HarmonyOS 鸿蒙Next Image组件或ImageKnife组件如何触发网络图片内容更新后的重新加载

尝试下ImageKnife组件的设置signature属性

[@Entry](/user/Entry)
[@Component](/user/Component)
struct TestRemoveCache {
  build() {
    Column() {
      Flex() {
        ImageKnifeComponent({
          imageKnifeOption: {
            loadSrc: "https://xxxxx",
            signature: "aa",
            progressListener: (progress: number) => {
              console.info("ImageKinfe:: call back progress = " + progress)
            }
          }
        }).width(100).height(100)
      }
}
.height(<span class="hljs-string">'100%'</span>).width(<span class="hljs-string">'100%'</span>)
}
