如何解析的shell脚本网址参数 [英] How to parse URL params in shell script

问题描述

我已经试过同样的成功在python解析网址参数，但我想知道是否有一种方法做同样的shell脚本。

我说，我有一个URL值：

<一个href=\"http://www.abcdsample.com/listservices?a=1&b=10&c=abcdeeff&d=1663889&listservices=a|b\" rel=\"nofollow\">http://www.abcdsample.com/listservices?a=1&b=10&c=abcdeeff&d=1663889&listservices=a|b

所需的输出：

 网​​址：http://www.abcdsample.com/
服务：listservices
a = 1时
B = 10
C = abcdeeff
D = 1663889
listservices = A | B
 

解决方案

下面是一个方法：

  BEGIN {
    FS =？
}
{
    URL = $ 1
    子（/ [^ /] * $ /，URL）
    打印URL，网址    子（/.*[/]/,\"\",$ 1）
    打印服务，$ 1    N =拆分（$ 2，B，/＆安培; /）
    对于（i = 1; I＆LT; = N;我++）
        印片B [I]
}
 

另存为 script.awk 和运行像的awk -f script.awk文件：

 网​​址：http://www.abcdsample.com/
服务：listservices
a = 1时
B = 10
C = abcdeeff
D = 1663889
listservices = A | B
 

请注意：这会像URL工作：

• 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&listservices=a|b


• listservices一个= 1和b = 10和C = abcdeeff和D = 1663889＆放大器; listservices = A | B

I have tried the same successfully in python to parse URL params but I would like to know if there is a way to do the same in Shell Script.

Say, I have a URL value:

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

Required Output:

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

解决方案

Here is one method:

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]
}

Save it as script.awk and run like awk -f script.awk file:

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

Note: this will work for URL like:

• 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&listservices=a|b
• listservices?a=1&b=10&c=abcdeeff&d=1663889&listservices=a|b
