Question

我正在尝试使用Javascript websockets连接到Java servlet，但是onError函数总是被调用，并且没有提供太多信息。我的javascript：

var webSocket = new WebSocket('ws://localhost:8080/test');

webSocket.onerror = function(event) {
  onError(event);
};

webSocket.onclose = function(event) {
    onClose(event);
};

webSocket.onopen = function(event) {
  onOpen(event);
};

webSocket.onmessage = function(event) {
  onMessage(event);
};

function onClose(event) {
    var code = event.code;
    var reason = event.reason;
    var wasClean = event.wasClean;
    alert(code + "; " + reason + "; " + wasClean);
}

function onMessage(event) {
    //do stuff
}

function onOpen(event) {
  webSocket.send('opening socket');
}

function onError(event) {
  alert(event.message);
}

对于我的servlet，我有

@ServerEndpoint("/test")
public class TranscoderSNSServlet extends HttpServlet {

    ...
}

我能找到的唯一有用的错误代码是event.code = 1006，event.wasClean = false。我使用的浏览器肯定支持websockets。我试图在ElasticBeanstalk上运行它。任何帮助表示赞赏

Javascript中的WebSocket没有连接到servlet
