使用 SUDS 在 Python 中处理错误 [英] Error Handling in Python with SUDS
问题描述
我一直在尝试使用 SUDS 通过 wsdl 文件控制相机.我已经使代码正常工作,但我想将错误处理放入脚本中.我尝试了不同的例外,但无法使脚本正常工作.当我输入无效坐标时,我收到错误消息.下面是我使用的代码,后面是我收到的错误.
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

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()
错误如下:
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
result = client.service.AbsoluteMove(token, dest, speed)

File "build/bdist.linux-i686/egg/suds/bindings/binding.py", line 235, in get_fault
suds.WebFault: Server raised fault: 'Error setting requested pan'
我不确定我应该在这里使用哪个例外.有谁知道如何捕捉这个错误.值为 400 的 x 坐标以度为单位,这就是发生错误的原因.
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.
谢谢
好的,我找到了解决方案.在 SUDS 中,如果您输入:
Okay I have found the solution. In SUDS if you enter:
faults=False
进入客户端定义,这会捕获故障并给出故障发生的原因.该行应为:
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)
我标记为正确答案的帖子也能够发现问题发生了.
The post that I have marked as the correct answer also is able to catch that a problem has happened.
谢谢大家
推荐答案
如果你想捕捉那个异常,你应该把
If you want to catch that exception you should put
try:
result = client.service.AbsoluteMove(token, dest, speed)
except suds.WebFault as detail:
