c#⾃定义验证登录（Authorize）我们的项⽬本来是⽤azure的auth认证，是⽤过程中发现登录速度太慢了，所以还是⾃⼰搞⼀个吧，没想到搞起来挺简单的，不是⽤⼀个专门的认证服务器哈，就是⼀个简单的⼯具类。验证是否登录的类 ///

/// 认证类继承 ///

public class RequestAuthorizeAttribute : AuthorizeAttribute { public override void OnAuthorization(HttpActionContext actionContext) { // 是否不需要验证或者已经登录 if (SkipAuthorization(actionContext) || IsLogin(actionContext)) return; se = GetResponse(); } ///

/// 返回信息接⼝ ///

private HttpResponseMessage GetResponse() { var response = ServiceResponse.WarningResponse(401, _NoLogin, false); return ResponseMessage(response); } ///

/// 判断是否匿名使⽤接⼝ ///

private static bool SkipAuthorization(HttpActionContext actionContext) { if (!tomAttributes().Any()) return tomAttributes().Any(); return true; } ///

/// 是否已经登录 ///

private bool IsLogin(HttpActionContext actionContext) { var authorization = ng(); // MD5值 if (ization != null) { authorization = ng(); } var user = rent(authorization); return user != null; } }获取header值：参考资料：代码如下：

private bool IsLogin(HttpActionContext actionContext) { var token = ng(); // MD5值 var openId = ; // MD5值 Values("Token", out var tokens); Values("OpenId", out var openIds); if (ull() && () && ull() && ()) { token = rDefault(); openId = rDefault(); var cache = he(token); if (ull())//如果缓存中存在该token对应的值，说明已经登录了 return true; //获取⽤户 var strUserUrl = ode(tings["sso_req_user_url"]); var reqUserUrl = (strUserUrl, openId, token); var reqUser = (reqUserUrl) as HttpWebRequest; = "get"; tType = "application/json"; var resUser = ponse() as HttpWebResponse; //以流的形式读取，返回的就是字符串的json格式 StreamReader readerUser = new StreamReader(ponseStream()); var resUserData = End(); if (Code == ) { var suser = alizeObject(resUserData); var userId = (); he(token, userId); return true; } else { return false; } } return false; }

使⽤登录接⼝数据缓存处理，获取到⽤户信息后，⽣成guid作为token，每次登录都会重新⽣成token，返回给请求来源，web端只保存token值即可，每次请求的时候把token放到header⾥⾯。BaseApiController处理，获取header⾥⾯的token值，把⽤户信息放到缓存⾥⾯，从缓存中获取后放到基类⾥⾯的model中，⼦类都可以使⽤⽤户信息。 [RequestAuthorize] public class BaseApiController : ApiController { ///

/// 当前⽤户信息实体 ///

public OperatorModel CurrentUserModel { get { var values = ues("authorization"); var authorization=ng(); if (values != null && > 0) authorization = values[0]; var currentUserModel = rent(authorization); if (currentUserModel == null) { currentUserModel = new OperatorModel { LoginName = "admin" }; } return currentUserModel; } } } web端使⽤token（VUE）token帮助类import Cookies from 'js-cookie'const TokenKey = 'hs_t'export function getToken() { return (TokenKey)}export function setToken(token) { return (TokenKey, token)}export function removeToken() { return (TokenKey)}
