What does urlencode mean?

Editor to share with you what urlencode means, I believe that most people do not know much about it, so share this article for your reference, I hope you will learn a lot after reading this article, let's go to understand it!

Urlencode

Urlencode is a function that encodes a string in URL for encoding processing. URL coding (URL encoding), also known as percent coding (Percent-encoding), is the encoding mechanism of context-specific uniform resource locator (URL). The encoding that applies to the uniform Resource Identifier (URI) is also used to prepare data for the "application/x-www-form-urlencoded" MIME because it is used to submit HTML form data through the HTTP's request operation (request).

Coding principle

Convert the characters that need to be transcoded into hexadecimal, then from right to left, take 4 bits (less than 4 bits directly processed), do one bit for every 2 bits, add% before it, and encode it into% XY format.

For example, if the space ASCII code is 32 and the corresponding hexadecimal is 20, then the urlencode coding result is:% 20, but in the new standard, the space corresponds to +. See RFC-1738 for example: medium ASCII code is-10544, corresponding hexadecimal is D6D0, then urlencode coding result is:% D6%D0

Example
