如何在shell腳本中解析URL參數

Question

我已經嘗試過在python中成功解析URL參數，但我想知道是否有方法在Shell腳本中執行同樣的操作。

說，我有一個URL值：

http://www.abcdsample.com/listservices?a=1&b=10&c=abcdeeff&d=1663889&listservices=a|b

所需的輸出：

URL: http://www.abcdsample.com/ 
Service: listservices 
a=1 
b=10 
c=abcdeeff 
d=1663889 
listservices=a|b 

Answer 1

這裏有一個方法：

BEGIN{ 
    FS="?" 
} 
{ 
    url=$1 
    sub(/[^/]*$/,"",url) 
    print "URL:",url 

    sub(/.*[/]/,"",$1) 
    print "Service:",$1 

    n=split($2,b,/&/) 
    for (i=1;i<=n;i++) 
     print b[i] 
} 

保存爲script.awk和運行像awk -f script.awk file：

URL: http://www.abcdsample.com/ 
Service: listservices 
a=1 
b=10 
c=abcdeeff 
d=1663889 
listservices=a|b 

注：這會爲URL工作像：

• http://www.abcdsample.com/listservices?a=1&b=10&c=abcdeeff&d=1663889&listservices=a|b
• www.abcdsample.com/listservices?a=1 & B = 10 & C = abcdeeff & d = 1663889 & listservices = a | b
• abcdsample.com/listservices?a=1 & b = 10 & c = abcdeeff & d = 1663889 &個listservices = A | B
• listservices一個= 1 & B = 10 & C = abcdeeff & d = 1663889個& listservices = A | B與GNU AWK

Answer 2

一種方式：

$ gawk -F'&' '{ 
    $0 = gensub(/(^[^/]+[/][/][^/]+[/])([^?]+)[?]/,"\\1\\&\\2\\&","") 
    print "URL:",$1 
    print "Service:",$2 
    for (i=3;i<=NF;i++) 
     print $i 
}' file 
URL: http://www.abcdsample.com/ 
Service: listservices 
a=1 
b=10 
c=abcdeeff 
d=1663889 
listservices=a|b
