In-depth knowledge of the principles of URL encoding (Percent-encoding)
URL Encoding (URL) Encoding, officially coded as a percentage number (Percent-encoding), is a common resource identifier (URI) . The code mechanism for special characters. Because only a small part of the URL is allowed to be used Characters, any character beyond this range (e.g. Chinese, special symbols or spaces) must be converted to be correctly identified by the browser and server.
Why do you need URL encoding?
URLs have specific syntax structures. For example, `? ' for marking the start of the parameters for query, ` ` ` for separating multiple parameters, `= ` to link the key pair. If you include these symbols in the parameter values themselves (e.g., a search word is: "R&B" () The browser is misleading. Encoding through URL, "&" will be converted to '%26 ', thus ensuring URL The logical structure of the project is intact.
URL Encoding Relationship to UTF-8
In modern Web applications, URL encoding is usually based on the UTF-8 character set. For Non-ASCII Character (in Chinese, for example) is converted to a byte series of UTF-8s, and each byte is marked as `% ' Then it's the form of two hexadecimals. For example, the Chinese character "You" is coded UTF-8 as `E4 BD A0 ' at URL , as `%E4%BD%A0 ' .
Common URL Encoding Application scene
- API interface call: When you pass parameters containing special characters through the GET request.
- The website jumps and redirects: Target URL contains dynamically generated parameters.
- Processing spaces: The spaces in URLs are usually coded as `%20 ' or `+ ' (in the query string).
- Prevent XSS attacks: In some cases, the encodement of URLs entered by users is part of the safety protection.
How efficiently to parse URL parameters?
Manually extract parameters from a long string of URLs. This tool has built in a smart resolution engine that automatically recognizes '? ' , and break it down to a clear key value to the table. Whatever layers of code the parameter has been encoded, our solvers can return it to readable original text, greatly increasing the developer ' s debugging efficiency.
