使用Visual Studio Web服务器托管WCF SOAP端点时出现问题

本文关键字：端点 SOAP 问题 WCF Studio Visual Web 服务器 使用 | 更新日期: 2023-09-27 18:00:14

我有一个已知的工作web服务，它被配置为SOAP和REST绑定。我可以用测试工具调用它，我可以看到SOAP POST的执行，然后SOAP响应都很好。

然而，当我尝试在视觉工作室2010卡西尼主持服务时，我会得到以下行为：

1） 当将端点调用为REST并使用WebChannelFactory类时，该服务可以工作
2） 当将端点调用为SOAP并使用ChannelFactory类时，服务会抛出一个错误，我得到一个400响应。（错误如下）
3） 当将端点调用为SOAP并使用c#SOAP引用时，服务就可以工作

困惑不？

我想知道这是不是和我使用卡西尼版本的端口号有关？

就在人们开始告诉我在IIS中托管之前，我真的需要在Cassini中完成这项工作，作为WCF 教程的一部分

以下是不起作用的原始HTTP请求（当针对正在工作的IIS部署和有故障的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"

Content-Length: 180
Expect: 100-continue

<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>

视觉工作室（卡西尼）-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"

******更新************

虽然这个问题的答案是正确的。我的测试没有成功。实际上，我试图在IIS和Cassini的url中传递一个"//"，但它对Cassini不起作用。显然，IIS在处理引号时更加健壮。下面的评论谈到了这一点，但我想我会更新答案。

"不工作"请求的第一行在URL中有一个额外的斜杠：

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