nodejs的增删改查

1.新建一个jwttest.router.js

引入toast

const {success,fail} = require("../toast"); const jwt = require("jsonwebtoken"); const key="web";
module.exports = function (router){     router.post("/login",async ctx=>{         const {name,pwd} = ctx.request.body;         if(name==="admin" && pwd==="123456"){             const token = jwt.sign({name:"admin"},key,{expiresIn:300})             return success(ctx, "Bearer " + token);         }else{             return fail(ctx,"账号和密码不正确");         }     }).get("/data",async ctx=>{         return success(ctx,{});     })
};   在app.js中引入jwttest // 引入类 const Koa =require('koa'); // 引入koa-router const Router =require('koa-router'); // 引入koa-body const koaBody=require('koa-body');
const tagRouter =require("./routers/tag.router"); const userRouter =require("./routers/user.router"); const contentRouter =require("./routers/content.router"); const jwtRouter =require("./routers/jwttest.router"); const {fail} = require("./toast"); const jwt = require("jsonwebtoken"); const key="web";
// 创建对象 const app =new Koa(); app.use(koaBody({     strict:false })); app.use(async (ctx,next) =>{     const exp = [         '/login',         '/',         'register',     ]; //不需要验证的地址     if(exp.includes(ctx.url)){         await next();         return;     }
    console.log(ctx.headers)     const authorization = ctx.headers.authorization;     if(!authorization){          return fail(ctx,"请添加 token 信息");     }     const token = authorization.split(' ')[1];     try{          const user =jwt.verify(token,key);          if(user.name==="admin"){             await next();          }else{             return fail(ctx,"权限不足");         }     }catch(error){         return fail(ctx,error);     } })
const router =new Router({// 可以传递参数配置路由前缀 });
tagRouter(router); userRouter(router); contentRouter(router); jwtRouter(router);   app.use(router.routes()); app.use(router.allowedMethods({ })); // localhost:3000 app.listen(8000,()=>{    console.log("http://localhost:8000"); });   最后通过text.http查看是否显示正确 @url =http://localhost:8000 @json=Content-Type: application/json
@auth=Authorization: Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJuYW1lIjoiYWRtaW4iLCJpYXQiOjE2Mzg1MjA5MDAsImV4cCI6MTYzODUyMTIwMH0.PAvCI6TsrzYs7_P4e4v_ieLlLJY-iT0ro42oTYFhV1Q
