iso8583-es

iso8583-es

A pure, high-performance library with ES6 and typescript, used to encode and decode the ISO8583 protocol

Note: Please use latest version

Usage

npm i --save iso8583-es

编码

import i8es from 'iso8583-es'
const {
  HEX, FieldDefinition, ISOBody, ISOField, ISOInputStream, ISOOutputStream
} = i8es

const fields = ISOField.makeFields(FieldDefinition, true); // 全局初始化一次

const body = new ISOBody(fields);
body.setType("0800"); // 签到
body.setField(11, "000456"); // 流水号
body.setField(41, "12345678"); // 终端编号
body.setField(42, "123456789012345"); // 商户编号
body.setField(60, "00" + "123456" + "003"); // 消息类型码00+批次号+双倍长密钥算法
body.setField(63, "03"); // 操作员号
const ios = new ISOOutputStream();
body.appendTo(ios);
console.log("编码结果")
console.log(HEX.byte2Hex(ios.toByteArray()))
console.log(body.toString())
