Easy creation of nodejs servers (2): Component Analysis of nodejs servers,
Next to the previous section, let's analyze the Code:
The http module that comes with the first line request (require) Node. js and assigns it to the http variable.
Next, we will call the function createServer provided by the http module.
This function will return an object, which has a method called listen. This method has a numeric
NodeJs creates basic HTTP servers and nodejs creates servers.The content is simple, but the basics are written and shared with you. If you forget it, you can find it.
Create a server with the following code:
Var http = require ('http'); http. createServer (function (req, res) {res. writeHeader (200, {'content-type': 'text/html'}); res. write ('
Enter http: // 127.0.01: 3000 to access
The port is the port value entered at listen in the code.
