- A python library that allows you to register python web service to one or more
API GATEWAYcranker routers - it is the client endpoint of a
API GATEWAY
- 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)
-
There are mainly 4 steps:
pip install crank4py-connector- create a web service that hosts al requests on some path prefix, e.g.
/service-a/... - start a web service on a random port
- construct a
Configobject 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,
