使用soaplib(服务器)和suds(客户端)的Pythonsoap [英] Python soap using soaplib (server) and suds (client)

问题描述

这个问题与:Python SOAP 服务器/客户端

soap 与 python 的情况，有推荐使用soaplib(http://wiki.github.com/jkp/soaplib)作为肥皂服务器和 suds(https://fedorahosted.org/suds/) 作为肥皂客户端.我的目标是在 python 中创建可以被多个客户端(java 等)使用的肥皂服务.我尝试了soaplib中的HelloWorld示例(http://trac.optio.webfactional.com/wiki/你好世界).当客户端也使用 soaplib 时，它运行良好.

然后，我尝试使用 suds 作为使用 HelloWorld 服务的客户端，但它失败了.- 为什么会这样?不同客户端使用soaplib 服务器是否存在问题?

这里是服务器的代码:

from soaplib.wsgi_soap import SimpleWSGISoapApp从soaplib.service 导入soapmethod从soaplib.serializers.primitive 导入字符串、整数、数组代码类 HelloWorldService(SimpleWSGISoapApp):@soapmethod(String,Integer,_returns=Array(String))def say_hello(self,name,times):结果 = []对于我在范围内(0，次):results.append('你好，%s'%name)返回结果如果 __name__=='__main__':从cherrypy.wsgiserver 导入CherryPyWSGIServer#fromcherrypy._cpwsgiserver 导入 CherryPyWSGIServer# 这个例子使用CherryPy2.2，CherryPy 3.0使用cherrypy.wsgiserver.CherryPyWSGIServerserver = CherryPyWSGIServer(('localhost',7789),HelloWorldService())服务器启动()

这是soaplib客户端:

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

结果:

<预><代码>>>>['你好，戴夫'，'你好，戴夫'，'你好，戴夫'，'你好，戴夫'，'你好，戴夫']

这是 suds 客户端:

from suds.client import Clienturl = 'http://localhost:7789/HelloWordService?wsdl'客户 1 = 客户(网址)client1.service.say_hello("戴夫",5)

结果:

解决方案

尝试将原语导入您的类:

class HelloWorldService(SimpleWSGISoapApp):从soaplib.serializers.primitive 导入字符串、整数、数组代码@soapmethod(String,Integer,_returns=Array(String))

This question is related to: Python SOAP server / client

In the case of soap with python, there are recommendation to use soaplib (http://wiki.github.com/jkp/soaplib) as soap server and suds (https://fedorahosted.org/suds/) as soap client. My target is to create soap services in python that can be consumed by several clients (java, etc). I tried the HelloWorld example from soaplib (http://trac.optio.webfactional.com/wiki/HelloWorld). It works well when the client is also using soaplib.

Then, I tried to use suds as client consuming the HelloWorld services and it fail. -Why this is happening? Does soaplib server has problems to consumed by different clients?

Here the code for the server:

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()

This is the soaplib client:

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)

Results:

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

This is the suds client:

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

Results:

    >>> Unhandled exception while debugging...

TypeNotFound: Type not found: '(string, HelloWorldService.HelloWorldService, )'

解决方案

try to import primitives into your class:

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