Nodejs rest api开发

本文利用nodejs+restify 开发rest api，非express 等rest服务。去除了多余的模板内容。

操作步骤：

1.下载依赖：

cnpm install restify restify-plugins restify-errors --save
复制代码

2.hello-world：

/**
 * Module Dependencies
 */
const config = require('./config');
const restify = require('restify');
const restifyPlugins = require('restify-plugins');
 
/**
  * Initialize Server
  */
const server = restify.createServer({
	name: config.name,
	version: config.version,
});
 
/**
  * Middleware
  */
server.use(restifyPlugins.jsonBodyParser({ mapParams: true }));
server.use(restifyPlugins.acceptParser(server.acceptable));
server.use(restifyPlugins.queryParser({ mapParams: true }));
server.use(restifyPlugins.fullResponse());
 
/**
  * Start Server, Connect to DB & Require Routes
  */
server.listen(config.port, (ctx,res) => {
	 // require('./routes')(server);
	 console.log(`Server is listening on port ${config.port}`);
});
复制代码

3.开启路由，routes文件中创建index.js，同时开启上方的注释。

/**
 * Module Dependencies
 */
const errors = require('restify-errors');
 
 
module.exports = function(server) {
 
	/**
	 * POST
	 */
	server.post('/todos', (req, res, next) => {
		if (!req.is('application/json')) {
			return next(
				new errors.InvalidContentError("Expects 'application/json'"),
			);
		}
 
		let data = req.body || {};
 
		res.send("todos post ");
		next();
	
	});
 
	/**
	 * LIST
	 */
	server.get('/todos', (req, res, next) => {
		res.send("gete todos....");
		next();
	});
 
	/**
	 * GET
	 */
	server.get('/todos/:todo_id', (req, res, next) => {
		
	});
 
	/**
	 * UPDATE
	 */
	server.put('/todos/:todo_id', (req, res, next) => {
		
	});
 
	/**
	 * DELETE
	 */
	server.del('/todos/:todo_id', (req, res, next) => {
		
	});
}; 
复制代码

4.成功搭建rest api
