Send Post request to an external API using AWS Lam

Question

I want to send a post request to an external API (https://example.com/api/jobs/test) every hour.

The Lambda Function that I used is as follows:

Handler: index.lambda_handler
python: 3.6

index.py

import requests
def lambda_handler(event, context):
  url="https://example.com/api/jobs/test"
  response = requests.post(url)
  print(response.text) #TEXT/HTML
  print(response.status_code, response.reason) #HTTP

Test Event:

 {
 "url": "https://example.com/api/jobs/test"
}

Error:

 START RequestId: 370eecb5-bfda-11e7-a2ed-373c1a03c17d Version: $LATEST
 Unable to import module 'index': No module named 'requests'

 END RequestId: 370eecb5-bfda-11e7-a2ed-373c1a03c17d
 REPORT RequestId: 370eecb5-bfda-11e7-a2ed-373c1a03c17d Duration: 0.65 ms   Billed Duration: 100 ms     Memory Size: 128 MB Max Memory Used: 21 MB  

Any help would be appreciated.

Answer 1

You need to install requests module to your project directory and create a lambda deployment package. See this link for details.

In short, you need to create your index.py file on you development system (PC or mac), install Python & pip on that system; them follow the steps in the doc. To create lambda, choose the 'Upload zip' option instead of the 'Edit inline' one

Answer 2

You may be able to leverage requests module from the boto library without having to install or package your function.

Consider this import: import botocore.vendored.requests as requests

Note: Vendored requests are being removed from botocore.
