Python的WebService客户端：Suds

"Suds"是一个轻量级，Python的SOAP Web service 客户端。 

对于python仅作为客户端调用webservice的情况，推荐使用suds库来完成，比起zsi，soapy之类，它可以说是相当轻量级，使用非常方便。

安装suds建议使用easy_insall来做。下面是官方的一些例子：

from suds.client import Client  url = 'http://localhost:7080/webservices/WebServiceTestBean?wsdl'  client = Client(url)    #查看该service提供的方法  print client    Suds - version: 0.3.3 build: (beta) R397-20081121    Service (WebServiceTestBeanService) tns="http://test.server.enterprise.rhq.org/"     Prefixes (1):       ns0 = "http://test.server.enterprise.rhq.org/"     Ports (1):       (Soap)         Methods:           addPerson(Person person, )           echo(xs:string arg0, )           getList(xs:string str, xs:int length, )           getPercentBodyFat(xs:string name, xs:int height, xs:int weight)           getPersonByName(Name name, )           hello()           testExceptions()           testListArg(xs:string[] list, )           testVoid()           updatePerson(AnotherPerson person, name name, )     Types (23):       Person       Name       Phone       AnotherPerson

1.简单参数调用

result = client.service.getPercentBodyFat('jeff', 68, 170)  print result    result = client.service.getPercentBodyFat(name='jeff', height=68, weight=170)  print result    #词典  d = dict(name='jeff', height=68, weight=170)  result = client.service.getPercentBodyFat(**d)  print result    You have 21% body fat.

2.复杂参数

person = client.factory.create('Person')  print person

(Person)=    {      phone = []      age = NONE      name(Name) =           {              last = NONE              first = NONE          }     }

#设置变量

phone = client.factory.create('Phone')  phone.npa = 202  phone.nxx = 555  phone.number = 1212

name = client.factory.create('Name')  name.first = 'Elmer'  name.last = 'Fudd'

person.name = name  person.age = 35  person.phone = [phone]    #或者  person.phone.append(phone)

try:     person_added = client.service.addPerson(person)  except WebFault, e:    print e

在0.3.8以上版本还提供了更简单的调用方式，完美的json

person = {}  #根据对象结构构造json    phone = {      'npa':202,      'nxx':555,      'number':1212,  }    name = {      'first':'Elmer',      'last':'Fudd'  }    person['name'] = name  person['age'] = 35  person['phone'] = [phone,]    try:     person_added = client.service.addPerson(person)  except WebFault, e:    print e

3.异常处理

client = client(url, faults=False)  result = client.service.addPerson(person)  print result  ( 200, person ...)
