'error': {'code': 498, 'message': 'Invalid Token'

Clive_S — Mon, 07 Dec 2020 11:34:55 GMT

I used the ESRI Python token code sample, which returns a token.

However when I use the token in <url+token>, I get an error??

formatted_json = [feature['attributes'] for feature in raw_json['features']] KeyError: 'features' {'error': {'code': 498, 'message': 'Invalid Token', 'details': []}}

The code is:

ef get_token(): params = {'username': username, 'password': password, 'expiration': str(60), 'client': 'referer', 'referer': referer, 'grant_type': 'client_credentials', 'client_id': client_id, 'client_secret': client_secret, 'f': 'json'} request = requests.get(token_url, params=params) response = request.json() #print(response) token = response['access_token'] return token portalToken = get_token() #### THIS works + returns Token #print(portalToken) ##print("END") if __name__ == "__get_token__": """optional location for parameters""" print(sys.argv[0])

The get_token returns a token.. they all seem to have .. at the end of the token?? This is really frustrating, would appreciate any pointers!!

Thanks,

Clive

I changed

the get to post, still getting invalid token error.

request = requests.get(token_url, params=params) to request = requests.post(token_url, params=params)

what does the query url look like with the token appended? do you have:

"&token=" + token

request.get(https://blablabla?f=json&token=hfwjfjkewkjfwkfjk..

Hi David,

Thanks for the reply.

I updated the code, got a more useful error.... I think??

def get_token(url, username, password): ''' use this to get a token from arcgis online ''' gen_token_url = token_url # payload params for the post request params = {'username':username, 'password':password,'client':'referer', 'referer':url, 'client_id': client_id, 'client_secret': client_secret, 'grant_type': grant_type, 'expiration':expiration, 'f':'json'} response = requests.post(gen_token_url, data=params, verify=False) data = response.json() # convert to json print('access_token') #return data['access_token'] mytoken = get_token(url, username, password) if __name__ == "__get_token__": """optional location for parameters""" print(sys.argv[0])

I added: client_id, 'client_secret': client_secret, 'grant_type': grant_type

Now I am getting a new error: InsecureRequestWarning: Unverified HTTPS request.

redirect_uri not specified

I don't want users to login!! I want to get a token to login

Yep, again, what is the request you're attempting?

Hi David.

I need to automate getting the Token.

The previous code returned a Token, but threw an invalid Token error consuming the REST end point (json = URL+Token).

I have a rest endpoint and URL.

If I go to 'https://mycomp.maps.arcgis.com/sharing/rest/oauth2/token', this provides a Token

Then if I use: json_file = url+token, this returns JSON.

Is this clearer??

DavidPike — Mon, 07 Dec 2020 12:42:59 GMT

what i mean is that since the issue seems to be the format of the post or get to your rest endpoint, it would be helpful to share what it looks like.

Hi David,

In the code:

#def get_token(url, username, password): def get_token(): ''' use this to get a token from arcgis online ''' gen_token_url = token_url # payload params for the post request params = {'username':username, 'password':password,'client':'referer', 'referer':url, 'client_id': client_id, 'client_secret': client_secret, 'grant_type': grant_type, 'expiration':expiration, 'f':'json'} response = requests.post(gen_token_url, data=params, verify=False) data = response.json() # convert to json return data['access_token'] mytoken = get_token() print(get_token) <<< warning

The warning is:

The error/warnig: C:\Users\user\anaconda3\python.exe C:/Users/user/PycharmProjects/pythonProject1/Test.py C:\Users\user\anaconda3\lib\site-packages\urllib3\connectionpool.py:979: InsecureRequestWarning: Unverified HTTPS request is being made to host 'eiffagekier.maps.arcgis.com'.

Hi David,

I thought that stated at the beginning of the post that if I create a Token using the Portal Form.

Then use that token in the REST url.

json_file = url+token, this returns the JSON. The issue that I have is trying to generate a Token.

This returns the error message/s.

DavidPike — Mon, 07 Dec 2020 14:24:22 GMT

OK.

Assuming username, password and url parameters are correct, your request seems to be missing headers - headers = {'content-type': 'application/x-www-form-urlencoded'}

are you passing the url as url = portalUrl + '/sharing/rest/generateToken?'

Also can't see the parameters of clientid secret and granttype.

import requests portalUrl = "https://domain/portal" username = 'username' password = "password" def generateToken(username, password, portalUrl): # Retrieves a token to be used with API requests. headers = {'content-type': 'application/x-www-form-urlencoded'} parameters = {'username': username, 'password': password, 'client': 'referer', 'referer': portalUrl, 'expiration': 60, 'f': 'json'} url = portalUrl + '/sharing/rest/generateToken?' response = requests.post(url, data=parameters, headers=headers) try: jsonResponse = response.json() if 'token' in jsonResponse: return jsonResponse['token'] elif 'error' in jsonResponse: print (jsonResponse['error']['message']) for detail in jsonResponse['error']['details']: print (detail) except ValueError: print('An unspecified error occurred.') print(ValueError) token = generateToken(username, password, portalUrl)

Hi David,

Thanks that header (

headers = {'content-type': 'application/x-www-form-urlencoded'}) Solved the problem.

Much appreciated

Hi David, I am getting a similar error in a standalone ArcGIS Server 10.5.1. I am trying to view a map services' item information (url = ServerURL/admin/services/ServiceName.MapServer/iteminfo/manifest/manifest.json).
I am able to generate the token but when I get the error as a response.
Any ideas on how to resolve or troubleshoot? This error does not occur in ArcGIS Enterprise 10.8.1

Hi, maybe best to create a new post to get more traction. I don't really understand why you're passing a token when you have the GIS object, or why you are using a mix of the Python API and REST API, is there a sample you're working from?
I can dig out a python API script to extract manifest details if you like? What do you need to achieve exactly?

Hi jxl090120,

Have you resolved this error? I am having the same problem! I also want to request content of manifest json. I would appreciate with any suggestions!

Hey David, at the time I didn't realize I could get to the manifest properties from the service object 😑 (i.e service.iteminformation.manifest). Doing so revolved my issue.

Re: 'error': {'code': 498, 'message': 'Invalid Token'

Joel_Lopez — Tue, 23 May 2023 19:06:39 GMT

Hi Lin, I ended up just getting to the manifest info through the service object.
services = gis_server.services.list()
for service in services:
man = service.iteminformation.manifest
print(man)
