在javascript中，我只是尝试连接：

var location = window.location
var socket = new WebSocket('ws://' + location.host + ':9001' + location.pathname)
socket.onopen = function(e){
    console.log('open', e)
}
socket.onerror = function(e){
    console.log('error', e)
}
socket.onclose = function(e){
    console.log('close', e)
}

每次访问该页面时，它都会提供到“ws://127.0.0.1:9001/”的

WebSocket连接失败：WebSocket握手时出错：net:：ERR_connection_RESET

，并在控制台中打印错误和关闭消息。
我遵循了在提供的示例设置，并使用了一个nginx实例，但它给出了相同的错误。

似乎后端没有接收到消息，因此我认为设置中一定有一些东西，即消息队列或redis服务器。我遗漏了什么？

是的，我对一个与你类似的设置进行了相当快的故障排除。我目前正在centos 7.5服务器上同时运行channels2、daphne、redis和apache。终于可以完美地工作了

我发现使用AsyncConsumer进行故障排除更容易，提供了更多的控制。 试着做：

from channels.consumer import SyncConsumer, AsyncConsumer
class ChatConsumer(AsyncConsumer):
    async def websocket_connect(self, event):
        # when the socket connects
        print(event)
        await self.send({
            "type": "websocket.accept"
        })

然后你可以看到数据输入，如果有的话

对于apache，像你一样，我使用重写引擎。（在vhost文件中）

希望你能弄明白！

是的，我将其更改为使用SyncConsumer，似乎可以正常工作，但现在出现了另一个问题-在apache中使用此配置时，utf8文件名存在问题（直接使用daphne时-使用nginx代理websocket流量时，unicode也没有问题，仅使用apache时-出于某种原因，虽然我将其设置为utf8，但它使用ascii字符集）
