Hey my friend, I need your help. I try to download a file in url like ([http://google.com/favicon.ico](http://google.com/favicon.ico)). It works well locally with (“requests” , “urllib3” , “urllib.request” ), but it doesn’t work with nameko. I can’t solve this problem. My code likes this:

```
from nameko.web.handlers import http
import requests

class MyService:
    name = "my_service"

    @http("POST", "/post/my")
    def do_post(self, request):
        url = "http://google.com/favicon.ico"
        r = requests.get(url, allow_redirects=True)
        print(r.status)
        open("google.ico", "wb").write(r.content)
        return u"received: {}".format(request.get_data(as_text=True))

```

and the error is always like this.  
“wrap\_socket() got an unexpected keyword argument ‘\_context’”

Can anyone help me pls.

In fact, I have already tried “requests” , “urllib3” , “urllib.request” . these three libs of python 3.7.4. But They all have the same error.

And it works well in python3.7.4 without nameko.

Could you paste entire stack trace of the error here? How are you running the service?

The python file is like above named “test-nameko.py”.

I run it in shell with command : nameko run test-nameko

And I do the simple http request with insomnia(with postman has the same error)

Hi @yuut007 unfortunately looks like eventlet library which is a nameko’s dependency is the root cause of the issue here as documented here: [https://github.com/eventlet/eventlet/issues/526](https://github.com/eventlet/eventlet/issues/526)

We have a test reproducing this issue and tracking it with: [https://github.com/nameko/nameko/pull/644](https://github.com/nameko/nameko/pull/644)

Is it possible for you to use Python 3.6 in meantime?

Thanks a million. 😁 It works with python3.6. I am willing to tracking this problem with 3.7 in the future.
