针对“jwt is null or empty string”的问题,我们可以从以下几个方面进行检查和处理: 1. 检查JWT是否为null 当JWT为null时,通常意味着在生成或传递JWT的过程中出现了问题。以下是几种可能的情况及相应的处理建议: 生成JWT时未正确赋值:确保在生成JWT的代码逻辑中,JWT字符串被正确赋值并返回。 传

JSON Web Token(JWT)是目前最流行的跨域身份验证解决方案。通过客户端保存数据,而服务器根本不保存会话数据,每个请求都被发送回服务器。 JWT是这种解决方案的代表。 一、跨域身份验证 1、Internet服务无法与用户身份验证分开。一般过程如下: (1)用户向服务器发送用户
