Question

我想运行一个具有特定角色的component。但每次我设置＆＃34;角色＆＃34;我的组件的参数Crossbar服务器运行就像它有一个无限循环：我第一次进入页面，一切都很完美，但如果我刷新或打开另一个窗口到同一页面，或者即使另一个客户打开此页面，页面一遍又一遍地加载......

然后，如果我停止横杆服务器，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"
        }
      ]
    }
  ]
}

我的文件放置如下：

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

此外，如果我没有指定角色，则服务器不会从此错误开始：

我的配置有什么问题？

Answer 1

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。

将角色关联到Crossbar组件
