我们再用一个processConnection(Socket clientSocket)方法处理我们的连接 由于我们的TCP传输是以流的形式传播的,所以我们这里用到了读写数据流的方法来进行书写,不会这一部分的小伙伴,可以去看看博主所写《【JavaEE初阶】 文件内容的读写 —— 数据流》进行查看学习 接下来我们书写这个processConnection(Socket clientSo...

Target Server:TCP采样器中填写服务器地址、端口。Connect:设置连接超时时间。Response:设置响应超时时间。Re-use connection:表示重复使用该连接发送请求。Close connection:表示每次发送完该条数据后,关闭连接。End of line(EOL) byte value:终止符。 比如,在我的项目中返回值转为 16 进制的时候如下: 7e80010005010001...
The combination of this information, including sockets, sequence numbers, and window sizes, is called a connection. 简单来说就是,用于保证可靠性和流量控制维护的某些状态信息,这些信息的组合,包括Socket、序列号和窗口大小称为连接。 所以我们可以知道,建立一个 TCP 连接是需要客户端与服务器端达成上述三个...
