Automation to update a vector tile service referenced with feature service

CharliePatrier — Wed, 27 Sep 2023 05:12:42 GMT

Hi,

We are using ArcGIS Entreprise 11.1 with a federated server and we would like to automate the caching of our vector tile layers.

Our vector tile service has an associated, referenced feature service which allows the rebuild cache Rest operation:

Clicking on the "Rebuild Cache" button is working perfectly, therefore it looks like a great way to automate using this method.

We are aiming to automate the rebuild cache daily by reproducing this rest operation and we tried running the following script:

import urllib import json '''Retrieves a token to be used with API requests.''' data = urllib.parse.urlencode({'username' : 'username', 'password' : 'password', 'client' : 'https://XXX/server/rest/services', 'referer': 'https://YYY/portal/sharing/rest', 'expiration': 60, 'f' : 'json'}).encode('utf-8') response = urllib.request.urlopen('https://YYY/portal' + '/sharing/rest/generateToken',data).read().decode('utf-8') rebuildcacheurl = 'https://XXX/server/rest/services/System/CachingControllers/GPServer/Manage%20Vector%20Tile%20Cache/submitJob?serviceName=GX_WGS84_BaseMap&serviceFolder=Hosted&tilingFormat=INDEXED&f=json&token=' token = json.loads(response)['token'] submitjob = urllib.request.urlopen(rebuildcacheurl+token).read().decode('utf-8')

We have been unsuccessful so far and we are receiving this error response:

I have been trying to find documentation but I couldn't get anything which solve our issue.

Any help would be appreciated.

Thanks a lot!

Hi @CharliePatrier,

Have you tried using Postman to create the request for you? This image may help you get this in the right format 🙂

Postman can convert cURL requests to python - you then simply need to create a two-stage script.

getToken() (return Token)

rebuildCache(Token)

Thanks @A_Wyn_Jones it worked this way, very good outcome!

We took inspiration from your workflow and made a custom FME transformer using HTTPCallers.

Hi @CharliePatrier and @StaffanstorpsKommun

To revisit this one, You can also call for the recreation of a cache via the ArcGIS Server admin endpoint - this should've been my first suggestion!

Only for ArcGIS Online Though @A_Wyn_Jones? That particular endpoint does not exist in Enterprise, and you have to use the System/CachingControllers/GPServer/Manage%20Vector%20Tile%20Cache method?

To help everybody, this is the Python script we came up with:

import urllib import json import requests ### data to be sent for token generation on Portal token_data = urllib.parse.urlencode({'username' : 'XXX', 'password' : 'YYY', 'referer': 'URL ArcGIS Server with webadaptor', 'expiration': 60, 'f' : ''}).encode('utf-8') ### getting token from ArcGIS server token_response = urllib.request.urlopen('URL ArcGIS Server with webadaptor' + '/tokens/generateToken', token_data).read().decode('utf-8') ### vector tile url to request in order to submit cache job rebuildcacheurl = 'URL ArcGIS Server with webadaptor/rest/services/System/CachingControllers/GPServer/Manage%20Vector%20Tile%20Cache/submitJob?serviceName=ServiceName&serviceFolder=Hosted&tilingFormat=INDEXED&f=json&token=' ## header required for cache job request rebuildcache_headers = { 'authority': 'Full Computer name of ArcGIs Server location', 'accept': '*/*', 'origin': 'URL ArcGIS Portal', 'referer': 'URL ArcGIS Portal/'} ### submitting cache job response = requests.request("GET", rebuildcacheurl+token_response, headers=rebuildcache_headers) print('Job has been submitted') print('URL ArcGIS Server with webadaptor/rest/services/System/CachingControllers/GPServer/Manage%20Vector%20Tile%20Cache/jobs/'+response.json()['jobId']+'?f=html')

@StaffanstorpsKommun Yes! My apologies, only for ArcGIS Online!

Got excited reading the WRONG documentation 😄 Mondays!
