WebMap to json

Question

I use Web App Builder and I would like to know if there is a method to export the contents of a webmap to json. It is possible to open a webmap (json) like this :

https://developers.arcgis.com/javascript/jssamples/ags_createwebmapitem.html

but I have found nothing to export the webmap to json.

I tried the following method but it only records what is visible on the map.

var = Web_Map_as_JSON JSON.toJson (printTask._getPrintDefinition (this.map, params));

This method does not save everything in the toc and not visible on the map.

Unfortunately this is not a solution because I added services which was not in the original webmap.

Also, the basemap widget lets you change the basemap (different from the one in online)

Oh,that's true.  If your web map is already in ArcGIS Online or Portal for ArcGIS, you can export it in json format.  If you want to take a JavaScript map object and convert it to json (to be able to save it to AGOL or Portal), there is currently no way that I know of.

Sebastien,

You can try formatting the item id for your webmap in a request like this with f=pjson. If your map is shared with everyone this should work, otherwise, you'll need to embed a token in the request.

Hope this helps,
