2. NETCORE
is a brand of Ethernet Broadband Router and switch. This is not a network. As for security, it's hard to say. I use Huawei and CITIC

3. Leko, router

4. If you don't have a wireless router in your home, it must be someone else's
ha ha~

5. The computer router is wireless.. The other party knows a little bit that there is a person in the joint. Generally no harm... Your mobile phone doesn't have what Alipay account or Taobao.

net standard library is the core of. Net core portability

net standard is a standard Net core is an implementation of this standard (in addition, there are. Net framework, mono, etc.)

8. Yes, but very few. It hasn't been applied on a large scale yet. Net core is developing very fast. I believe it will soon be available.

9. If you are familiar with the. Net platform, have a stable job, and don't want to study new technologies, then. Net is a good choice for you. If you are a junior programmer or just joined the. Net platform, if you are in a small company and are not satisfied with the status quo, if you want to get better job opportunities, then. Net core is definitely worth a try; This unified platform will certainly occupy a large part of Microsoft's territory in the future. Microsoft has unified PC and mobile phone systems with windows 10, and announced that this is the ultimate operating system, and will no longer launch windows 11; The open source and more unified. Net core will definitely have a larger application scenario. Therefore, it must be. Net core

10. What we call application builder is a general term for all types and objects that implement iapplicationbuilder interface. The startup type registered to webhostbuilder has a configure method for pipeline setting, which uses the application builder object as a parameter to register the middleware. Since application builder has a direct relationship with the middleware that makes up the pipeline, we have to talk about what kind of object middleware is embodied in the pipeline. Middleware is embodied as a delegate object of type func in the request processing process. For many readers who have just contacted the request processing pipeline, it may be a little difficult to understand at first, so let's give a brief explanation. We have mentioned a delegate like requestdelegate, which is equivalent to a func object. The delegate object represents a processing operation for the provided httpcontext, which represents the processing of requests by a middleware. So why don't we use a requestdelegate object to represent a middleware directly, but a func object instead? In most applications, we will register many different middleware according to the specific request processing requirements. These middleware are arranged according to the order of registration time to form the so-called request processing pipeline. For a middleware, after it completes its request processing task, it needs to pass the request to the next middleware for subsequent processing. The requestdelegate object in func, as an input parameter, represents a delegation chain, which reflects the subsequent middleware's processing of requests. The current middleware adds its own request processing tasks to the delegation chain, and the returned requestdelegate object represents the latest delegation chain. Taking the pipeline shown in the right figure as an example, if a func is used to represent middleware B, then the requestdelegate object as the input parameter represents the processing operation of C on the request, and the return value represents the processing operation of B and C on the request successively. If a func represents the first middleware to receive requests from the server (such as a), then the requestdelegate returned by executing the delegate object actually reflects the whole pipeline's processing of requests. With a good understanding of middleware, let's take a look at the definition of the iapplicationbuilder interface used to register middleware. The following is the definition of the trimmed iapplicationbuilder interface. We only reserve two core methods. The use method implements the registration of middleware, and the other build method transforms all registered middleware into a requestdelegate object. 1::{3:RequestDelegateBuild(); 4:IApplicationBuilderUse(Funcmiddleware); 5: Considering the convenience of programming, many predefined middleware have extension methods for registration. For example, we call the extension method usestaticfiles to register the middleware for processing static file requests. For the image publishing application we demonstrate, it also registers the middleware for processing image requests by calling an extension method useimages with the following definition. 1::{3:(thisIApplicationBuilderapp,stringdirectory)4:{5:Funcmiddleware=next=> 6:{7:returncontext=> 8:{9:stringfileName=context.Request.Url.LocalPath.TrimStart('/&# 39;); 10:if(string.IsNullOrEmpty(Path.GetExtension(fileName)))11:{12:fileName+=". jpg"; 13:}14:fileName=Path.Combine(directory,fileName); 15:context.Response.WriteFile(fileName," image/jpg"); 16:returnnext(context); 17:}; 18:}; 19:returnapp.Use(middleware); 20: By default, asp.net core uses an object of type applicationbuilder to register middleware. We use the following code fragment to simulate its implementation logic. We use a list & gt; Object to store all registered middleware, and call the aggregate method to convert it into a requestdelegate object. 1:publicclassApplicationB uilder:IApplicationBuilder2 :{3:privateIList> middlewares=newList>(); 4:5:publicRequestDelegateBuild()6:{7:RequestDelegateseed=context=> Task.Run(()=>{}); 8:returnmiddlewares.Reverse().Aggregate(seed,(next,current)=> current(next)); 9:}10:11:publicIApplicationBuilderUse(Funcmiddleware)12:{13:middlewares.Add(middleware); 14:returnthis; 15: } 16:} ASP. Net core does not directly create an application builder object to register middleware, but uses the corresponding factory to create it. Create a factory that loves your applicationbuilder through the interface iapplicationbuilderfactory. In the simulated pipeline, we simplify this interface into the following form. The default implementer of this interface, applicationbuilderfactory, will directly create an object of type applicationbuilder. 1::{3:(); 4:}5:6::IApplicationBuilderFactory7:{8:public()9:{10:returnnewApplicationBuilder(); 11:}12:}
