参考以下示例代码，注意只有对象的get/set方法才能绑定this指针。
class ReflectClass {
private a = 'a';
get getA() {
return () => {
return this.a;
};
}
set setA(a: string) {
this.a = a;
}
}
function testInvoke() {
const reflectClass = new ReflectClass();
const fn: Function = Reflect.get(reflectClass, 'getA', reflectClass);
console.info(fn());
}
@Entry
@Component
struct ReflectBoundThis {
aboutToAppear(): void {
testInvoke();
}
build() {
}
}
