问题描述
如何通过字符串名称在另一个AppService中调用API?
How to call an API in another AppService by string name?
示例:我在MyAppService中具有如下所示的API
Example: I have an API as below in MyAppService
public class MyAppService : MyAppServiceBase, IMyAppService
{
private readonly IRepository<MyEntity> _myEntityRepository;
public CommonLookupAppService(IRepository<MyEntity> myEntityRepository)
{
_myEntityRepository = myEntityRepository;
}
public async Task<MyOutput> MyMethod (MyInput input)
{
}
}
如何将MyMethod
作为字符串保存到数据库中并在另一个应用程序服务中调用它?我有很多这样的方法,所以我不想使用switch case
来调用它们.我想将此方法程序集名称作为字符串保存到数据库中,并在需要时调用它.我该怎么办?
How to save MyMethod
as a string into the database and invoke it in another app service? I have many methods like this so I don't want to use switch case
to call them. I want to save this method assembly name to the database as a string and invoke it when needed. What should I do?
推荐答案
您可以使用以下组合:
-
Type.GetType(string)
-
Type.GetMethod(string)
-
IIocResolver.ResolveAsDisposable(Type)
—通过ABP -
MethodInfo.Invoke(Object, Object[])
Type.GetType(string)
Type.GetMethod(string)
IIocResolver.ResolveAsDisposable(Type)
— by ABPMethodInfo.Invoke(Object, Object[])
// var appServiceName = "MyAppService";
// var methodName = "MyMethod";
// var input = new object[] { new MyInput() };
var appServiceType = Type.GetType(appServiceName);
var method = appServiceType.GetMethod(methodName);
using (var appService = IocResolver.ResolveAsDisposable(appServiceType))
{
var output = await (Task)method.Invoke(appService.Object, input);
}
