Question

我有一个已知的工作Web服务，它配置为SOAP和REST绑定。我可以使用测试工具调用它，我可以看到SOAP POST，然后SOAP响应都很好。

然而，当我尝试在Visual Studio 2010 Cassini中托管服务时，我会遇到以下行为：

1）当调用端点作为REST并使用WebChannelFactory类时，服务正常工作 2）当将端点作为SOAP调用并使用ChannelFactory类时，服务会抛出错误并得到400响应。（错误如下）。
3）当将端点作为SOAP调用并使用c＃SOAP引用时，服务正常工作。

难以理解？

我想知道是否与我使用Cassini版本的端口号这一事实有关？

就在人们开始告诉我在IIS中托管之前我真的需要在Cassini中使用它作为WCF教程的一部分

这是原始HTTP请求不起作用（当针对正在运行的IIS部署和错误的Visual Studio Web服务器调用时。

IIS工作：

POST http://api.dev.videolibraryserver.com/VLSContentService.svc/soap/ HTTP/1.1
Content-Type: text/xml; charset=utf-8
SOAPAction: "http://tempuri.org/IVLSContentService/EchoWithGet"

<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/"><s:Body><EchoWithGet xmlns="http://tempuri.org/"><message>Hello World!</message></EchoWithGet></s:Body></s:Envelope>

VISUAL STUDIO（CASSINI） - 不工作：

POST http://127.0.0.1:52587/VLSContentService.svc//soap HTTP/1.1
Content-Type: text/xml; charset=utf-8
SOAPAction: "http://tempuri.org/IVLSContentService/EchoWithGet"

虽然这个问题的答案是正确的。我的测试不是。我实际上试图在IIS和Cassini的url中传递'//'，但它对Cassini没有用。显然，IIS在处理引号时更加健壮。下面的评论谈到这个，但我想我会更新答案。

“不工作”请求的第一行在网址中有一个额外的斜杠：

POST http://127.0.0.1:52587/VLSContentService.svc//soap HTTP/1.1
                                                  ^

无法使用Visual Studio Webserver托管WCF SOAP端点
