Take a look into play.mvc.Httpclass, you have some options there (depending on data format) i.e.
看看play.mvc.Http课堂，你有一些选择（取决于数据格式）即
RequestBody body = request().body();
MultipartFormData formData = request().body().asMultipartFormData();
Map<String, String[]> params = request().body().asFormUrlEncoded();
JsonNode json = request().body().asJson();
String bodyText = request().body().asText();
You can test request().body().asText()i.e. using cUrl from commandline:
您可以request().body().asText()从命令行使用 cUrl进行测试：
curl -H "Content-Type: text/plain" -d 'Hello world !' http://domain.com/your-post-action
... or using some tool, like browser plugin: https://chrome.google.com/webstore/detail/advanced-rest-client/hgmloofddffdnphfgcellkdfbfbjeloo

If you call the following code on a request;
如果您根据请求调用以下代码；
String bodyText = request().body().asText();
bodyText will be null if the Content-Type header is application/json
如果 Content-Type 标头是 application/json，bodyText 将为 null
There isn't a way using the provided controller APIs to just get JSON text if the Content-Type header is application/json without first converting to a JsonNode
如果 Content-Type 标头是 application/json 而不先转换为 JsonNode，则无法使用提供的控制器 API 来获取 JSON 文本
So the best way to do this if the application/json is your Content-Type header is
因此，如果 application/json 是您的 Content-Type 标头，那么执行此操作的最佳方法是
String bodyText = request().body().asJSON().toString();
This is a fail on play framework's part, because they should just have a method to get the request body as a String no matter what the Content-Type header is.
这对 play 框架来说是一个失败，因为无论 Content-Type 标头是什么，他们都应该有一种方法来将请求正文作为字符串获取。

With Play Framework 2.3 it is possible to get raw json text even is Content-Type header is application/json
使用 Play Framework 2.3，即使 Content-Type 标头是 application/json，也可以获得原始 json 文本
def postMethod = Action(parse.tolerantText) { request =>
val txt = request.body
}

It will give request JSON body as string. I tested it on play 2.6.xval body = request.body.asJson.get.toString()
它将以字符串形式提供请求 JSON 正文。我在 play 2.6.x 上测试过val body = request.body.asJson.get.toString()
