Parse query parameter /hello?name=username

[abhijitkadam]

I am not sure email for help is mentioned or there is a mailing list for this project.

How do parse query parameter? Like I have /hello?name=abhijit the for this pattern I should get "abhijit" when I read from ps.ByName("name"), however unable to read

The router matches against the request method and the requested URL path only. ?name=abhijit is the URL query and not part of the URL path.

You can get the query parameter values e.g. this way:

func Hello(w http.ResponseWriter, r *http.Request, ps httprouter.Params) {
    queryValues := r.URL.Query()
    fmt.Fprintf(w, "hello, %s!\n", queryValues.Get("name"))
}

How to write the router? the followed code does NOT work??
<code
router.GET("/hello?name=xxx", Hello)

[julienschmidt]

router.GET("/hello", Hello), then use

func Hello(w http.ResponseWriter, r *http.Request, ps httprouter.Params) {
    queryValues := r.URL.Query()
    fmt.Fprintf(w, "hello, %s!\n", queryValues.Get("name"))
}

The URL query is NOT part of the URL path. The router only matches against the request method and the path.

Thanks for quick response. Gratitude.

But after looking through the README and testing, the router should go like this

router.GET("/hello/*filepath", Hello)


then to parse the URL. It works.

when i tried to get

v := r.URL.Query()

it omittted the + sign from email .

@preetamyadav Just must query-escape values first before using them in an URL query. + is used to escape spaces: https://play.golang.org/p/2o1jCP3Ut7
