How to use render and send in node.js

This time I will show you how to use render and send in node.js, and what are the precautions for using render and send in node.js. The following is a practical case. Let’s take a look.

If you want to write a quick test page, of course you can use res.send(). This

function will automatically help us set the Content-Type header and 200status code based on the content. send() can only be used once, the same as end. How is it different from end? Ability to automatically set MIME types.

If you want to use different status codes, you can:

res.status(404).send('Sorry, we cannot find that!');

If you want to use different Content-Types, you can:

res.set('Content-Type', 'text/html');

render：

var express = require("express");
var app = express();
app.set("view engine", "ejs");
app.get("/", function (req, res) {
 res.render("haha", {news:[]});
});
app.listen(3000);

send：

app.get("/check", function (req, res) { 
 res.set('Content-Type', 'text/html'); 
 res.send({ 
 "user" : "ok" 
 }); 
});
