wsdl和交互過程

打算利用curl調用wsdl描述的soap服務。

安裝wireshark win10的x64版後，發現vmware不能用了，找了網上的貼子，說要拷兩個驅動到windows\system32\drivers去。

但這兩個文件消失了。

先不管這事，打開wireshark，然後利用用python編寫的後臺和前臺，進行測試，準備抓包。

然後，設置所有的網卡，都關掉，只留下127.0.0.1也就是迴環地址。

然後開始交互，然後停卡，加過濾

ip.src == 127.0.0.1&& http

發現與自己預期的差不多。

交互分爲兩次

第一次客戶端向服務端請求wsdl描述的soap接口的形態。

第二次是客戶端發送請求。

所以，共四次

"""
This is a simple HelloWorld example to show the basics of writing
a webservice using spyne, starting a server, and creating a service
client.

Here's how to call it using suds:

#>>> from suds.client import Client
#>>> c = Client('http://localhost:8000/?wsdl')
#>>> c.service.say_hello('punk', 5)
(stringArray){
   string[] =
      "Hello, punk",
      "Hello, punk",
      "Hello, punk",
      "Hello, punk",
      "Hello, punk",
 }
#>>>
"""


from spyne import Application, rpc, ServiceBase, Iterable, Integer, Unicode

from spyne.protocol.soap import Soap11
from spyne.server.wsgi import WsgiApplication


class HelloWorldService(ServiceBase):
    @rpc(Unicode, Integer, _returns=Iterable(Unicode))
    def say_hello(ctx, name, times):
        """Docstrings for service methods appear as documentation in the wsdl.
        <b>What fun!</b>

        @param name the name to say hello to
        @param times the number of times to say hello
        @return the completed array
        """

        for i in range(times):
            yield u'Hello, %s' % name


application = Application([HelloWorldService], 'spyne.examples.hello.soap',
                          in_protocol=Soap11(validator='lxml'),
                          out_protocol=Soap11())

wsgi_application = WsgiApplication(application)


if __name__ == '__main__':
    import logging

    from wsgiref.simple_server import make_server

    logging.basicConfig(level=logging.DEBUG)
    logging.getLogger('spyne.protocol.xml').setLevel(logging.DEBUG)

    logging.info("listening to http://127.0.0.1:8000")
    logging.info("wsdl is at: http://localhost:8000/?wsdl")

    server = make_server('127.0.0.1', 8000, wsgi_application)
    server.serve_forever()

 

client

import suds

from suds.client import Client

wsdl_url = "http://localhost:8000/?wsdl"


def say_hello_test(url, name, times):
    client = Client(url)

    result = client.service.say_hello(name, times)
    print(result)
    #req = client.last_sent()
    #response = client.last_received()
    #print(req.str())
    #print(response.str())


if __name__ == '__main__':
    say_hello_test(wsdl_url, 'test', 3)

 

注意：後面的用的suds-jurko

因爲suds直接pip裝不上，需要手工裝，但這個能直接裝上。
