問題如下。無法通過套接字與Python連接
我有以下服務器:
import socket
class Receiver:
TCP_IP = '127.0.0.1'
TCP_PORT = 2999
BUFFER_SIZE = 20
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind((TCP_IP, TCP_PORT))
s.listen(1)
conn, addr = s.accept()
print('Connection address:', addr)
while 1:
data = conn.recv(BUFFER_SIZE)
if not data: break
print("received data:", data)
conn.send('0x55'.encode()) # echo
conn.close()
而且客戶端:
import socket import logging
class NvgClient:
_instance = None
def __init__(self):
self.s = socket.socket()
self.s.settimeout(3)
self.connect()
return
def __del__(self):
try:
self.s.close()
finally:
return
@staticmethod
def getInstance():
if(NvgClient._instance == None):
NvgClient._instance = NvgClient()
return NvgClient._instance
def connect(self):
try:
print("****** TRYING_TO_CONNECT_TO_SOCKET ********")
self.s.connect(('127.0.0.0', 2999))
except socket.error:
self.s.close()
self.s = socket.socket()
self.s.settimeout(3)
self.connect()
logging.error("Socket can`t connect! Reconnected.")
return
def send(self, data: bytearray):
try:
print("****** TRYING_TO_SEND_DATA ********")
self.s.send(data)
logging.info(str(data))
rdata = self.s.recv(1024)
if(rdata[0] == 0x55 and rdata[1:5] == data[0:4]):
logging.info('NVG OK')
return True
else:
logging.info('NVG BAD')
except socket.timeout:
self.s.close()
self.connect()
except IndexError:
logging.info('Server returns nothing. Reconnecting.')
self.s.close()
self.s = socket.socket()
self.s.settimeout(3)
self.connect()
return False
但是,當我嘗試發送一些數據,這是不可能連接到服務器: self.s.連接(('127.0.0.0',2999))。我得到socket.error。
代碼中是否有錯誤或錯誤?對於其他簡單的例子或telnet,服務器運行良好。
可否請你更新你的問題與你得到確切和完整的錯誤? –
另外,'conn.send('0x55'.encode())'對你沒有任何用處。試試'conn.send(b'\ x55')' –
