Amazon web services 如何建立到AWS设备场远程会话终结点的连接

我尝试创建AWS设备场远程会话，我能够成功地做到这一点。创建的远程会话的响应JSON具有端点（wss）和主机地址（IP）。而不是登录到AWS设备场与设备交互。我想直接在我自己的网页上提供远程访问（我不确定这是否可能）。希望它可以在画布标记下呈现

虽然我没有套接字方面的经验，但我只是尝试了一些示例代码来连接收到的Web套接字URL

var wsUri = "wss://devicefarm-interactive.us-west-2.amazonaws.com/?X-Amz-Date=*&X-Amz-Credential=*&X-Amz-Algorithm=*&X-Amz-SignedHeaders=host&X-Amz-Signature=*&X-Amz-Security-Token=*";
var websocket = new WebSocket(wsUri);
websocket.send('ping');

下面是控制台上的错误。 连接在收到握手响应之前关闭

---

任何要实现的示例链接都会有帮助

我能够重现该错误。在chrome中检查页面后（因为它内置了一个web套接字调试器），我寻找了使用networking选项卡使用web套接字连接的示例，该示例将显示以下内容：

基本上，它的工作原理是不断地向我们发送图像流

当我复制为cURL命令时，这就是结果

执行以下CLI命令时，我恢复了端点：

稍后我需要花更多的时间在这方面，但我认为其中的一些内容很有帮助，所以我发布了它
