Question

使用套接字创建一个简单的python Web服务器，开始了解它们是如何工作的，但我想我已经迷失了。
我的python服务器应该访问同一目录中的基本html文件，并在每次请求时显示一次。但是这段代码由于某种原因发送请求3到5次......

from socket import *
server = socket(AF_INET, SOCK_STREAM)
port = 12030
server.bind((gethostname(), port))
server.listen(1)
while True:
    print 'Ready to serve'
    conection,  addr = server.accept()
    try:
        print 'Working'
        message = conection.recv(1024)
        filename = message.split()[1] #cuts off the '/' in the request page
        f = open(filename[1:])
        print message
        outputdata = f.read()
        print outputdata
        conection.send('HTTP/1.1 200 OK\r\n')
        for i in range(0, len(outputdata)):
            conection.send(outputdata[i])
        conection.close()
    except IOError:
        print 'IO ERROR'
        print message
        print outputdata
        conection.close()
    except KeyboardInterrupt:
        server.close()
        conection.close()
        break;

这是我在浏览器中打开页面的输出。

我尝试添加server.listen(1) 和conection.send("Content-Type:text/html\r\n")，但这些都没有做任何事情。除了阻止每分钟可以请求多少次之外，我不确定问题是什么？

每次更新以打印消息

您的浏览器似乎正在请求favicon.ico。尝试将favicon.ico添加到您的文档根目录，或者尝试使用其他浏览器。这个问题不是因为你的脚本。

Python Socket Server发送文件请求3次而不是一次？
