使用UserAccessor访问用户属性 [英] Accessing user attributes using UserAccessor

问题描述

com.sap.cloud.sdk.cloudplatform.security.user.UserAccessor类允许我检索当前用户及其属性.

The class com.sap.cloud.sdk.cloudplatform.security.user.UserAccessor allows to me to retrieve the current user and it's attributes.

例如:

    Optional<UserAttribute> optionalfirstName = user.getAttribute("firstname"); 
    UserAttribute ua = optionalfirstName.get(); 

一旦检索到UserAttribute，它将具有两个属性名称"和值".但是，没有可用的方法来获取该值.我如何获得价值?

Once I have retrieved the UserAttribute, it has two properites "Name" and "Value". However there is no method available to get the Value. How can I access the value?

推荐答案

取决于所使用的SAP CP环境，UserAttribute是以下内容的实例:

Depending on the SAP CP environment you are using, the UserAttribute is an instance of:

• SimpleUserAttribute<String> on Neo
• CollectionUserAttribute<String>在Cloud Foundry上

• SimpleUserAttribute<String> on Neo
• CollectionUserAttribute<String> on Cloud Foundry

您可以通过将类型强制转换为所需实例来访问相应的值:

You can access the respective values by type-casting to the required instance:

if( ua instanceof SimpleUserAttribute ) {
    String value = (String) ((SimpleUserAttribute<?>)ua).getValue();
}
else if ( ua instanceof CollectionUserAttribute ) {
    Collection<?> values = ((CollectionUserAttribute<?>)ua).getValues();
}

注意:我们计划在以后的SDK版本中对此进行简化，以便返回StringUserAttribute和StringCollectionUserAttribute实例以便更方便地使用.

Note: We plan to simplify this in future releases of the SDK so that StringUserAttribute and StringCollectionUserAttribute instances are returned for more convenient consumption.
