Globus SDK Configuration

The behaviors of the SDK can be controlled either through environment variables, or by passing parameters to clients and other objects.

Note

SDK v1.x and v2.x supported the use of /etc/globus.cfg and ~/.globus.cfg to set certain values. This feature was removed in v3.0 in favor of new environment variables for setting these values.

Environment Variables

Each of these environment variables will be read automatically by the SDK.

Environment variables have lower precedence than explicit values set in the interpreter. If GLOBUS_SDK_VERIFY_SSL="false" is set and a client is created with verify_ssl=True, the resulting client will have SSL verification turned on.

GLOBUS_SDK_VERIFY_SSL

Used to disable SSL verification, typically to handle SSL-intercepting firewalls. By default, all connections to servers are verified. Set GLOBUS_SDK_VERIFY_SSL="false" to disable verification.

GLOBUS_SDK_HTTP_TIMEOUT

Adjust the timeout when HTTP requests are made. By default, requests have a 60 second read timeout – for slower responses, try setting GLOBUS_SDK_HTTP_TIMEOUT=120

GLOBUS_SDK_ENVIRONMENT

The name of the environment to use. Set GLOBUS_SDK_ENVIRONMENT="preview" to use the Globus Preview environment.

GLOBUS_SDK_SERVICE_URL_*

Override the URL used for a given service. The suffix of this environment variable must match the service name string used by the SDK in all caps (SEARCH, TRANSFER, etc). For example, set GLOBUS_SDK_SERVICE_URL_TRANSFER="https://proxy-device.example.org/" to direct the SDK to use a custom URL when contacting the Globus Transfer service.

Config-Related Functions

There are two functions available to translate the configuration described above into the URLs to use for accessing Globus services.

To return specifically the URL for the Globus Web App in a given environment:

globus_sdk.config.get_webapp_url(environment: str | None = None) → str

Return the URL to access the Globus web app in the given environment. For example:

>>> get_webapp_url("preview")
'https://app.preview.globus.org/'

Parameters:

environment (str, optional) – The name of the environment to use. If unspecified, this will use the GLOBUS_SDK_ENVIRONMENT environment variable.

To return the URL for any other service in a given environment:

globus_sdk.config.get_service_url(service: str, environment: str | None = None) → str

Return the base URL for the given service in this environment. For example:

>>> from globus_sdk.config import get_service_url
>>> get_service_url("auth", environment="preview")
'https://auth.preview.globus.org/'
>>> get_service_url("search", environment="production")
'https://search.api.globus.org/'

Parameters:

• service (str) – The short name of the service to get the URL for

• environment (str, optional) – The name of the environment to use. If unspecified, this will use the GLOBUS_SDK_ENVIRONMENT environment variable.

Note that no other imports from globus_sdk.config are considered public.
