Adding query Parameters to Go Json Rest
问题
我正在使用go-json-rest库。我试图在代码中识别查询参数，例如localhost:8080/reminders?hello=world，我想要访问{hello: world}。我有以下代码：
//在另一个函数中
&rest.Route{"GET", "/reminders", i.GetAllReminders},
func (i *Impl) GetAllReminders(w rest.ResponseWriter, r *rest.Request) {
reminders := []Reminder{}
i.DB.Find(&reminders)
w.WriteJson(&reminders)
}
我知道r.PathParams保存URL参数，但我似乎找不到如何获取URL中"?"后面的查询参数。

I am using the library go-json-rest. I'm trying to recognize queries parameters in the code for example localhost:8080/reminders?hello=world I want to access {hello: world} . I have the following code:
//in another function
&rest.Route{"GET", "/reminders", i.GetAllReminders},
func (i *Impl) GetAllReminders(w rest.ResponseWriter, r *rest.Request) {
reminders := []Reminder{}
i.DB.Find(&reminders)
w.WriteJson(&reminders)
}
I know that r.PathParams holds the url parameters but I cannot seem to find how to the query parameters past the "?" in the url.

鉴于go-json-rest只是在net/http之上的一个薄包装，你是否查看过该包的文档？具体来说，Request对象有一个字段Form，其中包含解析后的查询字符串值和POST数据，你可以将其作为url.Values（map[string][]string）访问，或者从FormValue中获取特定的值。
英文:
Given that go-json-rest is a thin wrapper on top of net/http, have you looked at that package's documentation? Specifically, the Request object has a field Form that contains a parsed map of query string values as well as POST data, that you can access as a url.Values (map[string][]string), or retrieve one in particular from FormValue.
