urlencode

Cli tool to encode stdin to URL. This tool is a thin wrapper around the standard go escape functions PathEscape and QueryEscape from net/url.

Examples

$ ./urlencode.exe -h
urlencode (version: v0.7.0)

This program is a thin wrapper around the standard go url escape functions.
Available flags:

  -input string
    	string to escape, if empty (default) read from stdin
  -keep-spaces
    	keep spaces as they are
  -path-escape
    	use PathEscape instead of QueryEscape
  -trim
    	trim (from both sides) whitespaces and newlines

$ urlencode -input " Ceci est un message étrange "
+Ceci+est+un+message+%C3%A9trange+

$ echo " Ceci est un message étrange " | urlencode
+Ceci+est+un+message+%C3%A9trange+%0A

$ echo " Ceci est un message étrange " | urlencode -keep-spaces
 Ceci est un message %C3%A9trange %0A

$ echo " Ceci est un message étrange " | urlencode -path-escape
%20Ceci%20est%20un%20message%20%C3%A9trange%20%0A

$ echo " Ceci est un message étrange " | urlencode -trim
Ceci+est+un+message+%C3%A9trange

Note : echo adds a new line at the end that is visible as %0A if no trim option is used.

Some explanations

The url encoding is not the same before the ? and after it.

• Before the ? the spaces should be encodes as %20 (and not +). This part is encoded with PathEscape go function.
• After the ? the spaces could be encodes as + (%20 is also possible but is longer ). This part is encoded with QueryEscape go function.

If you want to encode some text in data: uri, for example in the case of data:image/xml+svg, ... you can use urlencode -path-escape -keep-spaces -trim.
