>当前build,CI状态:

first step:

npm i tlv-nodejs

test case:

``
var tlv = require('tlv-nodejs');
var reportData = new Buffer([0xAA, 0x27, 0xDA, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x02, 0xCA, 0xB6, 0x01, 0x01, 0xA0, 0x01, 0x01, 0xB0, 0x02, 0x12, 0x34, 0xB1, 0x02, 0x12, 0x34, 0xB5, 0x03, 0x05, 0x95, 0x1, 0xB4, 0x07, 0x31, 0x67, 0x2E, 0x4D, 0x69, 0x6D, 0x41, 0x2a], 'hex');

var command = {
ca_appointment_wash: 1,
ca_pay_result: 1,
ca_balance: 133.3,
ca_fee_price: 133.3,
ca_mode_price: '5_4.05',
ca_pwd: '1g.MimA'
};

var hex = tlv.buf2string(tlv.json2hex4tlv(command, tlvspec.commandSpec, '0xDB')).toLowerCase();
console.log(hex);
var json= tlv.hex2json4tlv(reportData, tlvspec.statusSpec('04CA'));
console.log(json);

tlv decode for node.js

console.log 如下 :
