1.背景：

最近在写项目，在项目中有一个需求是获取用户的地理位置，一开始是打算让前端使用JSON包的形式去实现，但是考虑到后期可能需要对省市的数据做一些修改和控制操作，所以改为后端实现，并向后台暴露一套接口，方便对城市信息进行增删改查的管理。由于项目中仅仅需要省市二级数据，所以本篇博客就以省市二级数据为例，带领读者朋友们从数据的收集、清洗到存储数据库。

2.数据说明：

数据来源： 中国省市区数据: 省市区联动数据源 (gitee.com)

这个仓库里面也有sql数据，导入数据库即可使用。但是由于项目需求的问题，如果直接导入的话，还需要添加其他的字段，并对里面的值进行一些填充比较麻烦，所以我就选择使用json作为原始数据。大致流程为将JSON字符串反序列化为结构体，在结构体中对一些业务的数据进行填充，直接将数据导入到数据库中。

3.解析json串

二级省市数据：选择带结构的json串，这样我们才可以根据字段进行解析。

在解析数据之前，我们需要分析一下数据的结构，可以看出来数据是两层,我们可以定义如下的结构体:

type District struct {Code     string        `json:"code"`Name     string        `json:"name"`Children []SubDistrict `json:"children"`
}type SubDistrict struct {Code     string        `json:"code"`Name     string        `json:"name"`
}

 我们可以根据业务的需要对结构体进行一些修改，本次项目，根据项目的需求我们需要对一些字段进行增加、修改的操作，项目中的结构体如下：

type District struct {gorm.ModelCode     string        `json:"code" gorm:"-"`Value    string        `json:"name" gorm:"column:value"`Text     string        `json:"text" gorm:"column:text"`Disabled int           `json:"disabled" gorm:"column:disabled"`Pid      int           `json:"pid" gorm:"column:pid"`Children []SubDistrict `json:"children" gorm:"-"`
}type SubDistrict struct {gorm.ModelCode     string `json:"code" gorm:"-"`Value    string `json:"name" gorm:"column:value"`Text     string `json:"text" gorm:"column:text"`Disabled int    `json:"disabled" gorm:"column:disabled"`Pid      int    `json:"pid" gorm:"column:pid"`
}

直接注意的是，在我们的District结构体中的Value字段，我们可以发现json标签中是name,gorm中是value,这就是结构体中tag标签的神奇之处。通过tag标签我们可以非常方便地对程序中的数据进行转换。

关于Tag的作用：

Go语言的反射特性可以动态地给结构体成员赋值，正是因为有Tag，在赋值前可以使用Tag来决定赋值动作。比如说官方的encoding/json包，可以将一个JSON数据“Unmarshal”进一个结构体，此过程中就使用了Tag。该包定义了一些Tag规则，只要参考该规则设置Tag就可以将不同的JSON数据转换成结构体。

综上，对于struct而言，Tag仅仅是一个普通的字符串，而其他库定义了字符串匹配规则并据此演绎出了丰富的应用。提高结构体数据进行数据交互时的灵活性，而不需要重写结构体，进行再次赋值。

具体的转码代码如下：完成json向结构体的转换，并重新组织数据插入数据库。
