【问题描述】：

我有一个启用 ADFS 的 asp.net mvc2 应用程序，并在 IIS 中配置了 HTTPS 绑定（端口号：443）。该站点在 IIS 中配置为 DefaultWebSite。我有一个 WCF 服务：asp.net mvc2 项目中的 ChartsService.svc，该项目用于同一解决方案中存在的 silverlight 项目。在本地开发环境完成测试后，我已经将代码部署到更高的环境。它在所有环境中都没有任何问题。当我尝试使用 silverlight 项目时，在暂存服务器中突然出现 WCF 错误，如下所述：

System.InvalidOperationException ServiceMetadataBehavior的HttpGetEnabled属性设置为true，HttpGetUrl属性是相对地址，但是没有http基地址。要么提供一个 http 基地址，要么将 HttpGetUrl 设置为一个绝对地址。

Staging 网络服务器正在使用 IIS7.0。目前我在 web.config 中有以下配置：

<behaviors>
        <serviceBehaviors>
            <behavior name="VATScan.Web.ChartsServiceBehavior">
                <serviceMetadata httpGetEnabled="true" />
                <serviceDebug includeExceptionDetailInFaults="true" />
            </behavior>
        </serviceBehaviors>
    </behaviors>
    <services>
        <service behaviorConfiguration="DemoApp.Web.ChartsServiceBehavior" name="DemoApp.Web.ChartsService">
            <endpoint address="" binding="basicHttpBinding" bindingConfiguration="ServicesBinding" contract="DemoApp.Web.IChartsService" />
        </service>
    </services>

令我惊讶的是，它在所有更高的环境中仍然可以正常工作，除了在与上面提到的相同配置的 Staging 中。

谁能帮我解决这个问题？

我已在 web.config 的以下代码中将 httpGetEnabled 修改为 httpsGetEnabled 并解决了问题。

<behaviors>
        <serviceBehaviors>
            <behavior name="DemoApp.Web.ChartsServiceBehavior">
                <serviceMetadata httpsGetEnabled="true" />
                <serviceDebug includeExceptionDetailInFaults="true" />
            </behavior>
        </serviceBehaviors>
    </behaviors>
    <services>
        <service behaviorConfiguration="DemoApp.Web.ChartsServiceBehavior" name="DemoApp.Web.ChartsService">
            <endpoint address="" binding="basicHttpBinding" bindingConfiguration="ServicesBinding" contract="DemoApp.Web.IChartsService" />
        </service>
    </services>

【讨论】：

我想强调一下，在 httpGetEnabled 之前，正确的是 httpsGetEnabled。请注意字母's'

【解决方案2】：

上面的答案是一种解决方案，这里是另一种解决方案。

试试这个：

<serviceBehaviors>
    <behavior name="VATScan.Web.ChartsServiceBehavior">
        <serviceMetadata httpGetEnabled="true" httpGetUrl="[your service address]" />
        <serviceDebug includeExceptionDetailInFaults="true" />
    </behavior>
</serviceBehaviors>

将 [您的服务地址] 替换为“http://localhost:8080/ChartsServiceBehavior”之类的内容

成功了吗？

非常感谢您的回复 :)

我今天遇到了这个问题，但上述解决方案都不适合我。我通过执行以下操作解决了它。

检查您尝试打开的“ServiceHost”类型。例如：

..
myServiceHost = new ServiceHost(typeof(CMDataCollector.CMDataService));
myServiceHost.Open();      //this line was giving the above exception
..

“ServiceHost”的类型应该是您配置中的服务名称，如下所示。

      <service name="CMDataCollector.CMDataService">
        <endpoint address="rest" binding="webHttpBinding" contract="CMDataCollector.IRealtimeDataService" behaviorConfiguration="jsonBehavior" />
        <endpoint address="" binding="basicHttpBinding" contract="CMDataCollector.IRealtimeDataService">
          <identity>
            <dns value="localhost" />
          </identity>
        </endpoint>
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:9080/TRealtimeData/" />
          </baseAddresses>
        </host>
      </service>

“ServiceHost”的类型和配置中的服务名称应该相同。然后就可以打开“ServiceHost”并启动服务了

【解决方案4】：

Either supply an HTTP base address or set HttpsGetUrl to an absolute address.

发生此错误是因为设置在逻辑上错误。如果启用 httpGetEnabled 意味着，您允许客户端通过 HTTP 检索元数据（意味着客户端可以获取有关提供的那些方法服务的信息）。如果您不提供 HTTP 的 URL，客户端如何从 HTTP 检索元数据。因此，错误消息会提醒您提供 URL。

你有三个选择。

提供 httpGetUrl 作为上面显示的其他答案
通过 IIS 绑定地址

将 httpGetEnabled 设置为 false 或某些答案将 httpGetEnabled 修改为 httpsGetEnabled 意味着他们的 IIS 上只有 HTTPS 绑定设置
