Generating Token By URL Request From ArcGIS Portal?

MehdiPira1 — Sun, 12 Dec 2021 10:17:55 GMT

Hi,

I'm trying to generate a token from a Portal url. It generates a token when pasting this link into a web browser:

https://portalUrl/sharing/rest/generateToken?&f=json

but when I run this code:

function getToken(portalUrl, username, password) {
  var xmlhttp = new XMLHttpRequest();
  var url = "https://portalUrl/sharing/rest/generateToken?username=username&password=password&f=json";


  xmlhttp.open("POST", url, false);
  xmlhttp.send();

  if (xmlhttp.status == 200) {
    var responseJSON = JSON.parse(xmlhttp.responseText)
    if (responseJSON && !responseJSON.error) {
      return responseJSON.token;      
    } else {
      return "ERROR";
    }   
  } else {
    return "ERROR"
  }
}‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

I get an error.

and I've created this in XHR code too:

var xhr = new XMLHttpRequest();
xhr.withCredentials = true;

xhr.addEventListener("readystatechange", function() {
  if(this.readyState === 4) {
    console.log(this.responseText);
  }
});

xhr.open("POST", "https://portalUrl/sharing/rest/generateToken?username=username&password=password&f=json");

xhr.send();‍‍‍‍‍‍‍‍‍‍‍‍

and this throws the following error:

{"error":{"code":400,"message":"Unable to generate token.","details":["POST request should not contain username and password in the query string."]}}

Any ideas or help is appreciated.

Thank you.

Hi Mehdi,

If you have Windows Authentication enabled on the web adaptor, you will need to go around the web adaptor and specify the server name where portal is installed (i.e. server.domain.com:7443/arcgis). Ex:

import requests, json

# Disable warnings
requests.packages.urllib3.disable_warnings()

username = "gis\jskinner"
password = "********"

tokenURL = 'https://server.domain.com:7443/arcgis/sharing/rest/generateToken/'
params = {'f': 'pjson', 'username': username, 'password': password, 'referer': 'https://server.domain.com'}

r = requests.post(tokenURL, data = params, verify=False)
response = json.loads(r.content)
token = response['token']
print(token)‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

If Windows Authentication is not enabled, you specify the web adaptor URL (i.e. server.domain.com/portal):

import requests, json

# Disable warnings
requests.packages.urllib3.disable_warnings()

username = "gis\jskinner"
password = "********"

tokenURL = 'https://server.domain.com/portal/sharing/rest/generateToken/'
params = {'f': 'pjson', 'username': username, 'password': password, 'referer': 'https://server.domain.com'}

r = requests.post(tokenURL, data = params, verify=False)
response = json.loads(r.content)
token = response['token']
print(token)‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

I also ran into this. I included the username and password in the body of the request instead of the header and that solved the issue!
