amp-html - amp-date-picker 返回不正确的日期

问题描述

使用amp-date-picker并使用它来保存amp-state两者event.start并event.end在所选日期后 1 天返回。

示例：我选择 5/15/2019 - 5/22/2019，它返回 5/16/2019 - 5/23/2019。

AMP.printState()

解决方案

经过大量搜索，我无法找到为什么我的日期返回不正确，并且发现 AMP 没有日期操作功能。我必须做的是通过创建一个日期编辑器脚本并使用amp-statesrc 调用它来破解系统。

安培代码：

<amp-state id="filterDates" src="https://www.test.com/date.php" [src]="(filterState.startDate != -1 || filterState.endDate != -1)?'https://www.test.com/date.php?start='+encodeURIComponent(filterState.startDate)+'&end='+encodeURIComponent(filterState.endDate):'https://www.test.com/date.php'"></amp-state>

PHP 脚本：

<?php
header('Content-type: application/json');
header('Access-Control-Allow-Credentials: true');
header('Access-Control-Allow-Origin: *');
header('AMP-Access-Control-Allow-Source-Origin: https://www.test.com');
header('Content-Type: application/json');

$return = array(
    'startDate' => -1,
    'endDate' => -1
);
if(isset($_GET['start']))
{
    $return['startDate'] = date("m/d/Y", strtotime("-1 day", strtotime($_GET['start'])));
}
if(isset($_GET['end']))
{
    $return['endDate'] = date("m/d/Y", strtotime("-1 day", strtotime($_GET['end'])));
}

echo json_encode($return);

希望这对将来的某人有所帮助，如果有人找到更好的解决方案，我会听到它。
