下载jwt        配置jwt

pnpm i egg-jwt

 plugin.js

/** @type Egg.EggPlugin */
module.exports = {jwt:{enable:true,package:'egg-jwt'}
};

config.default.js

config.jwt = {secret:"hakurei77"    //密钥}

创建中间层

        app -> middleware

//检查token
module.exports = (options) => {return async function jwtErr(ctx, next) {const token = ctx.request.header.authorization;let decode = '';if (token) {try {// 解码tokendecode = ctx.app.jwt.verify(token, options.secret);await next();console.log('decode======>',decode);} catch (error) {ctx.status = 401;ctx.body = {message: error.message,};return;}} else {ctx.status = 401;ctx.body = {message: '没有token',};return;}};}

 Controller层

async ...() {const { ctx , app } = this;const result = await             this.ctx.service.userService....(this.ctx.request.body ,app);ctx.body = result
}

Service层

。。。
const token = app.jwt.sign({UserName: user.UserName,Password: user.Password
},app.config.jwt.secret,{expiresIn:"15s"})    //里面放持续时间
result = {"code": 200,"msg": "成功","data": {"TOKEN": token}
}

路由层

module.exports = app => {const { router, controller,middleware } = app;const jwtErr = middleware.jwtErr(app.config.jwt)router.post("/main" ,jwtErr ,controller.userController.abc)
};
