相比application/x-www-form-urlencoded multipart/form-data不仅可以上传键值对还可以上传文件
application/json
express -e json
# cd json
cnpm i
vim routes/index.js
var express = require('express');
var router = express.Router();
router.post('/', function (req, res, next) {
res.send(req.body);
});
module.exports = router;
- 测试
nodemon
curl -X POST -H 'Content-Type:application/json' -d '{"name":"木木","id":"yl33643"}' localhost:3000 | json
{
