从 PHP 中的受保护对象读取数据
Read data from protected object in PHP
我在 PHP 中有这段代码(它只是从 API 中检索了一些交付方法,API 是第 3 方)
use MPAPI\Services\DeliveryMethods;
use MPAPI\Services\Deliveries;
use MPAPI\Entity\PartnerDelivery;
use MPAPI\Entity\GeneralDelivery;
$deliveryMethods = new DeliveryMethods($mpapiClient);
$response = $deliveryMethods->get();
var_dump($response);
响应是:
array(2) {
[0]=>
object(MPAPI\Entity\DeliveryMethod)#35 (1) {
["data":protected]=>
array(7) {
["id"]=>
string(4) "Test"
["title"]=>
string(18) "Testovacia doprava"
["price"]=>
int(10)
["cod_price"]=>
int(10)
["free_limit"]=>
int(0)
["delivery_delay"]=>
int(5)
["is_pickup_point"]=>
bool(false)
}
}
[1]=>
object(MPAPI\Entity\DeliveryMethod)#36 (1) {
["data":protected]=>
array(7) {
["id"]=>
string(3) "UPS"
["title"]=>
string(22) "Kuriérska služba UPS"
["price"]=>
int(5)
["cod_price"]=>
int(0)
["free_limit"]=>
int(0)
["delivery_delay"]=>
int(4)
["is_pickup_point"]=>
bool(false)
}
}
}
我想在 PHP 中访问它,所以我的 foreach 循环看起来像:
<?php foreach ($response[0]->data as $item) { ?>
// ...
<?php } ?>
但是我得到一个错误:
Fatal error: Uncaught Error: Cannot access protected property
MPAPI\Entity\DeliveryMethod::$data in
/data/web/virtuals/175241/virtual/www/doprava.php:39 Stack trace: #0
{main} thrown in /data/web/virtuals/175241/virtual/www/doprava.php on
line 39
那么如何正确读取PHP中的这个数据呢?
如果我像这样更改 foreach 循环:
<?php foreach ($response as $item) { ?>
// ...
<?php } ?>
我会得到另一个错误:
Fatal error: Uncaught Error: Cannot use object of type
MPAPI\Entity\DeliveryMethod as array
在 API 的文档中没有任何内容 https://github.com/mallgroup/mpapi-client-php/blob/master/doc/DELIVERIES.md
我同意你的看法,文档对此不太清楚。
如果你查看 the source,你可以看到 class MPAPI\Entity\DeliveryMethod
有这个方法 returns 数据作为数组:
/**
* @see \MPAPI\Entity\AbstractEntity::getData()
*/
public function getData()
{
return [
self::KEY_ID => $this->getId(),
self::KEY_TITLE => $this->getTitle(),
self::KEY_PRICE => $this->getPrice(),
self::KEY_COD_PRICE => $this->getCodPrice(),
self::KEY_FREE_LIMIT => $this->getFreeLimit(),
self::KEY_DELIVERY_DELAY => $this->getDeliveryDelay(),
self::KEY_PICKUP_POINT => $this->isPickupPoint()
];
}
所以,你会做这样的事情
<?php
$methodList = $deliveryMethods->get();
foreach ($methodList as $method) {
$methodData = $method->getData();
// OR
$methodTitle = $method->getTitle()
// ...
}
?>
