How to use regular expressions in golang to verify whether the input is a legal insured person category

In web application development, we often need to verify the data entered by the user to ensure the integrity and correctness of the data. Among them, regular expressions are a very common verification tool that can effectively verify whether the data format is correct.

In this article, we will explore how to use regular expressions in Golang to verify whether the input is a legal insured person category.

What is the category of insured persons?

In the social security system, the categories of insured persons refer to the different groups of insured persons in social insurance, provident fund and other related systems, including but not limited to workers, farmers, urban and rural residents, retirees, etc. wait.

Regular expression verification

Regular expression is a string matching pattern, which can be used to match specific characters, numbers, symbols, etc. In Golang, we can use the regexp package to perform regular expression verification operations.

First, we need to create a regular expression, and then use the functions in the regexp package to match the data that needs to be verified. Here is a sample code:

package main

import (
    "fmt"
    "regexp"
)

func main() {
    // 创建正则表达式
    pattern := "^(工人|农民|城乡居民|退休人员)$"
    reg := regexp.MustCompile(pattern)

    // 需要验证的数据
    input := "工人"

    // 进行匹配验证操作
    if reg.MatchString(input) {
        fmt.Println("合法")
    } else {
        fmt.Println("不合法")
    }
}

In the above sample code, we first create a regular expression and use the functions in the regexp package to compile it into a usable regular expression object. Then, we pass the data that needs to be verified to the MatchString function for matching verification operations.

In this example, our regular expression only allows matching of the four categories of insured persons: workers, farmers, urban and rural residents, and retirees. If you need to verify other categories, you only need to add the required to the regular expression Just allow matching categories.

Summary

Regular expression is a powerful string matching pattern that can help us perform format verification on data. In Golang, we can use the regexp package to conveniently perform regular expression verification to ensure the integrity and correctness of data. This article focuses on how to use regular expressions to verify whether the input is a legal insured person category, hoping to help readers better understand the application of regular expression verification.
