Hi Martin,
Thanks for the detailed reply. I edited, saved and opened the file again.
Still I am getting exactly the same error.
Putting bigger chunk of code and the error again:
# create socket
s = socket.socket(socket.AF_INET)
#create a SSL context with the recommended security settings for client
sockets, including automatic certificate verification:
context = ssl.create_default_context()
# Alternatively, a customized context could be created:
#context = ssl.SSLContext(ssl.PROTOCOL_SSLv23)
#context.verify_mode = ssl.CERT_REQUIRED
#context.check_hostname = True
# Load a set of default CA certificates from default locations
#context.load_default_certs()
ssl_sock = context.wrap_socket(s, server_hostname ='firehose.flightaware.com
')
print("Connecting...")
ssl_sock.connect(('firehose.flightaware.com', 1501))
print("Connection succeeded")
# send initialization command to server:
ssl_sock.write(bytes(initiation_command, 'UTF-8'))
# return a file object associated with the socket
file = ssl_sock.makefile('r')
# use "while True" for no limit in messages received
count = 10
while (count > 0):
try :
# read line from file:
print(file.readline())
# parse
parse_json(file.readline())
count = count - 1
except socket.error as e:
print('Connection fail', e)
print(traceback.format_exc())
# wait for user input to end
# input("\n Press Enter to exit...");
# close the SSLSocket, will also close the underlying socket
ssl_sock.close()
----------
Error:
except socket.error as e:
^
SyntaxError: invalid syntax
TIA.
