How to get payload from a POST in Play 2.0
提问by jglatre
I'm trying to implement a REST API with Play 2.0 (Scala) but I'm getting stuck in POST method. How do I get the payload from Request object? I haven't find any documentation about it and have been unable to figure out from source code.

You should be able to do the following:
您应该能够执行以下操作：
def index = Action { request =>
val body = request.body
}
And also things like:
还有这样的事情：
def index = Action { request =>
val name = request.queryString.get("name").flatMap(_.headOption)
Ok("Hello " + name.getOrElse("Guest"))
}

for java (with a param names java_name):
对于 java（带有参数名称 java_name）：
String name = request().body().asFormUrlEncoded().get("java_name")[0];
for scala (with a param names scala_name):
对于 scala（带有参数名称 scala_name）：
def name = request.body.asFormUrlEncoded.get("scala_name")(0)

I had to do it somewhat differently (maybe I'm on a newer version of the codebase):
我不得不做一些不同的事情（也许我使用的是较新版本的代码库）：
my javascript:
我的javascript：
$(document).ready(function(){
$.post( "/ping", {one: "one", two: "two" },
function( data ){
console.log(data); //returns {"one":"one","two":"two"}
})
});
my route:
我的路线：
POST /ping controllers.Application.ping()
My controller method:
我的控制器方法：
def ping() = Action{ request =>
val map : Map[String,Seq[String]] = request.body.asFormUrlEncoded.getOrElse(Map())
val one : Seq[String] = map.getOrElse("one", List[String]())
val two : Seq[String] = map.getOrElse("two", List[String]())
Ok(
toJson( JsObject(List( "one"->JsString(one.first), "two"->JsString(two.first))))
)
}
I assume this will change in the final version.
我认为这会在最终版本中改变。

Here is what I did.
这是我所做的。
val map : Map[String,Seq[String]] = request.body
val seq1 : Seq[String] = map.getOrElse("socket_id", Seq[String]())
val seq2 : Seq[String] = map.getOrElse("channel_name", Seq[String]())
val socketId = seq1.head
val channelName = seq2.head
