return status of GP call

jaykapalczynski — Sat, 11 Dec 2021 09:54:55 GMT

I cant seem to get the results of my GP call....is Synchronous call so .execute would be used.

What am I missing here?

I think I have to use the getResultData because of the Synchronous service

additionally I have an output parameter on the service...I would like to learn how to caputure this value as well

Noting that this works fine:

gpJSON.execute(params);

var HistoricUser = document.getElementById(JSONstring).value;

var params = {
      request: HistoricUser               
};

gpJSON.execute(params).then(function (jobInfo) {
                    
    var jobid = jobInfo.jobId;

    var requestOptions = {
         interval: 500,
         statusCallback: function (j) {
            console.log("Job Status: ", j.jobStatus);
         }
    };

    gpJSON.getResultData(jobId, resultName, requestOptions).then(function () {
         alert("job completed");
    });            
});‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

It's difficult to say without seeing the code run, but how are you defining resultName? I think you need a string value there of the name of the result parameter. What does gpJSON look like if you add a breakpoint before the getResultData and inspect it in the console? A simple codepen or something would help troubleshoot as well.

This works:

gpJSON.execute(params);

This does not:

gpJSON.execute(params).then(function (jobInfo) {

// snip

var gpUrlJSON ="https://xxxx.gov/arcgis/rest/services/DGIF_Test/createJSON/GPServer/createJSON";
var gpJSON = new Geoprocessor(gpUrlJSON);‍‍‍‍

my return parameter is called "result"...I changed my code to this but still nothing

I dont even get into the function to return a simple alert as seen below....so something is going wrong

gpJSON.getResultData(jobId, result, requestOptions).then(function () {
alert("jobId");
});

In my code above it I alert the Jobid I get UNDEFINED

var jobid = jobInfo.jobId;
alert(jobid);

Re: return status of GP call

Noah-Sager — Fri, 03 Apr 2020 19:46:22 GMT

Ok, so this never works?

gpJSON.execute(params).then(function (jobInfo) {

What does gpJSON.execute(params) return?

Can you host a simplified app on codepen or somewhere that shows this? That would make it a lot easier to troubleshoot.

Re: return status of GP call

jaykapalczynski — Fri, 03 Apr 2020 20:09:49 GMT

it still passes the parameter and the python script works...but it does not return anything....as I mentioned if I try and alert the jobid i get "undefined"

its in a huge app right now...trying to think of way to shrink ot down....will try and post something a bit later...

Hi jay kapalczynski‌,

Please check your published gptask whether it is sync or async.

If sync, we shall find out more like that

gpJSON.execute(params, lang.hitch(this, function (jobInfo) {
//job submit success case
}),
function(err){
//this is in error case
console.log("I got error with job execution")
console.log(err);
}
);‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

If async, use submitJob.

gpJSON.submitJob(params, lang.hitch(this, function (jobInfo) {

   //do what you need
     gpJSON.getResultData(jobInfo.jobId, "Results", lang.hitch(this, function (result) {

//result....
});

}));

‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

lang is for dojo/_base/lang , better to import and use that way not to lose your this context.

First off when the below is run it properly sends the parameter to the GP Service and the python script behind the scenes functions properly...

BUT I am not getting anything back or anything written to the console. I do not even get the alert to fire in the .execute function.

No errors in the console....Im puzzled.

I am definitely Synchronous

I have a .net c# webpage that I am clicking a button as you can see below. Using a window.JSControlller to get to my JS Function.....

BUT I am now getting an error relating to the LANG which I think I have referenced correctly in the JS File...

.ASPX PAGE

<asp:Button ID="btnGISPush" runat="server" OnClientClick="window.JsController.btnGISPush_Click()" Text="GIS Push"  CausesValidation="true" /><br />
 ‍‍‍‍‍‍‍‍

ENTIRE JS PAGE

I added the requires for dojo lang....but nothing happening and no alerts from withing the function and not err going to console...hmmmmm

require(["dojo/_base/lang"], function(lang){  // lang now contains the module features});

require([
    "esri/tasks/Geoprocessor", "dojo/_base/lang"
], function (Geoprocessor, lang) {
        "use strict";

        var gpUrlJSON ="https://xxxx.gov/arcgis/rest/services/Test/createJSON/GPServer/createJSON";
        var gpJSON = new Geoprocessor(gpUrlJSON);

        window.JsController = {
            btnGISPush_Click: function () {
                // Capture String value to populate params
                var HistoricUser = document.getElementById(JSONstring).value;
                alert("Parameter being passed: " + HistoricUser);

                var params = {
                    request: HistoricUser
                };

                gpJSON.execute(params, lang.hitch(this, function (jobInfo) {
                    //job submit success case
                    var jobid = jobInfo.jobId;

                    alert("jobId stringify: " + JSON.stringify(jobid));
                    console.log("jobId: " + jobid);
                }),
                    function (err) {
                        //this is in error case
                        console.log("I got error with job execution")
                        console.log(err);
                    }
                );

            }   // END OF BUTTON CLICK FUNCTION

        };   // END OF JS CONTROLLER

}); // END OF REQUIRE‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Now trying this with no success.....not one alert comes up BUT the parameter is passed properly and the python script runs successfully...no return of any kind and no error....uggggg

Hi jay kapalczynski‌,

Getting there

Check your network traffic, may be try with chrome debugger, network tab.

Does your gptask/job return any response?

Re: return status of GP call

jaykapalczynski — Sun, 05 Apr 2020 13:46:26 GMT

Im really puzzled...if I execute and pass the parameter as such above it works and my python script creates a polygon from the passed parameter....BUT I dont get anything back....well I get the below back but cant grab it

If I run right from the service I get this... the big comma delimited "Value" returned below are the IDs of the multi part polygon that is created that I pass back in an output parameter called "result"

I want to return the status AND the below returned parameters and write them to a variable...

Dont know why I cant get them back....I mean the code above in my last post does not even fire a general alert?

Re: return status of GP call

jaykapalczynski — Sun, 05 Apr 2020 16:50:40 GMT

ok so I striped down all the code to a simple .net solution. Might make what I am trying to do more clear..

Important files: demo.aspx and the JS folder index.js

1. I have a textbox with and example of the string that I am passing to the GP Service

2. I have a button that when clicked calls the JS code and passes a string variable to the GP tool , the same as in the textbox above

3. I am then simply trying to alert the status of the request and eventually the "value" that the GP Service is returning

....so write status to textbox or something updating every second or so....or just an alert would do

....result of the "Value" returned from the GP Service to a textbox or something....even an alert

I cannot even get an alert to fire inside the gpJSON.execute

Please see attached .zip file with the striped down .net app

jaykapalczynski — Sun, 05 Apr 2020 20:06:13 GMT

Please see my last couple post....as for debugger....not really sure what I am looking for...

I do see this ???

Hi jay kapalczynski‌,

Well I just have a look your code.

The problem is the asp.net button postback make your form to fully reload and the gptask code is working well.

I add sample with normal html client button vs asp.net button.

And need to adjust the param call as well.

asp.net button click does not make quite noticeable on postback to reload but you can catch by date time log.

Once gptask is executed, form is reload so all the context lost and task will not execute.

Whereas client side button work smoothly.

Please take a look at the sample.

For asp.net web form, I shall suggest to use ajax manager to prevent postback, and disable postback form validation and so on.

You need to check a lot of factor.

Re: return status of GP call

jaykapalczynski — Mon, 06 Apr 2020 13:24:20 GMT

THANK YOU very much Than....I really think the main issue was the button itself and it being within the Form....I totally missed the postback and form reload from the button click
