小程序websocket推送消息Uint8Array/ArrayBuffer

// 小程序中sendSocketMessage是支持ArrayBuffer的，我这个错误原因在于new Uint8Array不是ArrayBuffer，而是他的一个属性值才是arrayBuffer
var init8arr = new Uint8Array([1,0,2,0,1]);
wx.sendSocketMessage({
    data: init8arr.buffer,
    success:function(e){
         console.log(e)
    },
    fail:function(e){
         console.log(e)
    },
    complete:function(e){
         console.log(e)
    }
});

function decodeUTF8(arr) {
    var str = '';
    for (var i = 0; i < arr.length; i++) {
        str += String.fromCharCode(arr[i]);
    }
    return decodeURIComponent(escape(str));
}

console.log(decodeUTF8([230, 177, 137, 229, 173, 151]));
