一、 socket 的创建
1、使用示例
s = socket.socket(socket.AF_INET, socket.SOCK_RAW, socket.IPPROTO_IP)
2、源码
socket(…) 的源码
def __init__(self, family=-1, type=-1, proto=-1, fileno=None):# For user code address family and type values are IntEnum members, but# for the underlying _socket.socket they're just integers. The# constructor of _socket.socket converts the given argument to an# integer automatically.if fileno is None:if family == -1:family = AF_INETif type == -1:type = SOCK_STREAMif proto == -1:proto = 0...省略三行...
二、参数说明
1、python 3.8 family的取值
AF_APPLETALK = 16 # AppleTalk
AF_DECnet = 12 # DECet protocol sockets
AF_INET = 2 # IPv4 Internet protocols
AF_INET6 = 23 # IPv6 Internet protocols
AF_IPX = 6 # Novell protocols
AF_IRDA = 26 # Socket interface over IrDA (moved to staging in Linux 4.14, removed in Linux 4.17).
AF_SNA = 11
AF_UNSPEC = 0
2、python 3.8 type的取值
SOCK_DGRAM = 2
SOCK_RAW = 3
SOCK_RDM = 4
SOCK_SEQPACKET = 5
SOCK_STREAM = 1
- SOCK_STREAM
提供有序、可靠、双向、基于连接的字节流。可以支持带外数据传输机制。 - SOCK_DGRAM
支持数据报（无连接、不可靠、最大长度固定的消息）。 - SOCK_RAW
提供原始网络协议访问。 - SOCK_RDM
提供一个不保证排序的可靠数据报层。 - SOCK_SEQPACKET
为固定最大长度的数据报提供有序、可靠、基于双向连接的数据传输路径；使用者需要用每个输入系统调用读取整个数据包。
3、python 3.8 proto的取值，此值称为 Assigned Internet Protocol Numbers
IPPROTO_AH = 51
IPPROTO_CBT = 7
IPPROTO_DSTOPTS = 60
IPPROTO_EGP = 8
IPPROTO_ESP = 50
IPPROTO_FRAGMENT = 44
IPPROTO_GGP = 3
IPPROTO_HOPOPTS = 0
IPPROTO_ICLFXBM = 78
IPPROTO_ICMP = 1
IPPROTO_ICMPV6 = 58
IPPROTO_IDP = 22
IPPROTO_IGMP = 2
IPPROTO_IGP = 9
IPPROTO_IP = 0
IPPROTO_IPV4 = 4
IPPROTO_IPV6 = 41
IPPROTO_L2TP = 115
IPPROTO_MAX = 256
IPPROTO_ND = 77
IPPROTO_NONE = 59
IPPROTO_PGM = 113
IPPROTO_PIM = 103
IPPROTO_PUP = 12
IPPROTO_RAW = 255
IPPROTO_RDP = 27
IPPROTO_ROUTING = 43
IPPROTO_SCTP = 132
IPPROTO_ST = 5
IPPROTO_TCP = 6
IPPROTO_UDP = 17
