Question

我试图从与python服务器通信的javascript客户端创建一个Websocket。

我的服务器是这样的：

connexions_asked, wlist, xlist = select.select([connexion_principal], [], [], 0.05)

for connexion in connexions_asked:
    connexion_with_client, infos_connexion = connexion.accept()
    clients_connected.append(connexion_avec_client)
    initCo = clients_connected[-1].recv(1000)
    initCo = initCo.decode()
    initCo = initCo.split("\n")
    secWebSocketKey = ""
    for line in initCo:
        if "Sec-WebSocket-Key" in line:
            secWebSocketKey = line
            break;
    secWebSocketKey = secWebSocketKey.split("Sec-WebSocket-Key: ")[1]
    magicStr = "258EAFA5-E914-47DA-95CA-C5AB0DC85B11"

    list_of_letters = list()
    for letter in secWebSocketKey:
        list_of_letters.append(letter)
    list_of_letters.pop(-1)
    for letter in magicStr:
        list_of_letters.append(letter)

    secWebSocketKey = "".join(list_of_letters)

    secWebSocketKey = secWebSocketKey.encode()
    sha1 = hashlib.sha1(secWebSocketKey).digest()
    sha1 = base64.b64encode(sha1)
    clients_connected[-1].send(b'HTTP/1.0 101 Switching Protocols\n')
    clients_connected[-1].send(b'Content-Type: text/html\n')
    clients_connected[-1].send(b'Connection: upgrade\n')
    clients_connected[-1].send(b'Upgrade: websocket\n')
    clients_connected[-1].send(b'Sec-WebSocket-Accept: ')
    clients_connected[-1].send(sha1)
    clients_connected[-1].send(b'\n')
    clients_connected[-1].send(b'\n')
    clients_connected[-1].send(b"<html><body><h1>Hello World</h1> this is my server!</body></html>")

我的js客户端是这样的：

var exampleSocket = new WebSocket("ws://localhost:12800");

exampleSocket.onopen = function (event) {
    console.log("I'm connected");
};

exampleSocket.onmessage = function (event) {
    console.log(event.data);
}

function sendMsg(str){
    exampleSocket.send(str);
}

当我打电话给我的服务器时，一切似乎都有效，我可以找到＆＃34;我已连接＆＃34;在我的控制台上，但它引发了一个特殊的错误：

websocket.js：1 WebSocket连接到＆＃39; ws：// localhost：12800 /＆＃39;失败：一个或多个保留位开启：reserved1 = 0，reserved2 = 1，reserved3 = 1

我真的不知道它来自哪里。通过在互联网上搜索，我发现它可能来自对网络协议的过滤，但我不知道如何操纵它。

是否有人使用WebSockets出现此问题？

错误：WebSocket连接到＆＃39; ws：// localhost：12800 /＆＃39;失败：一个或多个保留位开启：reserved1 = 0，reserved2 = 1，reserved3 = 1
