I am using ESRI’s REST API to create a new Web Map with WMS layers. I am trying to run the POST request http://{{domain}}/portal/sharing/rest/content/users/{{username}}/addItem with the following in the body:
f: json
title: testMap
type: Web Map
token: {{token}}
text:
{
"operationalLayers": [
{
"id": "wms_3449",
"url": "http://mesonet.agron.iastate.edu/cgi-bin/wms/nexrad/n0r.cgi",
"visibility": true,
"visibleLayers": [
"nexrad-n0r"
],
"opacity": 1,
"title": "IEM WMS Service",
"layerType": "WMS",
"version": "1.3.0",
"mapUrl": "http://mesonet.agron.iastate.edu/cgi-bin/wms/nexrad/n0r.cgi",
"layers": [],
"spatialReferences": [
900913,
4326,
102100,
3857
],
"extent": [
[
-126,
24
],
[
-66,
50
]
],
"maxWidth": 2048,
"maxHeight": 2048
}
],
"baseMap": {
"baseMapLayers": [
{
"id": "defaultBasemap",
"layerType": "ArcGISTiledMapServiceLayer",
"url": "http://services.arcgisonline.com/ArcGIS/rest/services/ESRI_Imagery_World_2D/MapServer",
"visibility": true,
"opacity": 1,
"title": "ESRI_Imagery_World_2D"
}
],
"title": "ESRI_Imagery_World_2D"
},
"spatialReference": {
"latestWkid": 4326
}
}
Note, the WMS layer is based on the ArcGIS example using a WMS layer as an operational layer here: https://developers.arcgis.com/web-map-specification/objects/wmsLayer/ . When I try to create this map, it initially says
{
"success": true,
"id": "<whatever the id is>",
"folder": null
}
However, whenever I try to view the map using Map Viewer, I get an error message saying “The map cannot be drawn completely because one or more layers are not supported. These layers will be omitted.” From Map Viewer, when I go to Add->Add Layer from Web->A WMS OGC Web Service and put in the url from the text above, namely http://mesonet.agron.iastate.edu/cgi-bin/wms/nexrad/n0r.cgi?REQUEST=GetCapabilities&SERVICE=WMS, I get the following error: The WMS service, http://mesonet.agron.iastate.edu/cgi-bin/wms/nexrad/n0r.cgi, cannot be added to the map. It is either not available or you have entered an invalid URL for the type of layer you want to reference.
When I try to add this url manually, Fiddler says I got a 403 error when ArcGIS was trying to use a proxy for this request: GET /portal/sharing/proxy?https://mesonet.agron.iastate.edu/cgi-bin/wms/nexrad/n0r.cgi?SERVICE=WMS&REQUEST=GetCapabilities HTTP/1.1
Does anyone know what is causing these errors? I appreciate any feedback.
