這是純粹的BASH答案。rawurlencode()?{

local?string="${1}"

local?strlen=${#string}

local?encoded=""

local?pos?c?o??for?((?pos=0?;?pos

c=${string:$pos:1}

case?"$c"?in

[-_.~a-zA-Z0-9]?)?o="${c}"?;;

*?)???????????????printf?-v?o?'%%%02x'?"'$c"

esac

encoded+="${o}"

done

echo?"${encoded}"????#?You?can?either?set?a?return?variable?(FASTER)

REPLY="${encoded}"???#+or?echo?the?result?(EASIER)...?or?both...?:p}

您可以通過兩種方式使用它：easier:??echo?http://url/q?=$(?rawurlencode?"$args"?)faster:??rawurlencode?"$args";?echo?http://url/q?${REPLY}

這是匹配的rawurldecode()函數，它具有所有的謙虛性，非常棒。#?Returns?a?string?in?which?the?sequences?with?percent?(%)?signs?followed?by#?two?hex?digits?have?been?replaced?with?literal?characters.rawurldecode()?{

#?This?is?perhaps?a?risky?gambit,?but?since?all?escape?characters?must?be

#?encoded,?we?can?replace?%NN?with?\xNN?and?pass?the?lot?to?printf?-b,?which

#?will?decode?hex?for?us

printf?-v?REPLY?'%b'?"${1//%/\\x}"?#?You?can?either?set?a?return?variable?(FASTER)

echo?"${REPLY}"??#+or?echo?the?result?(EASIER)...?or?both...?:p}

通過匹配集，我們現在可以執行一些簡單的測試：$?diff?rawurlencode.inc.sh?\????????

如果你真的覺得你需要一個外部工具(好吧，它會更快，可能會做二進制文件等......)我在OpenWRT路由器上發現了這個......replace_value=$(echo?$replace_value?|?sed?-f?/usr/lib/ddns/url_escape.sed)

url_escape.sed是包含以下規則的文件：#?sed?url?escapings:%:%25:g

s:?:%20:g

s:<:>

s:>:%3E:g

s:#:%23:g

s:{:%7B:g

s:}:%7D:g

s:|:%7C:g

s:\\:%5C:g

s:\^:%5E:g

s:~:%7E:g

s:\[:%5B:g

s:\]:%5D:g

s:`:%60:g

s:;:%3B:g

s:/:%2F:g

s:?:%3F:g

s^:^%3A^g

s:@:%40:g

s:=:%3D:g

s:&:%26:g

s:\$:%24:g

s:\!:%21:g

s:\*:%2A:g
