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

To add a parameter to the URL, add a /#/? to the end, followed by the parameter name, an equal sign (=), and the value of the parameter. You can add multiple parameters by including an ampersand (&) between each one.
Query parameters are a defined set of parameters attached to the end of a url. They are extensions of the URL that are used to help define specific content or actions based on the data being passed. To append query params to the end of a URL, a '? ' Is added followed immediately by a query parameter.
Path parameters are variable parts of a URL path. They are typically used to point to a specific resource within a collection, such as a user identified by ID. A URL can have several path parameters, each denoted with curly braces { } .
There is no built in simple way to do this, however, it is not hard to do.
This is how I do it, without adding a particular library. It is placed in a function so that you can invoke a simple getCode() function within your request handler.
Basically you just split the r.URL.Path into parts, and then analyse the parts.
// Extract a code from a URL. Return the default code if code // is missing or code is not a valid number. func getCode(r *http.Request, defaultCode int) (int, string) { p := strings.Split(r.URL.Path, "/") if len(p) == 1 { return defaultCode, p[0] } else if len(p) > 1 { code, err := strconv.Atoi(p[0]) if err == nil { return code, p[1] } else { return defaultCode, p[1] } } else { return defaultCode, "" } } If you love us?
