问题描述
||
我有一个已知的工作Web服务，该服务被配置为SOAP和REST绑定。我可以使用测试工具来调用它，并且可以看到SOAP POST即将进行，然后SOAP响应一切正常。
但是，当我尝试在Visual Studio 2010 Cassini中托管该服务时，会出现以下现象：
1）当将端点作为REST调用并使用WebChannelFactory类时，该服务有效。
2）当将端点作为SOAP调用并使用ChannelFactory类时，服务将引发错误，并且得到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，该服务有效。
困惑不？
我想知道我是否为Cassini版本使用了端口号吗？
在人们开始告诉我要在IIS中托管之前，我真的需要在Cassini中使它工作，这是WCF教程的一部分
这是原始HTTP请求，该请求不起作用（针对正在运行的IIS部署和故障的Visual Studio Web服务器调用时）。
IIS工作：

解决方法
您的\“不工作\”请求的第一行在URL中加了一个斜杠：
POST http://127.0.0.1:52587/VLSContentService.svc//soap HTTP/1.1
