通过网上查看相关WebAPI接口验证的方法，整理了一下，直接上代码，功能不复杂，有问题留言，

不需要做校验的接口，加一个标签
//----------------------------------------------------------------------- // <copyright file="ApiAuthenticationFilter.cs" company="FenSiShengHuo, Ltd."> // Copyright (c) 2018 , All rights reserved. // </copyright> //----------------------------------------------------------------------- using System.Web.Http.Filters; namespace DotNet.WeChat.API.Attribute { /// <summary> /// ApiNoAuthenticationFilter /// 不做授权检查 /// /// 2018-07-19 版本：1.0 JiShiYu 创建。 /// /// <author> /// <name>JiShiYu</name> /// <date>2018-07-19</date> /// </author> /// </summary> public class ApiNoAuthenticationFilter : AuthorizationFilterAttribute { } }
全局校验，放在哪里，你懂的
- public static class WebApiConfig
- {
- public static void Register(HttpConfiguration config)
- {
-
-
-
-
- // 接口授权检查
- config.Filters.Add(new ApiAuthenticationFilter());
-
-
- }
- }
测试效果
