JSON-to-GO：将JSON转换成Go结构体定义 【纯GOLANG实现】

灵感来自json-to-go

用法：

// 解析json元信息
meta := Parse(json)
// 根据元信息渲染输出结构体定义
// inline:true/false;结构体内联/分离输出
structDef := GenerateStruct(meta, inline)

安装：

go install github.com/AuroraV/json-to-go/cmd/g2j@v0.1.2

j2g -s '{"a":123, "b":{"c":1.23, "d":["9", "8"]}}' -f true --inline true 

Features:

• json转golang结构体定义输出
• 输出模式可选:内联或分离
• CLI交互式生成结构体定义文件
• 内置简单web页，支持在线编辑
• 更多JSON生成代码的探索
• 支持对JSON流进行业务含义定义，类似字典赋能业务
• ...

JSON结构是业内常用的传输语言； 若您有更多JSON可视化想法或对此项目有疑问，欢迎积极参与提ISSUE，您将获得积极的响应。

	structDef := j2g.GenerateStruct(meta, true)
	structDef = j2g.GenerateStruct(meta, false)
	fmt.Println(strings.Join(structDef, "\n----------------------------------------\n"))
	// output:
	/*
		1. output [inline = true] :
		type AutoGenerated []struct {
			InputIndex int64 `json:"input_index"`
			Components []struct {
				PrimaryNumber string `json:"primary_number,omitempty"`
				A float64 `json:"a"`
				B float64 `json:"b,omitempty"`
			} `json:"components"`
		}

		2. output [inline = false] :
		type AutoGenerated []struct {
				InputIndex int64 `json:"input_index"`
				Components []Components `json:"components"`
		}
		----------------------------------------
		type Components struct {
				PrimaryNumber string `json:"primary_number,omitempty"`
				A float64 `json:"a"`
				B float64 `json:"b,omitempty"`
