eBay C＃SDK不适用于Mono
我下载了eBay SDK，用于我们正在开发的内部应用程序。 我们正在开发Mono。 当我在.NET上运行eBay Hello World示例时，它显示以下输出：
+++++++++++++++++++++++++++++++++++++++ + Welcome to eBay SDK for .Net Sample + + - HelloWorld + +++++++++++++++++++++++++++++++++++++++ Begin to call eBay API, please wait ... End to call eBay API, show call result: eBay official Time: 11/27/2013 3:02:19 PM 当我使用Mono运行它时，我得到以下内容：
Unhandled Exception: eBay.Service.Core.Sdk.ApiException: Exception has been thrown by the target of an invocation. ---> System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.InvalidOperationException: WebServiceBindingAttribute is required on proxy class 'eBay.Service.Core.Sdk.eBayAPIInterfaceService2'. at System.Web.Services.Protocols.SoapTypeStubInfo..ctor (System.Web.Services.Protocols.LogicalTypeInfo logicalTypeInfo) [0x00000] at (wrapper managed-to-native) System.Reflection.MonoCMethod:InternalInvoke (object,object[],System.Exception&) etc...etc...etc...
我找到了一个解决方法，并将其发布在下面的答案中。
我搜索了Xamarin的Bugzilla并没有发现任何内容，但我在Novell的旧Mono Bugzilla中发现了相关的错误： https ：//bugzilla.novell.com/show_bug.cgi ？ id = 693367
所以我挖掘了eBay SDK源代码，发现这确实是个问题。 eBay.Service.Core.Sdk.eBayAPIInterfaceService2inheritance自eBay.Service.Core.Sdk.eBayAPIInterfaceService ，后者使用System.Web.Services.WebServiceBindingAttribute修饰。
所以我改变了eBay.Service.Core.Sdk.eBayAPIInterfaceService2 ，添加了[System.Web.Services.WebServiceBindingAttribute(Name = "eBayAPISoapBinding", Namespace = "urn:ebay:apis:eBLBaseComponents")] ，现在它看起来如下所示：
using System; using System.Net; using eBay.Service.Core.Soap; namespace eBay.Service.Core.Sdk { /// /// Enhanced eBayAPIInterfaceService with GZIP compression support. /// [System.Web.Services.WebServiceBindingAttribute(Name = "eBayAPISoapBinding", Namespace = "urn:ebay:apis:eBLBaseComponents")] internal class eBayAPIInterfaceService2 : eBayAPIInterfaceService { ... } }
我按照eBay SDK中的说明从源代码构建，问题解决了。
脚注 ：顺便说一句，如果这是您第一次使用Mono连接到HTTPS Web服务，则可能会立即遇到另一个exception。 那个看起来像这样：
Unhandled Exception: System.Net.WebException: Error getting response stream (Write: The authentication or decryption has failed.): SendFailure ---> System.IO.IOException: The authentication or decryption has failed. ---> Mono.Security.Protocol.Tls.TlsException: Invalid certificate received from server.
