What it is

URL Parser is best for protocol/host/path checks, while Query Parser is best for parameter values and repeated keys.

When to use it

  • - Inspecting host, path, and hash parts of a URL.
  • - Reviewing query values and repeated parameter keys.
  • - Troubleshooting broken redirect links step by step.

Common misunderstandings

  • - One tool alone is not always enough.
  • - Query Parser does not validate full URL anatomy.
  • - URL Parser is not a full replacement for value decoding checks.

How to try it now

  1. Start with URL Parser to verify overall structure.
  2. Pass the query part to Query Parser for value checks.
  3. Use URL encode/decode for suspicious individual values.
  4. Re-check the final URL in both tools.

Example

Input

https://example.com/search?q=cuvel%20tools&tag=web&tag=nuxt#top

Output

URL Parser: host=example.com, path=/search
Query Parser: {"q":"cuvel tools","tag":["web","nuxt"]}

Notes

  • - Separating structure checks from value checks speeds up debugging.
  • - Repeated keys are often intentional arrays.
  • - Encoding issues are a common root cause of odd values.

FAQ

Which one should I start with?

Start with URL Parser for structure issues, Query Parser for value issues.

Can Query Parser accept a full URL?

Yes, but pairing it with URL Parser is safer for structure validation.

How should I isolate a broken URL?

Check structure first, then query contents, then individual value encoding.
