跨域情况下shiro多类型用户认证和授权

爱喝酒的幸福人 2023-02-10 阅读 68
javaJava后端开发yyds干货盘点

跨域的管理主要是将用户登陆后的jsId返回到前端，前端以token的形式传回的时候，重写session认证器，以区分不同的用户。由于跨域有预检机制，不携带自定义参数，所以重写shiro过滤器，放行预检请求。

配置过类型用户的认证和授权，首先：要自定义token继承shiro的usernameAndpasswordToken，然后添加标识字段。然后在选择认证器的时候，重写realm的认证中心分配器，根据token中的标识，返回指定的认证器进行登陆。登陆时priciple传入用户实体，以便于在进行分配授权认证器的时候识别出指定的授权方法。
