下面是一个将Uint8Array转换为 Base64 字符串的示例: functionuint8ArrayToBase64(uint8Array:Uint8Array):string{letbinaryString='';for(constbyteofuint8Array){binaryString+=String.fromCharCode(byte);}returnbtoa(binaryString);}//
3. 将字节数组转换为Base64字符串 在TypeScript中,我们可以使用btoa函数或Buffer对象来将字节数组转换为Base64字符串。下面我们将分别介绍这两种方法的实现。 3.1 使用btoa函数 在浏览器环境下,可以直接使用btoa函数将字节数组转换为Base64字符串。示例代码如下所示: constbyteArray=Uint8Array.from([72,101,108,108...
// atob(...) is not present, other answers suggest to use Buffer for conversion const binary: string = Buffer.from(buffer, 'base64').toString(); const arrayBuffer: ArrayBuffer = new ArrayBuffer(binary.length); const uintArray: Uint8Array = new Uint8Array(arrayBuffer); for (let i: numbe...

要从ArrayBuffer获取Int8Array,可以使用以下代码: 代码语言:txt 复制 const buffer = new ArrayBuffer(8); // 创建一个长度为8的ArrayBuffer对象 const int8Array = new Int8Array(buffer); // 使用ArrayBuffer创建一个Int8Array对象 // 通过索引操作Int8Array int8Array[0] = 10; int8Array[1] = 20; co...
encode(data); let base64result = ''; dataUint8Array.forEach((byte) => { base64result += String.fromCharCode(byte); }); return btoa(base64result); } // 测试 const originalText = "Hello, TypeScript!"; const base64Encoded = encodeToBase64(originalText); console.log(`原始文本: ...
而 "void" 类型用于表示函数不返回任何值。任何值赋予 "void" 类型时，通常用于强调函数的副作用而非...
