使用soaplib（服务器）和suds（客户端）的Python SOAP

Question

这个问题和以下内容有关：Python SOAP 服务器/客户端

在使用 Python 进行 SOAP 的情况下，推荐使用 soaplib (http://wiki.github.com/jkp/soaplib) 作为 SOAP 服务器，使用 suds (https://fedorahosted.org/suds/) 作为 SOAP 客户端。我的目标是创建可以被多个客户端（比如 Java 等）使用的 SOAP 服务。我尝试了 soaplib 的 HelloWorld 示例 (http://trac.optio.webfactional.com/wiki/HelloWorld)。当客户端也使用 soaplib 时，它运行得很好。

然后，我尝试使用 suds 作为客户端来调用 HelloWorld 服务，但失败了。- 为什么会这样？soaplib 服务器是否存在被不同客户端使用的问题？

这是服务器的代码：

from soaplib.wsgi_soap import SimpleWSGISoapApp
from soaplib.service import soapmethod
from soaplib.serializers.primitive import String, Integer, Arraycode
class HelloWorldService(SimpleWSGISoapApp):
@soapmethod(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__':
from cherrypy.wsgiserver import CherryPyWSGIServer
#from cherrypy._cpwsgiserver import CherryPyWSGIServer
# this example uses CherryPy2.2, use cherrypy.wsgiserver.CherryPyWSGIServer for CherryPy 3.0
server = CherryPyWSGIServer(('localhost',7789),HelloWorldService())
server.start()

这是 soaplib 客户端：

from soaplib.client import make_service_client
from SoapServerTest_1 import HelloWorldService
client = make_service_client('http://localhost:7789/',HelloWorldService())
print client.say_hello("Dave",5)

结果：

>>> ['Hello, Dave', 'Hello, Dave', 'Hello, Dave', 'Hello, Dave', 'Hello, Dave']

这是 suds 客户端：

from suds.client import Client
url = 'http://localhost:7789/HelloWordService?wsdl'
client1 = Client(url)
client1.service.say_hello("Dave",5)

结果：

这个问题已经修复了，如果你从主干获取最新的代码，具体细节可以查看这个链接：https://github.com/soaplib/soaplib/pull/12

Answer 2

试着把基本数据类型导入到你的类里：

class HelloWorldService(SimpleWSGISoapApp):
    from soaplib.serializers.primitive import String, Integer, Arraycode
    @soapmethod(String,Integer,_returns=Array(String))
