GraphQL

GraphQL 根底

参照 Getting started with GraphQL Java and Spring Boot 这篇文章学习即可

PS:能够应用 brew install --cask graphql-playground 装置 graphql for mac 客户端。

IDEA 怎么调试 GraphQL 利用

装置 JS GraphQL 插件

点击 JS GraphQL 装置插件

GraphQL 定义

schema.graphqls

type Query {bookById(id: ID): Book
}

type Book {
    id: ID
    name: String
    pageCount: Int
    author: Author
}

type Author {
    id: ID
    firstName: String
    lastName: String
}

GraphQL 配置文件

.graphqlconfig

{
  "name": "book-details",
  "schemaPath": "schema.graphqls",
  "extensions": {
    "endpoints": {
      "Default GraphQL Endpoint": {
        "url": "http://localhost:8080/graphql", // 申请门路
        "headers": {"user-agent": "JS GraphQL"},
        "introspect": false
      }
    }
  }
}

创立一个查问文件

query.graphql

# {"id": "book-1"}
query queryData($id: ID) {bookById(id: $id) {
        id name pageCount author {id firstName lastName}
    }
}

GraphQL 脚本目录构造

resources
├── .graphqlconfig  # 配置文件
├── query.graphql   # 查问文件
└── schema.graphqls # 定义文件 

执行后果

GraphQL 在 Skywalking 中的利用

graphql 协定文件门路:oap-server/server-query-plugin/query-graphql-plugin/src/main/resources/query-protocol 

GraphQL 配置文件

.graphqlconfig

{
  "name": "skywalking",
  "schemaPath": "schema.graphql",
  "extensions": {
    "endpoints": {
      "Default GraphQL Endpoint": {
        "url": "http://localhost:8080/graphql",
        "headers": {"user-agent": "JS GraphQL"},
        "introspect": true
      }
    }
  }
}

创立一个查问文件

query.graphql

query queryData {
    readMetricsValues(duration: {start: "2021-07-03 1400",end: "2021-07-03 1401", step: MINUTE},
        condition: {
            name: "instance_jvm_thread_runnable_thread_count",
            entity: {
                scope: ServiceInstance,
                serviceName: "business-zone::projectA",
                serviceInstanceName: "e8cf34a1d54a4058a8c98505877770e2@192.168.50.113",
                normal: true
            }
        }
    ) {label values{ values{ id value}}
    }
}

执行后果

{
  "data": {
    "readMetricsValues": {
      "values": {
        "values": [
          {
            "id": "202107031400_YnVzaW5lc3Mtem9uZTo6cHJvamVjdEE=.1_ZThjZjM0YTFkNTRhNDA1OGE4Yzk4NTA1ODc3NzcwZTJAMTkyLjE2OC41MC4xMTM=",
            "value": 22
          },
          {
            "id": "202107031401_YnVzaW5lc3Mtem9uZTo6cHJvamVjdEE=.1_ZThjZjM0YTFkNTRhNDA1OGE4Yzk4NTA1ODc3NzcwZTJAMTkyLjE2OC41MC4xMTM=",
            "value": 22
          }
        ]
      }
    }
  }
}
