1、post数据结构:
Form Data: type:post name:post发送url参数
2、js代码实现
var xhr = new XMLHttpRequest(); xhr.open('post', 'http://localhost:3000/post', true); xhr.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded'); xhr.send(urlParams(data)); xhr.onload = function () { if (xhr.status === 200) { var text = xhr.responseText; if (success) success(JSON.parse(text)); } else { if (error) error(xhr); } };
3、后端获取数据(Nodejs)
var express = require('express'); var app = express(); var bodyParser = require('body-parser'); var urlencodedParser = bodyParser.urlencoded({ extended: false }); app.post('/urlPost', urlencodedParser, function(req, res) { res.header('Access-Control-Allow-Origin', '*'); console.log('get application/x-www-form-urlencoded Params: ', req.body); res.json({result: 'success', data: req.body}); });
