Use regular expressions in golang to verify whether the input is a legal property fee account number

Property fee is a fee that community owners must pay every month, and the property fee account number is a unique identifier owned by each owner, similar to a bank card number. When paying property fees, entering an incorrect account number may result in payment failure, causing trouble and losses to the owner and property company. In order to ensure smooth payment, property companies usually require owners to meet certain format requirements when filling in their account numbers. This article will introduce how to use regular expressions in golang to verify whether the input is a legal property fee account number.

First of all, we need to understand the format requirements of the property fee account number. Usually, a legal property fee account number should meet the following conditions:

1. consists of numbers
2. The number is 16 digits

Next, we You need to use the regular expression library that comes with golang to verify whether the input is a legal property fee account number. The sample code is as follows:

import (
    "fmt"
    "regexp"
)

func main() {
    // 定义正则表达式
    r, _ := regexp.Compile("^[0-9]{16}$")

    // 测试合法的账户号
    accountNumber := "1234567890123456"
    if r.MatchString(accountNumber) {
        fmt.Println("合法的物业费账户号")
    } else {
        fmt.Println("非法的物业费账户号")
    }

    // 测试非法的账户号
    accountNumber = "123456789012345"
    if r.MatchString(accountNumber) {
        fmt.Println("合法的物业费账户号")
    } else {
        fmt.Println("非法的物业费账户号")
    }
}

In the above code, we define a regular expression r to verify whether the property fee account number is a 16-digit number. Specifically, in the regular expression:

• ^ represents the beginning of the string
• [0-9] represents the numeric character
• {16} represents 16 occurrences
• $ represents the end of the string

If the property fee account number meets the above requirements, return true, otherwise return false.

Through the above example code, we have implemented the use of regular expressions in golang to verify whether the input is a legal property fee account number. This approach ensures that account numbers are in the correct format and avoids the risk of payment failures and data errors, thereby increasing owner and property company satisfaction.
