使用 WCFTestClient 测试简单 WCF Web 服务的 WCF 错误 [英] WCF Errors using WCFTestClient to test a simple WCF Web Service

问题描述

当我尝试使用wcftestclient"测试 AutoLotWCFService 时，出现以下错误.我究竟做错了什么?任何见解都会有所帮助.这是一个简单的 Web 服务，它具有 wshttpbinding 与接口契约和服务中的实现.这是长错误消息:Web.Config 文件有 2 个端点 - 一个用于 Web 服务本身，另一个用于 metaDataExchange.它几乎都是默认的东西.如果需要，我可以包含代码 - 似乎我无法在此处附加文件.

When I try to test the AutoLotWCFService using "wcftestclient", I get the following error. What am I doing wrong? Any insight will help. This is a simple Web Service that has wshttpbinding with interface contract and the implementation in the service. Here is the long error message: The Web.Config file has 2 endpoints - one for Web Service itself and other for metaDataExchange. Its all pretty much default stuff. I can include the code if needed - it seems I cannot attach files here.

推荐答案

我最近在尝试在 IIS7 下的 Windows Vista 笔记本电脑上托管 WCF 时遇到了这个问题.

I recently had this problem whilst trying to host WCF on my Windows Vista Laptop under IIS7.

我首先收到以下错误:HTTP 错误 404.3 - 未找到"，建议的解决方法之一是确保映射了当前页面的预期处理程序."

I first recieved the following error : "HTTP Error 404.3 - Not Found" and one of the resolutions suggested was to "Ensure that the expected handler for the current page is mapped."

所以我手动为 .svc 文件添加了一个处理程序并将其定义为 DiscoveryRequestHandler，认为这可能会有所帮助.这导致了您上面描述的问题.

So I added a handler for the .svc file manually and defined it as a DiscoveryRequestHandler, thinking that this might help. This caused the problem you described above.

实际的解决方案是删除我添加的处理程序，并运行以下命令:

The actual resolution was to delete the handler I had added, and to run the following commands:

CD c:\windows\Microsoft.Net\Framework\v3.0\Windows Communication Foundation\
ServiceModelReg -i

这解决了我的问题并且服务运行良好.我希望这可能有助于阐明您的问题.我不能确定，但​​这可能是因为我在开发笔记本电脑上安装各种软件包的顺序.

This resolved my issue and the service is working fine. I hope this might help shed some light on your problem. I can't be certain but this is probably because of the order in which I've installed the various packages on my dev laptop.
