javascript - Problems with ES7 fetch to obtain data

Question

fetch('/static/data/data.json')
            .then(data => {
                console.log(data);
            })

But no data was returned to me. Where is the data?

Answer 1

First of all, Fetch API is a Web API and has nothing to do with ES7.

Regarding the Fetch API, it needs to cooperate with Request and Response. Here is a more detailed tutorial on how these APIs cooperate to complete the request.

Answer 2

See MDN:
https://developer.mozilla.org... To make a fetch request
you should use:

data.blob()

Answer 3

fetch('/static/data/data.json')

        .then(data =>data.json())
        .then(json=>console.log(json))
