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
