Integration with Flask¶
Note
Flask backend is optionaly supported. Library itself does not depend on Flask.
Create api instance¶
If you want to use default (global) object, skip this step. In most cases it is enough to start with it, even if you plan to add another version later. Default api is located here:
from jsonrpc.backend.flask import api
If you would like to use different api versions (not, you could name methods differently) or use custom dispatcher, use
from jsonrpc.backend.flask import JSONRPCAPI
api = JSONRPCAPI(dispatcher=<my_dispatcher>)
Later on we assume that you use default api instance.
Add api endpoint to the project¶
You have to options to add new endpoint to your Flask application.
First - register as a blueprint. In this case, as small bonus, you got a /map handler, which prints all registered methods.
from flask import Flask
from jsonrpc.backend.flask import api
app = Flask(__name__)
app.register_blueprint(api.as_blueprint())
Second - register as a usual view.
from flask import Flask
from jsonrpc.backend.flask import api
app = Flask(__name__)
app.add_url_rule('/', 'api', api.as_view(), methods=['POST'])
Add methods to api¶
@api.dispatcher.add_method
def my_method(*args, **kwargs):
return args, kwargs
Make requests to api¶
To use api, send POST request to api address. Make sure your message has correct format.
