            filename.addEventListener('change', function (){
            // Creating a FileReader object using the constructor.
    
            const filereader = new FileReader();
            // Reading a file as plain text
    
            filereader.readAsText(filename.files[0]);
            // Call this function to print the contents of the file
            // once the file has been read.

I think i have found a solution for you :-我想我已经为您找到了解决方案：-

try this尝试这个

/* global FileReader */

$w.onReady(function () {
     const fileReader = new FileReader();

fetch('https://static.wixstatic.com/media/e3b156_8646d72618e3420db36dba9156d0b8e7~mv2.jpg/v1/fit/w_512,h_586/o_0.jpeg')
        .then(response => response.blob())
        .then(blob => fileReader.readAsArrayBuffer(blob));

    fileReader.onload = function () {
        // your buffer array here. But why you need it? )))
        console.log(fileReader.result);
    }
})
