title: Go url parameters mapping
body: <p>Is there a native way for inplace url parameters in native <code>Go</code>?</p>
  
  <p>For Example, if I have a URL: <code>http://localhost:8080/blob/123/test</code> I want to use this URL as <code>/blob/{id}/test</code>.</p>
  
  <p>This is not a question about finding <code>go</code> libraries. I am starting with the basic question, does go itself provide a basic facility to do this natively.</p>
