must be more complicated than that. Fo

The rule mode is intended for a group Algorithm , Encapsulate each algorithm into an independent class with a common interface, so that they can be replaced with each other.

The simplest case is to multiply the unit price of all goods by the quantity, but the actual situation must be more complicated than that. For example,

The desired effect is to achieve 90 percent or 80 percent of the total price of all items in the cart:When you click on "90 percent":When you click on "80 percent":-Ideas80 percent or 90 percent is the different implementation of the discounted interface, the key is: what conditions to decide which discount method to use?--When you click on the 80 percent or 90 percent link, put the parameters in the route, and then in the custom controller factory, d
