Cannot use Requests-Module on AWS Lambda

EDIT: On Oct-21-2019 Botocore removed the vendored version of requests: https://github.com/boto/botocore/pull/1829.

EDIT 2: (March 10, 2020): The deprecation date for the Lambda service to bundle the requests module in the AWS SDK is now January 30, 2021. https://aws.amazon.com/blogs/compute/upcoming-changes-to-the-python-sdk-in-aws-lambda/

To use requests module, you can simply import requests from botocore.vendored. For example:

from botocore.vendored import requests

def lambda_handler(event, context):
   response = requests.get("https://httpbin.org/get", timeout=10)
   print(response.json())

you can see this gist to know more modules that can be imported directly in AWS lambda.

If you're working with Python on AWS Lambda, and need to use requests, you better use urllib3, it is currently supported on AWS Lambda and you can import it directly, check the example on urllib3 site.

import urllib3

http = urllib3.PoolManager()
r = http.request('GET', 'http://httpbin.org/robots.txt')

r.data
# b'User-agent: *\nDisallow: /deny\n'
r.status
# 200

I finally solved the problem: The structure in my zip file was broken. It is important that the python script and the packed dependencies (as folders) are in the root of the zip file. This solved my problem.

It's a bit depressing if you find such easy errors after hours of try and failure.
