requestSubscribeMessage:fail must be invoked by user tap gesture

使用uniapp开发抖音小程序报错：requestSubscribeMessage:fail must be invoked by user tap gesture

解决方法：
调用的标签加上data-eventsync=“true” 就可以了，目前只测试了抖音小程序的调用

	<button
	  data-eventsync="true"  
	  @click="requestSubscribeMessage()"
	>
		立即订阅
	</button>

	const requestSubscribeMessage = () => {
		uni.requestSubscribeMessage({
			tmplIds: ['1234567'],
			async success(data) {
			  console.log(data, '消息订阅成功======');
			  emit("subscribeMessageSuccess");
			},
			fail(err) {
		      emit("subscribeMessageError");
			},
		});
	};
