uniapp 设置缓存时间

		let expire = nowTime + Number(seconds);
		uni.setStorageSync(key,JSON.stringify(value) + '|' +expire)
		console.log('已经把' + key + '存入缓存,过期时间为' + expire)
	} else if (key && !value) {
		let val = uni.getStorageSync(key);
		if (val) {
			// 缓存存在，判断是否过期
			let temp = val.split('|')

				console.log(key + '缓存已失效')
