使用cURL或Postman时，一切都可以正常使用
curl -d 'username=Johny Sample&title=My First Post&description=We want some help cleaning up after the hurricane&postID=Johny Sample_1' http://localhost:3000/NewPost
请求结果
{"posterID":"Johny Sample","title":"My First Post","description":"We want some help cleaning up after the hurricane"}
服务器结果
req.body == {
username: 'Johny Sample',
title: 'My First Post',
description: 'We want some help cleaning up after the hurricane',
postID: 'Johny Sample_1'
}

服务器端代码
app.post('/NewPost', function (req, res) {
console.log(req.body);
var post = {};
post.posterID = req.body.username;
post.title = req.body.title;

您需要为POST
添加HTTP标头xhttp.open("POST", "http://localhost:3000/NewPost", true);
xhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
var sendData = gatherData();
xhttp.send(sendData);
