Question

这是this question的后续行动。

根据建议by @Benjamin here，我正在尝试为我的wsdl添加服务引用（而不是Web引用）。这是有问题的wsdl的网址：

https://eu.link.fiatauto.com/tsi/DDUWsAut.php?wsdl

问题是Visual Studio生成一个空代码文件：

//------------------------------------------------------------------------------
// <auto-generated>
//     This code was generated by a tool.
//     Runtime Version:2.0.50727.3603
//
//     Changes to this file may cause incorrect behavior and will be lost if
//     the code is regenerated.
// </auto-generated>
//------------------------------------------------------------------------------

namespace test.ServiceReference1 {

}

当我尝试使用svcutil手动生成代码时，我得到以下内容：

C:\temp>svcutil https://eu.link.fiatauto.com/tsi/DDUWsAut.php?wsdl

Generating files...
Warning: No code was generated.
If you were trying to generate a client, this could be because the metadata docu
ments did not contain any valid contracts or services
or because all contracts/services were discovered to exist in /reference assembl
ies. Verify that you passed all the metadata documents to the tool.

Warning: If you would like to generate data contracts from schemas make sure to
use the /dataContractOnly option.

也许这与通过添加Web引用而不是服务引用来尝试使用服务时出现问题这一事实有关（请参阅我的other question）？

我猜wsdl有问题，但我找不到确切的内容。

由于这是其他人已经使用过的第三方服务，我认为他们不愿意改变他们的服务，所以有没有办法让.NET与该网络服务对话？

Answer 1

WSDL中存在一个错误。 dduAbortRequest消息中的最后一部分在名称末尾有一个空格。这可能只是一个错误。告诉他们，他们会解决它，他们会感谢你告诉他们。

WSDL原样无效。

<message name="dduAbortRequest">
    <part name="Ticket" type="xsd:string"/>
    <part name="ServiceId" type="xsd:string"/>
    <part name="LoginId" type="xsd:string"/>
    <part name="DocId " type="xsd:string"/> <!-- Should be "DocId" -->
</message>

免责声明：这可能不是您问题的直接答案，但我只是浪费了3个小时试图修复同样的错误信息 - 所以我也想在这里发布。

此Warning: No code was generated错误消息也可能由于C:\Windows\Temp目录上对应用程序池用户缺乏权限而触发（是的！）。

如果您收到此错误，我建议您在尝试使用“添加服务引用”对话框时切换到命令行。运行此命令，打开Fiddler作为服务URL。

 svcutil.exe https://dev.example.com/ShoppingCartWS/WCF/ShoppingCartWCF.svc?wsdl

如果您看到任何请求以500（红色）和以下响应返回：

ReadResponse() failed: The server did not return a response for this request.

然后检查C:\Windows\Temp，只需添加运行应用程序池的任何用户即可获得权限。

This is where I found the solution - many thanks!
