The endpoint for your service is not properly configured to receive JSON input. In order for the [WebInvoke]attribute to be honored, your endpoint needs to have the webHttpBinding, and it should also have an endpoint behavior of type <webHttp/>
您的服务的端点未正确配置为接收 JSON 输入。为了使该[WebInvoke]属性受到尊重，您的端点需要具有webHttpBinding，并且还应该具有类型为的端点行为<webHttp/>
One easy way to ensure that it's properly configured is to use the Factoryattribute on the .svc file. Something like the example below:
确保正确配置的一种简单方法是使用Factory.svc 文件上的属性。类似于下面的例子：
<%@ ServiceHost Language="C#" Debug="true"
Service="YourNamespace.YourServiceClass"
Factory="System.ServiceModel.Activation.WebServiceHostFactory" %>
