众所周知,在Visual Studio 2017中,您可以使用相关的WSDL添加Connected Service
并将其配置为指向您想要的SOAP服务。这样会在Reference.cs
文件中创建一组代理类,用于与相关SOAP服务进行接口。
是否有一种方法可以在 过程-以编程方式-因此我们可以确切知道 发送到目标服务?我之所以这样问,是因为我需要能够记录发送出去的实际SOAP,因此不能使用诸如Fiddler之类的单独应用程序。
我已经仔细研究了Reference.cs
文件中的代码,所有内容都被抽象得如此抽象,以至于我不知道转换实际上在哪里发生。
为了便于讨论,我使用了一个非常简单的免费SOAP服务,位于:http://www.dneonline.com/calculator.asmx
生成的Reference.cs
文件的内容显示在本文的结尾。在该代码中,您可以看到客户端类的方法AddAsync(...)
调用了base.Channel.AddAsync(intA, intB)
,该方法在CalculatorSoap
界面中定义。因此,如果Channel
是CalculatorSoap
接口,那么实际使用的具体类在哪里?这就是这么多抽象的普遍性的一个例子。
我很高兴(也很感激)听到你们任何人关于这里幕后发生的一切想法。
谢谢。

对于第3个问题,您可以使用Message Inspector扩展名。有details here on how to set it up
使用消息检查器,您可以查看,保留,处理外发请求,传入回复,传入请求和传出回复的SOAP消息。
关于内部工作原理,WCF还使用Message对象来处理SOAP信封。您可以阅读更多about that here
该消息是渠道模型的一部分,其中有一个bit of info here
