第三个参数timeout可以用来设置连接超时设置。 如果超过timeout的指定的时间,连接没有完成,会返回超时错误。 1.2 读写超时 在Conn定义中,包括读写的超时时间设置。 type Conninterface{//SetDeadline sets the read and write deadlines associated//with the connection. It is equivalent to calling both//SetRead...

●type 包括 static type和concrete type.简单来说 static type是你在编码是看见的类型(如int、string), concrete type是runtime系统看见的类型 ●类型断言能否成功,取决于变量的concrete type,而不是static type.因此,一个 reader变量如果它的concrete type也实现了write方法的话,它也可以被类型断言为writer. ...
net.http.(c * conn).serve方法是Golang sdk解析处理HTTP请求的主函数,我们可以找到WriteTimeout的设置入口,c.rwc.SetWriteDeadline。这里的rwc类型为net.Conn,是一个接口。真正的对象是由l.Accept()返回的,而l是对象TCPListener。往下追踪可以发现创建的是net.TCPConn对象,而该对象继承了net.conn,net....
