C#中使⽤JWT实现WabApi的权限控制⾸先需要在你的项⽬中引⼊JWT，你只需要在nuget中安装JWT，JWT依赖于.NET Framwork 4.6以上版本，所以你的webapi项⽬也需要.NET Framwork4.6以上版本，我这⾥做法如下： 1 /// 2 /// 验证是否含有token 3 /// 4 public class ApiAuthorizeAttribute : AuthorizeAttribute 5 { 6 private UserIBLL userBll = new UserBLL(); 7 /// 8 /// 验证是否授权 9 /// 10 /// 11 /// 12 protected override bool IsAuthorized(HttpActionContext actionContext)13 {14 //获取header头信息15 IEnumerable tokenInfo;16 Values("Token", out tokenInfo);17 IEnumerable id;18 Values("id", out id);19 if (tokenInfo != null)20 {21 string token = ()[0];22 var userid = ()[0];23 if (!OrEmpty(token))24 {25 try26 {27 UserEntity userEntity = ityByUserId(()[0]);28 if (userEntity == null)29 {30 return false;31 }32 IJsonSerializer serializer = new JsonNetSerializer();33 IDateTimeProvider provider = new UtcDateTimeProvider();34 IJwtValidator validator = new JwtValidator(serializer, provider);35 IBase64UrlEncoder urlEncoder = new JwtBase64UrlEncoder();36 IJwtDecoder decoder = new JwtDecoder(serializer, validator, urlEncoder);37 var json = (token, , verify: true);38 if (OrEmpty(json))39 {40 return false;41 }42 var newModel = ct();43 if (newModel.F_UserId != userEntity.F_UserId || != )44 {45 return false;46 }47 return true;48 }49 catch (Exception)50 {51 return false;52 }53 }54 }55 return false;56 }57 }
