python使用suds调用webservice

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 ...)
