把string转成Uint8Array,代码如下: 深色代码主题 复制 public static stringToUint8Array(str: string): Uint8Array { const utf8 = unescape(encodeURIComponent(str)); const arr = new Uint8Array(utf8.length); for (let i = 0; i < utf8.length; i++) { arr[i] = utf8.charCodeAt(i); }...

I see that undici is mostly using Buffer.from(name).toString('utf8'). This crosses the JS-C++ boundary 2 times. 1 for initializing, and 1 for toString. I recommend implementing a function like this: Buffer.asString(name, encoding) which ...
TextDecoder是一个内置的JavaScript API,用于解码Uint8Array为字符串。它支持多种字符编码,例如UTF-8、UTF-16等。 使用String.fromCharCode()方法: 代码语言:txt 复制 const uint8Array = new Uint8Array([72, 101, 108, 108, 111]); const string = String.fromCharCode.apply(null, uint8Array); console....
