如何让 WCF 与此 Web 服务通信? [英] How can I make WCF talk to this web service?
问题描述
这是这个问题的后续.
按照@Benjamin 此处的建议，我现在正在尝试为我的 wsdl 添加服务引用(而不是 Web 引用).这是相关 wsdl 的网址:
<块引用>https://eu.link.fiatauto.com/tsi/DDUWsAut.php?wsdl
问题在于 Visual Studio 生成了一个空的代码文件:
//----------------------------------------------------------------//<自动生成>//此代码是由工具生成的.//运行时版本:2.0.50727.3603////对此文件的更改可能会导致不正确的行为，并且在以下情况下会丢失//重新生成代码.//</自动生成>//------------------------------------------------------------------------------命名空间 test.ServiceReference1 {}当我尝试使用 svcutil 手动生成代码时，我得到以下信息:

我猜那个 wsdl 有问题，但我找不到确切的原因.
由于这是其他人已经在使用的第三方服务，我认为他们不会愿意改变他们的服务，那么是否有任何解决方法让 .NET 与该网络服务对话?
WSDL 中存在一个错误.dduAbortRequest 消息的最后一部分在名称末尾有一个空格.那可能只是一个错误.告诉他们，他们会修复它，他们会感谢你告诉他们.
WSDL 完全无效.
<part name="Ticket" type="xsd:string"/><part name="ServiceId" type="xsd:string"/><part name="LoginId" type="xsd:string"/><part name="DocId" type="xsd:string"/><!-- 应该是DocId"--></消息> This is a follow up of this question.
As suggested by @Benjamin here, I am trying to add a service reference for my wsdl now (in stead of a web reference). Here is the url to the wsdl in question:
The problem is that Visual Studio generates an empty codefile:
//------------------------------------------------------------------------------
// <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 {
}
When I try to manually generate the code using svcutil, I get the following:
C:\temp>svcutil https://eu.link.fiatauto.com/tsi/DDUWsAut.php?wsdl Microsoft (R) Service Model Metadata Tool [Microsoft (R) Windows (R) Communication Foundation, Version 3.0.4506.2152] Copyright (c) Microsoft Corporation.

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.
Maybe this has also something to do with the fact that there are problems when trying to use the service by adding a web reference in stead of a service reference (see my other question)?
I guess there's something wrong with that wsdl, but I can't find what exactly.
As this is a third party service which is already used by others, I don't think they will be willing to change their service, so are there any workarounds to let .NET talk to that web service?
There's a bug in the WSDL. The final part in the dduAbortRequest message has a space at the end of the name. That's probably just a bug. Tell them about it, and they'll fix it, and they'll thank you for telling them.
The WSDL is just plain invalid as-is.
<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>
