在JavaScript中,可以使用atob(对于非URL安全的Base64字符串)或Uint8Array结合TextDecoder(对于URL安全的Base64字符串)来解析Base64字符串为Uint8Array。 javascript function base64ToUint8Array(base64) { const binaryString = atob(base64); // 将Base64字符串解码为二进制字符串 const length = binaryString.len...

下面是将字节数据转换为 Base64 的步骤: 详细步骤 1. 准备字节数据 首先,我们需要准备一些字节数据。字节数据通常保存在Uint8Array或者普通数组中。接下来我们创建一个简单的字节数组。 AI检测代码解析 // 创建一个字节数组letbyteArray=newUint8Array([72,101,108,108,111]);// 对应 "Hello" ...
function toBase64(arrayBuffer) { var binary = ''; var bytes = new Uint8Array(arrayBuffer); var len = bytes.byteLength; for (var i = 0; i < len; i++) { binary += String.fromCharCode(bytes[i]); } return window.btoa(binary); ...
