kurl: Curl simplified

kurl.sh

#!/bin/bash

# Simplified curl
function kurl() {
    local delimiter=$'\x1E' # ASCII record separator
    local response=$(curl -s "$@" -w "${delimiter}%{http_code}")

    IFS="$delimiter" read -r body http_code <<< "$response"
    export HTTP_CODE="$http_code"
    echo $body

    local field_count=$(awk -F"$delimiter" '{print NF}' <<< "$body")
    if (( field_count != 2 )); then
        echo "Error: The response body contains the delimiter."
        return 1
    fi
}

Usage:

response_code=$(kurl -X GET https://httpstat.us/400)
if [ "$HTTP_CODE" -ne 200 ]; then
	echo "Error in response: $HTTP_CODE"
    exit 1
fi
echo "response body: $response_code"

My assumptions:

• While scripting, I care more about correctness and ease of writing than perf or anything else
• We rarely write concurrent code in bash so it's safe use global vars
