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：

Python代码

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

Python代码

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

Java代码

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

Java代码

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

#设置变量

Java代码

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

Python代码

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

Python代码

person.name = name
person.age = 35
person.phone = [phone]

#或者
person.phone.append(phone)

Java代码

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


Python代码

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

Python代码

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

cache等高级话题，有需要可以查看，都比较详细。
