[Web API series tutorial] 3.1-practice: process data (create a project)Preface
This guide will teach you basic skills for creating Web applications on the backend using ASP. NET web APIs. This Guide uses Entity Framework 6 as the data layer and knockout. js as the client's JavaScript Application. This Guide also shows

Once the API is released, the consumer will start to use it and mix it with other data. However, changes are inevitable when new requirements arise. You may be glad that the API changes have not been affected on the existing client, but this situation will not happen all the time.
Therefore, it is necessary to carefully consider the Version Policy of ASP. NET
Http://www.cnblogs.com/UliiAn/p/5402146.htmlIn the Web API, the idea of aspect-oriented programming (AOP) is introduced, in which specific filter can be inserted for process interception processing. The introduction of this mechanism can better practice the dry (Don ' t Repeat yourself) thought, through the filter can be unified to some common logic processing, such as: Permission check, parameter and decryption, parameter verification, etc. we can us
http.ResponseWriter, req *http.Request) {
mutex.Lock()
fmt.Fprintf(res, "Visit Count: %d\n", count)
mutex.Unlock()
} This time, we introduced the sync package to deal with the data update problems caused by concurrent access, sync.Mutex and the classes provided Lock() and Unlock() methods to lock and unlock update operations, and ensure that count incremental operations were not affected by concurrent access. Run the above code, and then access the path in the browser except /count
The purpose of this series is to pour out the dry goods accumulated over the last two years in the practice of Web APIs and share them with you. It is also welcome to discuss communication with a friend who is using the Web API or who intends to use the Web API in the project, so that I have enough enthusiasm to comple

We also provide an example: Public classErrorhandler:exceptionhandler { Public Override AsyncTask Handleasync (exceptionhandlercontext context, CancellationToken CancellationToken) {if(Context.

The development efficiency of the rails framework is fully demonstrated.PostScriptBecause it was the first rails program, we didn't need to delve into Ruby's syntax details on rails, and we used the build tool provided by rails to quickly generate applications that contained databases, which is much faster than other development frameworks, scaffold.
