Injecting a Flask Request into another Flask App

Question

Is there a way to inject a Flask request object into a different Flask app. This is what I\'m trying to do:

app = flask.Flask(__name__)

@app.route(\'/foo/&l         


        

Answer 1

I wouldn't recommend this method, but this is technically possible by abusing the request stack and rewriting the current request and re-dispatching it.

However, you'll still need to do some type of custom "routing" to properly set the url_rule, as the incoming request from GCF won't have it (unless you explicitly provide it via the request):

from flask import Flask, _request_ctx_stack
from werkzeug.routing import Rule

app = Flask(__name__)

@app.route('/hi')
def hi(*args, **kwargs):
    return 'Hi!'

def say_hello(request):
    ctx = _request_ctx_stack.top
    request = ctx.request
    request.url_rule = Rule('/hi', endpoint='hi')
    ctx.request = request
    _request_ctx_stack.push(ctx)
    return app.dispatch_request()
