# [工行在线支付接口实战开发流程及源码][Link 1] #

作为刚毕业的我来说，第一次开发在线支付功能,还是工行的，真的是被坑死了，和工行的技术真的是太难沟通了，而且那个技术明显是他们接口问题还死不承认，总是让我细读开发文档，结果我代码什么都没改，他调试接口后可以运行支付了，他无话可说……希望这篇能让一些人少走一些弯路。进入正题：

**一、  前期准备**

1.  支付组件注册（PS:当时工行技术根本没有给我这个组件，被坑了，当时还想骂那个技术一下，签名什么的，难道我随便按照自己的想法签一个也可以？后来终于给我了）

组件注册说明

一、API配置说明：

1.将ICBCEBankUtil.dll和infosecapi.dll两个dll文件拷贝到系统system32目录下(其中，如果是64位系统，则拷贝到SysWOW64目录下)；

2.打开DOS窗口，进入system32目录/SysWOW64目录；

3.运行“regsvr32 ICBCEBankUtil.dll”命令注册控件；

二、函数说明：

1、初始化

init(

BSTR certFN,银行证书文件名

BSTR certFNM,商户证书文件名

BSTR keyFN,私钥文件名

BSTR key私钥保护口令

)

返回值：

\-100:银行证书文件名传递错

\-101:商户证书文件名传递错

\-102:私钥文件名传递错

\-103:私钥保护口令传递错

\-110:打开银行证书文件错

\-111:打开商户证书文件错

\-112:打开私钥文件错

2、签名

signC(

BSTR src,明文字符串

int srcLen,明文长度

)

返回值：

如果成功则返回BASE64编码后的签名串，否则返回空串

如果返回空串，可调用getRC取得错误码

3、获取错误码（只在出错时有效）

getRC

返回值

-100:明文字符串传递错误

-1:明文错误

\-2:私钥错

\-3:私钥解密错

\-4：私钥保护口令错

4、验证签名

verifySignC(

BSTR src,明文字符串

int srcLen,明文字符串长度

BSTR sSrc,签名BASE64编码字符串

int sSrcLen签名BASE64编码字符串长度

)

返回值：

0：成功

\-1：验证失败

\-2：解码失败

\-100:明文字符串传递有误

\-101:签名字符串传递有误

5、获取证书

getCert(

int which证书类型：0银行证书，1商户证书

)

返回值：BASE64编码后的证书

注册好以后将infosecapi.dll引用到项目中。

2.证书引用

然后将public.crt、商户.crt、商户.key 这三个文件放到项目某个文件夹下

**二、      开发阶段**

1.  首先必须细读：《中国工商银行网上银行新B2C在线支付接口说明V1.0.0.11》这个文档（PS:工行人员当时没有给我这个文档，打电话过去问技术，技术让我细读这个文档，根本没有这个文档，还说他发给客户了的，问客户也说没有发过，当时真的是被坑好多，后来网上找到了一个）。
2.  以下是源码：

**三、注意事项**

根据本人被坑死的经历，告诉大家注意以下事项：

1.在支付发送数据时，支付金额应该是以“分”为单位，也就是金额是一个整数。

2.在进行测试的时候，订单提交时间必须和他们服务器时间一致，而他们，工行测试服务器时间是被他们设置了的，根本不是正常时间，最重要的一点是，时间每天都在变化，比如今天是2016年8月22号，明天可能是2016年8月26号之类的，之前他们没有直接诶告诉我，被坑死了。时间不对，支付不了哦。

3.在测试时，支付成功后不会跳转到我们的支付返回地址，这个也必须注意一下，这也是他们测试服务器的原因，本人在这里也是被坑了，这样的话我们也无法更新本地订单支付状态表。

本来很久之前就该写好的了，当时技术经理让我做完这个功能写一篇技术文档给后来人借鉴下的，可惜一直比较懒，现在我敬爱的技术经理都走了，我遇到的第一位温柔可亲的还对我这么好的技术经理居然都走了（PS：是个男的哦），真的很不舍。我多希望我们部门能尽快找到一位新的技术经理，带我飞，至少我才踏入这个社会，很多东西需要学习，有人给我引路，我会少走很多弯路，进步更快一些。
