javascript - WebSocket 握手错误 : Unexpected response code: 500

Question

我在我的网站上使用 websocket，但它随机向我发送以下错误消息:

WebSocket connection to 'ws://client.mydomain.com/socket.io/?EIO=3&transport=websocket&sid=4Kbec5T_XStAC949AACS' failed: Error during WebSocket handshake: Unexpected response code: 500

这是我在我的应用程序中连接到 websocket 的方式(注意它是一个 Angular 应用程序)。

    app.factory('clientSocket', ['$sessionStorage', 'socketFactory', function ($sessionStorage, socketFactory) {
    var connection = '';
    $.ajax({
        url: 'config.json',
        async: false,
        dataType: 'json',
        success: function (response) {
            connection = response.app_url;
        }
    });
    var myIoSocket = io.connect(connection);

    var clientSocket = socketFactory({
        ioSocket: myIoSocket
    });
    clientSocket.forward('someEvent');

    clientSocket.on('connect', function () {
        if ($sessionStorage.activeUser != null) {
            clientSocket.emit('userData', $sessionStorage.activeUser.user);
        }
    });


    return clientSocket;
}]);

我不太确定问题出在哪里，但基本上连接字符串如下所示:

http://client.mydomain.com

谁能告诉我这是怎么回事？

您不能通过将其余代码添加到 ajax 的成功回调中来尝试一下吗？像这样:

app.factory('clientSocket', ['$sessionStorage', 'socketFactory', function ($sessionStorage, socketFactory) {
var connection = '';
$.ajax({
    url: 'config.json',
    async: false,
    dataType: 'json',
    success: function (response) {
        connection = response.app_url;
        var myIoSocket = io.connect(connection);

        var clientSocket = socketFactory({
    ioSocket: myIoSocket
});
clientSocket.forward('someEvent');

clientSocket.on('connect', function () {
    if ($sessionStorage.activeUser != null) {
        clientSocket.emit('userData', $sessionStorage.activeUser.user);
    }
});


return clientSocket;
    }
});
