我正在尝试从数组缓冲区构造一个Blob,原始来自二进制字符串。它在Firefox和Firefox中运行良好Chrome,但我不知道Safari&戏
这是我的问题的简化版本: http://plnkr.co/edit/sfEEHf?p=preview
// 1x1 red PNG pixle
base64 = "iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAYAAAAfFcSJAAAADUlEQVQIW2P8z8DwHwAFBQIAHl6u2QAAAABJRU5ErkJggg==";
byteString = atob(base64);
// convert binary to array buff so we can construct a blob later
arrayBuffer = new ArrayBuffer(byteString.length);
intArray = new Uint8Array(arrayBuffer);
for (i = 0; i < byteString.length; i += 1) {
intArray[i] = byteString.charCodeAt(i);
}
// construct blob
blob = new Blob([intArray], {type: "image/png"});
console.log(blob.size); // suppose to be 70 (its 19 in safari)
答案 0 :(得分:11)
在Safari中,您需要使用TypedArray上的'buffer'属性,即:
blob = new Blob([intArray.buffer], {type: "image/png"});
它会起作用。
