为什么人们使用MVC中的WebAPI控制器?-WhypeopleuseWebAPIcontrollerinMVC

Web API and ASP.NET MVC are two different beasts.

Web API和ASP。NET MVC是两个不同的东西。

ASP.NET MVC is used for a RPC style of app, this means that your endpoints perform arbitrary actions. So you can have a PersonController with an action called FooBar and you can call that procedure by GETting domain.com/person/foobar.

ASP。NET MVC用于RPC样式的应用程序，这意味着您的端点执行任意操作。你可以有一个叫FooBar的person控制器你可以通过获取domain.com/person/foobar来调用这个过程。

Web API is used (mostly) for REST (although is also does support RPC). This means that your controller exposes a resource that you then GET or POST or PUT or DELETE. So your PersonController in Web API will have a Get method and a Post method etc.

Web API主要用于REST(尽管也支持RPC)。这意味着您的控制器公开一个资源，然后您可以获取、发布、放置或删除该资源。所以你在Web API中的PersonController会有一个Get方法和Post方法等等。

You can declare any methods you like in an API controller class. In a 100% purely REST controller you would have methods that map to the HTTP verbs (i.e. Get, Post, Put, Delete). You can use the Web API routing mechanism to also map URLs to an action (see more here: http://encosia.com/rest-vs-rpc-in-asp-net-web-api-who-cares-it-does-both/) if you'd like too.

您可以在API控制器类中声明任何您喜欢的方法。在100%纯REST控制器中，您将拥有映射到HTTP谓词的方法(例如，Get、Post、Put、Delete)。您可以使用Web API路由机制将url映射到一个操作上(请参见此处:http://encosia.com/rest-vs-rpc-in-asp-net- Web - API -it-do -both/)，如果您也想这样做的话。

The put-function is for handling the HTTP verb PUT. So if you have a PersonController with a Put method you would in that method e.g. handle an update of a person instance.

放置函数用于处理HTTP谓词PUT。如果你有一个带有Put方法的PersonController，你会在那个方法中处理person实例的更新。

1) With a WebAPI controller you can just return json/xml, resulting in an advantage: you can use any client, not just a web browser. You also get GET ajax by default in WebAPI.

1)使用WebAPI控制器，您只需返回json/xml，就会产生一个优势:您可以使用任何客户端，而不仅仅是web浏览器。您还可以在WebAPI中默认获得ajax。

2) Are you only going to use a web browser? Use MVC. Otherwise? Use WebAPI and a web browser/whatever as a client to WebAPI.

2)你只会使用web浏览器吗?使用MVC。否则呢?使用WebAPI和web浏览器作为WebAPI的客户端。

3) returning json/xml.

3)返回json / xml。

5) Update an object.

5)更新一个对象。

6) Yes.
