I have tried using the python rich plugin with TYK on docker.
The api works but the middleware doesn’t.
TYK outputs the following message:
level=error msg=“Driver ‘python’ isn’t loaded” prefix=coprocess
tyk.conf:

}
middleware.py:
from tyk.decorators import *
from gateway import TykGateway as tyk
from time import time
@Hook
def PreHook(request, session, spec):
tyk.log(“PreHook is called”, “info”)
# Inject a header:
request.add_header(“testheader”, “testvalue”)
return request, session
@Hook
def ResponseHook(request, response, session, metadata, spec):
tyk.log(“ResponseHook is called”, “info”)
# In this hook we have access to the response object, to inspect it, uncomment the following line:
# print(response)
tyk.log(“ResponseHook: upstream returned {0}”.format(response.status_code), “info”)
return response
Also when I use the ResponseHook
with the following definition:
“response”: [
{
“name”: “ResponseHook”,
“path”: “./bundles/middleware.py”
}
],
The middleware still don’t work and no error output message is written.
Is something wrong with this configuration?
Or maybe my docker image is missing something?
Thanks in advence.
