Cannot use Requests-Module on AWS Lambda

Question

I need to do a rest-call within a python script, that runs once per day. I can't pack the "requests" package into my python-package using the AWS Lambdas. I get the error: "Unable to import module 'lambda_function': No module named lambda_function"

I broke it down to the hello_world predefined script. I can pack it into a zip and upload it. Everything works. As soon as I put "import requests" into the file, I get this error.

Here is what I already did:

1. The permissions of the zip and the project folder (including subfolders) are set to `chmod 777`. So permissions shouldn't be a problem.
2. The script itself is within the root folder. When you open the zip file, you directly see it.
3. I installed the requests package into the root-folder of the project using `sudo pip install requests -t PATH_TO_ROOT_FOLDER`

The naming of everything looks like this:

• zip-file: lambda_function.zip
• py-file: lambda_function.py
• handler method: lambda_handler(event, context)
• handler-definition in the "webconfig: lambda_function.lambda_handler

The file I want to run in the end looks like this:

import requests import json   def lambda_handler(event, context):     url = 'xxx.elasticbeanstalk.com/users/login'     headers = {"content-type": "application/json", "Authorization": "Basic Zxxxxxxxxx3NjxxZxxxxzcw==" }     response = requests.put(url, headers=headers, verify=False)     return 'hello lambda_handler' 

I'm glad for ANY kind of help. I already used multiple hours on this issue.

Answer 1

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.
