firebase use flask route get "ECONNRESET" ,The restful api never response until 60s timeout

[xactester]

@app.post("/api/test")
def stuff():
    abc = flask.request.get_data()
    # abc= flask.request.get_json();
    print("Jsondata:", abc)
    # name = flask.request.args.get('name')
    # print("name:", name)
    data = {'Message': 'Hello World'}
    return jsonify(data), 200

@https_fn.on_request()
def httpsflaskexample(req: https_fn.Request) -> https_fn.Response:
    with app.request_context(req.environ):
        return app.full_dispatch_request()

A sample like firebase_documents
If i remove request.get_data(), It will be ok.

I'm having the same problem when i call flask.request.get_data() in post
this is the traceback:
Traceback (most recent call last):

File "D:\MyDemo\functions\venv\lib\site-packages\flask\app.py", line 1508, in finalize_request
response = self.process_response(response)
File "D:\MyDemo\functions\venv\lib\site-packages\flask\app.py", line 2002, in process_response
response = self.ensure_sync(func)(response)
File "D:\MyDemo\functions\venv\lib\site-packages\functions_framework_init_.py", line 302, in read_request
flask.request.get_data()
File "D:\MyDemo\functions\venv\lib\site-packages\werkzeug\wrappers\request.py", line 420, in get_data
rv = self.stream.read()

data = self.read(1024 * 64)
File "D:\MyDemo\functions\venv\lib\site-packages\werkzeug\wsgi.py", line 562, in readinto
self.on_disconnect()

stuck in read and then timeout. if post with no body, it's fine.

By the way , i use the firebase emulators

I found a temporary solution.

@https_fn.on_request()
def httpsflaskexample(req: https_fn.Request) -> https_fn.Response:
    with app.request_context(req.environ):
        g.request = req
        return app.full_dispatch_request()

then use g.request in post function

@app.post("/api/test")
def stuff():
    abc = g.request.get_data()
    # abc= flask.request.get_json();
    print("Jsondata:", abc)
    # name = flask.request.args.get('name')
    # print("name:", name)
    data = {'Message': 'Hello World'}
    return jsonify(data), 200

Hello @fzrcyc. I am doing a POST request to the URL both through the emulator and on a live deployment using the following command:

# Example for request to local emulator
curl -X POST http://127.0.0.1:5001/ff-test-74aeb/asia-south1/httpsflaskexample/api/test -d '{"key": "value"}' -H "Content-Type: application/json"

I get the following response back:

{"Message":"Hello World"}

This is the code I have in my main.py file:

from firebase_functions import https_fn, options
import flask
from flask import jsonify

app = flask.Flask(__name__)


@app.post("/api/test")
def stuff():
    abc = flask.request.get_data()
    # abc= flask.request.get_json();
    print("Jsondata:", abc)
    # name = flask.request.args.get('name')
    # print("name:", name)
    data = {'Message': 'Hello World'}
    return jsonify(data), 200


options.set_global_options(
    max_instances=10, region=options.SupportedRegion.ASIA_SOUTH1)


@https_fn.on_request()
def httpsflaskexample(req: https_fn.Request) -> https_fn.Response:
    with app.request_context(req.environ):
        return app.full_dispatch_request()

Could you please provide a reproducible example for this issue as I cannot reproduce it using the code sample you provided?

Same issue with request.json which calls get_json
@fzrcyc work around worked but very hacky lol
