推荐答案

服务的端点未正确配置为接收JSON输入.为了兑现 [WebInvoke] 属性，您的端点需要具有 webHttpBinding ，并且端点行为还应具有< webHttp类型/>

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/>

一种确保正确配置的简单方法是使用.svc文件上的 Factory 属性.类似于下面的示例:

One easy way to ensure that it's properly configured is to use the Factory attribute on the .svc file. Something like the example below:

<%@ ServiceHost Language="C#" Debug="true"
                Service="YourNamespace.YourServiceClass"
                Factory="System.ServiceModel.Activation.WebServiceHostFactory" %>
