eBay的C＃SDK不单声道工作 [英] eBay C# SDK doesn't work on Mono

问题描述

我下载了eBay SDK开发用于我们正在开发一个内部应用程序。美中不足的是，我们正在开发的单声道。当我运行在.NET上易趣的Hello World样本，它会显示以下输出：

I downloaded the eBay SDK for use in an internal application we are developing. The catch is we are developing on Mono. When I run the eBay Hello World sample on .NET, it displays the following output:

+++++++++++++++++++++++++++++++++++++++
+ 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，我得到了以下内容：

When I run it with Mono, I get the following:

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...

我找到了一个解决办法，将它张贴在下面的答案。

I found a workaround and will post it in an answer below.

推荐答案

我搜索Xamarin的Bugzilla的一无所获，但我发现张贴在Novell的旧黑白的Bugzilla此相关的bug： HTTPS：//bugzilla.novell。 COM / show_bug.cgi？ID = 693367

I searched Xamarin's Bugzilla and found nothing, but I found this relevant bug posted in Novell's old Mono Bugzilla: https://bugzilla.novell.com/show_bug.cgi?id=693367

于是我通过eBay的SDK源挖出，发现这确实是问题。 eBay.Service.Core.Sdk.eBayAPIInterfaceService2 从 eBay.Service.Core.Sdk.eBayAPIInterfaceService 继承，这是装饰以 System.Web.Services.WebServiceBindingAttribute 。

So I dug through the eBay SDK source and found that this was indeed the issue. eBay.Service.Core.Sdk.eBayAPIInterfaceService2 inherits from eBay.Service.Core.Sdk.eBayAPIInterfaceService, which is decorated with a System.Web.Services.WebServiceBindingAttribute.

于是我改变了 eBay.Service .Core.Sdk.eBayAPIInterfaceService2 ，加入 [System.Web.Services.WebServiceBindingAttribute（NAME =eBayAPISoapBinding，命名空间=瓮：易趣：蜜蜂：eBLBaseComponents）] ，以便它现在看起来如下：

So I changed eBay.Service.Core.Sdk.eBayAPIInterfaceService2, adding [System.Web.Services.WebServiceBindingAttribute(Name = "eBayAPISoapBinding", Namespace = "urn:ebay:apis:eBLBaseComponents")] so that it now looks like the following:

using System;
using System.Net;
using eBay.Service.Core.Soap;

namespace eBay.Service.Core.Sdk {
    /// <summary>
    /// Enhanced eBayAPIInterfaceService with GZIP compression support.
    /// </summary>
    [System.Web.Services.WebServiceBindingAttribute(Name = "eBayAPISoapBinding", Namespace = "urn:ebay:apis:eBLBaseComponents")]
    internal class eBayAPIInterfaceService2 : eBayAPIInterfaceService {
        ...
    }
}

我也跟着在eBay SDK开发的指示从建设。来源和问题解决了。

I followed the instructions in the eBay SDK for building from the sources and the problem was solved.

脚注：顺便说一句，如果这是你第一次使用单声道连接到HTTPS Web服务，你可能会立即运行到另一个例外。这人会是这样的：

Footnote: Incidentally, if this is your first time using Mono to connect to an HTTPS web service, you will likely immediately run into another exception. That one will look like this:

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.
