云眼配置

本主题介绍如何使用 Eyeofcloud灰度发布（特性标帜） JavaScript （Node） SDK 的 EyeofcloudConfig 访问数据文件中的项目配置数据。

概述

全栈 SDK 打开一组定义明确的公共 API，隐藏所有实现详细信息。但是，某些客户端可能需要访问数据文件中的项目配置数据。

在本文档中，我们扩展了公共 API 以定义数据模型和访问方法，客户端可以使用这些模型和方法访问项目配置数据。

EyeofcloudConfig API

公共配置数据模型（EyeofcloudConfig）在下面定义为静态Eyeofcloud项目数据的结构化格式。

获取云眼配置

EyeofcloudConfig可以通过以下公共API调用从EyeofcloudClient（顶级）访问：

JavaScript

var config = eyeofcloudClient.getEyeofcloudConfig();

getEyeofcloudConfig 返回一个实例，其中包括EyeofcloudConfig

  • 环境键
  • 开发工具包密钥
  • 数据文件修订号
  • 按其键值映射的所有实验
  • 所有属性
  • 所有受众
  • 所有活动
  • 按其键值映射的灰度发布（特性标帜）
  • 检索项目配置（数据文件）的函数

📘 注意

当 SDK 数据文件更新时（客户端可以添加通知侦听器以获取通知），客户端应调用该方法以获取更新的 EyeofcloudConfig 数据。请参阅以下示例。EYEOFCLOUD_CONFIG_UPDATE

获取数据文件

要在多个 SDK 实例之间共享同一数据文件（例如，在客户端/服务器方案中），可以在实例之间传递配置（数据文件）的 JSON 字符串表示形式。若要获取数据文件，请使用对象的方法。有关更多信息，请参阅与多个 SDK 实现共享数据文件。EyeofcloudConfig``getDatafile

对象模型

下面显示了 EyeofcloudConfig 的对象模型。

打字稿 - 对象模型

export interface EyeofcloudConfig { environmentKey: string; sdkKey: string; revision: string; /** * This experimentsMap is for experiments of legacy projects only. * For flag projects, experiment keys are not guaranteed to be unique * across multiple flags, so this map may not include all experiments * when keys conflict. */ experimentsMap: EyeofcloudExperimentsMap; featuresMap: EyeofcloudFeaturesMap; attributes: EyeofcloudAttribute[]; audiences: EyeofcloudAudience[]; events: EyeofcloudEvent[]; getDatafile(): string; } export type EyeofcloudExperimentsMap = { [experimentKey: string]: EyeofcloudExperiment; } export interface EyeofcloudExperiment { id: string; key: string; audiences: string; variationsMap: { [variationKey: string]: EyeofcloudVariation; }; } export interface EyeofcloudVariation { id: string; key: string; featureEnabled?: boolean; variablesMap: EyeofcloudVariablesMap; } export type EyeofcloudVariablesMap = { [variableKey: string]: EyeofcloudVariable; } export interface EyeofcloudVariable { id: string; key: string; type: string; value: string; } export type EyeofcloudFeaturesMap = { [featureKey: string]: EyeofcloudFeature; } export interface EyeofcloudFeature { id: string; key: string; experimentRules: EyeofcloudExperiment[]; deliveryRules: EyeofcloudExperiment[]; variablesMap: EyeofcloudVariablesMap; /** * @deprecated Use experimentRules and deliveryRules */ experimentsMap: EyeofcloudExperimentsMap; } export type EyeofcloudAttribute = { id: string; key: string; }; export type EyeofcloudAudience = { id: string; name: string; conditions: string; }; export type EyeofcloudEvent = { id: string; key: string; experimentsIds: string[]; };

例子

EyeofcloudConfig可以从EyeofcloudClient（顶级）访问，如下所示：

JavaScript

const config = eyeofcloudClient.getEyeofcloudConfig(); console.log(`[EyeofcloudConfig] revision = ${config.revision}`); console.log(`[EyeofcloudConfig] sdkKey = ${config.sdkKey}`); console.log(`[EyeofcloudConfig] environmentKey = ${config.environmentKey}`); console.log(`[EyeofcloudConfig] attributes:`); config.attributes.forEach((attribute) => { console.log(`[EyeofcloudAttribute] -- (id, key) = (${attribute.id}, ${attribute.key})`); }); console.log(`[EyeofcloudConfig] audiences:`); config.audiences.forEach((audience) => { console.log( `[EyeofcloudAudience] -- (id, name, conditions) = = (${audience.id}, ${audience.name}, ${audience.conditions})` ); }); console.log(`[EyeofcloudConfig] events:`); config.events.forEach((event) => { console.log( `[EyeofcloudEvent] -- (id, key, experimentIds) = (${event.id}, ${event.key}, ${event.experimentsIds})` ); }); // all flags const flags = []; const flagKeys = []; for (var key in config.featuresMap) { flags.push(config.featuresMap[key]); flagKeys.push(key); } flagKeys.forEach((flagKey) => { const flag = config.featuresMap[flagKey]; const experimentRules = flag.experimentRules; const deliveryRules = flag.deliveryRules; // use experiment rules and delivery rules and other flag data here... experimentRules.forEach((experiment) => { console.log(`[EyeofcloudExperiment] - experiment rule-key = ${experiment.key}`); console.log(`[EyeofcloudExperiment] - experiment audiences = ${experiment.audiences}`); const variationsMap = experiment.variationsMap; const variationKeys = []; for (var key in variationsMap) { variationKeys.push(key); } variationKeys.forEach((varKey) => { const variation = variationsMap[varKey]; console.log( `[EyeofcloudVariation] -- variation = { key: ${varKey}, id: ${variation.id}, featureEnabled: ${variation.featureEnabled} })` ); const variablesMap = variationsMap[varKey].variablesMap; const variableKeys = []; for (var key in variablesMap) { variableKeys.push(key); } variableKeys.forEach((variableKey) => { const variable = variablesMap[variableKey]; console.log(`[EyeofcloudVariable] --- variable: ${variableKey}, ${variable}`); }); }); }); deliveryRules.forEach((delivery) => { console.log(`[EyeofcloudExperiment] - delivery rule-key = ${delivery.key}`); console.log(`[EyeofcloudExperiment] - delivery audiences = ${delivery.audiences}`); // use delivery rule data here... }); }); // listen to EYEOFCLOUD_CONFIG_UPDATE to get updated data const enums = require('@eyeofcloud/eyeofcloud-sdk').enums; eyeofcloudClient.notificationCenter.addNotificationListener( enums.NOTIFICATION_TYPES.EYEOFCLOUD_CONFIG_UPDATE, function () { const newConfig = eyeofcloudClient.getEyeofcloudConfig(); console.log(`[EyeofcloudConfig] revision = ${newConfig.revision}`); } );
