URL encoding replaces unsafe ASCII characters with a "%" followed by two hexadecimal digits. URLs cannot contain spaces. URL encoding normally replaces a space with a plus (+) sign or with %20.
Why do we need to encode? URLs can only have certain characters from the standard 128 character ASCII set. Reserved characters that do not belong to this set must be encoded. This means that we need to encode these characters when passing into a URL.
URLEncoder is the way to go. You only need to keep in mind to encode only the individual query string parameter name and/or value, not the entire URL, for sure not the query string parameter separator character & nor the parameter name-value separator character = .
URL escape codes for characters that must be escaped lists the characters that must be escaped in URLs. If you must escape a character in a string literal, you must use the dollar sign ($) instead of percent (%); for example, use query=title%20EQ%20"$3CMy title$3E" instead of query=title%20EQ%20'%3CMy title%3E' .
I'm using httpc:request to post some data to a remote service. I have the post working but the data in the body() of the post comes through as is, without any URL-encoding which causes the post to fail when parsed by the remote service.
Is there a function in Erlang that is similar to CGI.escape in Ruby for this purpose?
