Hi,

I see the thread's title and the question have the different meanings.

we are in the process of define a REST API for our application , do the EXT.NET compatible with REST , i mean the STORE object.

Please see

im building a REST Service using MVC 3.0 where each resource will have a get, post,delete,put action method and i need to know if EXT store can resolve such calls, since all example here is about Ws.* web services REST which is calling web services using WS and return JSON,my action methods will receive a http request of type get,post,delete,put only

my question is do ext.net store can resolve this and how, and if you provide me an example i will greatfull.

HttpProxy has RestAPI property

<RestAPI CreateUrl="/User/Create" CreateMethod="POST"  />

Suppose i have following MVC 3 REST API Action Method:

[HttpGet]
        [ActionName("List")]
        public ActionResult PageInsightsGet(string Uniqueid)
        {
            ActionResult actionResult=null;
            try
            {
                switch (int.Parse(Request.QueryString["Query"]))
                { 
                    case 1:
                         Paging<FacebookStatistics> JsonObject = new Paging<FacebookStatistics>(new List<FacebookStatistics>(), 0);
                         List<FacebookStatistics> results = FacebookUtility.RetrievStoredInsights(Uniqueid, Request.QueryString["QueryType"]);
                        JsonObject = new Paging<FacebookStatistics>(results, results.Count);
                        actionResult = this.View("", JsonObject);
                        break;
                    case 2:
                        break;
                    case 3:
                        break;
                
                }
            }
            catch (Exception ex)
            {
                actionResult = this.View("", new ErrorDetail { Description = ex.Message, DebugInformation = ex.StackTrace }, HttpStatusCode.BadRequest);
            }
           
            return actionResult;
        }

i open chrome and hit the service using following url:
http://localhost:9265/FacebookInsigh...t=json&query=1

and the return JSON is :

{"Data":[{"FacebookFans":"49","NewFans":"0","NewFansPercentage":"0.0","Visits":"0","VisitsPercentage":"0.0","PageViews":"6","UniqueVisitors":"2","uniqueid":"201118776571940","MembersImagespath":"Images/DashBoardNewLook/equal.png","pageviewsImagespath":"Images/DashBoardNewLook/equal.png","MembersColor":"Yellow","PageViewsColor":"Yellow","PageLikesAdd":"0","PageComments":"1","PageCommentspercentage":"0.0","PageCommentaddImagePath":"Images/DashBoardNewLook/equal.png","PageCommentaddColor":"Yellow","PageFanAdds":"0","PageFansRemoves":"0","PageStreamViews":"141","PageVideos":"0","PageVideosPlays":"0","PageViewsLogin":"6","PageViewsLogout":"0","PageWallPosts":"0"}],"TotalRecords":1}

which is cool , but i need an example how to call this REST Service using a Ext:Store, where i can pass parameters and query strings if possible.

if you wonder how i did the JSON directly im aleardy build a frawework which intrrupt the ActionResult and depends on the query string Format i render the result .

Your urgent help is appreciated.

i create ASPX file and add following store:

<ext:Store ID="FacebookInsightsStore" runat="server" ShowWarningOnFailure="false" Restful="true">
        <Proxy>
            <ext:HttpProxy DisableCaching="true" Json="true" AutoDataBind="true">
             <RestAPI AutoDataBind="true"
                ReadMethod="GET" />
            </ext:HttpProxy>
        </Proxy>
        <Reader>
            <ext:JsonReader Root="d.Data" TotalProperty="d.TotalRecords">
                <Fields>
                    <ext:RecordField Name="FacebookFans" />
                    <ext:RecordField Name="NewFans" />
                    <ext:RecordField Name="NewFansPercentage" />
                    <ext:RecordField Name="Visits" />
                    <ext:RecordField Name="VisitsPercentage" />
                    <ext:RecordField Name="PageViews" />
                    <ext:RecordField Name="UniqueVisitors" />
                    <ext:RecordField Name="uniqueid" />
                    <ext:RecordField Name="MembersImagespath" />
                    <ext:RecordField Name="pageviewsImagespath" />
                    <ext:RecordField Name="MembersColor" />
                    <ext:RecordField Name="PageViewsColor" />
                    <ext:RecordField Name="PageComments" />
                    <ext:RecordField Name="PageCommentspercentage" />
                    <ext:RecordField Name="PageCommentaddImagePath" />
                    <ext:RecordField Name="PageCommentaddColor" />
                    <ext:RecordField Name="PageFanAdds" />
                    <ext:RecordField Name="PageFansRemoves" />
                    <ext:RecordField Name="PageLikesAdd" />
                    <ext:RecordField Name="PageStreamViews" />
                    <ext:RecordField Name="PageVideos" />
                    <ext:RecordField Name="PageVideosPlays" />
                    <ext:RecordField Name="PageViewsLogin" />
                    <ext:RecordField Name="PageViewsLogout" />
                    <ext:RecordField Name="PageWallPosts" />
                </Fields>
            </ext:JsonReader>
        </Reader>
        <Listeners>
            <BeforeLoad Handler="this.loading=false;" />
            <LoadException Handler="if (response.responseText=='{&quot;d&quot;:null}') { alert('Grid is  empty!'); }" />
            <Load Handler="this.loading=false;" />
        </Listeners>
    </ext:Store>

and add following code to the code behind:

  (FacebookInsightsStore.Proxy.Proxy as HttpProxy).Url = "http://facebookapi";
            (FacebookInsightsStore.Proxy.Proxy as HttpProxy).RestAPI.ReadUrl = "/FacebookInsights/201118776571940?format=json&Query=1";

The problem is the EXT.NET generate following url which i sniffer from fiddler:

http://localhost/FacebookInsights/201118776571940?format=json&Query=1&_dc=1313536698930

how i can inform the store that the service is not include under the website , which the case i will have , where i will create a separeted website or virtual directory under IIS which host the service , your urgent help really need , i feel im almost there but i need a little help.

[Vladimir]

HttpProxy cannot perform cross domain requests (it is limitation of ajax request of the browser), ajax request can work with same domain only

[farisqadadeh]

thanks Vladimir,

even when i use a virtual directory under my site(same domain) , the problem still appear where the generating url still wrong:

The code:

          (FacebookInsightsStore.Proxy.Proxy as HttpProxy).Url = "http://localhost/FaceBookAPI";
          (FacebookInsightsStore.Proxy.Proxy as HttpProxy).RestAPI.ReadUrl = "/FacebookInsights/201118776571940?format=json&Query=1";

The URL:

http://localhost:9265/FacebookInsights/201118776571940?format=json&query=1

do i have to set additional parameters or store option.

also i wana share with you a thread from sencha site forum:
http://www.sencha.com/forum/showthre...ata.Connection
http://www.java2s.com/Code/JavaScrip...remotedata.htm

cant you employ the concept to EXT.NET.

also i wonder how facebook developers build an Javascript SDK to call their Graph API which is hosted on a separated domain of https://graph.facebook.com


your urgent help really appreciated.

[Vladimir]

For two documents to be considered to have the same origin, the protocol (http/https), the domain and the port (the default 80 or :xx) have to be indentical. So, you cannot use ajax request against a different port also.

And ReadUrl is not mixed with Url property

[farisqadadeh]

i will try this and update you , but im really wonder about following:
