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
URL Encoding Examples
| Original Character | URL Encoded Result | Description |
|---|---|---|
| Space | %20 or + | Most common encoded character in URLs |
| 中 | %E4%B8%AD | Chinese character encoding |
| ? | %3F | Character with special meaning in URLs |
| = | %3D | Query parameter separator |
| @ | %40 | Used in email addresses |
