HexToString(str) {
    if (str.length % 2 != 0) {
        this.$message.error('必须为偶数');
        return '';
    }
    let num;
    let arr = [];
    for (var i = 0; i < str.length; i = i + 2) {
        num = parseInt(str.substr(i, 2), 16);
        arr.push(String.fromCharCode(num));
    }
    return arr.join('');
