javascript node.js render

The following is what I have compiled for you about the differences and usage methods of render and send in node.js. Interested students can take a look.

In most cases, res.render() is used to render content, which will be rendered according to the template file in views. If you don’t want to use the views folder and want to set the folder name yourself, then app.set("views","aaaa");

If you want to write a quick test page, of course you can use res.send() . This function will automatically set the Content-Type header and 200 status code for us 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!');
Copy after login

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

   res.set('Content-Type', 'text/html');
Copy after login

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);
Copy after login

send:

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

The above is what I have compiled for you about the differences and usage methods of render and send in node.js. I hope it will be helpful to you in the future.
