首先客户端与服务端都要先生成socket对象,创建socket实例。 然后服务端通过bind函数绑定端口,并进行监听,服务端再使用accept方法进入阻塞状态,等待一个连接的到来 客户端使用connect函数通过以元组形式传入一个IP地址与端口号,与服务端建立连接 客户端读取用户的输入,我们可以判断一下,如果这串字符以get开头,那么就把get...

With Python 3.2, an alternative approach becomes available: extension modules which restrict themselves to a limited API (by defining Py_LIMITED_API) cannot use many of the internals, but are constrained to a set of API functions that are promised to be stable for several releases. As a conse...

FTP FTP is a protocol used for remote file transfer. If you plan to make your FTP server publicly available, enable this option. You need the vsftpd package installed for this option to be useful. 1. 2. 3. 4. 5. 每一个服务定义都需要一个简短的名字、描述和端口网络用于指定需要使用的协议...
