TypeError：str（）最多使用1个参数（给定2个，TypeError：需要一个整数）

Question

我正在尝试通过http://myipaddr:50997/notExisted.html访问不存在的文件类型但我收到以下错误。有人可以向我解释吗？


    from socket import *
    serverPort = 50997

    serverSocket = socket(AF_INET, SOCK_STREAM)         

    serverSocket.bind(("", serverPort))

    serverSocket.listen(1)

    # Server should be up and running and listening to the incoming    connections
    while True:
    print ("Ready to serve...")

        # Set up a new connection from the client
        connectionSocket, addr = serverSocket.accept()

        try:
            # Receives the request message from the client
            message =  connectionSocket.recv(1024)
            print ("Message is: "), message

            filename = message.split()[1]
            print ("File name is: "), filename

            f = open(filename[1:])

            outputdata = f.read()
            connectionSocket.send("HTTP/1.1 200 OK

")

    for i in range(0, len(outputdata)):  
        connectionSocket.send(outputdata[i])
    connectionSocket.send("
")

    # Close the client connection socket
    connectionSocket.close()

except IOError:
    # Send HTTP response message for file not found
    connectionSocket.send("HTTP/1.1 404 Not Found

")
    connectionSocket.send("<html><head></head><body><h1>404 Not Found</h1></body></html>
")
    # Close the client connection socket
    connectionSocket.close()

    serverSocket.close()

我得到的错误。

connectionSocket.send(bytes("HTTP/1.1 404 Not Found

","UTF-8"))
TypeError: str() takes at most 1 argument (2 given)

当我尝试删除bytes（）时出现此错误；

Traceback (most recent call last):
  File "tcpServer.py", line 26, in <module>
    connectionSocket.send("HTTP/1.1 404 Not Found

","UTF-8")
TypeError: an integer is required
