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)
}

我正在使用这个Typescript代码片段:

function UInt8ArrayToString(uInt8Array: Uint8Array): string
{
    var s: string = "[";
    for(var i: number = 0; i < uInt8Array.byteLength; i++)
    {
        if( i > 0 )
            s += ", ";
        s += uInt8Array[i];
    }
    s += "]";
    return s;
}

如果需要JavaScript版本，则删除类型注释。 希望这能有所帮助!

对于ES6和UTF8字符串

decodeURIComponent(escape(String.fromCharCode(...uint8arrData)))

到目前为止，对我来说最简单的方法是:

//1. Create or fetch the Uint8Array to use in the example
const bufferArray = new Uint8Array([10, 10, 10])

//2. Turn the Uint8Array into a regular array
const array = Array.from(bufferArray);

//3. Stringify it (option A)
JSON.stringify(array);


//3. Stringify it (option B: uses @serdarsenay code snippet to decode each item in array)
let binArrayToString = function(binArray) {
    let str = "";
    for (let i = 0; i < binArray.length; i++) {        
        str += String.fromCharCode(parseInt(binArray[i]));
    }
    return str;
}

binArrayToString(array);

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)
}

在一个Chrome示例应用程序中可以找到，尽管这意味着对于更大的数据块，您可以接受异步转换。

/**
 * Converts an array buffer to a string
 *
 * @private
 * @param {ArrayBuffer} buf The buffer to convert
 * @param {Function} callback The function to call when conversion is complete
 */
function _arrayBufferToString(buf, callback) {
  var bb = new Blob([new Uint8Array(buf)]);
  var f = new FileReader();
  f.onload = function(e) {
    callback(e.target.result);
  };
  f.readAsText(bb);
}
