querystring

Shell script helper functions for encoding/decoding querystring data.

Example

#!/usr/bin/env import
import "[email protected]"

querystring_escape "hello world"
# hello%20world

querystring_unescape "hello%20world"
# hello world

API

querystring $path

Outputs the querystring portion of the provided request URL. Once you have the querystring, it may be parsed with querystring_parse.

#!/usr/bin/env import
import "[email protected]"

querystring "/api/hello"
# (empty)

querystring "/api/hello?name=rick"
# name=rick

querystring_escape $input

Encodes the input with querystring percent-encoding. Similar to encodeURIComponent() in JavaScript.

#!/usr/bin/env import
import "[email protected]"

querystring_escape hello world
# hello%20world

# Also works over stdin
echo hello world | querystring_escape
# hello%20world

querystring_unescape $input

Decodes querystring-encoded content. Similar to decodeURIComponent() in JavaScript.

#!/usr/bin/env import
import "[email protected]"

querystring_unescape "hello%20world"
# hello world

querystring_parse $qs $var1 <... $var2>

Parses the provided qs querystring and sets the requested shell variables.

#!/usr/bin/env import
import "[email protected]"

querystring_parse "one=1&two=2&three=3" one two

echo "$one"
# 1

echo "$two"
# 2

echo "$three"
# Not set, since it was not requested in `querystring_parse`
