7.3 请求拦截器的类型安全改造

一、拦截器类型系统架构设计

1.1 拦截器类型关系图

    class AxiosInstance {
        +interceptors: {
          request: InterceptorManager~AxiosRequestConfig~,
          response: InterceptorManager~AxiosResponse~
        }
    }
    
    class InterceptorManager~V~ {
        +use(
            onFulfilled?: (value: V) => V | Promise~V~,
            onRejected?: (error: any) => any
        ): number
        +eject(id: number): void
    }
    
    class RequestInterceptorChain {
        +success: (config: AxiosRequestConfig) => Config
