  •  VisaNet交易直连消息结构
    1.  消息结构说明

VisaNet 直连交易消息遵循 ISO 8583:1993 (Visa Extended Format) 标准,结合 Visa 自定义的报文头(Message Header)、专用私有域(如 Field 63 等)及 VisaNet 路由标识信息。
一条完整的 Visa 交易请求或应答消息通常由以下部分组成:

序号

结构部分

说明

1

Message Header(消息头)

VisaNet 在 ISO8583 报文前增加的专有头部,用于标识报文方向、来源及目标系统。主要字段包括: 

- Destination Station ID(目的站点号) 

- Source Station ID(源站点号) 

- Message Status Indicator(消息状态) 

- Round Trip Control Information (用于匹配请求应答) 

- Message Format Indicator (MFI) 

- Message Function Code 等

2

MTI(Message Type Identifier)消息类型标识

表示交易报文的类型,例如:

0100 – 授权请求(Authorization Request) 

0110 – 授权应答(Authorization Response) 

0200 – 财务请求(Financial Request) 

0210 – 财务应答(Financial Response) 

0420 – 冲正通知(Reversal Advice) 

0430 – 冲正应答(Reversal Response) 等

3

Primary Bitmap & Secondary Bitmap & ThirdBitmap

位图用于标识报文中实际存在的 Data Element 字段。每个 bit 对应 1 个 ISO 字段,当 bit 值为 1 时表示该字段存在。

4

Data Elements (ISO Fields)

报文主体数据,包含 DE 1 至 DE 128 等标准域,常见字段包括: 

- DE 2 主账号(PAN) 

- DE 3 处理码(Processing Code) 

- DE 4 交易金额(Amount, Transaction) 

- DE 7 传输日期时间(Transmission Date & Time) 

- DE 11 系统跟踪号(STAN) 

- DE 37 检索参考号(RRN) 

- DE 41 终端标识号(TID) 

- DE 43 商户名称与地址 - DE 49 交易货币代码(Currency Code) 等

5

Private Data Fields (Visa Private Use)

Visa 专用私有域,包括但不限于: 

- DE 62 Visa Private Data(可包含各类控制数据) 

- DE 63 VIP Private Use Field(用于 VisaNet 内部标识及控制信息) 

- DE 126 Private Data(根据产品/业务类型定义) 等

补充说明:

  1. VisaNet 采用 Big-Endian 编码,字符串为 EBCDIC及自定义字段编码、解码格式;
  2. 消息头根据请求、响应其头的长度及字段类型不同,具体请参考Visa相关文档;
  3. VisaNet 消息通过 TCP/IP 或 TLS 直连方式传输,采用 VisaNet Session Control 协议(VSCP)进行会话管理;
  4. 在开发与调试时,应优先确认 Header、MTI 与 Bitmap 的正确性,以确保 Visa 可识别报文类型与字段结构;

+------------------------+
| Reject Message Header  |  <-- VisaNet 加的(Header field 1 length must be 26 or higher)
+------------------------+
| Original Msg Header    |  <-- 原始发过来的报文头
+------------------------+
| Original Msg Data      |  <-- 原始发过来的数据部分(如 Bitmap + Data Elements)
+------------------------+

3.1.1 消息结构概述

VISA的授权类消息采用ISO 8583标准格式,主要由以下部分组成:

  1. 消息类型标识符(MTI):指示消息的类型,如0100表示授权请求。
  2. 位图(Bitmap):指示后续数据字段的存在与否。
  3. 数据字段(Data Elements):包含具体的交易信息,如卡号、金额、交易时间等。

3.1.2 主要消息类型

常见的ISO 8583消息类型包括:

  1. 0100:授权请求(Authorization Request)
  2. 0110:授权请求响应(Authorization Request Response)
  3. 0400:授权撤销请求(Authorization Reversal Request)
  4. 0420:授权撤销请求响应(Authorization Reversal Request Response)

3.1.3 消息构成

Visa的报文主要由两个主要部分组成:报文头(12或14个字段)、报文体;其中请求参数中作为标准报文组装,但响应参数分为两种:正常响应、异常响应;

正常响应:12个字段的请求头、报文体(MTI、Bitmap、Fields);

异常响应:14个字段的请求头(含错误码)、12个字段的请求头(原始请求头)、报文体(MTI、Bitmap、Fields);

其中无论是Message Header还是Message Type Indicator (MTI)、BitMap、Fields都是按照固定格式组装的报文数据;组装完成的数据在上送Visa VTS或者VCMS交易模拟器之前必须按照对应数据长度配置格式(2 或 4个byte)填充数据长度位标识;

3.2 卡组基础业务阐述

卡组织介绍:

国际信用卡组织,国际上六大信用卡组织分别是VISA、MasterCard(万事达卡)、American Express(美国运通)、UnionPay(银联)、JCB和Diners Club。除银联和JCB外,其余四大信用卡均起源于美国。

6大卡组全称:Visa Card、Master Card、Japan Credit Bureau、Diners Club、America Express、Union Pay;

卡组织定义:

全称银行卡转接清算机构(又称信用卡组织/银行卡组织),由成员组成的国际性或区域性支付卡组织,授权成员发卡,受理商户的卡交易,拥有并经营自己的国际区域处理网络。

卡组职责:

1、卡组织负责建设和运营全球或区域统一的支付卡信息交换网络,负责支付卡交易的信息转换和资金清算, 制定并推行支付卡跨行交易业务规范和技术标准。

2、卡组织成立后要做的第一件事就是吸收会员或成员并建设和运营一个庞大的网络(如visa的visanet,中国银联的跨行交易清算系统CUPS等等),这个网络主要负责银行卡交易的信息交换、资金清算等等很多功能。

 而加入银行卡组织的会员(比如银行)一般也有自己的网络,比如支付网络或交易清算网络等等,当会员加入银行卡组织后,该会员的网络就会与银行卡组织的国际网络进行联网,与银行卡组织进行全球的信息交换、交易处理、资金清算等业务。

所以,一个银行卡组织的会员越多,会员遍布范围越广,那么这个银行卡组织的国际性和全球性就越强,服务就更加便利,总之,银行卡组织的国际网络和其会员的自有网络进行联网,共同构成遍布全世界的金融交易网络。

卡组织银行卡组织本身并不发卡,而是由加入银行卡组织的金融类机构会员(主要是银行)来发行各种卡片,并且会提示其会员机构们开发新的支付产品和技术。持卡人的相关关系也由各金融机构自己负责管理。

卡组交易流程:

OPGS系统和卡组交易过程中,其交易核心使用TCP长连接方式进行数据交互,报文以8583格式进行交互;报文提需要根据不同卡组相关规范进行拆包解包;其OPGS提供交易业务流程如下所示:

  1. 商户发起授权请求进入OPGS对外API中:http-json;
  2. OPGS处理参数,完成基础参数封包,并通过TCP长连接上送至卡组:TCP-8583;
  3. 卡组完成交易,并通过TCP长连接返回给OPGS;OPGS通过拆包完成数据解析,并同步更新交易信息;
  4. OPGS根据交易结果封装为JSON报文返回给商户/调用方:http-json;

TCP报文编写规范:

  1. 每一个卡组一种独立处理映射AOP处理器;
  2. 卡组规范(数据类型、编码、长度)使用统一枚举;
  3. 报文拆包粘包每个卡组均使用统一规范;

卡组交易流程:

OPGS系统和卡组交易过程中,其交易核心使用TCP长连接方式进行数据交互,报文以8583格式进行交互;报文提需要根据不同卡组相关规范进行拆包解包;其OPGS提供交易业务流程如下所示:

  1. 商户发起授权请求进入OPGS对外API中:http-json;
  2. OPGS处理参数,完成基础参数封包,并通过TCP长连接上送至卡组:TCP-8583;
  3. 卡组完成交易,并通过TCP长连接返回给OPGS;OPGS通过拆包完成数据解析,并同步更新交易信息;
  4. OPGS根据交易结果封装为JSON报文返回给商户/调用方:http-json;

TCP报文编写规范:

  1. 每一个卡组一种独立处理映射AOP处理器;
  2. 卡组规范(数据类型、编码、长度)使用统一枚举;
  3. 报文拆包粘包每个卡组均使用统一规范;
