crank4py-connector's Introduction

crank4y-connector

A python library that allows you to register python web service to one or more API GATEWAY cranker routers
it is the client endpoint of a API GATEWAY

Dependencies:

python >= 3.6
numpy(optional, for better performance)
requests
yarl
websocket-client == 0.57.0 (pls use this version, do not try higher version, trust me, there are bugs in higher versions)

Usage

There are mainly 4 steps:
1. pip install crank4py-connector
2. create a web service that hosts al requests on some path prefix, e.g. /service-a/...
3. start a web service on a random port
4. construct a Config object and start a connector
example

from flask import Flask
from crank4py_connector import Config
from crank4py_connector import create_and_start_connector

router_uris = ["wss://localhost:9070", "wss://localhost:9070"]
my_service_uri = "http://localhost:5000"  
config = Config(my_service_uri, "service-a", router_uris, component_name="service-a-component")
connector = create_and_start_connector(config)

app = Flask(__name__, static_url_path="")
@app.route("/service-a/hello")
def hello():
    return "hello"
app.run(host="localhost", port=5000)

# or you can refer to crank4py_connector
# and then you can query your api gateway to access your server-a. e.g. if your router listens on https://localhost:9000, then you can access  https://localhost:9000/service-a/hello,
