SWS API Client

This library provides the user with a set of useful tools to easily interact with the FAO SWS (Statistical Working System) REST APIs.

Installation

The module is available on Pypi:

python -m pip install sws_api_client

The library requires Python 3.9+.

Usage

To use the package the user needs to create an instance of the SwsApiClient class, provide it with the necessary parameters and execute the methods to query the specific endpoints.

Instantiate the client locally

There are three methods to instantiate the client:

1. Pass the sws_endpoint and the access_token to the constructor

from sws_api_client import SwsApiClient

sws_client = SwsApiClient(sws_endpoint="<sws_endpoint>", access_token="<access_token>")

2. Pass to sws_endpoint and the access_token as named arguments

We need to execute the script from command line passing --sws_endpoint and --access_token as arguments:

python script.py --sws_endpoint <endpoint> --access_token <test_access_token>

And instantiate the client in our script with the class method from_args:

from sws_api_client import SwsApiClient

sws_client = SwsApiClient.from_args()

3. Create a conf file where to store the arguments

We need to create a conf file (default name: "conf_sws_api_client.json") with the following structure:

{
    "sws_endpoint": "https://sws.dev.fao.org",
    "sws_token": "XXX",
    "current_task_id": "XXX",
    "current_execution_id": "XXX",
    "authclient": {
        "clientId": "XXX",
        "clientSecret": "XXX",
        "tokenEndpoint": "https://fao-dev.auth.eu-west-1.amazoncognito.com/oauth2/token",
        "scope": "sws/user"
    }
}

And instantiate the client in our script with the class method auto:

from sws_api_client import SwsApiClient

sws_client = SwsApiClient.auto()

Behind the scene it will automatically detect the fact that you are in debug mode and it will instanciate the client using the from_conf method

Instantiate the client in a SWS plugin

When working withing a SWS plugin instantiate the client as:

from sws_api_client import SwsApiClient

sws_client = SwsApiClient.auto()

Behind the scene it will automatically detect the fact that you are in a SWS plugin and it will instanciate the client using the from_env method

Instantiate the client using env variables

You can also instantiate the client using the following environment variables:

export SWS_ENDPOINT=https://sws.fao.org
export SWS_TOKEN=XXX
export SWS_USER_CREDENTIALS_SECRET_NAME=dev/sws/user_client

If you have no access to the SWS_USER_CREDENTIALS_SECRET_NAME you can use the following environment variables:

export SWS_AUTH_CLIENTID=XXX
export SWS_AUTH_CLIENTSECRET=XXX
export SWS_AUTH_TOKENENDPOINT=XXX
export SWS_AUTH_SCOPE=XXX

And instantiate the client in our script with the class method from_env:

from sws_api_client import SwsApiClient

sws_client = SwsApiClient.from_env()

Access different API Services

The library provides a set of classes to interact with the different services available in the SWS API. The available classes are:

• Tags to interact with the SWS Tags API
• Datasets to interact with the Datasets API provided by both the legacy SWS IS Api and the new Session API
• Tasks to interact with the SWS TaskManager API
• Datatable to interact with the SWS Datatable API
• Plugins to interact with the SWS Plugins API

Perform requests

To perform requests you just need to call the available methods using the SwsApiClient object, as an example:

datasets = Datasets(sws_client)
dataset = datasets.get_dataset_info('aproduction')
logger.info(f"Dataset info: {dataset}")

or to get the list of tags:

tags = Tags(sws_client)
tags_list = tags.get_tags()
logger.info(f"Tags: {tags_list}")

more complete examples can be found in the example folder:

cp example/conf_sws_api_client.json.example example/conf_sws_api_client.json
# edit the file with your credentials
python3 -m venv example/.venv
source example/.venv/bin/activate
pip install -r example/requirements
python example/dataset_example.py

If you need to perform a test request not in debug mode, you can use the following command:

AWS_PROFILE=fao-dev DEBUG_MODE=FALSE SWS_USER_CREDENTIALS_SECRET_NAME=dev/sws/user_client SWS_TOKEN=YOUR_TOKEN SWS_ENDPOINT=https://sws.dev.fao.org python3 dataset_example.py
