console.log(`Decoded string: [${validUTF16StringDecoded}]`);The following steps explain what this code does to encode the string: 使用TextEncoder接口将UTF-16编码的JavaScript字符串转换为UTF-8编码的字节流,可通过TextEncoder.encode()实现。 这将返回一个Uint8Array,这是JavaScript中较少使用的数据类型,...

【Base64 Encoding / Decoding in Node.js】 Here is how you encode normal text to base64 in Node.js: varb=newBuffer('JavaScript'); vars=b.toString('base64'); // SmF2YVNjcmlwdA== And here is how you decode base64 encoded strings: ...
btoa(String.fromCharCode(...new TextEncoder().encode('中文'))) // 值: '5Lit5paH' 解码 对于解码,首先我们使用atob()将上面得到的 base64 编码转换成字符串。 atob('5Lit5paH') // 值: 'ä¸æ\x96\x87' 接下来我们需要将这个字符串转换成一个Uint8Array二进制字节流,这里我们可以使用...
In Node.js, you can use theBufferclass to encode and decode Base64 data without the need for thebtoa()andatob()functions. Here's an example: constbinaryString="codedamn is awesome!";constbase64Encoded=Buffer.from(binaryString).toString('base64');console.log(base64Encoded);// Y29kZWRhbW...
return decodeURIComponent(atob(str).split('').map(function (c) { return '%' + ('00' + c.charCodeAt(0).toString(16)).slice(-2); }).join('')); } };let encoded = Base64.encode("哈ha"); // "5ZOIaGE="let decoded = Base64.decode(encoded); // "哈ha"...
var bytes = new Uint8Array( buffer ); var len = bytes.byteLength; for (var i = 0; i < len; i++) { binary += String.fromCharCode( bytes[ i ] ); } return window.btoa( binary ); } 怎么把字符串再转回base64(gbk编码格式)???
