• 5 min read
Proper URL encoding is crucial for web development. Learn best practices, common pitfalls, and how to use URL encoding tools effectively in your projects.
Developer Use Cases
API Query Parameters
Encode search terms and filters properly when calling REST APIs.
GET /api/search?q=user%20input&filter=active
Form Data Submission
application/x-www-form-urlencoded requires proper encoding of form values.
name=John%20Doe&email=john%40example.com
OAuth & Redirects
Encode callback URLs and state parameters in OAuth flows.
redirect_uri=https%3A%2F%2Fexample.com%2Fcallback
Best Practices
- ✓Encode user input - Always encode data from users before adding to URLs
- ✓Use built-in functions - encodeURIComponent() in JavaScript, urllib.parse.quote() in Python
- ✓Don't double-encode - Check if data is already encoded
- ✓Handle special characters - Remember that +, &, = have special meanings in query strings
