步骤1:导入socket模块 我们首先要导入 Python 的 socket 模块,以便在代码中使用它的功能。 importsocket# 导入socket模块 1. 步骤2:创建socket对象 接下来,我们需要创建一个 socket 对象,这是进行网络通信的基础。 # 创建一个 TCP/IP socketsock=socket.socket(socket.AF_INET,socket.SOCK_STREAM)# 使用 IPv4 和...
pythonsocket缓冲区不足python清空socket缓冲区 1.缓冲区:作用:将程序和网络解耦分为输入缓冲区, 输出缓冲区每个 socket 被创建后,都会分配两个缓冲区,输入缓冲区和输出缓冲区。write()/send() 并不立即向网络中传输数据,而是先将数据写入缓冲区中,再由TCP协议将数据从缓冲区发送到目标机器。一旦将数据写入到缓冲...

For instance, when we perform text pattern matching in Python, we create pattern objects, and when we perform network scripting, we use socket objects. These other kinds of objects are generally created by importing and using modules and have behavior all their own. As we’ll see in later ...
