Error in sending Python API request from AWS Lambda python function-CodePudding

I am trying send a POST request from AWS python lambda function but getting following error while sending:

[ERROR] ConnectionError: HTTPConnectionPool(host='techmorecruitmenfrontend.s3-website.ap-south-1.amazonaws.com', port=80): Max retries exceeded with url: / (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7f69fdfbda90>: Failed to establish a new connection: [Errno 110] Connection timed out')) Traceback (most recent call last):

Response

I tried with the following code:

import json
import uuid
import datetime
import re
import base64
import requests
import httpx
import asyncio
def lambda_handler(event,context):

    INVENTORY_CP_OPERATION_URL="http://te************.s3-website.ap-south- 
                 1.amazonaws.com/"
    message={
       "email":"*******@****logics.com",
       "password":"123456"
        }
    result=requests.post(INVENTORY_CP_OPERATION_URL,json=message)
    return "success".

CodePudding user response：

Given your Connection timed out, it would seem that your AWS Lambda function is having difficulty connecting to the Internet.

When an AWS Lambda function is NOT connected to a VPC, it has direct access to the Internet.

However, when a Lambda function IS connected to a VPC, it only has Internet access if the Lambda function is connected to a private subnet and there is a NAT Gateway in a public subnet.

Therefore, if the function does not require access to any resources in a VPC (eg Amazon RDS databases), then it is best to disconnect it from the VPC.
