如何从缓冲区数组接收字符串为 UTF-8（java 到 javascript）？

Question

i am trying to convert a small piece of code into javascript, everything is going well except for this part

new String(encode, Charsets.UTF_8);

I suppose this is creating a string from encoded hash, what i have in javascript is

const encoderUTF8 = new TextEncoder('utf-8');
const utf8 = new Uint8Array(encode.length);

const encoded = encoderUTF8.encodeInto(encode, utf8);

When i run it i get an error that says The "src" argument must be of type string. Received an instance of Buffer The "src" argument must be of type string. Received an instance of Buffer . The encode variable is a strange hash looking like this dD${��d�N��t�\���P� which is generated like so

const encode = Buffer.from(hash, 'base64');

Can someone please help me get this part together? All I need is to figure out that new String part.

Answer 1

I wrote one of the functions wrong, i should have base64 encoded instead of decoding it

const encode = Buffer.from(hash, 'base64');

to this

const encode = Buffer.from(hash).toString('base64').toString('utf-8');

Now its perfect and matches the string length and works perfectly.
