How do I call my SOE using the JS API?

[chrisweaves]

Hi,

I have an SOE deployed and can call it fine using a browser using the following:

https://server/arcgis/rest/services/Testing/TestLayer/MapServer/exts/FeatureCountSOE/findNearbyFeatu...

That works fine and sends a json response with the feature count.

What I need is to replicate the call above but using the JS API, I have tried a few things but none seem to pass append the REST endpoint with the required parameters (layerId, location and distance), here's what I tried

var queryTask = new QueryTask({
    url:     "https://server/arcgis/rest/services/Testing/TestLayer/MapServer/exts/FeatureCountSOE/findNearbyFeatures",
    layerId: 0,
    distance: 10000,
    location: "{'x':0,'y':0,'spatialReference':{'wkid':3857}}",
    f: "json"
});

var query = new Query();
query.outFields = ["*"];
queryTask.execute(query).then(function(results){
    alert(results);
});

Am I way off the mark?  Feels like it 😕

Thanks for your help!

Chris,

   Yes a query task is not the right class to use. You need to use esriRequest.
