这是WCF配置导致我的400错误请求吗

本文关键字：错误 请求 我的 WCF 配置 这是 | 更新日期: 2023-09-27 18:20:29

我有一个WCF应用程序，作为Azure中的网络角色托管，具有以下配置。当我试图访问浏览器中的三个服务wsdl中的任何一个或试图设置代理时，我会收到一个400坏请求。

            </services>
            <behaviors>
                <serviceBehaviors>
                    <behavior name="MetaBehavior">
                        <serviceDebug includeExceptionDetailInFaults="true" />
                        <serviceMetadata httpGetEnabled="true"/>
                        <serviceThrottling maxConcurrentSessions="90" />
                    </behavior>

        <system.webServer>
            <modules runAllManagedModulesForAllRequests="true"/>
        </system.webServer>
    </configuration>

我很确定我的配置不正确，但我需要一点关于什么是不正确的指导。

接口定义为：

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

这是WCF配置导致我的400错误请求吗

您使用了错误的绑定，请尝试webHttpBinding而不是basicHttpBinding。您的合约设置为WebGet，这是WCF对准REST服务的接受。BasicHttpBinding仅适用于基于soap的绑定（因此出现"Bad request"异常）。

编辑：由于存在WebGet，我认为您不需要soap端点。下面是一个同时支持soap和WebGet的配置。我不知道Azure与标准IIS有多大区别，但您可能应该为您的服务使用相对地址。IIS将只支持服务配置中的相对地址。
