angular.js - Angular中如何从一个图片路径读取出byte数组?

Question

如题
现在得到一个

file:///var/mobile/Containers/Data/xxxx.jpg

需要加这个路径的图片读取成byte数组并传给服务器，请问应该如何实现？

PS:
尝试下使用$http读取这个文件

$http.get('file:///var/mobile/Containers/Data/xxxx.jpg')
.success(function(response) {
    alert(response);
});

不知道这里读出的response是什么？

The following method can convert the requested image result into blob. As for how you want to use it afterwards, it’s up to you

$http.get('http://localhost:9000/test.png')
    .success(function(data) {
        var blob = new Blob([data], {
            type: 'image/png'
        });
        console.log(blob);
    });

I only tried the method of serving images on the server. I don’t know if it will work if you load local images. Because of the content-type是image/png in the response header of the server’s serve image, I don’t know what’s going on when loading local files
