分桶方法decide
分桶方法decide
本主题概述了 JavaScript（浏览器）SDK 的判定方法，这些方法可用于在云眼灰度发布（特性标帜）AB实验中为用户返回标帜判定。
使用 Decide 方法返回用户的标帜决策。标帜决策包括标帜启用/禁用状态和标帜变体。
本页介绍以下决策方法：
决定
版本
SDK 4.5 及更高版本
描述
返回用户的标帜键的决策结果。决策结果在 EyeofcloudDecision 对象中返回，并包含传递标帜规则所需的所有数据。
Decide 是 UserContext 对象的一种方法。有关详细信息，请参阅 EyeofcloudUserContext。
有关返回的决策对象的详细信息，请参阅 EyeofcloudDecision 。
参数
下表描述了 Decide 方法的参数：

旗键
字符串
灰度发布（特性标帜）的键

云眼分桶结果 EyeofcloudDecision选项
下面的示例演示如何在任何 Decide 方法上单独设置选项，或在实例化 Eyeofcloud 客户端时将其设置为全局默认值。请参见初始化软件开发工具包。
JavaScript
const eyeofcloudSdk = require('@eyeofcloud/eyeofcloud-sdk'); const eyeofcloudOptions = require('@eyeofcloud/eyeofcloud-sdk').EyeofcloudDecideOption; // set global default decide options when initializing the client const eyeofcloudClient = eyeofcloudSdk.createInstance({ sdkKey: '<YOUR_SDK_KEY>', defaultDecideOptions: [eyeofcloudOptions.DISABLE_DECISION_EVENT], }); eyeofcloudClient.onReady().then(() => { const user = eyeofcloudClient.createUserContext('user123'); // set additional options in a decide call const decisionResultsMap = user.decideAll( [ eyeofcloudOptions.ENABLED_FLAGS_ONLY, eyeofcloudOptions.IGNORE_USER_PROFILE_SERVICE, ] ); });
下表显示了云眼决策选项的详细信息。
云眼分桶结果 EyeofcloudDecision选项枚举
如果设置：
EyeofcloudDecideOption.DISABLE_DECISION_EVENT
防止访问者在仍收到变体的同时触发展示，从而禁止在“结果”页面上显示 Decide 方法的结果。
此设置可能是为什么决策事件调度枚举在返回的 falseEyeofcloudDecision object or the DECIDE notification listener payload.
EyeofcloudDecideOption.ENABLED_FLAGS_ONLY
Return decisions for enabled flags only. This is a valid option only for methods that decide multiple flags, like the Decide All method. This option is ignored if it is invalid. When this option is not set, the SDK returns all decisions regardless of whether the flag is enabled or not.
EyeofcloudDecideOption.IGNORE_USER_PROFILE_SERVICE
When set, the SDK bypasses UPS (both lookup and save) for the decision.
When this option is not set, UPS overrides audience targeting, traffic allocation, and experiment mutual exclusion groups.
EyeofcloudDecideOption.INCLUDE_REASONS
Return log messages in the Reasons field of EyeofcloudDecision object. Note that unlike info or debug messages, critical error messages are always returned, regardless of this setting.
EyeofcloudDecideOption.EXCLUDE_VARIABLES
Exclude flag variable values from the decision result. Use this option to minimize the returned decision by skipping large JSON variables.
Returns
The Decide method returns an EyeofcloudDecision object. For more information, see EyeofcloudDecision.
If the method encounters a critical error (SDK not ready, invalid flag key, etc), then it returns a decision with a null Variation Key field and populates the Reasons field with error messages (regardless of the Include Reasons option).
Example Decision
The following is an example of calling the Decide method and accessing the returned EyeofcloudDecision object:
JavaScript
// create the user and decide which flag rule & variation they bucket into var attributes = { logged_in: true }; var user = eyeofcloudClient.createUserContext('user123', attributes); var decision = user.decide('product_sort'); var variationKey = decision['variationKey']; // Did the decision fail with a critical error? if (variationKey === null) { console.log(' decision error: ', decision['reasons']); } // flag enabled state: var enabled = decision['enabled']; // String variable value: var value = decision.variables['sort_method']; // all variable values var allVarValues = decision['variables']; // variation. if null, decision fail with a critical error var variationKey = decision['variationKey']; // flag decision reasons var reasons = decision['reasons']; // user for which the decision was made var userContext = decision['userContext'];
Side Effects
Invokes the notification listener if this listener is enabled.DECISION
Decide All
Returns decisions for all active (unarchived) flags for a user.
See EyeofcloudDecision for details.
Version
SDK 4.5 and higher
Description
Use the Decide All method to return a map of flag decisions for a user.
Parameters
The following table describes parameters for the Decide All method:
Parameter
Type
Description
options (optional)
Array
Array of EyeofcloudDecideOption enums. See EyeofcloudDecideOption.
Returns
The Decide All method returns a map of EyeofcloudDecisions. For more information, see EyeofcloudDecision.
If the method fails for all flags (for example, the SDK isn't ready or the user context is invalid), then it returns an empty map. If the method detects an error for a specific flag, it returns error messages in the Reasons field of the decision for that flag.
Examples
The following is an example of getting flags for the user with the Decide All call:
JavaScript
var attributes = { logged_in: true }; var user = eyeofcloudClient.createUserContext('user123', attributes); // make decisions for all active (unarchived) flags in the project for a user var decisions = user.decideAll(); // or only for enabled flags var decisions = user.decideAll([EyeofcloudDecideOption.ENABLED_FLAGS_ONLY]); var flagKeys = Object.keys(decisions); var decisionForFlag1 = decisions['flag_1'];
Side effects
Invokes the notification listener for each decision if this listener is enabled. DECISION
Decide For Keys
The Decide For Keys method returns an object of decision results mapped by flag keys.
Version
SDK v4.5 and higher
Description
Get a map of flag decisions for an array of flag keys.
Parameters
The following table describes parameters for the Decide For Keys method:
Parameter
Type
Description
keys
Array
Array of string flag keys.
options (optional)
Array
Array of EyeofcloudDecideOption enums. See EyeofcloudDecideOption.
Returns
Returns a map of EyeofcloudDecisions. For more information, see EyeofcloudDecision.
If the method fails for all flags (for example, the SDK isn't ready or the user context is invalid), then it returns an empty map. If the method detects an error for a specific flag, it returns error messages in the Reasons field of the decision for that flag.
Example
The following is an example of getting specified flags for the user:
JavaScript
// make a decisions for specific enabled flags var keys = ['flag_1', 'flag_2']; var decisions = user.decideForKeys(keys); var decision1 = decisions['flag_1']; var decision2 = decisions['flag_2'];
Side effects
Invokes the notification listener for each decision if this listener is enabled. DECISION

创建用户上下文
介绍创建用户上下文方法，该方法为云眼灰度发布（特性标帜）AB实验中的标帜决策和事件创建用户上下文。
此方法的目的是创建用户并设置用户上下文一次，因此不必在每次做出标帜决策或跟踪事件时都指定用户。可以定义多个用户上下文。系统将用户上下文作为运行时对象返回，否则不会持久化。
版本
1.0.0-beta 或更高版本
描述
此调用为标帜决策和事件创建用户上下文。可以在 Eyeofcloud 客户端实例上成功调用此方法，甚至在完全配置实例之前也是如此。
参数
下表列出了必需参数和可选参数：
参数
类型
描述
(必选)用户 ID
字符串
用户的 ID。
属性
可选
Map
自定义键值字符串对的映射，指定系统用户用于受众群体定位的用户的属性。有关更多详细信息，请参阅以下部分。
受众群体属性
为用户设置自定义受众群体属性，可以使用这些属性来定位受众群体。可以将字符串、数字、布尔值和 nil 作为自定义用户属性值传递。如果要根据他们使用的应用程序变体定位访问群体，还可以传入格式为语义变体的字符串，然后在 Eyeofcloud 应用中定义受众条件。version
🚧 重要
在访问群体评估期间，如果没有为给定的访问群体条件传递有效的属性值（例如，如果在受众群体条件需要布尔值时传递字符串，或者忘记传递值），则系统会跳过该条件。发生这种情况时，SDK 日志会包含警告。
返回
返回一个 EyeofcloudUserContext 对象。有关详细信息，请参阅云眼用户上下文。
例
Dart
// option 1: create a user, then set attributes var user = await flutterSDK.createUserContext("user123"); var attributes = <String, dynamic>{}; attributes["is_logged_in"] = false; attributes["app_version"] = "1.3.2"; user!.setAttributes(attributes); // option 2: pass attributes when creating the user var attributes = <String, dynamic>{}; attributes["is_logged_in"] = false; attributes["app_version"] = "1.3.2"; var eyeofcloudUserContext = await eyeofcloudClient.createUserContext("user123", attributes);
