wsdl和交互过程

曾经终败给现在 2023-08-17 15:33 101阅读 0赞

打算利用curl调用wsdl描述的soap服务。

安装wireshark win10的x64版后，发现vmware不能用了，找了网上的贴子，说要拷两个驱动到windows\\system32\\drivers去。

但这两个文件消失了。

先不管这事，打开wireshark，然后利用用python编写的后台和前台，进行测试，准备抓包。

然后，设置所有的网卡，都关掉，只留下127.0.0.1也就是回环地址。

然后开始交互，然后停卡，加过滤

ip.src == 127.0.0.1&& http

发现与自己预期的差不多。

交互分为两次

第一次客户端向服务端请求wsdl描述的soap接口的形态。

第二次是客户端发送请求。

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.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()

        say_hello_test(wsdl_url, 'test', 3)

注意：后面的用的suds-jurko

因为suds直接pip装不上，需要手工装，但这个能直接装上。
