Azure SDK Python packages support for Python 2.7 has ended 01 January 2022. For more information and questions, please refer to https://github.com/Azure/azure-sdk-for-python/issues/20691

Getting started

Prerequisites

Python 3.7 or later is required to use this package.
An Azure subscription and an Azure Maps account.
A deployed Maps Services resource. You can create the resource via Azure Portal or Azure CLI.

If you use Azure CLI, replace <resource-group-name> and <account-name> of your choice, and select a proper pricing tier based on your needs via the <sku-name> parameter. Please refer to this page for more details.

az maps account create --resource-group <resource-group-name> --account-name <account-name> --sku <sku-name>

Install the package

Install the Azure Maps Service Geolocation SDK.

pip install azure-maps-geolocation

Create and Authenticate the MapsGeolocationClient

To create a client object to access the Azure Maps Geolocation API, you will need a credential object. Azure Maps Geolocation client also support two ways to authenticate.

1. Authenticate with a Subscription Key Credential

You can authenticate with your Azure Maps Subscription Key. Once the Azure Maps Subscription Key is created, set the value of the key as environment variable: AZURE_SUBSCRIPTION_KEY. Then pass an AZURE_SUBSCRIPTION_KEY as the credential parameter into an instance of AzureKeyCredential.

from azure.core.credentials import AzureKeyCredential
from azure.maps.geolocation import MapsGeolocationClient

credential = AzureKeyCredential(os.environ.get("AZURE_SUBSCRIPTION_KEY"))

geolocation_client = MapsGeolocationClient(
    credential=credential,
)

2. Authenticate with an Azure Active Directory credential

You can authenticate with Azure Active Directory (AAD) token credential using the Azure Identity library. Authentication by using AAD requires some initial setup:

Install azure-identity
Register a new AAD application
Grant access to Azure Maps by assigning the suitable role to your service principal. Please refer to the Manage authentication page.

After setup, you can choose which type of credential from azure.identity to use. As an example, DefaultAzureCredential can be used to authenticate the client:

Next, set the values of the client ID, tenant ID, and client secret of the AAD application as environment variables: AZURE_CLIENT_ID, AZURE_TENANT_ID, AZURE_CLIENT_SECRET

You will also need to specify the Azure Maps resource you intend to use by specifying the clientId in the client options. The Azure Maps resource client id can be found in the Authentication sections in the Azure Maps resource. Please refer to the documentation on how to find it.

from azure.maps.geolocation import MapsGeolocationClient
from azure.identity import DefaultAzureCredential

credential = DefaultAzureCredential()
geolocation_client = MapsGeolocationClient(
    client_id="<Azure Maps Client ID>",
    credential=credential
)

Key concepts

The Azure Maps Geolocation client library for Python allows you to interact with each of the components through the use of a dedicated client object.

Sync Clients

MapsGeolocationClient is the primary client for developers using the Azure Maps Geolocation client library for Python. Once you initialized a MapsGeolocationClient class, you can explore the methods on this client object to understand the different features of the Azure Maps Geolocation service that you can access.

Async Clients

This library includes a complete async API supported on Python 3.5+. To use it, you must first install an async transport, such as aiohttp. See azure-core documentation for more information.

Async clients and credentials should be closed when they're no longer needed. These objects are async context managers and define async close methods.

Examples

The following sections provide several code snippets covering some of the most common Azure Maps Geolocation tasks, including:

Get Geolocation

Get Geolocation

This service will return the ISO country code for the provided IP address. Developers can use this information to block or alter certain content based on geographical locations where the application is being viewed from.

from azure.maps.geolocation import MapsGeolocationClient

BLOCK_COUNTRY_LIST = ['US', 'TW', 'AF', 'AX', 'DL']
INCOME_IP_ADDRESS = "2001:4898:80e8:b::189"
geolocation_result = client.get_country_code(ip_address=INCOME_IP_ADDRESS)

result_country_code = geolocation_result.iso_code

if result_country_code in BLOCK_COUNTRY_LIST:
    raise Exception("These IP address is from forebiden country")

Troubleshooting

General

Maps Geolocation clients raise exceptions defined in Azure Core.

This list can be used for reference to catch thrown exceptions. To get the specific error code of the exception, use the error_code attribute, i.e, exception.error_code.

Logging

This library uses the standard logging library for logging. Basic information about HTTP sessions (URLs, headers, etc.) is logged at INFO level.

Detailed DEBUG level logging, including request/response bodies and unredacted headers, can be enabled on a client with the logging_enable argument:

import sys
import logging
from azure.maps.geolocation import MapsGeolocationClient

# Create a logger for the 'azure.maps.geolocation' SDK
logger = logging.getLogger('azure.maps.geolocation')
logger.setLevel(logging.DEBUG)

# Configure a console output
handler = logging.StreamHandler(stream=sys.stdout)
logger.addHandler(handler)

Next steps

More sample code

Get started with our Maps Geolocation samples (Async Version samples).

Several Azure Maps Geolocation Python SDK samples are available to you in the SDK's GitHub repository. These samples provide example code for additional scenarios commonly encountered while working with Maps Geolocation

set AZURE_SUBSCRIPTION_KEY="<RealSubscriptionKey>"

pip install azure-maps-geolocation --pre

python samples/sample_authentication.py
python sample/sample_get_country_code.py

Notes: --pre flag can be optionally added, it is to include pre-release and development versions for pip install. By default, pip only finds stable versions.

Further detail please refer to Samples Introduction
