可以正确进入django管理后台，but 小程序里 爆了socket500 error

[cww97]

WebSocket connection to 'ws://172.29.222.92:8000/wsapi' failed: Error during WebSocket handshake: Unexpected response code: 500
WebSocket connection to 'ws://172.29.222.92:8000/wsapi' failed: WebSocket is closed before the connection is established.

django后台报了这个error

小程序在win上调试，server开在了同内网下的ubuntu下，不知道这个会不会是原因。but，在win下访问django管理后台无问题

[007gzs]

channels 3.0的兼容问题，最新版本已做处理

[cww97]

server端pull了新的code，再次刷新小程序里，

Uncaught (in promise) thirdScriptError
"网络错误"
String

此时django后台报错

ERROR server.application_checker Exception inside application: ERR unknown command 'BZPOPMIN'

改装了2.4版本的channels依然没有改变

[cww97]

from here,似乎

pip install channels-redis==2.4.2

了之后好了

[007gzs]

https://github.com/django/channels_redis/blob/4c4fa01c4c45b973ffc7901f482c7064e71196de/CHANGELOG.txt#L25-L28

channels-redis 要求redis版本大于5

[cww97]

创建会议室后并没有返回上一页。

手动返回上一步点开该会议室后，又报了参数错误

参数错误一直报，创建会议和预约会议之后不会正确返回，but可以正确创建
功能基本能正常使用，只是控制台里一直在报参数错误，没法正确返回也怪难受的

[cww97]

进入db后台看qr_code是空的，怀疑是二维码没有创建成功，可能是哪里引起的呢

[cww97]

请问是否可以提供一个，您成功运行的环境中各种python包的具体版本号，以及sql与redis的具体版本号
运行发现request meeting可以成功，request room的info没有返回结果
报错全在底层

[cww97]

http://xx.xx.xx.xx/api/meeting/room/info?room_id=2

使用api调试的时候，发现

HTTP 200 OK
Allow: GET, POST, HEAD, OPTIONS
Content-Type: application/json
Vary: Accept

{
    "code": -11,
    "message": "参数错误",
    "data": {
        "errors": {
            "meeting_id": [
                "该字段是必填项。"
            ]
        }
    }
}

为什么会出现，查room的info的时候需要填写meeting_id的情况

[cww97]

以及api调试的时候提示需要登录该如何临时解决

[cww97]

我注释了检测登录的两行

这个我看着也不对，但不知道为什么我线上环境竟然还能用。。你把RoomBase里的meeting_id改成room_id先试下把

最好从开发者工具里复制cookies测试
