Question

我是节点js的新手，在使用body-phraser时，我收到了错误： ReferenceError: status is not defined 。代码如下所示当json发布到 localhost：3000 / 产品时，以下错误似乎正在上升，但我无法弄清楚为什么会发生这种情况。是否由于我的代码中的错误而发生引用错误：
我得到的错误是：

ReferenceError: status is not defined

我使用的代码：

router.post('/',(req,res,next) =>{
    const product ={
        name :req.body.name,
        price :req.body.price
    };
    res.status(201).json({
        messsage:'Handelling post requests to /products',
        createdproduct:product
    });
});

module.exports =router;

请将正文光标添加到路由器，如下面的行

const router = require("express").Router();
const bodyParser = require("body-parser");
router.use(bodyParser.json());

您必须使用＆＃39;使用＆＃39;将身体解析器添加到中间件。上面的方法和你的代码，

＆＃13;

router.post('/',(req,res,next) =>{
    const product ={
        name :req.body.name,
        price :req.body.price
    };
    res.status(201).json({
        messsage:'Handelling post requests to /products',
        createdproduct:product
    });
});
