Python中WebService客户端接口调用及身份验证的问题

from suds.client import Client
from suds.transport.http import HttpAuthenticated
import base64
import urllib2
 
# 一：无需身份验证的简单调用
url = "http://localhost:8899/?wsdl"
client = Client(url)    # 可以print client进行相关信息查看
client.service.methodName(*args)    # 方法调用
req = str(client.last_sent())    # 保存请求报文，因为返回的是一个实例，所以要转换成str
response = str(client.last_received())    # 保存返回报文，返回的也是一个实例
 
# 二：需要身份验证的调用
 
# 1.
client = Client(url=wsdl_url, username=username, passWord=password)
 
# 2.
t = HttpAuthenticated(username=username, password=password)
client = Client(url=url, transport=t)
 
# 3.
t = HttpAuthenticated(username=username, password=password)
t.handler = urllib2.HTTPBasicAuthHandler(t.pm)    # 这种我的报错了，t.pm告知我没这个对象
t.urlopener = urllib2.build_opener(t.handler)
client = Client(url=wsdl_url, transport=t)
 
# 4.
base64string = base64.encodestring('%s:%s' % (username, password)).replace('\n', '')
authenticationHeader = {
    "SOAPAction" : "ActionName",
    "Authorization" : "Basic %s" % base64string
}
client = Client(url=wsdl_url, headers=authenticationHeader)

#步骤很简单,导入相关库，定义url获取返回即可
import suds
from suds.client import Client

url='xxx'
client=Clinet(url)
result = client.service.xxx('xxx') #第一个xxx是webservice接口中你要调用的函数名，第二个xxx是你要输入的参数。如果不需要就空着。假如是复杂参数，可以使用client.factory方式来构建。
