本文整理汇总了Golang中github.com/ghedo/go/pkt/packet.Packet类的典型用法代码示例。如果您正苦于以下问题:Golang Packet类的具体用法?Golang Packet怎么用?Golang Packet使用的例子?那么恭喜您, 这里精选的类代码示例或许可以为您提供帮助。
在下文中一共展示了Packet类的4个代码示例,这些例子默认根据受欢迎程度排序。您可以为喜欢或者感觉有用的代码点赞,您的评价将有助于系统推荐出更棒的Golang代码示例。
示例1: SetPayload
func (p *Packet) SetPayload(pl packet.Packet) error {
p.pkt_payload = pl
p.Protocol = TypeToProtocol(pl.GetType())
p.Length = p.GetLength()
pl.InitChecksum(p.pseudo_checksum())
return nil
}
示例2: Answers
func (p *Packet) Answers(other packet.Packet) bool {
if other == nil || other.GetType() != packet.ICMPv6 {
return false
}
if other.(*Packet).Type == EchoRequest && p.Type == EchoReply {
return true
}
return false
}
示例3: FindLayer
// Return the first layer of the given type in the packet. If no suitable layer
// is found, return nil.
func FindLayer(p packet.Packet, layer packet.Type) packet.Packet {
switch {
case p == nil:
return nil
case p.GetType() == layer:
return p
default:
return FindLayer(p.Payload(), layer)
}
}
示例4: UnpackAll
// Recursively unpack the given byte slice into a packet. The link_type argument
// must specify the type of the first layer in the input data, successive layers
// will be detected automatically.
//
// Note that unpacking is done without copying the input slice, which means that
// if the slice is modifed, it may affect the packets that where unpacked from
// it. If you can't guarantee that the data slice won't change, you'll need to
// copy it and pass the copy to UnpackAll().
func UnpackAll(buf []byte, link_type packet.Type) (packet.Packet, error) {
var b packet.Buffer
b.Init(buf)
