aliyun-mns/mns/mns_http.py

Lines 33 to 53 in b375d76

def connect(self):
msg = "getaddrinfo returns an empty list"
for res in socket.getaddrinfo(self.host, self.port, 0,
socket.SOCK_STREAM):
af, socktype, proto, canonname, sa = res
try:
self.sock = socket.socket(af, socktype, proto)
self.sock.settimeout(self.connection_timeout)
if self.debuglevel > 0:
print("connect: (%s, %s)" % (self.host, self.port))
self.sock.connect(sa)
except socket.error as msg:
if self.debuglevel > 0:
print('connect fail:', (self.host, self.port))
if self.sock:
self.sock.close()
self.sock = None
continue
break
if not self.sock:
raise socket.error( msg )

示例如下

def f():
    msg = 'abc'
    for i in range(10):
        try:
            raise Exception('hi')
        except Exception as msg:
            pass
    print(msg)

f()
