requestMatchesPathOrTemplate function

CharlatanRequestMatcher requestMatchesPathOrTemplate(String pathOrTemplate)

A function to build a CharlatanRequestMatcher that matches if the request path matches the provided pathOrTemplate.

Implementation

CharlatanRequestMatcher requestMatchesPathOrTemplate(String pathOrTemplate) =>
    (request) {
      final uri = Uri.parse(request.path);
      final template = UriTemplate(pathOrTemplate);
      final parser = UriParser(template);

      final match = parser.matches(uri);
      if (!match) {
        return false;
      }

      // by reversing the parse we're confirming that we match the right pattern
      // e.g. /goals/{id} will also be a match for /goals/{id}/foo
      // but we want to use a /goals/{id}/foo pattern if one exists
      final vars = parser.parse(uri);
      final reverseMatch = template.expand(vars) == uri.toString();
      if (!reverseMatch) {
        return false;
      }

      return true;
    };
