jQuery의 ajax 메소드를 사용하여 이미지를 Blob으로 검색하는 방법은 무엇입니까?

var xhr = new XMLHttpRequest();
xhr.onreadystatechange = function() {
    if (xhr.readyState == 4 && xhr.status == 200) {
        // this.response contains the blob
        handler(this.response);
    }
};
xhr.open('GET', 'http://jsfiddle.net/img/logo.png');
xhr.responseType = 'blob';
xhr.send();

jQuery.ajax({
    url: 'https://images.unsplash.com/photo-1465101108990-e5eac17cf76d?ixlib=rb-0.3.5&q=85&fm=jpg&crop=entropy&cs=srgb&ixid=eyJhcHBfaWQiOjE0NTg5fQ%3D%3D&s=471ae675a6140db97fea32b55781479e',
    cache: false,
    xhr: function() {
        var xhr = new XMLHttpRequest();
        xhr.responseType = 'blob';
        return xhr;
    },
    success: function(data) {
        var img = document.getElementById('img');
        var url = window.URL || window.webkitURL;
        img.src = url.createObjectURL(data);
    },
    error: function() {
        // Handle error
    }
});
