javascript - 如何在 chrome websocket 代码中接收 TLS 握手错误

Question

https://developer.mozilla.org/en-US/docs/Web/API/CloseEvent

1015    TLS Handshake   Reserved. Indicates that the connection was closed due to a failure to perform a TLS handshake (e.g., the server certificate can't be verified).

请参阅：浏览器兼容性
示例 chrome（版本 71.0）返回 1006 错误，firefox（版本 64.0（64 位））1015：

<script>
try{
    var websocket = new WebSocket("wss://self-signed.badssl.com/");

    websocket.onopen = function (event) {

    };
    websocket.onclose = function (event) {
        var reason;
        alert(event.code);

    };
    websocket.onmessage = function (event) {

    };
    websocket.onerror = function (event) {

    };
    }
    catch(err){
    document.getElementById("demo").innerHTML = err.message;
    }
</script>
<p id="demo"></p>
