In the background development process, the validation of parameters becomes an indispensable part of the development environment. For example, the parameter can not be null,email so must conform to the format of email, if manually make if judgment or write regular expression to judge the unintended development efficiency is too slow, in time, cost, quality of the game will inevitably lag behind. So the verification layer is the inevitable result of abstraction, the following is a few solutions.T
