soaplib实现Webservice

1、安装setuptools，执行如下命令

 sudo apt-get install python-setuptools

安装该软件是为了下面使用easy_install命令安装soaplib

2、安装soaplib

soaplib依赖于Twisted、lxml，而lxml依赖于libxml和libxslt

2.1安装libxml

下载libxml2-2.7.2.tar.gz，解压cd到解压目录，执行如下命令：

./configure

make

make install

2.2安装libxslt，在线安装，执行如下命令：

sudo apt-get install libxslt-dev

2.3 安装pytz，下载pytz-2012h.tar.bz，解压，进入解压目录，执行如下命令：

sudo python setup install

2.4 安装soaplib，执行如下命令：

easy_install soaplib

2.5 客户端需要安装suds，从https://pypi.python.org/pypi/suds下载suds.tar.gz，解压，进入解压路径，执行如下命令

sudo python setup install

3、编写服务端代码，如下：

import soaplib
from soaplib.core.service import rpc, DefinitionBase
from soaplib.core.model.primitive import String, Integer
from soaplib.core.server import wsgi
from soaplib.core.model.clazz import Array
from soaplib.core.service import soap

class HelloWorldService(DefinitionBase):
    @soap(String,Integer,_returns=Array(String))
    def say_hello(self,name,times):
        results = []
        for i in range(0,times):
            results.append('Hello, %s'%name)
        return results

if __name__=='__main__':
    try:
        from wsgiref.simple_server import make_server
        soap_application = soaplib.core.Application([HelloWorldService], 'tns')
        wsgi_application = wsgi.Application(soap_application)
        server = make_server('localhost', 7789, wsgi_application)
        server.serve_forever()
    except ImportError:
        print "Error: example server code requires Python >= 2.5"

启动以上程序， 在浏览器重访问 http://127.0.0.1:7789/SOAP/?wsdl，如 果正常的话，则能看到该服务的描述信息，包括各个方法的输入参数、返回值，以及实体类的信息。

4、编写客户端程序：

from suds.client import Client
hello_client = Client('http://localhost:7789/?wsdl')
result = hello_client.service.say_hello("Dave", 5)
print result

运行结果如下

string[] = 
      "Hello, Dave",
      "Hello, Dave",
      "Hello, Dave",
      "Hello, Dave",
      "Hello, Dave",
