使用perl和html的链接中的空格

Question

I have a problem with spaces using perl. I'm taking my informations from a db and I'm using them for a query string, but if there is a space, I can't validate my page.

<a href="fish.cgi?fish=White Shark">White Shark</a>

Is there something I can do?

Answer 1

Turn your URLs into URI objects which will take care of all escaping and normalization for you. They can also be used as strings.

use URI;

# Prints fish.cgi?fish=White%20Shark
print URI->new("fish.cgi?fish=White Shark");

I'd recommend this over individually escaping URIs. Once you have a URI object, you know it's safe to use.

Answer 2

You can replace the spaces in links with %20 which is the URL-encoded version for a space. You may have to strip this out again after it's been posted, not quite sure.

Example: www.google.ca/this site would be encoded as www.google.ca/this%20site

So your version would be fish.cgi?fish=White%20Shark , this should post properly.
