我在Node.JS应用程序中使用路由，当我尝试从浏览器中打开其中一个路由时，出现错误

Question

That's my app. When I try to open ip/delete I get an error

Cannot GET /delete

I'm following this tutorial, https://www.tutorialspoint.com/nodejs/nodejs_express_framework.htm

var express = require('express');
var app = express();

app.use(express.static('public'));

app.get('/', function(req, res) {
        console.log("Got a GET request");
        res.send('GBArena Labs');
})

app.post('/', function(req, res) {
        console.log("Got a POST request");
})

app.delete('/delete', function(req, res) {
        res.send('Delete');
        console.log("Got a DELTE request");
})

app.listen(8081);

Answer 1

You can't navigate to a DELETE. You have to send a DELETE request. In example :

<a href="/delete">My delete link<a/> will be sent as a GET request and not a DELETE.

In order to hit your delete endpoint, you would have to use a ajax library like jquery $.ajax and using

$.ajax({
    url: '/delete',
    type: 'DELETE',
    success: function(result) {
        // Do something with the result
    }
});

from the client side.

There are many ways, but i would suggest you looking into : HTTP verbs

Answer 2

您可能需要在没有/ delete的情况下调用路由，并使用REST客户端（例如Fiddler或Postman）的HTTP动词DELETE。

Answer 3

First, you try to access by ip/delete endpoint. I assume you will get an error because you are not using the port of the application (you have to access by ip:port/delete)

You have to know about the usage of DELETE method. When you try to directly access the ip/delete endpoint, your browser will set it as GET method while in your application, there is not GET method for ip/delete
