我们从Python开源项目中，提取了以下33个代码示例，用于说明如何使用socket.sock()。
def connect(self): "Connects to the Redis server if not already connected" if self._sock: return try: sock = self._connect() except socket.error: e = sys.exc_info()[1] raise ConnectionError(self._error_message(e)) self._sock = sock try: self.on_connect() except RedisError: # clean up after any error in on_connect self.disconnect() raise # run any user callbacks. right now the only internal callback # is for pubsub channel/pattern resubscription for callback in self._connect_callbacks: callback(self)
def connect(self): "Connects to the Redis server if not already connected" if self._sock: return try: sock = self._connect() except socket.timeout: raise TimeoutError("Timeout connecting to server") except socket.error: e = sys.exc_info()[1] raise ConnectionError(self._error_message(e)) self._sock = sock try: self.on_connect() except RedisError: # clean up after any error in on_connect self.disconnect() raise # run any user callbacks. right now the only internal callback # is for pubsub channel/pattern resubscription for callback in self._connect_callbacks: callback(self)
def _connect(self): "Create a TCP socket connection" # we want to mimic what socket.create_connection does to support # ipv4/ipv6, but we want to set options prior to calling # socket.connect() err = None for res in socket.getaddrinfo(self.host, self.port, 0, socket.SOCK_STREAM): family, socktype, proto, canonname, socket_address = res sock = None try: sock = socket.socket(family, socktype, proto) # TCP_NODELAY sock.setsockopt(socket.IPPROTO_TCP, socket.TCP_NODELAY, 1) # TCP_KEEPALIVE if self.socket_keepalive: sock.setsockopt(socket.SOL_SOCKET, socket.SO_KEEPALIVE, 1) for k, v in iteritems(self.socket_keepalive_options): sock.setsockopt(socket.SOL_TCP, k, v) # set the socket_connect_timeout before we connect sock.settimeout(self.socket_connect_timeout) # connect sock.connect(socket_address) # set the socket_timeout now that we're connected sock.settimeout(self.socket_timeout) return sock except socket.error as _: err = _ if sock is not None: sock.close() if err is not None: raise err raise socket.error("socket.getaddrinfo returned an empty list")
def can_read(self, timeout=0): "Poll the socket to see if there's data that can be read." sock = self._sock if not sock: self.connect() sock = self._sock return self._parser.can_read() or \ bool(select([sock], [], [], timeout)[0])
def _connect(self): "Wrap the socket with SSL support" sock = super(SSLConnection, self)._connect() sock = ssl.wrap_socket(sock, cert_reqs=self.cert_reqs, keyfile=self.keyfile, certfile=self.certfile, ca_certs=self.ca_certs) return sock
