使用Java Play发送HTTP请求（WSClient初始化）

下面的代码取自定义客户端类的官方Play 2.6文档

import javax.inject.Inject;
import play.libs.ws.*;
import java.time.Duration;
import java.time.temporal.ChronoUnit;
import java.util.concurrent.CompletionStage;

public class MyClient implements WSBodyReadables, WSBodyWritables {
    private WSClient ws;

    @Inject
    public MyClient(WSClient ws) {
        this.ws = ws;
        sendRequest();
    }

    public void sendRequest() {
        WSRequest request = ws.url("http://example.com");

        WSRequest complexRequest = request.addHeader("headerKey", "headerValue")
                .setRequestTimeout(Duration.of(1000, ChronoUnit.MILLIS))
                .addQueryParameter("paramKey", "paramValue");

        CompletionStage<? extends WSResponse> responsePromise = complexRequest.get();
    }
}

必须注入它，就像在MyClass中一样：

如果有一些问题不允许您使用此ex，您无法控制演员的创建方式，请在您的问题中添加更多信息。

之前，我是这样实例化MyActor的：return WebSocket.Text.acceptrequest->ActorFlow.actorRefMyActor:：props，actorSystem，materializer；这已经不起作用了，那么我该怎么做呢？然后我想你可以在创建actor时注入Cyclient对象，然后不用MyActor:：props，而是使用props.createMyActor.class，即\u MYCLIENT的\u注入的\u实例。

public void onReceive(Object message) throws Exception {
    if (message instanceof String) {
        out.tell("I received your message: " + message, self());
        MyClient a = new MyClient(); //problem here
    }
}

public class MyActor extends UntypedAbstractActor {

    private MyClient client;

    @Inject
    public MyActor(MyClient client) {
        this.client = client;
    }

    @Override
    public void onReceive(Object message) throws Exception {
        client.sendRequest();
    }
}
