Let's talk about GraphQL implementation based on webman
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] }
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
支持分页 paginate
articles: ArticlePagination @model(name: "\\app\\test\\model\\api\\ArticleModel", scopes: ["published"]) @paginate(perPage: 15)
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)
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") }
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。

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

These methods are automatically called in certain situations, improving code flexibility and efficiency.
