Translation routing of ASP. NET Web API

Original: Routing in ASP Web API

When we create a new Web API project, a default route is defined in WebApiConfig.cs under the app_start folder:

            CONFIG. Routes.maphttproute (                "defaultapi",                "api/{ Controller}/{id}",                new {id = routeparameter.optional}            );

The "API" is added to the default route to avoid routing conflicts with ASP. Of course, if you don't like the convention, you can modify the default route.

Route matching rule: {controller} and {ID} skipped, only description of action match.

The 1.WEB API first looks for an action named for the HTTP method name that starts with the HTTP method name. Example:

 Public class productscontroller:apicontroller{    publicvoid  getallproducts () {}      Public Ienumerable<product> Getproductbyid (int  ID) {}    public Httpresponsemessage deleteproduct (int  ID) {}}

2. However, the above conventions apply only to get, POST, put, and delete methods. The other HTTP methods can be matched using Acceptverbs attribute, and the previous four methods also apply. Example:

 public  class   productscontroller:apicontroller{[HttpGet]  p Ublic   Product findproduct (ID) {}}  

 public  class   productscontroller:apicontroller{[Acceptverbs (  " get  , "  head   )]    Product findproduct (id) {}  //   WebDAV method  [Acceptverbs ( " Span style= "color: #800000;" >mkcol   )]  public  void   Makecollection () {}} 

3. Match by Action name (rewrite route). Example:

routes. Maphttproute (    "actionapi",    "api/{controller}/{ Action}/{id}",    new {id = routeparameter.optional});

3.1. The GET request according to the above routing rule "api/products/details/1" will match:

 Public class productscontroller:apicontroller{    [httpget]    publicstring Details (int  ID);}

3.2. You can use ActionName attribute to override the action name. Example:

 Public class productscontroller:apicontroller{    [HttpGet]    [ActionName ("Thumbnail"  )]    public httpresponsemessage getthumbnailimage (int  ID);    [HttpPost]    [ActionName ("Thumbnail")]      Public void Addthumbnailimage (int  ID);}

This "api/products/thumbnail/ID" has two matches, corresponding to get and post respectively.

4. If a method does not want to be invoked as an action, you can use Nonaction attribute, for example:

// Not an action method. [nonaction]    Public string GetPrivateData () {...}
