Question

我有一个WCF应用程序作为Azure中的webrole托管，具有以下配置。在尝试访问浏览器中的三个服务wsdl中的任何一个或尝试设置代理时，我收到400 Bad Request。

    </configuration>

我很确定我的配置不对，但我需要一些不正确的指导。

接口定义为：

[ServiceContract(Name = "Service1", Namespace = "http://example.com")]
public interface IService1
{
    [WebGet]
    [OperationContract]
    Result Create();
}

您使用的是错误的绑定，请尝试使用webHttpBinding而不是basicHttpBinding。您的合同设置为WebGet，这是WCF对基于REST的服务的承担。 BasicHttpBinding仅适用于基于soap的绑定（因此“错误请求”异常）。

编辑：由于WebGet存在，我认为你不想要肥皂终点。下面是一个支持soap和WebGet的配置。我不知道Azure与标准IIS的不同之处，但您应该使用相对地址来进行服务。 IIS将仅支持服务配置中的相对地址。

<system.serviceModel>
    <services>
        <service name="Service1" behaviorConfiguration="Service.Behavior">
            <endpoint address="Service1"
                      binding="basicHttpBinding"
                      contract="IService1"
                      bindingNamespace = "http://example.com"

此WCF配置是否导致我的400错误请求？
