sbl*_*eon 6 .net c# coldfusion soap web-services
I've been trying for a couple of days now to get a .NET client working fully with a Web Server provided by my Coldfusion-based web app. I'm not a .NET developer, per se, but I happen to have a copy of VS 2003, which seems like it should do the trick.
I can use a simple multiplier() method in my web service that takes two numbers and returns a number, so simple types are working fine. It's the complex types that are killing me. I'm basically trying to return an associative array from a method called get_struct(). I get an object of type Map back, but the property (called item), which is supposed to be an array with two elements (of type mapItem) always has an "undefined value".
Here's the WSDL that is generated by ColdFusion:

Console.WriteLine("Instantiating WS");
remote_io_test.remote_io_testService testWS = new remote_io_test.remote_io_testService();
Console.WriteLine("Calling multiplier(3,15)");
Console.WriteLine(testWS.multiplier(3,15));
Console.WriteLine("Calling get_struct()");
remote_io_test.Map theStruct = testWS.get_struct();
Console.Write("result: ");
Console.WriteLine(theStruct);
Console.Write("result.item: ");
Console.WriteLine(theStruct.item);
Console.WriteLine("Press Enter to exit...");
Console.ReadLine();
}
}
}
No matter what I try, theStruct.item is always "undefined value" according to the debugger. The printed output looks like:
Instantiating WS
Calling multiplier(3,15)
45
Calling get_struct()
result: pfapi_test.remote_io_test.Map
result.item:
Press Enter to exit...
I've tried using ColdFusion 8, and there's no difference. I've tried returning a real custom database with two properties instead of my ad-hoc associative array, and that works fine, but rewriting my API to avoid associative arrays isn't really an option at this time. The API works fine with ColdFusion, PHP/NuSOAP, and Ruby on Rails, so it seems like it should be possible to get it working with .NET as well.
我希望有人可以提供一些见解.我怀疑这里存在某种命名空间问题,但我不太了解SOAP和XML,无法弄清楚它是什么.我也疯狂搜索在线解决方案,但我找不到一个人解决了这个问题,这是非常令人沮丧的!

更新:我从另一端的.NET开发人员那里听到,并且他尝试了以下所有内容但无济于事:
他确实向我发送了"服务参考设置"对话框的"数据类型"部分的屏幕截图.是否可能更改Collection类型和Dictionary集合类型的设置可能会解决此问题？
更新2:这是remote_io_test.cfc的ColdFusion代码

感谢您的阅读,并提前感谢您的回复!

答案是：不要在您的 Web 服务中使用 Coldfusion 结构。
与我们之前的其他人一样，我们放弃并重写了 API，以便不在请求或响应中使用任何关联数组。我们现在使用从 CFC 自动创建的标量、数组和复杂类型。这一次，我们使用 PHP、Ruby、Coldfusion、Java 和 .NET 测试了我们的概念验证，以确保它实际上是可互操作的。
现在，静态类型语言无法以任何合理的方式处理完全任意的远程数据类型，这是很有意义的。
