I'm trying to get a token for ArcGIS Online using C# (well, more specifically SSIS). I've got a URL I can use which works well, and I can hit it and get what I need in Chrome, but it won't work through C# using a WebClient.
I can get other JSONs through it through SSIS/C# WebClient, but NOT ArcGIS Online for some reason. The URL works through Chrome, but won't yield an answer through SSIS/C# WebClient.
My code (with client id/secret/credentials) is:
string webResource = "https://mymaps.maps.arcgis.com/sharing/rest/oauth2/token?client_id=MYCLIENTID&client_secret=MYCLIENTSECRET&grant_type=client_credentials"; WebClient wc = new WebClient(); string json = wc.DownloadString(webResource);
I would then parse the JSON.
Currently I'm getting:
DTS Script Task has encountered an exception in user code: project name: ST_0a306cf2e1634509bea49b75b7d93265 Exception has been thrown by the target of an invocation. at System.RuntimeMethodHandle.InvokeMethod(Object target, Object arguments, Signature sig, Boolean constructor) at System.Reflection.RuntimeMethodInfo.UnsafeInvokeInternal(Object obj, Object parameters, Object arguments) at System.Reflection.RuntimeMethodInfo.Invoke(Object obj, BindingFlags invokeAttr, Binder binder, Object parameters, CultureInfo culture) at System.RuntimeType.InvokeMember(String name, BindingFlags bindingFlags, Binder binder, Object target, Object providedArgs, ParameterModifier modifiers, CultureInfo culture, String namedParams) at Microsoft.SqlServer.Dts.Tasks.ScriptTask.VSTATaskScriptingEngine.ExecuteScript()
I have created an application, as described in https://developers.arcgis.com/labs/rest/get-an-access-token/
An example of the returned JSON (through Chrome) is:
