Create token and access feature Layer

kapalczynski

I have this code snip below.

Trying to get a token
return that token
and use gis.content.get(feature_layer_id) to secure access to a service

Line 14 The variable "custom_token" prints with no issues
Line 18 prints fine as well "Token successfully generated! Expires at timestamp: 1780364453189"
Line 21 prints back NONE
and Line 23 gives error: Exception: You do not have permissions to access this resource or perform this operation.
(Error Code: 403)

The user Name and password are owner level permissions and have access to everything in our Enterprise... so im confused.

AND confused why line 21 returns NONE

The reson I am going this route is I need to increase the token expiration time... not sure how to do it any other way...

otherwise I would just do this

if portal_username == '' and portal_password == '':
    gis = GIS(profile='Survey123_prof')
else:
    gis = GIS(portal_url, portal_username, portal_password)
    
token = gis._con.token
item_object = gis.content.get(feature_layer_id)

ANY thoughts?

token_url = f"{portal_url}/sharing/rest/generateToken"
payload = {
    "username": portal_username,
    "password": portal_password,
    "client": "referer",
    "referer": portal_url,
    "expiration": expiration_minutes,
    "f": "json"
}

response = requests.post(token_url, data=payload)
token_data = response.json()
custom_token = token_data["token"]
print("custom token " + custom_token)

gis = GIS(url=portal_url, credentials={"token": custom_token})

print(f"Token successfully generated! Expires at timestamp: {token_data['expires']}")

tokenvalue = gis._con.token
print(tokenvalue)

item_object = gis.content.get(feature_layer_id)
print(item_object)

If I run it with this:

gis = GIS(url=portal_url, token=custom_token)

Instead of this

gis = GIS(url=portal_url, credentials={"token": custom_token})

I get this error

....snip

I have run into token issues like this with portal in the past. Below is the basic method that has worked for me. .

gis = GIS("https://xyz:7443/arcgis", "xxUNxx", "xxPWxx", verify_cert=False)
token = gis.session.auth.token
auth_info = (gis.session.auth)

After this, I place the token in a dictionary {"token": token}, then store it in a csv for other scripts to access or just use it in my active python requests. Good luck. I know this issue can be frustrating.

@BrianLomas doesn't the token expire on you though

I am not sure what this is and how that would play into my script.... how would that work with the simple example below
Or the more elaborate one in this post...

if portal_username == '' and portal_password == '':
    gis = GIS(profile='Survey123_prof')
else:
    gis = GIS(portal_url, portal_username, portal_password)
    
token = gis._con.token
item_object = gis.content.get(feature_layer_id)

Or the more elaborate one below...

token_url = f"{portal_url}/sharing/rest/generateToken"
payload = {
    "username": portal_username,
    "password": portal_password,
    "client": "referer",
    "referer": portal_url,
    "expiration": expiration_minutes,
    "f": "json"
}

response = requests.post(token_url, data=payload)
token_data = response.json()
custom_token = token_data["token"]

print("custom token " + custom_token)

#gis = GIS(url=portal_url, token=custom_token)
gis = GIS(url=portal_url, credentials={"token": custom_token})

print(f"Token successfully generated! Expires at timestamp: {token_data['expires']}")

print("Portal: ", portal_url)
print("Referer: ", payload.get("referer"))
print("GIS Referrer: ", getattr(gis, '_referer', 'Not set'))

tokenvalue = gis._con.token
print(tokenvalue)

token = custom_token
print(tokenvalue)

item_object = gis.content.get(feature_layer_id)
print(item_object)
