我正在阅读此处的 React.js 教程：http ://facebook.github.io/react/docs/tutorial.html
使用 AJAX 和 post 方法向页面添加评论时，我得到501 (Unsupported method ('POST')).
我知道你不能在本地发送一个 JSON post 命令（类似于这个问题：angularjs $http.post 导致 501 Unsupported method ('POST')），我正在使用python -m SimpleHTTPServer.
如何为 JSON 文件设置 Web 服务端点？
如果您查看github上的reactjs/react-tutorial，有一个使用 node.js 的示例服务器：
git clone git@github.com:reactjs/react-tutorial.git && cd react-tutorial
npm install
node server.js
这是 server.js 文件。
var fs = require('fs');
var path = require('path');
var express = require('express');
var bodyParser = require('body-parser');
var app = express();
var comments = JSON.parse(fs.readFileSync('_comments.json'));
app.use('/', express.static(path.join(__dirname, 'public')));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({extended: true}));
app.get('/comments.json', function(req, res) {
res.setHeader('Content-Type', 'application/json');
res.send(JSON.stringify(comments));
});
app.post('/comments.json', function(req, res) {
comments.push(req.body);
res.setHeader('Content-Type', 'application/json');
res.send(JSON.stringify(comments));
});
app.listen(3000);
console.log('Server started: http://localhost:3000/');
