Invalid Endpoint when try to run boto3 client with custom SQS hostname with _

[webjoaoneto]

Describe the bug

To reproduce:

import boto3

queue_url = "http://reports_locals:9324/000000000000/account-configs-dev"
queue_region = "us-east-2"

sqs_client = boto3.client("sqs", endpoint_url=queue_url, region_name=queue_region)

When url has "_" characters boto check raises:

    raise ValueError(f"Invalid endpoint: {endpoint_url}")

Regression Issue

• Select this option if this issue appears to be a regression.

Expected Behavior

do not raise any execption

Current Behavior

raises an execption with invalid url

Reproduction Steps

import boto3

queue_url = "http://reports-locals:9324/000000000000/account-configs-dev"
queue_region = "us-east-2"

sqs_client = boto3.client("sqs", endpoint_url=queue_url, region_name=queue_region)

Possible Solution

rewrite the url validation regex to allow these patterns with _

Workaround to avoid problems:

import socket

#
# replace the URL to the ip address
# these solution might not working depending of your environment
#
def replace_domain_name_to_ip(full_url):
    domain_name_part = full_url.split("//")[1].split(":")[0]
    domain_name_ip = socket.gethostbyname(domain_name_part)
    return full_url.replace(domain_name_part, domain_name_ip)
