HarmonyOS 类如何实现带有index signature的接口？

Question

1、编写以下代码

import { insightIntent } from '@kit.IntentsKit'

class testClass implements insightIntent.IntentActionInfo {
}

2、报错如下：

Class 'testClass' incorrectly implements interface 'IntentActionInfo'. Index signature for type 'string' is missing in type 'testClass'. <ArkTSCheck>

Answer 1

不支持直接implements insightIntent.IntentActionInfo，参考示例如下：

class testClass implements insightIntent.InsightIntent {
  intentName: string;
  intentVersion: string;
  identifier: string;
  intentActionInfo: insightIntent.IntentActionInfo;
  intentEntityInfo: insightIntent.IntentEntityInfo;

  constructor(intentName: string,
    intentVersion: string,
    identifier: string,
    intentActionInfo: insightIntent.IntentActionInfo,
    intentEntityInfo: insightIntent.IntentEntityInfo) {
    this.intentName = intentName
    this.intentVersion = intentVersion
    this.identifier = identifier
    this.intentActionInfo = intentActionInfo
    this.intentEntityInfo = intentEntityInfo
  }
}
