有人对我说 " 针对于mvc的设计 model层不应该进行任何的抛错等操作。这些操作应该由c来完成。"
是这样的吗? M层为什么不能抛出异常? 我无法理解
回复讨论(解决方案)
这并没有一定的规则
但他说的也有些道理,model 是业务逻辑,如果 model 也有异常的话,那整个流程都是错误的了
当然他说的是:当 model 出现异常的时候,只抛出,不处理。处理交给 Controller
控制层调用model业务逻辑返回值,做相应的抛出异常。
这话太绝对了。这种东西没有标准。M 层也可以抛出异常。

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.
