url_encode and url_decode in Shell

Posted 2020-09-23 westfly

之前写过一版 shell下解码url，下面给出另外一个版本

from https://gist.github.com/cdown/1163649

function urlencode() {
    local LANG=C
    for ((i=0;i<${#1};i++)); do
        if [[ ${1:$i:1} =~ ^[a-zA-Z0-9\\.\\~\\_\\-]$ ]]; then
            printf "${1:$i:1}"
        else
            printf \'%%%02X\' "\'${1:$i:1}"
        fi
    done
}
urldecode() {
    # urldecode <string>

    local url_encoded="${1//+/ }"
    printf \'%b\' "${url_encoded//%/\\\\x}"
}

好用就行
