The ASP. NET Web Api Returns the result format, and the display in the browser

using System.Collections.Generic; using System.Web.Http; using ExtJS.WebApi.Data; namespace extjs.webapi.controllers{    [Routeprefix ("Api/book")] public    class Bookcontroller:apicontroller    {        [Route ("Get")] public         list<bookmodel> Get ()        {            return bookrepository.list;}}    }

Using Firefox, show:

The returned "Content-type" is "Application/xml"

ExtJS 4

    Ext.regmodel (' BookInfo ',   {       ' Name ''string ' }]   });    var bookstore = ext.create (' Ext.data.JsonStore ',    {        ' BookInfo ',        proxy: {            ' ajax ',             ' Book/get ',            ' JSON ' }}}    );

...

 {xtype:  ' combo ' , Fieldlabel:  book List ' , Listconfig: {loadingtext:  ' loading book information ' , empt            Ytext: }, TriggerAction:  ' all ' , Store:bookstore, Displayfield:  "Name" , Valuefield:  "N Ame ", Querymode:  ' remote ' , querydelay:300} 

The request succeeds, and the return data is XML

The data cannot be displayed in the drop-down box

IE no problem. The requested data is data in Application/json format

But in IE, the return is "Application/json"

In order to solve Firefox, request ASP. NET WEBAPI data, get the data of XML, need to do this:

 public  class  browserjsonformatter: Jsonmediatypeformatter {public  browserjsonformatter () {this . Supportedmediatypes.add (new  mediatypeheadervalue ( "text/html"             )); this .        serializersettings.formatting = formatting.indented; } public  override  void  Setdefaultcon Tentheaders (type type, httpcontentheaders headers, Mediatypeheadervalue mediatype) { Base .            Setdefaultcontentheaders (type, headers, mediatype); Headers. ContentType = new  mediatypeheadervalue ( "Application/json" ) {        CharSet =  "UTF-8" }; }    }

\app_start\webapiconfig.cs

         Public Static void Register (httpconfiguration config)        {           ...                       Config. Formatters.add (new browserjsonformatter ());        }

Request the API again
