Catalyst AppSail

Catalyst AppSail is a fully-managed, independent, Platform-as-a-service (PaaS) component of Catalyst Serverless that enables you to develop and deploy services in the cloud with ease. Unlike Catalyst Serverless functions that you code following a Catalyst-specific template based on the function type, AppSail services can be developed independently of any coding structures.

Execute Python SDK in AppSail

You can import the Python SDK in your code for your Catalyst app. The SDK will need to be initialized with the request object before each request.

The configuration can be set using the following code snippet:

Below is an example of how to import and initialize the Python SDK in a Flask web app.

    

        
copy
        

            

        
    
    

         from flask import Flask, request, g
import os
import zcatalyst_sdk
from zcatalyst_sdk.catalyst_app import CatalystApp
app = Flask(__name__)
@app.before_request
def before_request():
    if request.path.startswith('/admin'):
        return 'Unauthorized', 401
    # if authorized user
    g.zc_app = zcatalyst_sdk.initialize(req=request)
@app.route('/')
def index():
    return 'Web App with Python Flask!'
@app.route('/cache')
def cache():
    app: CatalystApp = g.zc_app
    resp = app.cache().segment().put('key', 'value')
    return resp, 200
listen_port = os.getenv('X_ZOHO_CATALYST_LISTEN_PORT', 9000)
app.run(host='0.0.0.0', port = listen_port)
