计划

将 validate_schema、output_schema 改成 key:value 格式(类似go tag)，提升可阅读性和维护效率 出参案例：

{"$schema":"http://json-schema.org/draft-07/schema#","$id":"execAPIXyxzBlacklistInfoPaginate","properties":{"items":{"type":"array","items":{"type":"object","properties":{"id":{"type":"string","src":"PaginateOut.#.Fid"},"openId":{"type":"string","src":"PaginateOut.#.Fopen_id"},"type":{"type":"string","src":"PaginateOut.#.Fopen_id_type"},"status":{"type":"string","src":"PaginateOut.#.Fstatus"}},"required":["id","openId","type","status"]}},"pageInfo":{"type":"object","properties":{"pageIndex":{"type":"string","src":"input.pageIndex"},"pageSize":{"type":"string","src":"input.pageSize"},"total":{"type":"string","src":"PaginateTotalOut"}},"required":["pageIndex","pageSize","total"]}},"type":"object","required":["items","pageInfo"]}

转换为：

fullname:items[].id,src:PaginateOut.#.Fid,type:string,required:true
fullname:items[].openId,src:PaginateOut.#.Fopen_id,type:string,required:true
fullname:items[].type,src:PaginateOut.#.Fopen_id_type,type:string,required:true
fullname:items[].status,src:PaginateOut.#.Fstatus,type:string,required:true
fullname:pageInfo.pageIndex,src:input.pageIndex,type:string,required:true
fullname:pageInfo.pageSize,src:input.pageSize,type:string,required:true
fullname:pageInfo.total,src:PaginateTotalOut,type:string,required:true

入参案例：

{"$schema":"http://json-schema.org/draft-07/schema#","$id":"execAPIXyxzBlacklistInfoInsert","properties":{"config":{"type":"object","properties":{"openId":{"type":"string","format":"DBValidate"},"type":{"type":"string","format":"number","enum":["1","2"]},"status":{"type":"string","format":"number","enum":["0","1"]}},"required":["openId","type","status"]}},"type":"object"}

转换为：

fullname:config.openId,dst:FopenID,format:DBValidate,type:string,required:true
fullname:config.type,dst:FopenIDType,enum:["1","2"],type:string,required:true
fullname:config.status,dst:Fstatus,enum:["0","1"],type:string,required:true

分页入参案例:

{"$schema":"http://json-schema.org/draft-07/schema#","$id":"execAPIInquiryScreenIdentifyPaginate","properties":{"pageSize":{"type":"string","format":"number"},"pageIndex":{"type":"string","format":"number"}},"type":"object","required":["pageSize","pageIndex"]}

转换为:

fullname:pageSize,dst:limit,format:number,type:string,required:true
fullname:pageIndex,dst:Offset,format:number,type:string,required:true,tpl:{{setValue . "Offset" (mul  (getValue .  "input.pageIndex")   (getValue . "input.pageSize"))}}

dst、tpl 字段会提炼出，动态生成 template内容 通过这种转换后，更易于书写和阅读，和计划中的文档格式更相似，同时dst、tpl等字段定义优化了值转换的管理为自动校验提供可行的机制，后续api 的 exec 字段可能被弃用

有偿功能实现,价格500左右, 概念:把

fullname:xxx,type:xxx,required:true ...
fullname:xxx,type:xxx,required:true ...

的格式称为jsonschema 行列式 一行代表一个jsonschema 元素的描述,其格式为key:value,... 其中key包含fullname、src、dst tpl 4个特殊值,其余的为标准的jsonschema 的属性(如 type,required、enum 等关键词) 每对key:value 之间使用英文","分割.顺序无要求,除了fullname、type 属性必须之外,其它属性可有可无,特殊属性描述: fullname 必须存在,由[a-zA-z_]以及特殊字符串.和[]组成.其中"."代表json对象,"[]"代表数组 如"fullname:userList[].name" 代表 userList是数组格式,userList数组元素为对象,数组元素对象有个name属性 src、dst 两个属性无特殊意义,仅仅是给标准jsonschema增加的自定义属性 需要实现的功能: 标准jsonschema和jsonschema 行列式 互转

案例1: jsonschema:

{"$schema":"http://json-schema.org/draft-07/schema#","properties":{"config":{"type":"object","properties":{"openId":{"type":"string","format":"DBValidate"},"type":{"type":"string","format":"number","enum":["1","2"]},"status":{"type":"string","format":"number","enum":["0","1"]}},"required":["openId","type","status"]}},"type":"object"}

对应 jsonschema 行列式

fullname:config.openId,dst:FopenID,format:DBValidate,type:string,required:true
fullname:config.type,dst:FopenIDType,enum:["1","2"],type:string,required:true
fullname:config.status,dst:Fstatus,enum:["0","1"],type:string,required:true

案例2： jsonschema 行列式

fullname:config.openId,dst:FopenID,format:DBValidate,type:string,required:true
fullname:config.type,dst:FopenIDType,enum:["1","2"],type:string,required:true
fullname:config.status,dst:Fstatus,enum:["0","1"],type:string,required:true

jsonschema格式

{"$schema":"http://json-schema.org/draft-07/schema#","properties":{"config":{"type":"object","properties":{"openId":{"type":"string","format":"DBValidate"},"type":{"type":"string","format":"number","enum":["1","2"]},"status":{"type":"string","format":"number","enum":["0","1"]}},"required":["openId","type","status"]}},"type":"object"}

Documentation

Overview

Package jsonschema uses reflection to generate JSON Schemas from Go types [1].

If json tags are present on struct fields, they will be used to infer property names and if a property is required (omitempty is present).

Functions

func Addslashes added in v0.0.12 

func Addslashes(str string) string

func BaseName added in v0.0.21 

func BaseName(fullname string) (baseName string)

BaseName 获取最后.后的文本

func ExtractGoComments 

func ExtractGoComments(base, path string, commentMap map[string]string) error

ExtractGoComments will read all the go files contained in the provided path, including sub-directories, in order to generate a dictionary of comments associated with Types and Fields. The results will be added to the `commentsMap` provided in the parameters and expected to be used for Schema "description" fields.

The `go/parser` library is used to extract all the comments and unfortunately doesn't have a built-in way to determine the fully qualified name of a package. The `base` paremeter, the URL used to import that package, is thus required to be able to match reflected types.

When parsing type comments, we use the `go/doc`'s Synopsis method to extract the first phrase only. Field comments, which tend to be much shorter, will include everything.

A Reflector reflects values into a Schema.

func (*Reflector) AddGoComments 

func (r *Reflector) AddGoComments(base, path string) error

AddGoComments will update the reflectors comment map with all the comments found in the provided source directories. See the #ExtractGoComments method for more details.

func (*Reflector) Reflect 

func (r *Reflector) Reflect(v interface{}) *Schema

Reflect reflects to Schema from a value.

func (*Reflector) ReflectFromType 

func (r *Reflector) ReflectFromType(t reflect.Type) *Schema

func (*Reflector) SetBaseSchemaID 

func (r *Reflector) SetBaseSchemaID(id string)

SetBaseSchemaID is a helper use to be able to set the reflectors base schema ID from a string as opposed to then ID instance.

func Reflect 

func Reflect(v interface{}) *Schema

Reflect reflects to Schema from a value using the default Reflector

Example 
package main

import (
	"encoding/json"
	"fmt"
	"time"

	jsonschema "github.com/suifengpiao14/jsonschemaline"
)

type SampleUser struct {
	ID          int                    `json:"id"`
	Name        string                 `json:"name" jsonschema:"title=the name,description=The name of a friend,example=joe,example=lucy,default=alex"`
	Friends     []int                  `json:"friends,omitempty" jsonschema_description:"The list of IDs, omitted when empty"`
	Tags        map[string]interface{} `json:"tags,omitempty" jsonschema_extras:"a=b,foo=bar,foo=bar1"`
	BirthDate   time.Time              `json:"birth_date,omitempty" jsonschema:"oneof_required=date"`
	YearOfBirth string                 `json:"year_of_birth,omitempty" jsonschema:"oneof_required=year"`
	Metadata    interface{}            `json:"metadata,omitempty" jsonschema:"oneof_type=string;array"`
	FavColor    string                 `json:"fav_color,omitempty" jsonschema:"enum=red,enum=green,enum=blue"`
}

func main() {
	s := jsonschema.Reflect(&SampleUser{})
	data, _ := json.MarshalIndent(s, "", "  ")
	fmt.Println(string(data))
}
