试试这些函数，

var JsonToArray = function(json)
{
    var str = JSON.stringify(json, null, 0);
    var ret = new Uint8Array(str.length);
    for (var i = 0; i < str.length; i++) {
        ret[i] = str.charCodeAt(i);
    }
    return ret
};

var binArrayToJson = function(binArray)
{
    var str = "";
    for (var i = 0; i < binArray.length; i++) {
        str += String.fromCharCode(parseInt(binArray[i]));
    }
    return JSON.parse(str)
}

如果你不能使用TextDecoder API，因为它不支持IE:

你可以使用Mozilla开发者网络网站推荐的faststsmallsttextencoderdecoder polyfill; 你也可以在MDN网站上使用此功能:

function utf8ArrayToString(aBytes) { var sView = ""; for (var nPart, nLen = aBytes.length, nIdx = 0; nIdx < nLen; nIdx++) { nPart = aBytes[nIdx]; sView += String.fromCharCode( nPart > 251 && nPart < 254 && nIdx + 5 < nLen ? /* six bytes */ /* (nPart - 252 << 30) may be not so safe in ECMAScript! So...: */ (nPart - 252) * 1073741824 + (aBytes[++nIdx] - 128 << 24) + (aBytes[++nIdx] - 128 << 18) + (aBytes[++nIdx] - 128 << 12) + (aBytes[++nIdx] - 128 << 6) + aBytes[++nIdx] - 128 : nPart > 247 && nPart < 252 && nIdx + 4 < nLen ? /* five bytes */ (nPart - 248 << 24) + (aBytes[++nIdx] - 128 << 18) + (aBytes[++nIdx] - 128 << 12) + (aBytes[++nIdx] - 128 << 6) + aBytes[++nIdx] - 128 : nPart > 239 && nPart < 248 && nIdx + 3 < nLen ? /* four bytes */ (nPart - 240 << 18) + (aBytes[++nIdx] - 128 << 12) + (aBytes[++nIdx] - 128 << 6) + aBytes[++nIdx] - 128 : nPart > 223 && nPart < 240 && nIdx + 2 < nLen ? /* three bytes */ (nPart - 224 << 12) + (aBytes[++nIdx] - 128 << 6) + aBytes[++nIdx] - 128 : nPart > 191 && nPart < 224 && nIdx + 1 < nLen ? /* two bytes */ (nPart - 192 << 6) + aBytes[++nIdx] - 128 : /* nPart < 127 ? */ /* one byte */ nPart ); } return sView; } let str = utf8ArrayToString([50,72,226,130,130,32,43,32,79,226,130,130,32,226,135,140,32,50,72,226,130,130,79]); // Must show 2H₂ + O₂ ⇌ 2H₂O console.log(str);

Uint8Array to String

let str = Buffer.from(key.secretKey).toString('base64');

String到Uint8Array

let uint8arr = new Uint8Array(Buffer.from(data,'base64')); 

做什么@Sudhir说，然后得到一个字符串，逗号分隔的数字列表使用:

for (var i=0; i<unitArr.byteLength; i++) {
            myString += String.fromCharCode(unitArr[i])
        }

这会给你想要的字符串， 如果还相关的话

使用base64作为编码格式效果很好。这就是它是如何实现通过url在Firefox发送传递秘密。您将需要base64-js包。下面是Send源代码中的函数:

const b64 = require("base64-js")

function arrayToB64(array) {
  return b64.fromByteArray(array).replace(/\+/g, "-").replace(/\//g, "_").replace(/=/g, "")
}

function b64ToArray(str) {
  return b64.toByteArray(str + "===".slice((str.length + 3) % 4))
}

var decodedString = decodeURIComponent（escape（String.fromCharCode（...new Uint8Array（err））））; var obj = JSON.parse（decodedString）;
