正文解析器在快速路由器中记录空对象

问题描述

由于某种原因，我可以在路线上的快递服务器中看到我的req.body

for some reason I can see my req.body in my express server on my route

req body is [Object: null prototype] { '{"password":"xxxxxxxx"}': '' }

但是当我登录req.body.password(对象密钥)时，我得到了

but when I log req.body.password (the object key) I get

req body is undefined

这是我的快递应用中供参考的索引路由器

here's my index router for reference in my express app

var express = require('express');
var router = express.Router();
var bodyParser = require('body-parser')
const path = require('path');

/* GET adminPanel. */
router.post('/authenticate', function(req, res, next) {

  console.log('req body is',req.body.password)
  res.send("passconfirmed");
});

module.exports = router;

推荐答案

要访问主体的内容，请在处理程序之前在中间件中解析传入的请求主体，该处理程序可在req.body属性下找到.

To access the content of the body, Parse incoming request bodies in a middleware before your handlers, available under the req.body property.

您需要安装 body-parser 软件包.

npm i body-parser-保存

现在在项目中导入 body-parser .应该在定义的路由功能之前调用它.

Now import body-parser in your project.It should be called before your defined route functions.

const express = require('express');
const router = express.Router();
const bodyParser = require('body-parser')
const path = require('path');

app.use(bodyParser.json());
app.use(bodyparser.urlencoded({ extended : true }));

/* GET adminPanel. */
router.post('/authenticate', function(req, res, next) {

  console.log('req body is',req.body.password)
  res.send("passconfirmed");
});

module.exports = router;
