Exemples de clients de services Web Python

Exemples illustrant une intégration avec un client de services Web Python.

Besoins

Les exemples suivants nécessitent l’installation des modules Python suivants :

• FPCONST http://pypi.python.org/pypi/fpconst/0.7.2
• http://pyxml.sourceforge.net/topics/ PyXML
• http://pywebsvcs.sourceforge.net/ SOAPpy

insérer

Voici un exemple d’insertion d’incident.

#!/usr/bin/python
 
 from SOAPpy  import SOAPProxy
 import sys
 
 def createincident (params_dict ):
 
         # instance to send to
        instance = 'demo'
 
         # username/password
        username = 'itil'
        password = 'itil'
 
 
         # proxy - NOTE: ALWAYS use https://INSTANCE.service-now.com, not https://www.service-now.com/INSTANCE for web services URL from now on!
        proxy  = 'https://%s:%s@%s.service-now.com/incident.do?SOAP' %  (username , password , instance )
        namespace  = 'http://www.service-now.com/'
        server  = SOAPProxy (proxy , namespace )
 
         # uncomment these for LOTS of debugging output #server.config.dumpHeadersIn = 1 #server.config.dumpHeadersOut = 1 #server.config.dumpSOAPOut = 1 #server.config.dumpSOAPIn = 1
 
        response  = server. insert (impact = int (params_dict [ 'impact' ] ) , urgency = int (params_dict [ 'urgency' ] ) , priority = int (params_dict [ 'priority' ] ) , category =params_dict [ 'category' ] , location =params_dict [ 'location' ] , caller_id =params_dict [ 'user' ] , assignment_group =params_dict [ 'assignment_group' ] , assigned_to =params_dict [ 'assigned_to' ] , short_description =params_dict [ 'short_description' ] , comments =params_dict [ 'comments' ] )
 
         return response
 
values  = { 'impact':  '1' , 'urgency':  '1' , 'priority':  '1' , 'category':  'High' , 'location':  'San Diego' , 'user':  '[e-mail]' , 'assignment_group':  'Technical Support' , 'assigned_to':  'David Loo' , 'short_description':  'An incident created using python, SOAPpy, and web services.' , 'comments':  'This a test making an incident with python.\n Isn \' t life wonderful?' }
 
new_incident_sysid =createincident (values )
 
 print "Returned sysid: "+ repr (new_incident_sysid )

getKeys (en anglais)

Voici un exemple d’exécution de getKeys sur l’instance de démonstration à l’aide de l’authentification de base.

#!/bin/env python
 
 # use the SOAPpy module from SOAPpy  import SOAPProxy
 
username , password , instance  = 'admin' , 'admin' , 'demo'
proxy , namespace  = 'https://username:[e-mail]/'+instance+ '/incident.do?SOAP' , 'http://www.service-now.com/'
 
server  = SOAPProxy (proxy ,namespace )
response  = server. getKeys (category  = 'Network' )
 
 print response. sys_id. split ( ',' )

getRecords

Dans cet exemple, nous obtenons un incident, en interrogeant la catégorie == « Réseau » (avec authentification de base).

#!/bin/env python
 
 # use the SOAPpy module from SOAPpy  import SOAPProxy
 
username , password , instance  = 'admin' , 'admin' , 'demo'
proxy , namespace  = 'https://username:[e-mail]/'+instance+ '/incident.do?SOAP' , 'http://www.service-now.com/'
 
server  = SOAPProxy (proxy ,namespace )
response  = server. getRecords (category  = 'Network' )
 
 for record  in response:
	 for item  in record:
		 print item

get

Dans cet exemple, nous obtenons un enregistrement d’incident par sys_id (avec authentification de base).

#!/bin/env python
 
 # use the SOAPpy module from SOAPpy  import SOAPProxy
 
username , password , instance  = 'admin' , 'admin' , 'demo'
proxy , namespace  = 'https://username:[e-mail]/'+instance+ '/incident.do?SOAP' , 'http://www.service-now.com/'
 
server  = SOAPProxy (proxy ,namespace )
response  = server. get (sys_id  = '9c573169c611228700193229fff72400' )
 
 for each  in response:
	 print each

Avancé

Il s’agit d’un exemple de script Python avancé qui lit un fichier journal pour un mot clé SPI non valide et crée un enregistrement de file d’attente ECC où la charge utile est définie sur une alerte au format XML.

#!/bin/env python
 
 # [e-mail]			2008.07.03		initial creation

 # state file
statefile = '/tmp/syslog_ecc.state-test'
 
 # ECC queue values
soapagent = 'SOAPpy'

	errorpayload = 'This message was generated due to an error condition encountered in a script.  The name of the script is '+ os. path. basename ( sys. argv [ 0 ] )+ ' on server '+ socket. gethostname ( )+ '.'
 
	proxy  = 'https://'+username+ ':'+password+ '@'+instance+ '.service-now.com/ecc_queue.do?SOAP'

	server. config. dumpSOAPOut = 1 
	server. config. dumpSOAPIn = 1 
        response  = server. insert (agent =soapagent , topic =errortopic , name =errorname , source = sys. argv [ 0 ] , payload =errorpayload )
 
	 sys. exit ( 1 )
 
 if lastbyte  != 0:
	 try:
		log. seek (lastbyte ) except IOError:
		 pass
 
loglines =log. readlines ( )
 
lastbyte =log. tell ( )
 
log. close ( )
 
state = open (statefile , 'w' ) pickle. dump (lastbyte , state )
state. close ( )
 
 # regex out the line
matchedlines = [ ] for line  in loglines:
	 if re. search (matchstring , line ) != None:

 if len (matchedlines ) == 0:
	 sys. exit ( 0 )
 
proxy  = 'https://'+username+ ':'+password+ '@'+instance+ '.service-now.com/ecc_queue.do?SOAP'
namespace  = 'http://www.service-now.com/'
 
server  = SOAPProxy (proxy , namespace ) #server.config.dumpSOAPOut = 1 #server.config.dumpSOAPIn = 1
 
entriestosend = { } for line  in matchedlines:
	device =line. split ( ) [ 3 ]
	sourceip =line. split ( ) [- 1 ]
	entriestosend [sourceip ] = [device , line ]
 
 for key ,value  in entriestosend. iteritems ( ):
	 #impl=getDOMImplementation() #newdoc = impl.createDocument(None, "log_line", None) #top_element = newdoc.documentElement #text = newdoc.createTextNode(value[1]) #top_element.appendChild(text)
 
	response  = server. insert (agent =soapagent , topic =ecctopic+value [ 0 ] , name =eccname+key , source =eccsource , payload =value [ 1 ] )
