小编Uba*_*dah的帖子

我试图在开发模式下在HTTPs上运行play framework 2.2.1应用程序.我使用以下命令:

Development/Play/ssltest$ JAVA_OPTS=-Dhttps.port=9443 play run

我得到了以下,这似乎没问题

--- (Running the application from SBT, auto-reloading is enabled) ---

[info] play - Listening for HTTP on /0:0:0:0:0:0:0:0:9000
[info] play - Listening for HTTPS on port /0:0:0:0:0:0:0:0:9443

(Server started, use Ctrl+D to stop and go back to the console...)    

但是,当我尝试通过HTTPS连接到应用程序时:

"https://localhost:9443"

应用程序崩溃,我进入以下一堆例外:

[error] play - Error loading fake key store
java.security.cert.CertificateException: Subject class type invalid.

我有一个控制器动作,我需要调用第三方Web服务.

我的问题是我没有打电话给一个网络服务.我需要链接4到5个Web服务.我调用的每个Web服务都返回一个我需要处理的JSON对象,并根据一些逻辑决定调用另一个Web服务(来自4个Web服务)或者向调用者返回响应.这是我想要做的:

 public static Promise<Result> accounts(){
    return WS.url("url1").get().map(response1 -> {
        JsonNode mynode = response1.asJson();

        if (mynode.get("status").asInt()==200){
            Promise<JsonNode> jsonPromise = WS.url("url2").get().map(response2->{
                    return response2.asJson();
            });
        }

        return ok(mynode);
        }); 
}

现在,从文档中,我认为我需要的是链接每个Web服务调用是承诺的承诺.但我不知道该怎么做？

谢谢
