跨域，批量注册服务

1.starup.cs

services.AddCors(m => m.AddPolicy("any", a => a.AllowAnyOrigin().AllowAnyOrigin().AllowAnyHeader()));

services.BatchRegisterService(new Assembly[] { Assembly.GetExecutingAssembly(), Assembly.Load("xxx.Pay.Service") }, typeof(IDependency));

services.BatchRegisterService(new Assembly[] { Assembly.GetExecutingAssembly(), Assembly.Load("xxx.Pay.DAL") }, typeof(IBusinessDAL));

2.ServiceRegisterProvider.cs

namespace xxx.Pay.Service
{
public static class ServiceRegisterProvider
{
/// <summary>
/// 批量注册服务
/// </summary>
/// <param name="services">DI服务</param>
/// <param name="assemblys">需要批量注册的程序集集合</param>
/// <param name="baseType">基础类/接口</param>
/// <param name="serviceLifetime">服务生命周期</param>
/// <returns></returns>
public static IServiceCollection BatchRegisterService(this IServiceCollection services, Assembly[] assemblys, Type baseType, ServiceLifetime serviceLifetime = ServiceLifetime.Scoped)
{
List<Type> typeList = new List<Type>(); //所有符合注册条件的类集合
foreach (var assembly in assemblys)
{
//筛选当前程序集下符合条件的类
var types = assembly.GetTypes().Where(t => !t.IsInterface && !t.IsSealed && !t.IsAbstract && baseType.IsAssignableFrom(t));
if (types != null && types.Count() > 0)
typeList.AddRange(types);
}
if (typeList.Count() == 0)
return services;

var typeDic = new Dictionary<Type, Type[]>(); //待注册集合
foreach (var type in typeList)
{
var interfaces = type.GetInterfaces(); //获取接口
typeDic.Add(type, interfaces);
}
if (typeDic.Keys.Count() > 0)
{
foreach (var instanceType in typeDic.Keys)
{
foreach (var interfaceType in typeDic[instanceType])
{
//根据指定的生命周期进行注册
switch (serviceLifetime)
{
case ServiceLifetime.Scoped:
services.AddScoped(interfaceType, instanceType);
break;
case ServiceLifetime.Singleton:
services.AddSingleton(interfaceType, instanceType);
break;
case ServiceLifetime.Transient:
services.AddTransient(interfaceType, instanceType);
break;
}
}
}
}
return services;
}

}
}

3.controller

//提高性能
foreach (var dal in dals)
{
switch (dal.GetType())
{
case var d when d == typeof(SysUserDAL): this.userDAL = dal as SysUserDAL; break;
case var d when d == typeof(MerchantDAL): this.merchantDAL = dal as MerchantDAL; break;
}
}
