Get `request` object from python (server) script in flask

I am trying to get the request object itself in Python; to strip out any attribute I need from it. For now, the headers, through flask, but I can't.

All the docs/questions/issues I find is about how to get the attributes from the response, but no word about how to get it from the request.

The context:

I am playing with Istio, and Istio appends some headers to the request, that I need to collect and forward to the next request in order for Istio to keep track of the metrics.

In Python, I can do it as follows:

...
    def do_GET(self):
        print(self.headers)
...

Which dumps the headers:

host: debian.istio-server.svc.cluster.local
user-agent: curl/7.59.0
accept: */*
x-forwarded-proto: http
x-request-id: 398756b5-87aa-93e3-8c02-ccd8e9027db3
x-envoy-decorator-operation: debian.istio-server.svc.cluster.local:80/*
x-istio-attributes: CkMKGGRlc3RpbmF0aW9uLnNlcnZpY2UuaG9zdBInEiVkZWJpYW4uaXN0aW8tc2VydmVyLnN2Yy5jbHVzdGVyLmxvY2FsCkEKF2Rlc3RpbmF0aW9uLnNlcnZpY2UudWlkEiYSJGlzdGlvOi8vaXN0aW8tc2VydmVyL3NlcnZpY2VzL2RlYmlhbgokChhkZXN0aW5hdGlvbi5zZXJ2aWNlLm5hbWUSCBIGZGViaWFuCi8KHWRlc3RpbmF0aW9uLnNlcnZpY2UubmFtZXNwYWNlEg4SDGlzdGlvLXNlcnZlcgpBCgpzb3VyY2UudWlkEjMSMWt1YmVybmV0ZXM6Ly9jdXJsZXItNzU1Y2M3Y2ZmZi1sYnJwNi5pc3Rpby1jbGllbnQ=

x-b3-spanid: fa406dd115edf516
x-b3-sampled: 1
content-length: 0

I am wondering if there is an equivalent in flask. Or any other way of getting the headers from the request, would be fine.

You should be able to import request from flask and read correctly the headers

Something like this:

from flask import request
...
    def do_GET():
        print(request.headers)
...
