Uint8Array数组转换为字符串可以通过多种方法实现。以下是几种常用的方法,每种方法都附有代码示例: 方法一:使用TextDecoder TextDecoder是一个内置对象,它可以将ArrayBuffer或TypedArray(如Uint8Array)解码为字符串。这是推荐的方法,因为它能够正确处理多字节字符编码(如UTF-8)。 javascrip
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 ...
function arrayBufferToString(arr){ if(typeof arr === 'string') { return arr; } var dataview=new DataView(arr.data); var ints=new Uint8Array(arr.data.byteLength); for(var i=0;i<ints.length;i++){ ints[i]=dataview.getUint8(i); } arr=ints; var str = '', _arr = arr; ...
}//It's an array; check it is a valid representation of a byteif(Array.isArray(arg)) {if(!checkInts(arg)) {thrownewError('Array contains invalid value: ' +arg); }returnnewUint8Array(arg); }//Something else, but behaves like an array (maybe a Buffer? Arguments?)if(checkInt(arg...
utf8Bytes`现在是一个包含UTF-8编码字节的Uint8Array。 使用encodeURIComponent和unescape(兼容性较好) 代码语言:txt 复制 function toUTF8(str) { return unescape(encodeURIComponent(str)); } const utf8Str = toUTF8("你好,世界!"); 注意:这种方法返回的是一个UTF-8编码的字符串,但它可能包含百分号编码...
}//Something else, but behaves like an array (maybe a Buffer? Arguments?)if(checkInt(arg.length) &&checkInts(arg)) {returnnewUint8Array(arg); }thrownewError('unsupported array-like object'); }return{ toBytes: toBytes, fromBytes: utf8ByteToUnicodeStr ...
file(name, data [,options]) :创建zip文件,可以放入多个文件,支持多种文件格式String/ArrayBuffer/Uint8Array/Buffer/Blob/Promise/Nodejs stream, Content ofoptions: generateAsync(options[, onUpdate]): 生成一个完整的zip的文件在当前文件目录 返回一个promise ...
You can pass a string, Uint8Array in UTF-8, VFile, or anything that can be given to new VFile.import {compile} from '@mdx-js/mdx' import {VFile} from 'vfile' await compile(':)') await compile(Buffer.from(':-)')) await compile({path: 'path/to/file.mdx', value: '🥳'}...
utf8.encode: Convert an UTF-8 string into an array of bytes (Uint8Array) utf8.decode: Convert an array of bytes into an UTF-8 string Examples: import{utf8}from'@47ng/codec'constuint8Array=utf8.encode('Hello, World!')// Uint8Array [72, 101, 108, 108, 111, 44, 32, 87, 111...
bytes[i] = chars[i]; } return buffer; } static toString(bytes) { return fromUTF8(bytes); }} 使用的方式和 Node.js 一样。 代码语言:javascript 代码运行次数:0 运行 AI代码解释 Buffer.from("你好") 字符串通过 Buffer 类实现,Buffer 封装了 ArrayBuffer 和 Uint8Array,不过更重要的是实现了 UTF...
