参考示例：

@Entry
@Component
struct Index {
  @State message: string = 'Hello World';
  aboutToAppear() {

  }

  startAbilityTest() {
    let context = getContext(this) as common.UIAbilityContext;
    let wantInfo: Want = {
      bundleName: 'com.huawei.hmos.settings',
      abilityName: 'com.huawei.hmos.settings.MainAbility',
      // uri: 'wifi_entry',
    };
    context.startAbility(wantInfo)
      .then(() => {
        // ...
      })
      .catch((err:Error) => {
        // console.error(`Failed to startAbility. Code: ${err.code}, message: ${err.message}`);
      });
  }

  build() {
    Row() {
      Column() {
        Text(this.message)
          .fontSize(50)
          .fontWeight(FontWeight.Bold)
          .onClick(()=>{
            this.startAbilityTest()
          })
      }
      .width('100%')
    }
    .height('100%')
  }
}
