将WebAPI添加到现有的MVC5应用程序

Question

I have an MVC5 application, which works normally. It has models, controllers, views, and all the other functionality. It is already a stand-alone app. I now want to create an API for this application. I don't know whether I should create a new WebAPI project in the same solution, or use my existing MVC project, to also include the API functionality there. Which is the appropriate way? Please note that later I want to use that API for creating a mobile application using Xamarin.

Answer 1

There is nothing wrong with using the same project, in many ways it makes the most sense as it will be easier when hosting the application if they live within the same web project.

I tend to keep my API controllers in a subfolder called "Api" which is neatly located within the Controllers folder of the web solution.

"Controllers > Api".

When i'm not sure with these kinds of things I tend to go with the simplest option, later on down the line if you find a good reason to locate the controllers in their own project for some reason this is easily achieved.

You mentioned that you will be using the API to develop an application using XAMARIN later on and this should not mean moving the API... mobile apps will not need any kind of reference to the API at all, they will simply be calling your application using standard HTTP requests. It will make no difference and again as you are going to need a host for your website, you might as well use the same host for your API too.

如果您不仅要对WebSite使用WebAPI可以肯定的是，您已经在解决方案中添加了新的WebAPI项目（+在OOP更好）-更改很容易。
