class arcgis.auth.api.EsriSession(auth=None, cert=None, verify_cert=True, allow_redirects=True, headers=None, referer='http', **kwargs)

Bases: object

The EsriSession class is designed to simplify access to the Esri WebGIS environments without the additional components of the arcgis or arcpy modules. It is designed to allow users to connect and manage all HTTP calls themselves with no hand holding.

Security is handled through the requests authentication model. Leveraging authentication handlers and primarily connecting to 10.8.1+ enterprise components.

The supported Authentication Schemes are:

Username/Password

Oauth 2

IWA/NTLM

Basic

Digest

PKI

API Keys

User Provided Tokens

Kerberos

Anyone can extend the authentication handlers by creating a class and inheriting from requests.auth.AuthBase.

The EsriSession authentication supports authentication chaining. Meaning users can stack authentication methods.

auth1 + auth2 + auth3

It is recommended that you do not stack unneeded authenicators because they can caused unintended failures.

Parameter	Description
auth	Optional AuthBase. This is a security handler that performs some sort of security check.
cert	Optional Tuple. The client side certificate as a tuple or string. It should be noted that EsriSession does not support encrypted private keys.
verify_cert	Optional Bool. When False all SSL certificate errors are ignored. The default is True.
allow_redirects	Optional Bool. When False if the URL redirects a user, an error will be raised. The default is True
headers	Optional Dict. An additional set of key/value(s) to append to any request’s header.
referer	Optional Str. The referer header value. The default is http. This is mainly used with token security.

Optional Arguments

Parameter	Description
trust_env	Optional Bool. The default is True. If False proxies will cause an error to be raised if set by .netrc files.
stream	Optional Bool. To enable handling streaming responses, set stream to True and iterate over the response with iter_lines. The default is False.
check_hostname	Optional Bool. When connecting to a side via IP Address with an SSL certificate, the hostname will not match. This allows a user to specify the hostname in the headers parameters and ignore hostname errors.
retries	Optional Int. The max number of tries to retry a service for 50x errors.
backoff_factor	Optional float. The amount of time in seconds to wait between retries.
status_to_retry	Optional Tuple. The status codes to run retries on. The default is (413, 429, 503, 500, 502, 504).
method_whitelist	Optional List. When retries is specified, the user can specifiy what methods are retried. The default is ‘POST’, ‘DELETE’, ‘GET’, ‘HEAD’, ‘OPTIONS’, ‘PUT’, ‘TRACE’
proxies	Optional Dict. A key/value mapping where the keys are the transfer protocol and the value is the <url>:<port>. example `python proxies = {"http" : 127.0.0.1:8080, "https" : 127.0.0.1:8081} session = EsriSession(proxies=proxies) `
