对于已部署到IIS的服务,我有以下配置。我可以使用URL向wsHttpBinding端点添加服务的服务引用,但我无法使用URL将其添加到mexHttpBinding端点(我想切换客户端以使用netTcpBinding)
我得到的错误是:
下载'http:// ServerName:98 / MyService.svc / mex'时出错。
请求失败,HTTP状态为400:错误请求。
元数据包含无法解析的引用:'http:// ServerName:98 / MyService.svc / mex'。

最奇怪的是,这个配置几乎是从我配置和部署的另一个服务中逐字复制的,并且我能够使用mexHttpBinding端点成功地向客户端添加服务引用。原始服务的配置如下:

正如您将注意到的,配置中唯一相关的差异是netTcpBinding端点和mexHttpBinding端点的地址。最初,我开始时他们都是空的,但是当我一直在尝试让它工作时,我添加了明确的地址。
此外,两个服务在IIS中配置相同,即在相关端口上启用并配置net.tcp绑定。它们也在同一服务器上运行单独的站点和单独的应用程序池(并且两个应用程序池都以相同的身份运行)。
任何帮助都将不胜感激,谢谢。

解决了它。我们为每个部署的环境都有一个Web。{Environment} .config,并且由于Web上的文件锁定(可能没有从TFS中检出),因此在构建时没有通过Web.config复制正确的配置。 ...
我应该首先检查其中一件事,但是当它一直在以前工作然后突然破裂而没有警告我从未想过检查。

在IIS中使用服务时,无法在端点配置中设置绝对URL。根URL由IIS控制,它遵循Web站点(指定端口)/ Web应用程序/虚拟目录/ SvcFile的常见结构。您只能指定.svc文件后指定的地址的相对部分。
设置完整的绝对地址和基址仅适用于自托管方案。
即使使用wsHttpBinding端点添加服务引用,您仍应该能够将其切换到netTcpBinding端点,因为应该在WSDL中描述该端点(如果删除这些绝对地址)。应在客户端的配置文件中配置两个端点。然后,您只需要将端点配置的名称传递给服务存根(WCF代理)的构造函数。
