如何使用Play Framework 2.2（Java）进行同步WS调用 [英] How to make a synchronous WS call with Play Framework 2.2 (Java)

问题描述

我正在寻找一个例如这个但同步通话的例子。我的程序需要来自外部源的数据，应该等到响应返回（或直到超时）。

I'm looking for an example like this but with a synchronous call. My program needs data from external source and should wait until response returns (or until timeout).

推荐答案

你所能做的就是阻止调用等待，直到获得超时响应为止。

All you can do is just block the call wait until get response with timeout if you want.

WS.Response response = WS.url(url)
                    .setHeader("Authorization","BASIC base64str")
                    .setContentType("application/json")
                    .post(requestJsonNode)
                    .get(20000); //20 sec

JsonNode resNode = response.asJson();
