I have been trying to control a camera through a wsdl file using SUDS. I have got the code working but I want to place error handling into the script. I have tried different exceptions but am unable to get the script working. When I enter an invalid coordinate I get an error. The code I am using is below followed by the error I am recieving.
#!/home/build/Python-2.6.4/python
import suds
from suds.client import Client

# Absolute Move Function

####################################################################
def absoluteMove():
# connects to WSDL file and stores location in variable 'client'
client = Client('http://file.wsdl')
# Create 'token' object to pass as an argument using the 'factory' namespace
token = client.factory.create('ns4:ReferenceToken')
print token
# Create 'dest' object to pass as an argument and values passed to this object
dest = client.factory.create('ns4:PTZVector')
dest.PanTilt._x=400
dest.PanTilt._y=0
dest.Zoom._x=1
print dest
# Create 'speed' object to pass as an argument and values passed to this object
speed = client.factory.create('ns4:PTZSpeed')
speed.PanTilt._x=0
speed.PanTilt._y=0
speed.Zoom._x=1
print speed
# 'AbsoluteMove' method invoked passing in the new values entered in the above objects
try:
result = client.service.AbsoluteMove(token, dest, speed)
except RuntimeError as detail:
print 'Handling run-time error:', detail
print "absoluteMove result ", result
result = absoluteMove()
The error is below:
No handlers could be found for logger "suds.client"
Traceback (most recent call last):
File "ptztest.py", line 48, in <module>
if __name__ == '__main__': result = absoluteMove()
File "ptztest.py", line 42, in absoluteMove

suds.WebFault: Server raised fault: 'Error setting requested pan'
I am not sure which exception I should be using here. Does anyone know how to catch this error. The x coordinate with the value 400 is in degree's that is why the error happens.
Thanks
Okay I have found the solution. In SUDS if you enter:
faults=False
into the client definition, this catches faults and gives the reason why the fault happened. The line should read:
client = Client('http://file.wsdl', faults=False)
The post that I have marked as the correct answer also is able to catch that a problem has happened.
Thanks all
If you handled all exceptions and errors in your code and your code is working fine but still you are getting below message with your correct output.
Msg : "No handlers could be found for logger suds.client
"
Then a simple solution is to add this line
logging.getLogger('suds.client').setLevel(logging.CRITICAL)
in yourclient.py
file just after all import statement.
