How to get the POST params in revel golang
问题
如何在revel中获取POST请求的参数？我有以下代码：
func (c App) Ndc() revel.Result {
fmt.Println(c.Params)
//更简单的代码返回一个json...
}
我尝试了很多方法，但都没有成功，所以我希望尽可能保持代码的简洁。这是输出结果：
&{map[Origin:[LHR] Destination:[DME] DepartureDate:[2016-10-31] ArrivalDate:[]] map[] map[] map[] map[Origin:[LHR] Destination:[DME] DepartureDate:[2016-10-31] ArrivalDate:[]] map[] []}
内容是正确的，但是...我如何逐个获取这些变量及其值呢？
谢谢。

I have tested many things but nothing works, so I prefer let the code cleaner as possible. This is the output:
&{map[Origin:[LHR] Destination:[DME] DepartureDate:[2016-10-31] ArrivalDate:[]] map[] map[] map[] map[Origin:[LHR] Destination:[DME] DepartureDate:[2016-10-31] ArrivalDate:[]] map[] []}
The content is good, but... how can I get one by one these variables and their values??
Thank you.

这取决于你的请求中的Content-Type是否设置为application/json / text/json。如果是这样的话，你需要显式地将其转换为一个映射（map）：
var j map[string]interface{}
c.Params.BindJSON(&j)
origin := j["Origin"] // 等等。
否则，以下代码应该可以工作：
origin := c.Params.Form["Origin"]
英文:
It depends on whether the Content-Type in your request is set to application/json / text/json. If so, you will need to explicitly convert it to a map:
var j map[string]interface{}
c.Params.BindJSON(&j)
origin := j["Origin"] // etc.
Otherwise this should work:
origin := c.Params.Form["Origin"]

这只是一个简单的映射，所有的值都在一个切片中。要从请求中获取Origin的值：
c.Params.Get("Origin")
**编辑：**上述方法不起作用，但这个应该可以：
c.Params.Get("Origin")
英文:
It's all just a simple map and all values are in an slice. To get the Origin value from the request:
<!-- language: go -->
c.Params["Origin"][0]
EDIT: The above does not work, but this should:
<!-- language: go -->
c.Params.Get("Origin")

最后我找到了一个答案，不知道是否是最好的方法。按照这篇帖子的步骤，我找到了解决方案：
fmt.Println(c.Request.Form["Origin"][0])
输出结果是LHR。

Finally I find an answer, I don't know if it is the best way. After follow step by step this post, I find the solution:
fmt.Println(c.Request.Form["Origin"][0])
The output is LHR.
