Javascript：获取 api 与 AJAX

Question

I have this code

fetch('http://example.com/movies.json')
  .then(response => response.json())
  .then(data => console.log(data));

Is using Fetch API for a request like in the code above considered as an AJAX request?

I a request considered an AJAX request only if we use the XMLHttpRequest object ?

Answer 1

是的，有几种方法可以发送异步请求，例如 jQuery、axios、Fetch API 或 XMLhttprequest。

Answer 2

fetch is an ajax request.

but fetch is a simple api and have not, so I recommended fatcher

fatcher is a lightweight HTTP request library based on fetch , allows us to use native fetch for web requests in a browser and NodeJS environment.

It is wrapped using the native fetch , we require that browsers or NodeJS support fetch when we use it.

• Fetch support is already pretty good in modern browsers, so we don't have to worry about FETCH compatibility
• In NodeJS, fetch already has some support starting with '18.0.0'

Fatcher aims to embrace the fetch of the standard library and at the same time provide some functions that cannot be provided in fetch , as well as make the function better expand and reuse.

import { fatcher, isFatcherError } from 'fatcher';

fatcher({
    url: '/',
})
    .then(result => {
        // Response
        const { data, status } = result;
    })
    .catch(err => {
        // Catch Fatcher Error
        if (isFatcherError(err)) {
            // Request successfully. But response status code is not 2xx.
            console.error(err.toJSON());
            return;
        }

        // This is other errors.
    });
