我尝试通过键入其URL来调用服务作为RESTFUL

http://localhost:50255/Service1.svc

因为我的绑定是webHttpBinding . 这给了我一个错误，说明在服务Service1实现的 Contract 列表中找不到 Contract 名称IMetadataExchange . 将ServiceMetadataBehavior直接添加到配置文件或ServiceHost以启用对此 Contract 的支持 . 当我发表评论时

<endpoint address="mex" binding ="mexHttpBinding"  contract="IMetadataExchange"/>

并尝试将我的Service1.svc文件从VS运行到浏览器中，表示此服务的元数据发布目前已禁用 .

然后我将webHttBinding更改为basicHttpBinding以获取SOAP服务并尝试通过WCF测试客户端添加它，它说无法添加服务 . 可能无法访问服务元数据 . 确保您的服务正在运行并公开元数据 .

我已经浏览过如此多的在线文章和谷歌搜索堆栈流本身，但没有什么对我有用 .
