###工商银行支付API Sdk封装

本类库为开发对接工行扫码付，根据工行原商户文档sdkDemo及自己修改之后的类库，原文档地址

原demo无命名空间支持，且不符合个人使用习惯，本类库对原代码进行修改符合个人使用习惯和composer支持，如遇到使用困难或无法使用可参考下载官方demo

调用二维码被扫支付的大致代码如下：

<?php

if(file_exists($privateKeyPath)) {
    $privateKey = file_get_contents($privateKeyPath);
}else{
    echo "读取私钥失败";
    die;
}
//请注意网关公钥需符合公钥格式
$icbcPublicKeyPath = 'API_GATEWAY_REAL.pub';

if(file_exists($icbcPublicKeyPath)) {
    $icbcPublicKey = file_get_contents($icbcPublicKeyPath);
}else{
    echo "读取网关公钥失败";
    die;
}
//以下构造函数第1个参数为appid，第2个参数为RSA密钥对中私钥，第6个参数为API平台网关公钥
