Kubernetes下端口443上带有/socket.io的websocket无法正常工作

标签: python flask websocket kubernetes minikube

试图将我的开发环境移至可在minikube上运行。

页面已加载,但我的页面在与index.html加载相同的端口/协议上使用了websocket(在本例中为https),并且websocket似乎无法正常工作。

这是在本地开发盒中通过nginx / python运行时正确输出的示例。

注意每5秒有一个GET(这是页面上运行的计时器)

在Kubernetes上运行时,页面加载并且计时器显示为websocket正常工作,但是我没有显示任何日志,其中websocket在初始位置之后具有GET或POST。

Ingress的设置如下:

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: ingress-service
  annotations:
    kubernetes.io/ingress.class: nginx
spec:
  rules:
    - http:
        paths:
          - path: /
            backend:
              serviceName: websitev2-cluster-ip-service
              servicePort: 8080

如前所述,websocket不在其他端口上,并且在javascript中实例化为:

namespace = '/socket';
var socket = io.connect(location.protocol + '//' + document.domain + ':' + location.port + namespace);

是否有使Websocket正常工作的特殊要求?我不认为我需要特殊的路由,因为URI需要与其他所有文件都发送到相同的位置,并且发送到同一端口。

编辑:更多详细信息

我的网站有一个表单,提交后将执行以下代码:

    $('form#job').submit(function(event) {
        var nameValue = JSON.stringify($(event.target).serializeArray());
        console.log(nameValue)
        socket.emit('job_submit', {data: nameValue});
        return false;
    });

在python端,我有我的套接字代码,一旦用户单击“提交”按钮,该代码就会被点击。

@socketio.on('job_submit', namespace='/socket')
def job_submit(message):
    print('recieved job_submit message from client')
    # kick off subjob in celery task
    data = unstringify(message)
    print('data = {0}'.format(data))
    sessiondata = dict(session)
    print('sessiondata = {}'.format(sessiondata))
    subjobstart.delay(sessiondata, request.sid, data)

在我的日志中,当单击“提交”按钮时,我没有收到任何“从客户端收到的job_submit消息”消息,这意味着javascript试图将websocket发射发送至python服务器,但消息从未到达那里。

随着网站上时间的更新,从python到客户端页面的发射正在工作。
