Playframework Java中的POST请求

Question

Hi In my playframework application I want to do a simple Post request.

So I defined in my Route this:

POST        /printName                              @controllers.Index.printName()

Same way I do it in scala.

Then I have the following controller function:

public Result printName(Http.Request request) {
    JsonNode json = request.body().asJson();
    return ok("Got name: " + json.get("name").asText());
}

So now compiler returns:

missing arguments for method printName in class Index; follow this method with `_' if you want to treat it as a partially applied function

When I add the parameter in The route like this:

POST        /printName                  @controllers.Index.printName(request: Request)

Then I got this error

not found: type Request

How would it be correct? Example is from Playframework page: https://www.playframework.com/documentation/2.7.x/JavaBodyParsers#The-default-body-parser

Thanks in advance.

I found the solution:

controller function

public Result printName() {
    Http.Request request = request();
    JsonNode json = request.body().asJson();
    return ok("Got name: " + json.get("name").asText());
}

and the route

POST        /printName              @controllers.Index.printName()
