我想运行一个component具有一定角色的。但是每次我为我的组件设置“角色”参数时，Crossbar 服务器的运行就像其中有一个无限循环：我第一次进入页面时，一切正常，但是如果我刷新或打开另一个窗口到同一页面或即使另一个客户端打开此页面，该页面也会一遍又一遍地加载......

然后，如果我停止交叉开关服务器，我会在日志中多次显示此消息：[Controller 4422] waiting for 4433 to exit...

这是我的 conf.json：

{
  "controller": {
  },
  "workers": [
    {
      "type": "router",
      "options": {
        "pythonpath": [".."]
      },
      "realms": [
        {
          "name": "realm1",
          "roles": [
            {
              "name": "anonymous",
              "permissions": [
                {
                  "uri": "*",
                  "publish": true,
                  "subscribe": true,
                  "call": true,
                  "register": false
                }
              ]
            },
            {
              "name": "wamp_app",
              "permissions": [
                {
                  "uri": "*",
                  "publish": true,
                  "subscribe": true,
                  "call": true,
                  "register": true
                }
              ]
            }
          ]
        }
     ],
     "transports": [
       {
         "type": "web",
         "endpoint":{
           "type":"tcp",
           "port":8000
         },
         "paths": {
           "/": {
             "type": "wsgi",
             "module": "cyto_multihead.wsgi",
             "object": "application"
            },
            "lp": {
              "type": "longpoll"
            },
            "static": {
              "type": "static",
              "directory": "../static/"
            },
            "ws": {
              "type": "websocket"
            }
          }
        }
      ],
      "components": [
        {
          "type": "class",
          "classname": "crossbar_test.crossbar.MyComponent",
          "realm": "realm1",
          "role": "wamp_app"
        }
      ]
    }
  ]
}

我的文件是这样放置的：

my_project_directory/
  .crossbar/
    config.json
  crossbar_test/
    crossbar.py

此外，如果我不指定角色，则服务器不会以此错误启动：

我的配置有什么问题？

我认为问题来自以下配置：

"/": {
  "type": "wsgi",
  "module": "cyto_multihead.wsgi",
  "object": "application"
},

如果您更改配置，例如：

"/": {
  "type": "static",
  "directory": "../hello/web"
},

Crossbar 将成功运行。
