func CleanPath ¶

func CleanPath(p string) string

CleanPath is the URL version of path.Clean, it returns a canonical URL path for p, eliminating . and .. elements.

The following rules are applied iteratively until no further processing can be done:

1. Replace multiple slashes with a single slash.
2. Eliminate each . path name element (the current directory).
3. Eliminate each inner .. path name element (the parent directory) along with the non-.. element that precedes it.
4. Eliminate .. elements that begin a rooted path: that is, replace "/.." by "/" at the beginning of a path.

If the result of this process is an empty string, "/" is returned

func CompilePath ¶

func CompilePath(path string, caseSensitive bool, end bool) (*regexp.Regexp, []string)

1. Remove / ignore trailing / and /*

2. Adding a leading / to ensure canonical path had leading /

3. Remove all special meta character in the path (via regex QuoteMeta)

4. Escape all / into \\/

5. Extract all path param (ex: /path/:id => id is path param)

6. Also extract if wildcards exist in path (ex: /path/*)

func ExtractPathParam ¶
