Summary of WEBAPI2 knowledge points

1. We recommend async task<> with Async interface

 Public Async Task<ihttpactionresult> Get ()

If the return is IEnumerable, use:

return ok<ienumerable<listsitesdetails>> (sites);

If the return is an entity, use:

return OK (entity);

This return is often used when getting a type value:

 Public Async Task<ihttpactionresult> Get (int ID)

If you only return a successful result 200 is direct OK (); all right.

If you want to return an entity class and want to return an address route, use:

return Createdatroute ("defaultapi"new {controller="Home" 
Go to Api/home/id and return the new content that you just added sites

return Created ("http://www.*.com", sites);
Return to sites and location

2, in the Webapi How to customize the method? How do I invoke a method?

 Public Async Task<ihttpactionresult> gettest (string account ) {     stringawait Userlogin (" 15 Li Yuan Secondary school ""0000")      ; return Ok (restmsg);}

If it is a get access, all methods are preceded by a get; Post is added post, but when called, remove Get/post

such as the above code to call it to do this:/api/users/test?account=james

Of course you can also add routes to change access methods:

[Route ("api/users/gettest/{account}")]  Public Async Task<ihttpactionresult> gettest (string account ) {     stringawait Userlogin (" 15 Li Yuan Secondary school ""0000")      ; return Ok (restmsg);}

The above to invoke is used:/api/users/test/james mode

-------------------------------------------------------------------------------------

Look again at the post example

 Public Async Task<ihttpactionresult> postlogin (string School)

This representation is a post access call, which is called:/api/users/login?school= 15 miles Middle School

If you have more than one parameter, it is recommended to use type pass-through instead of string. Like what:

 Public Async Task<ihttpactionresult> postlogin (Item)

 Public class item{   publicstring school{get;  Set;}     Public string account{get;  Set;}     Public string password{get;  Set;}}

Call:

var item = {' School ': ' 15 Li Yuan Middle school ', ' account ': ' James ', ' Password ': ' 0000 '}; return $http ({    ' api/user/login ',    ' POST '    , ' Application/json ',    data: Item}). Then (function  (user) {    //  Check the user was null or not and take AC tion}). Error (function  (error) {    alert (' invalid ');});
