2、cmd代开命令行,转到上面新建文件的目录下,输入:node example.js (服务器启动后效果如下)3、上面说了这是个Web服务器,所以在浏览器里可以直接输入http://127.0.0.1:1337/,大家将会看到hello world的界面:说明:从上面一个简单的例子想必大家已经看出node.js的一个优势,即只用简单的几行代码就构建了一个web...
生成名为example的可执行文件,然后将这个可执行文件放到系统环境变量中,然后打开控制台,输入example,看到最后输出"Hello World"。 确保这个可执行文件在任意路径下都能访问。 我们分别用spawn和execfile来调用example文件。 首先是spawn。 代码语言:javascript 复制 constspawn=require('child_process').spawn;constls=spaw...

hello-world-server.js文件就是一个简单的web服务器,右键选择“运行方式”->"Node Application" 控制台提示“Server running at http://127.0.0.1:1337/”在浏览器查看的效果如下: 三、第一个Node.js程序 在VSCode中创建一个新的项目,如nodedemo1:

Node's goal is to provide an easy way to build scalable network programs. In the "hello world" web server example above, many client connections can be handled concurrently. Node tells the operating system (throughepoll,kqueue,/dev/poll, orselect) that it should be notified when a new conn...
