get request failing in boto3 python 3.8 lambda

I am trying to write a lambda function in 3.8 version but I am getting error while doing a get requests 

[ERROR] AttributeError: module 'botocore.vendored.requests' has no attribute 'get' Traceback (most recent call last):   File "/var/task/lambda_function.py"

import json
from botocore.vendored import requests

def lambda_handler(event, context):

    request = event['Records'][0]['cf']['request']
    print (request)
    print(request['headers'])
    token = request['headers']['cookie'][0]['value'].partition("=")[2]
    print (token)
    print(type(request['uri']))
    consumer_id = request['uri'].rpartition('/')[-1]
    print (consumer_id)

    #Take the token and send it somewhere
    token_response = requests.get(url = 'https://url/api/files/'  + consumer_id, params = {'token': token})
    print (token_response)

    return request

I tried following this blog https://aws.amazon.com/blogs/compute/upcoming-changes-to-the-python-sdk-in-aws-lambda/

but not able to identify which layer to add. Could anyone please help

I found a solution on Python runtime 3.9, so this isn't guaranteed to work for any other versions. I do not claim that this is the best solution, but it worked for me and may point others towards a better solution as the currently available answers do not solve the problem.

  1. Create a local directory for your Lambda function code and dependencies.

  2. Create your Lambda function code in a file in your new local directory you made in step #1. Name it lambda_function.py:

    import requests
from datetime import datetime

def lambda_handler(event, context):
    # Your code goes here
    print(datetime.now())
    response = requests.get('https://api.example.com')
    return response.text

  3. Install the requests library in your project directory. This is important for Python runtime in AWS Lambda:

    pip install requests -t ./

  4. Compress your local directory into a ZIP file.

  5. Upload your ZIP file to the AWS Lambda function. Ensure your project contents are in the root of the default folder.

You want to create a layer with a requests installed onto zip file before hand and then use import requests

According to the link you provided and assuming that request was correctly installed you should be using 

import requests

instead of

from botocore.vendored import requests
