I'm trying to setup / consume a Yahoo! RESTful service that has a callback and I am running into some issues:

• Per the attached screenshot, the service test screen returns a response but is showing an error when attempting to automatically create a service response.

  

  To get around this, I manually created the Response.

  

• When invoking the service, the Success event is not triggered but the Complete event is.

  How can I setup and consume this service? Any help is appreciated. Thanks.

Hello,

You get no JSON but JSONP in reply. You should remove request parameter callbackand and put in the configuration Data Type=JSONP Here you may find more info:

Hi, Evgene. Thank you for your reply. If I specify JSONP as the data type, then the callback parameter value is auto-generated which the RESTful service rejects. If I create a callback request parameter, then two callback values are passed. Is there a way to have a JSONP data type and a custom callback value? For this RESTful service, the callback must equal "YAHOO.Finance.SymbolSuggest.ssCallback".

Hello,

Yes you can invoke "YAHOO.Finance.SymbolSuggest.ssCallback" in service "success" event.

So add JS event handler on success event for your service and populate it with following code:

pre

YAHOO.Finance.SymbolSuggest.ssCallback(data);

/pre

Thanks for the screenshot, Yurii. I added the code but I'm not sure how to implement the actual callback function. Can you advise on the next steps on how to work with the data parameter?

If you don't need invoke "YAHOO.Finance.SymbolSuggest.ssCallback" event handler you can work with returned data directly in the "success" event handler.

For example:

pre

//This line of code will print to the debug console. Please check it out to see what is in your "data" returned object.
condole.log(data);

alert(data);

alert(data.length);

/pre

Also if it will not help please specify what exactly you want to do.

Thanks & regards.

Thank you for the quick reply. Below is how I call the service in jQuery, how can I incorporate this into Appery?
code
$.ajax({
type: "GET",
dataType: "jsonp",
jsonp: "callback",
jsonpCallback: "YAHOO.Finance.SymbolSuggest.ssCallback",
data: {
query: "msft"
},
url: "http://autoc.finance.yahoo.com/autoc"
});
/code
code
YAHOO.Finance.SymbolSuggest.ssCallback = function (data) {
alert(data.ResultSet.Result);
}
/code

Hello,

You can add this code to custom realization of Generic service: http://devcenter.appery.io/documentat...

We have tried the Generic service but we are having trouble getting it to work. Could you provide guidance based on the js provided above how we would setup a generic service?

Ideally, we would like to use a REST service configuration so could you be able to answer part of my question of Is there a way to have a JSONP data type and a custom callback value?

Hello,

Please follow the solution below:

1 Create generic service http://prntscr.com/434glf/direct.

2 Click "Add custom implementation"

3 Choose "new javascript" with name "genericService1JS". http://prntscr.com/434h6f/direct

4 Use following code in "JS" implementation:

pre

//Note replace "genericService1JS" with your value.
Appery.genericService1JS = Appery.createClass(null, {

 init : function(requestOptions) { 
     this.__requestOptions = $.extend({}, requestOptions); 
 }, 

 process : function(settings) { 

     if(!self.YAHOO || !YAHOO.Finance || !YAHOO.Finance.SymbolSuggest) 
         self.YAHOO = {Finance: {SymbolSuggest: {} } }; 

     $.ajax({ 
         type: "GET", 
         dataType: "jsonp", 
         jsonp: "callback", 
         jsonpCallback: "YAHOO.Finance.SymbolSuggest.ssCallback", 
         data: { 
             query: "msft" 
         }, 
         url: "http://autoc.finance.yahoo.com/autoc" 
     }); 

     YAHOO.Finance.SymbolSuggest.ssCallback = function (data) { 
         alert(data.ResultSet.Result); 

         settings.beforeSend(settings); 

         settings.success(data.ResultSet.Result); 

         settings.complete('success'); 
     } 

 } 

});

/pre
