Express介绍： Express 是NodeJS里最好的网站开发框架，性能很不错，并且可以与其它一些框架集成。 下载安装Express npm install -g express 初始化Express项目 mkdir mysite && cd mysite express . 这时候就会发现mysite目录中出现了项目的目录结构，但还需要安装相关依赖包： npm install -d 这时候会下载安装相关的依赖包到当前node_modules目录下，然后可以试下启动这个项目： node app.js 打开浏览器，访问http://localhost:3000，或者直接下面命令： curl http://localhost:3000 结果会出现"Welcome to Express"的信息。 一些细节解释 安装的时候，使用-g 是说安装到全局环境中，而不是当前目录（项目）中。 express命令，-h 参数可以查看帮助，初始化项目时，可以指定是否需要session、所使用的模板框架和CSS框架。 项目初始化完成后，一定要记得安装相关依赖，否则无法运行，报找不到某模块。 修改app.js 配置项目 默认的模板框架是jade, CSS框架是plain css。 Express手册： http://expressjs.com/guide.html 来源： oschina 链接：

问题 I am building a node express app for storing recipes. Via a 'new recipe' html form, users can add as many ingredients as they need, which are dynamically displayed via jquery and stored in an 'ingredients' array. Because I can't send this array via HTTP, I'm trying to send a new recipe object via an AJAX post request. I have limited experience with AJAX, and I cannot understand why the post request is not working at all. Here's my front end jquery: script type="text/javascript"> //$(document)
