golang implementation 8583

In the financial industry, the 8583 protocol is widely used to transmit various financial information data such as magnetic stripe cards, IC cards, and mobile payment. Due to the importance of transmitting data, the implementation of the 8583 protocol is correspondingly complex and requires a high level of technology and experience and knowledge in related industries. This article will introduce how to use Golang language to implement the 8583 protocol.

1. What is the 8583 protocol?

8583 protocol is a financial transaction message format standard that defines the message format and communication process during financial transactions. This protocol is commonly used in financial systems such as ATM machines, POS terminals, payment gateways and banking systems.

The protocol was developed and published by ISO (International Organization for Standardization). The ISO8583 standard defines message formats and communication protocols commonly used in financial transactions. This protocol has a very wide range of applications, especially in financial fields such as banking, securities, payments and credit cards.

2. Introduction to Golang language

Golang, also known as Go, is a compiled, concurrent, statically typed language launched by Google. The design goal of Golang is to provide a simple and efficient programming language to facilitate the development of parallel computer programs. It has strong advantages in compilation speed, code execution speed, etc. More and more companies and developers are beginning to use this language for software development.

3. Golang implements the 8583 protocol

Due to the complexity of the 8583 protocol, using the Golang language to implement it requires relevant technical experience and knowledge. In Golang, you can use struct (structure) to define the structure of 8583 protocol data.

First, we need to define a structure to represent the message header data of the 8583 protocol, that is, message type, bit field value and bitmap. The definition of the structure is as follows:

type Iso8583Header struct {

MsgType    string
BitMap     []byte
BitMapSize int
BitValue   []string

}

Next, we need to define a structure to represent each data field of the 8583 protocol Format. In this case, we can represent the rules and format of each domain by defining a 256-base map. The advantage of this approach is that it can easily represent various possible data fields and field values. The definition of the structure is as follows:

type Iso8583Field struct {

IsoField     int
IsoLength    int
IsoType      string
IsoAlignment int
IsoPad       byte

}

Finally, we need to define a structure to represent the structure of the entire message body. When defining the message body structure, you need to pay attention to the value of each data field and the bitmap representing the field. The definition of the message body structure is as follows:

type Iso8583 struct {

IsoHeader     *Iso8583Header
IsoFields     map[int]*Iso8583Field
IsoData       []byte
IsoFieldCount int
IsoLength     int

}

After implementing the data structure of the 8583 protocol, we need to parse and format it . In this way, the data of the 8583 protocol can be converted into a readable format, and the data to be sent can also be encoded.

4. Summary

Using Golang language to implement the 8583 protocol can greatly simplify the process of financial data exchange, while improving work efficiency and data security. Although this work requires relevant technical experience and knowledge, using Golang to implement the 8583 protocol can greatly improve the reliability of the transaction process and reduce the difficulty and complexity of the developer's work.
