快速NSSocket编程/python教程修复

Question

我对python几乎一无所知，但我正在尝试学习关于NSSockets的一个教程，它使用Python。这是python脚本。脚本是用python2编写的，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，但是当我试图连接我的Swift代码时，它会与这条消息一起崩溃。

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

抱怨我发送的数据格式错误；这是发送消息的快速代码。

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

我怎么才能治好巨蟒和巨蟒呢？我正在努力学习/翻译的教程已经出版了。

Answer 1

多亏了https://stackoverflow.com/users/1076479/gil-hamilton链接，我终于找到了我正在看的东西。解决方案。我使用的是我在这里发布的相同的快速代码，我删除了python的最后一节。我正在发送和接收这个。

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

现在我知道了问题的所在，用巨蟒我可以找到答案！我基本上在python脚本中删除了这个。

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')

用这个代替它..。

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

太简单了，太蠢了.
