Go: Get Query Parameters From the URL / URI

The low-API approach isn't to use the web package but the http package to accomplish this.

http://localhost:8080/cmd?foo=My_Param_Value&bar=Query_Parameters

// ..

import http

// ..

func cmd(w http.ResponseWriter, r *http.Request) {

    c := appengine.NewContext(r)

    c.Logf("r.URL.Path: " + r.URL.Path)

    c.Logf("r.FormValue(\"foo\"): " + r.FormValue("foo"))

    c.Logf(r.FormValue("bar"))

    c.Logf("r.URL.RawQuery: " + r.URL.RawQuery)

}

// ..

...and the output is:

 

2011/05/14 12:26:11 r.URL.Path: /cmd
2011/05/14 12:26:11 r.FormValue("foo"): My_Param_Value
2011/05/14 12:26:11 query_parameters
2011/05/14 12:26:11 r.URL.RawQuery: foo=My_Param_Value&bar=query_parameters
