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
- 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
- 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）。
- 以下是源码：

然而，比较重要的一个还有支付查询页面，防止比如支付成功了，但由于网络异常等原因没有返回支付成功数据等情况下使用。

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。
