英文:
how to correctly pattern match with routers handleFunc?
问题
我正在使用gorilla web toolkit和golang，并且有以下的代码：
func test(w http.ResponseWriter, r *http.Request) {
fmt.Println("test was called ..")
}
func main() {
runtime.GOMAXPROCS(runtime.NumCPU())
mx := mux.NewRouter()
mx.HandleFunc(?, test)
http.ListenAndServe(":8080", mx)
}
我的服务器将提供一个包含表单的HTML文档，该表单将执行一个GET请求并发送"/?id={something}"。我该如何设置mx.HandleFunc中的模式以匹配查询，以便调用test函数？
我尝试过以下方式：
- "/?id={something}"
- "/?id="
- mx.HandleFunc("/", test).Queries("id")
- mx.HandleFunc("/", test).Methods("POST")（最后一个我更改了相应的页面代码，使表单进行POST请求）

mx.HandleFunc(?, test)
http.ListenAndServe(":8080", mx)
}
My server will serve a html-document with a form that will do a get-request and send a "/?id={something}". How can I set up a pattern in the mx.HandleFunc to match the query so that test is called?
I have tried:
"/?id={something},
"/?id=",
mx.HandleFunc("/", test).Queries("id")
mx.HandleFunc("/", test).Methods("POST")
(the last one I changed the corresponding page code so that form makes a post instead).

当使用.Queries()时，你需要给它提供一个键和一个值，例如：
mx.HandleFunc("/", test).Queries("id", "value")
你还可以将模式用作值，例如：
mx.HandleFunc("/", test).Queries("id", "{id:[0-9]+}")
详细信息请参见这里：http://godoc.org/github.com/gorilla/mux#Route.Queries
英文:
When using .Queries() you need to give it both a key and a value, like:
mx.HandleFunc("/", test).Queries("id", "value")
You can also use a pattern as the value, like:
mx.HandleFunc("/", test).Queries("id", "{id:[0-9]+}")
