本文介绍了是否可以从.NET Core中间件检索控制器的动作结果?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
public class UsersController : APIControllerBase
{
public UsersController() { }
public Client Get()
{
return new Client()
{
ClientID = 1,
// LastUpdate = I want to update this field in middleware
};
}
public Client Get(int id)
{
return new Client()
{
ClientID = id
// LastUpdate = I want to update this field in middleware
};
}
}
public class SetClientLastUpdateMiddleware { private readonly RequestDelegate next; public SetClientLastUpdateMiddleware(RequestDelegate next) { this.next = next; } public async Task Invoke(HttpContext context) { await next(context); // Can I do something like below? if(context.ActionResult is Client) ((Client)context.ActionResult).LastUpdate = Date.Now; } }
请考虑以上代码.我想为每个端点应用一个处理程序.我不知道中间件是否合适.我需要获取端点的操作结果作为其原始类型并对其进行一些更新.如果中间件不是正确的方法，那么任何建议都将不胜感激.
Please consider above codes. I want to apply a handler for every endpoint. I don't know if middleware is a proper option. What I need is to get the endpoint's action result as its original type and do some update to it. If middleware is not a proper way, any advice would be appreciated.
推荐答案是.但是您不能在控制器中创建新客户端.尝试在Client中创建一个公共变量，您可以在中间件中提供该值.在您的控制器中，您可以获取该值并将其添加到该对象.
Yes. But you can't create a NEW client in your controller. Try to create a public variable in Client which you can give the value in the middleware. And in your controller you can get this value and add to this object.
