python - Swift NSSocket 编程/python 教程修复

Question

我对 Python 几乎一无所知，但我正在尝试快速学习 NSSockets 教程；并且使用python。这是 python 脚本。脚本在 python2 中，但我必须在 python 3 下运行它。

from twisted.internet.protocol import Factory, Protocol
from twisted.internet import reactor

class IphoneChat(Protocol):
def connectionMade(self):
    self.factory.clients.append(self)
    print("clients are ", self.factory.clients)

def connectionLost(self, reason):
    self.factory.clients.remove(self)

def dataReceived(self, data):
    a = data.split(':')
    print(a)
    if len(a) > 1:
        command = a[0]
        content = a[1]

        msg = ""
        if command == "iam":
            self.name = content
            msg = self.name + " has joined"

        elif command == "msg":
            msg = self.name + ": " + content
            print(msg)

        for c in self.factory.clients:
            c.message(msg)

def message(self, message):
     self.transport.write(message + '\n')


factory = Factory()
factory.protocol = IphoneChat
factory.clients = []
reactor.listenTCP(80, factory)
print("Iphone Chat server started")
reactor.run()

它可以工作，但是当我尝试连接我的 Swift 代码时，它会因这条消息而崩溃。

File "server.py", line 13, in dataReceived
a = data.split(':')
builtins.TypeError: a bytes-like object is required, not 'str'

提示我发送的数据格式不对；这是发送消息的 swift 代码。

func sayhello() {
    let response = String(format:"iam:brian")
    let dataToSend = [UInt8](response.utf8)
    outputStream?.write(dataToSend, maxLength: dataToSend.count)
}

如何修复 swift 或 python？我尝试遵循/翻译的教程在里面。

感谢https://stackoverflow.com/users/1076479/gil-hamilton链接 我设法弄清楚我在看什么。解决方案。我使用的是与此处发布的相同的 swift 代码，我删除了 python 的最后一部分。我正在发送和接收这个。

Iphone Chat server started
clients are  [<__main__.IphoneChat object at 0x1035039e8>]
b'iam:brian'

现在我知道问题出在哪里了，用python我可以找到答案!我基本上在 python 脚本中删除了它。

def dataReceived(self, data):
a = data.split(':')
print(a)
if len(a) > 1:
    command = a[0]
    content = a[1]

    msg = ""
    if command == "iam":
        self.name = content
        msg = self.name + " has joined"

    elif command == "msg":
        msg = self.name + ": " + content
        print(msg)

    for c in self.factory.clients:
        c.message(msg)

def message(self, message):
 self.transport.write(message + '\n')

并用这个替换它......

def dataReceived(self, data):
    print(data)
    dumb=data.decode('utf8')
    print(dumb)

它是如此简单，它是愚蠢的....
