Hello,

I created a gp service that allows to load a csv file (It contains addresses and It is attached at this post).

It works as expected :

I get an Item ID.

I created a gp service that allows to geocode addresses (from the Item ID generated at the step previous) :

In a Web Application, I use the Geoprocessor class to execute the task :

It works. The json output file is created on the server in \arcgisjobs\batchgeocode3_gpserver\<ID>\scratch:

Bertrand_Laurancin_7-1625755603160.png

 

However, I'm not able to get the result in the client-side (web app).

I think I must use waitForJobCompletion() method but I tried unsuccessfully.

Could you help me please ?

Thank you,

Bertrand

Following code works for me.

 

// upload file
var fileUploadUrl = gpserviceUrl + '/uploads/upload'
esri.request({
url: fileUploadUrl,
form: dojo.byId(uploadForm),
content: { f: "json" },
handleAs : "text",
},{usePost: true, useProxy:false}).then(uploadSucceeded, uploadFailed);

 

function uploadSucceeded(response){
var jsonObj = JSON.parse(response);

var status = jsonObj["success"];
if(status == true){
var item = jsonObj["item"];
var itemID = item["itemID"]
//console.log("itemID", itemID);

// gp process

var params = {'CSV_File': "{'itemID':'" + itemID + "'}", 'X_Field': xfield_value, 'Y_Field': yfield_value, 'Polygon_Data': polygon_data, 'statistics_type': statisticstype_value, 'statistics_field': statisticsfield_value};
console.log(params);

gp.submitJob(params, completeCallback, statusCallback);

} else {
$('#loadingDiv').css( "display", "none");
window.alert("Error: upload failed...");
}
}
function uploadFailed(response){
$('#loadingDiv').css( "display", "none");
alert('Upload failed: ', response);
}
