Basic Knowledge of URL Encoding and Decoding

What is URL Encoding?

URL Encoding is a method of converting non-ASCII characters and special characters in URLs into a format that can be safely transmitted. Encoded characters are represented by a percent sign (%) followed by two hexadecimal digits.

Why is URL Encoding Needed?

  • Ensure URLs are safely transmitted across various network protocols
  • Solve issues with special characters that have specific meanings in URLs
  • Support the use of non-ASCII characters (such as Chinese) in URLs
  • Prevent URL parsing errors and security vulnerabilities

Common Encoding Rules

• Letters and numbers remain unchanged

• Certain punctuation marks (hyphens, underscores, dots, tildes) remain unchanged

• Spaces are encoded as %20 or + sign

• Other characters are converted to %XX format according to UTF-8 encoding rules

Common Application Scenarios

  • Include special characters in URL query parameters
  • Build links containing Chinese or other non-ASCII characters
  • Process form submission data
  • Encode parameters when making API calls
  • Handle special characters during URL redirection
