我也只是想明白这一点。不过，我已经完成了这件事的核心，所以这应该可以为其他需要它的人加快速度！我假设其他 Sage 子系统以相同的方式工作（但我还不知道），所以我试图解释这种可能性。
首先，你需要我写的这个模块，叫做 pySage.py。它定义了一个用于运行您需要子类化以供您自定义使用的进程的类。
#----------------------------
#
# pySage.py
#
# Author: BuvinJ
# Created: December, 2015
#
# This module defines the SageProcess class.
# This class handles connecting and disconnecting
# to Sage web services, and provides an object
# through which the web services can be accessed.
#
#----------------------------
# Download SOAPpy from: https://pypi.python.org/pypi/SOAPpy
from SOAPpy import WSDL, Types as soapTypes
from enum import Enum
SageSubsystem = Enum( 'SageSubsystem', 'CRM' )
# Define your sub system connection parameters here.
CRM_WSDL_FILE_URL = "http://CRMservername/CRMinstallname/eWare.dll/webservice/webservice.wsdl"
CRM_USER = "admin"
CRM_PASSWORD = ""
CRM_NAMESPACE = "http://tempuri.org/type"
#----------------------------
# SageProcess Class
# To use this class:
#
# 1) Create a SageProcess subclass and define the method
# body().
# 2) Instanitate an instance of the subclass, passing a
# SageSubsystem enumeration, e.g. SageSubsystem.CRM.
# 3) Invoke the run() method of the process instance.
# This will in turn invoke body() to execute your
# custom actions.
#
# To access the sage web services, use the "sage" member of
# a SageProcess instance. For help using Sage web service
# objects see:
# https://community.sagecrm.com/developerhelp/default.htm
#
# You may also invoke the sageHelp() method of a SageProcess
# instance to view the top level web service object members.
# Or, recordHelp( sageRecord ) to view the members of the
# various record objects returned by the web services.
#
#----------------------------
class SageProcess():
# Construction & service connection methods
#----------------------------
def __init__( self, subsystem, verbose=False ):
"""
@param subsystem: The Sage subsystem on which to run the process. Ex. SageSubsystem.CRM
@param verbose: If True, details of the SOAP exchange are displayed.
"""
self.subsystem = subsystem
self.verbose = verbose
if self.subsystem == SageSubsystem.CRM :
self.wsdl = CRM_WSDL_FILE_URL
self.namespace = CRM_NAMESPACE
self.username = CRM_USER

然后，为这个类添加一个客户端。这是我创建的一个名为 fetch_company_data_example.py 的示例：

#
# fetch_company_data_example.py
#
#----------------------------
from pySage import SageProcess, SageSubsystem
def main() :
# Get process parameters from the command line
import sys
try :
companyId = sys.argv[1]
except :
abort( "Usage: " + sys.argv[0] + " companyId [-v] [--verbose]" )
verbose = False
try :
if ( sys.argv[2] == "-v" or
sys.argv[2] == "--verbose" ) :
verbose = True
except : pass
# Create & run the custom Sage process
process = FetchCompanyDataProcess( companyId, verbose )
process.run()
class FetchCompanyDataProcess( SageProcess ):
def __init__( self, companyId, verbose ):
SageProcess.__init__( self, SageSubsystem.CRM, verbose )
self.companyId = companyId
def body( self ):
# Fetch the company record (exiting if no data is returned)
companyRecord = self.getCompanyRecord()
if companyRecord is None: self.quit( "\nNo records found.\n" )
# Uncomment for development help...
#if self.verbose : self.recordHelp( companyRecord, "Company" )
#if self.verbose : self.recordHelp( companyRecord.address.records, "Address" )
# Print some of the company info
print ""
print "Company Id: " + self.companyId
print "Name: " + companyRecord.name
print "Location: " + self.getCompanyLocation( companyRecord )
print ""
def getCompanyRecord( self ) :
try :
queryentity = self.sage.queryentity( self.companyId, "company" )
except Exception as e:
self.abortOnException( "Get Company Record failure.", e )
try : return queryentity.records
except : return None
def getCompanyLocation( self, companyRecord ) :
try :
return (companyRecord.address.records.city + ", " +
companyRecord.address.records.state)
except : return ""
# Entry point
