本篇文章给大家带来了关于GraphQL的相关知识，其中主要跟大家聊一聊有关基于webman的GraphQL实现，感兴趣的朋友下面一起来看一下吧，希望对大家有帮助。

基于PHP的GraphQL由于加载指令（directive）和解析schema的开销较大，性能不是很理想。webman是常驻内存的，所以GraphQL在webman上的性能表现非常不错。

GrahpQL 是基于YiAdmin的一个模块，用于快速创建GraphQL服务，可以开启多个服务，模块内置了多个指令用于快速开发api接口。

调试接口地址：/graphql-dev/api/服务名称
正式接口地址：/graphql-api/服务名称
后台接口管理可以建立接口名称与Query的映射关系，通过接口名称访问以简化前端输入，curl -X POST -d "{\"variables\": VARIABLES}" -H "Content-type:application/json" "HOST/graphql-api/SERVER_NAME?api=接口名称"
零依商城是基于YiAdmin的uniapp商城系统，Api接口基于GrahpQL进行了重构。

例如有如下 schema

// Type
type Article {
    id: Int
    category_id: Int
    title: String
    description: String
    created_at: Int
    create_time: String @alias(key: "created_at") @date
    status: Int
}

type ArticlePagination {
    pagination: Pagination
    data: [Article]
}

Copy after login

通过模型获取记录，支持模型 scope

// Query
"通过文章ID获取文章"
article(
    "文章ID"
    id: Int! @eq
): Article
@model(name: "\\app\\test\\model\\api\\ArticleModel", scopes: ["published"])
@find

Copy after login

支持分页 paginate

articles: ArticlePagination
@model(name: "\\app\\test\\model\\api\\ArticleModel", scopes: ["published"])
@paginate(perPage: 15)

Copy after login

查询条件 where

articles(
    title: String
): ArticlePagination
@model(name: "\\app\\test\\model\\api\\ArticleModel", scopes: ["published"])
@where(value: { title: ["like", "$title"] })
@paginate(perPage: 15)

Copy after login

延迟加载 defer

// Type
type article {
    ...
    category: Category @defer(resolver: "\\app\\test\\loaders\\Cms@getCategoryById", keys: "category_id")
}

type Category {
    id: Int
    parent_id: Int
    title: String
    parent: Category @defer(resolver: "\\app\\test\\loaders\\Cms@getCategoryById", keys: "parent_id")
}

Copy after login

除此以外，还有包括auth权限管理、resolver自定义处理方法、date时间格式化、validate验证器、water打码脱敏、upper转大写、lower转小写等各种指令。
