HTTP客户端，空闲超时

HTTP客户端，空闲超时

您需要创建自己的

net.Dialer

，并返回，以

net.Conn

设置适当的读写期限。

该

Conn

会是这个样子：

// Conn wraps a net.Conn, and sets a deadline for every read// and write operation.type Conn struct {    net.Conn    ReadTimeout  time.Duration    WriteTimeout time.Duration}func (c *Conn) Read(b []byte) (int, error) {    err := c.Conn.SetReadDeadline(time.Now().Add(c.ReadTimeout))    if err != nil {        return 0, err    }    return c.Conn.Read(b)}func (c *Conn) Write(b []byte) (int, error) {    err := c.Conn.SetWriteDeadline(time.Now().Add(c.WriteTimeout))    if err != nil {        return 0, err    }    return c.Conn.Write(b)}
