MagicArray:像php一样,让Go业务代码不再卷!

卷!一个字形容了当今码农行业的现状。一层一层的代码结构,一个一个dto,entity,vo,req,resp。这些对象越来越多,让码农们非常劳于奔命,加一个字段,改一个字段,影响面有多少。代码量也越来越大。有可能一个代码,要建10多个数据对象。这虽然有点夸张,但体现了行业的乱象。

我是曾经写php代码的研发,由于php的并发能力的不足,和编译检错能力不足,导致行业用php越来越少了。但是不得不说,在php的时代,跟本不需要这么多对象,因为有一个强大的array,包罗万象。难道我们go、java都不能也通过这种方式实现吗?

 

 

Allright,  由此,MagicArray就诞生了,不用关心类型,不用关心空指针,不用创建哪么多数据对象,轻松数据转换。废话不多说,上代码:

go get github.com/lingdor/magicarray@v0.0.5

DTO替代方式:

package main

import (
    "encoding/json"
    "fmt"
    arr "github.com/lingdor/magicarray"
    "time"
)

type UserDTO struct {
    Id   int `json:"userid"`
    Name string
}

type ScoreDTO struct {
    Score     int
    ScoreTime time.Time
}

type AreaDto struct {
    CityId int
    City   string
}

func dtosCommand() {

    user := UserDTO{
        Id:   1,
        Name: "bobby",
    }
    score := ScoreDTO{
        Score:     66,
        ScoreTime: time.Now(),
    }
    area := AreaDto{
        CityId: 10000,
        City:   "beij",
    }

    mix, _ := arr.Merge(arr.ValueofStruct(user), score, area)
    mix = arr.Pick(mix, "Id", "City", "Score")
    if bs, err := json.Marshal(mix); err == nil {
        fmt.Println(string(bs))
    } else {
        panic(err)
    }

}

 

输出

{"userid":1,"City":"newyork","Score":66}

数据变换

package main

import (
    "encoding/json"
    "fmt"
    arr "github.com/lingdor/magicarray"
)

type ColumnUserEntity struct {
    Id       int `json:"uid"`
    UserName string
    IsMale   bool
}

func columnCommand() {

    users := []ColumnUserEntity{
        {
            Id:       1,
            UserName: "Bobby",
            IsMale:   true,
        },
        {
            Id:       2,
            UserName: "Lily",
            IsMale:   false,
        },
    }

    usersArr := arr.ValueOfSlice(users)
    usersArr = arr.WashColumn(usersArr, arr.WashTagRuleJsonInitialLower())
    if bs, err := json.Marshal(usersArr); err == nil {
        fmt.Println(string(bs))
    } else {
        panic(err)
    }

    usersArr = arr.Column(usersArr, "UserName")
    if bs, err := json.Marshal(usersArr); err == nil {
        fmt.Println(string(bs))
    } else {
        panic(err)
    }

}

输出

["Bobby","Lily"]

tag操作

package main

import (
    "encoding/json"
    "fmt"
    arr "github.com/lingdor/magicarray"
)

type UserEntity struct {
    Id       int `json:"uid"`
    UserName string
    IsMale   bool
}

func tagCommand() {

    users := UserEntity{
        Id:       1,
        UserName: "Bobby",
        IsMale:   true,
    }

    userArr := arr.ValueofStruct(users)
    userArr = arr.SetTag(userArr, "Id", "json", "UserId")
    if bs, err := json.Marshal(userArr); err == nil {
        fmt.Println(string(bs))
    } else {
        panic(err)
    }

}

 

输出


{"uid":1,"UserName":"Bobby","IsMale":true,"UserId":1}
