Moesif Middleware for Python WSGI based flatforms (Flask, Bottle & Others)

Project description

Moesif Middleware for Python WSGI based Frameworks

Built For Latest Version Language Versions Software License Source Code

WSGI middleware that logs incoming or outgoing API calls and sends to Moesif for API analytics and log analysis. Supports Python Frameworks built on WSGI such as Flask, Bottle, and Pyramid.

Source Code on GitHub

WSGI (Web Server Gateway Interface) is a standard (PEP 3333) that describes how a web server communicates with web applications. Many Python Frameworks are build on top of WSGI, such as Flask, Bottle, Pyramid etc. Moesif WSGI Middleware help APIs that are build on top of these Frameworks to easily integrate with Moesif.

How to install

pip install moesifwsgi

How to use

Flask

Wrap your wsgi_app with the Moesif middleware.

from moesifwsgi import MoesifMiddleware

moesif_settings = {
    'APPLICATION_ID': 'Your Moesif Application id',
    'LOG_BODY': True,
    # ... For other options see below.
}

app.wsgi_app = MoesifMiddleware(app.wsgi_app, moesif_settings)

Your Moesif Application Id can be found in the Moesif Portal. After signing up for a Moesif account, your Moesif Application Id will be displayed during the onboarding steps.

You can always find your Moesif Application Id at any time by logging into the Moesif Portal, click on the top right menu, and then clicking Installation.

For an example with Flask, see example in the /examples/flask folder of this repo.

Bottle

Wrap your bottle app with the Moesif middleware.

from moesifwsgi import MoesifMiddleware

app = bottle.Bottle()

moesif_settings = {
    'APPLICATION_ID': 'Your Moesif Application Id',
    'LOG_BODY': True,
    # ... For other options see below.
}

bottle.run(app=MoesifMiddleware(app, moesif_settings))

For an example with Bottle, see example in the /examples/bottle folder of this repo.

Pyramid

from pyramid.config import Configurator
from moesifwsgi import MoesifMiddleware

if __name__ == '__main__':
    config = Configurator()
    config.add_route('hello', '/')
    config.scan()
    app = config.make_wsgi_app()

    # configure your moesif settings
    moesif_settings = {
        'APPLICATION_ID': 'Your Moesif Application Id',
        'LOG_BODY': True,
        # ... For other options see below.
    }
    # Put middleware
    app = MoesifMiddleware(app, moesif_settings)

    server = make_server('0.0.0.0', 8080, app)
    server.serve_forever()

Other WSGI frameworks

If you are using a framework that is built on top of WSGI, it should work just by adding the Moesif middleware. Please read the documentation for your specific framework on how to add middleware.

Configuration options

APPLICATION_ID

(required), string, is obtained via your Moesif Account, this is required.

SKIP

(optional) (app, environ) => boolean, a function that takes a WSGI app and an environ, and returns true if you want to skip this particular event. The app is the original WSGI app instance, and the environ is a WSGI environ.

IDENTIFY_USER

(optional, but highly recommended) (app, environ) => string, a function that takes an app and an environ, and returns a string that is the user id used by your system. While Moesif tries to identify users automatically, but different frameworks and your implementation might be very different, it would be helpful and much more accurate to provide this function.

IDENTIFY_COMPANY

(optional) (app, environ) => string, a function that takes an app and an environ, and returns a string that is the company id for this event.

GET_METADATA

(optional) (app, environ) => dictionary, a function that takes an app and an environ, and returns a dictionary (must be able to be encoded into JSON). This allows your to associate this event with custom metadata. For example, you may want to save a VM instance_id, a trace_id, or a tenant_id with the request.

GET_SESSION_TOKEN

(optional) (app, environ) => string, a function that takes an app and an environ, and returns a string that is the session token for this event. Again, Moesif tries to get the session token automatically, but if you setup is very different from standard, this function will be very help for tying events together, and help you replay the events.

MASK_EVENT_MODEL

(optional) (EventModel) => EventModel, a function that takes an EventModel and returns an EventModel with desired data removed. The return value must be a valid EventModel required by Moesif data ingestion API. For details regarding EventModel please see the Moesif Python API Documentation.

DEBUG

(optional) boolean, a flag to see debugging messages.

LOG_BODY

(optional) boolean, default True, Set to False to remove logging request and response body.

CAPTURE_OUTGOING_REQUESTS

boolean, Default False. Set to True to capture all outgoing API calls from your app to third parties like Stripe or to your own dependencies while using Requests library. The options below is applied to outgoing API calls. When the request is outgoing, for options functions that take request and response as input arguments, the request and response objects passed in are Requests request or response objects.

SKIP_OUTGOING

(optional) (req, res) => boolean, a function that takes a Requests request and response, and returns true if you want to skip this particular event.

IDENTIFY_USER_OUTGOING

(optional, but highly recommended) (req, res) => string, a function that takes Requests request and response, and returns a string that is the user id used by your system. While Moesif tries to identify users automatically, but different frameworks and your implementation might be very different, it would be helpful and much more accurate to provide this function.

IDENTIFY_COMPANY_OUTGOING

(optional) (req, res) => string, a function that takes Requests request and response, and returns a string that is the company id for this event.

GET_METADATA_OUTGOING

(optional) (req, res) => dictionary, a function that takes Requests request and response, and returns a dictionary (must be able to be encoded into JSON). This allows to associate this event with custom metadata. For example, you may want to save a VM instance_id, a trace_id, or a tenant_id with the request.

GET_SESSION_TOKEN_OUTGOING

(optional) (req, res) => string, a function that takes Requests request and response, and returns a string that is the session token for this event. Again, Moesif tries to get the session token automatically, but if you setup is very different from standard, this function will be very help for tying events together, and help you replay the events.

LOG_BODY_OUTGOING

(optional) boolean, default True, Set to False to remove logging request and response body.

Example:

def identify_user(app, environ):
    # Your custom code that returns a user id string
    return "12345"

def identify_company(app, environ):
    # Your custom code that returns a company id string
    return "67890"

def should_skip(app, environ):
    # Your custom code that returns true to skip logging
    return "health/probe" in environ.get('PATH_INFO', '')

def get_token(app, environ):
    # If you don't want to use the standard WSGI session token,
    # add your custom code that returns a string for session/API token
    return "XXXXXXXXXXXXXX"

def mask_event(eventmodel):
    # Your custom code to change or remove any sensitive fields
    if 'password' in eventmodel.response.body:
        eventmodel.response.body['password'] = None
    return eventmodel

def get_metadata(app, environ):
    return {
        'datacenter': 'westus',
        'deployment_version': 'v1.2.3',
    }
