本文实例讲述了php版交通银行网银支付接口实现方法。分享给大家供大家参考，具体如下：

概述:网银支付接口 和支付宝接口大体上差不多,主要的区别是 交通银行提供的 接口核心的比如,加密等是通过java实现的,所以,要想办法使php和java能正常的通信,为此,官方也提供了两套实现方法,一个是通过 socket 进行通信,另一个方法是通过 java 桥接,下面演示的是 socket方法.

1. 配置运行环境

1.1  安装java,自行到oracle官网下载 java,然后安装,并配置正确的 环境变量.

1.2  把 测试的证书导入到java 虚拟机.

keytool " -import -keystore "java虚拟机放置证书的地址" -storepass changeit -alias test_bocommca -file "证书路径" 完成导入。

例子:keytool" -import -keystore "C:＼Program Files＼Java＼jre1.5＼lib＼security＼cacerts" -storepass changeit -alias test_bocommca -file "C:＼socket＼cert＼test_root.cer"

1.3  修改配置文件(in/B2CMerchantSocket.xml).

采用官方提供的测试 商号进行测试时,无需配置,否则要配置,具体看xml文件说明.

1.4  启动 socket 服务

window:启动  start.bat 及可.

linux:启动  ohup  sh.start,sh&  //使当前脚本脱离终端，并在后台运行。

2. 将网银集成到现有的系统,以mvc的结构进行说明.

2.1  将不变的参数 配置 写入配置文件:

$config["interfaceVersion"] = "1.0.0.0"; #接口版本
$config["tranType"] =0; #交易类别 0:B:C
$config["curType"] = "CNY"; # 交易币种
$config["notifyType"] =1; #0=不通知 1=通知 2=抓取
$config["merURL"] = "/pay/notify";  # 主动通知url
$config["goodsURL"] = "/goods/1.html"; #取货url
$config["jumpSeconds"] =3; #跳转时间
$config["payBatchNo"] = ""; #商户批次号
$config["proxyMerName"] = ""; #代理商家名字
$config["proxyMerType"] = ""; #代理商类型
$config["proxyMerCredentials"]= ""; #代理商家批次号
$config["netType"] = 0; #渠道编号
//以下是 新接口需要的参数
$config["socketUrl"] ="tcp://127.0.0.1:8891"; #socket url
$config["merID"] ="301310063009501"; #商户id 3013100630095012

2.2 Model

2.3 控制器

$this->load->model("Bocom");

支付方法:

$this->arrData =$this->Bocom->pay($this->data);

通知:

$this->arrData =$this->Bocom->notify();
