如何从此 JSON 访问产品标题

Question

我检索到了一些这样的数据：

object(stdClass)[1]
  public 'status' => string 'ok' (length=2)
  public 'data' => 
    object(stdClass)[3]
      public 'sort_data' => 
        object(stdClass)[2]
          public 'sort_column' => string 'order_item_id' (length=13)
          public 'sort_order' => string 'asc' (length=3)
      public 'pager' => 
        object(stdClass)[4]
          public 'page' => int 1
          public 'item_per_page' => int 50
          public 'total_page' => int 1
          public 'total_rows' => int 21
      public 'form_data' => 
        array (size=0)
          empty
      public 'items' => 
        array (size=21)
          0 => 
            object(stdClass)[5]
              public 'order_item_id' => int 323360064
              public 'order_id' => int 111179028
              public 'variant' => 
                object(stdClass)[6]
                  public 'id' => int 17586275
                  public 'seller_id' => int 186764
                  public 'site' => string 'digikala' (length=8)
                  public 'is_active' => boolean true
                  public 'is_archived' => boolean false
                  public 'title' => string 'Mug' (length=115)
                  public 'product' => 
                    object(stdClass)[7]
                      public 'id' => int 3634323
                      public 'category_id' => int 6289
                      public 'title' => string 'Mug model series' (length=40)
                      public 'shipping_nature_id' => int 1
                      ...

这背后的代码在这里：

$curl = curl_init();

curl_setopt_array($curl, array(
  CURLOPT_URL => 'site_url',
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_ENCODING => '',
  CURLOPT_MAXREDIRS => 10,
  CURLOPT_TIMEOUT => 0,
  CURLOPT_FOLLOWLOCATION => true,
  CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
  CURLOPT_CUSTOMREQUEST => 'GET',
  CURLOPT_HTTPHEADER => array(
    'Content-Type: application/json, application/json;charset=UTF-8',
    'Authorization: {{token}}'
  ),
));

$response = curl_exec($curl);

var_dump(json_decode($response));

现在我需要分别访问这些值。例如我想得到public 'title' => string 'Mug model series'。我该怎么做？

Answer 1

你可以告诉 json_decode() 返回一个数组而不是一个对象：

$response = json_decode($response,true);

Answer 2

现在我需要分别访问这些值。例如我 想要公开 'title' => string 'Mug model series'

...
$object = json_decode($response);

echo $object->data->items[0]->variant->product->title;
// Mug model series

[0] 表示数组中的第一项，所以如果你想循环它：

foreach ($object->data->items as $item) 
  echo $item->variant->product->title;

Answer 3

首先你需要通过使用将对象转换为数组

$response = json_decode($response, true);

解码响应并获取数组而不是对象后，您可以通过键入以下内容访问数据

echo $response->data->items[0]->order_id;
// output : 111179028

假设您必须在表格中显示每个数据，或者您需要这样的 foreach 循环：

foreach($response->data->items as $item){
?>
 <h1>
  <?php 
   echo $item->variant->seller_id; 
  ?>
 </h1>
 <h2>
  <?php
   echo $item->variant->product->title
  ?>
 </h2>
<?php
}
?>

我希望这个答案对你有用

Answer 4

试试这个

$json = '{"a":1,"b":2,"c":3,"d":4,"e":5}';

解码 JSON 字符串

var_dump(json_decode($response))
$json= json_decode($json,true);

Answer 5

注意：如果您只是打印这样的数据，将来会更容易。

echo "<pre>";
print_r($response);

现在已经不碍事了，考虑到您所做的json_decode($response, true)，您收到的数据看起来像下面的数据（当第二个参数为您提供关联数组时为真）。

[
 "parentStdClass" => [  // (Your question starts from here as stdclass has index 1 probably array)
     ....
     "data" => [
           ...unrelatedData removed form this eg,
           "items" => [ // you have 21 items
             .... 20 items,
             [

                 ...,
                 "variant" => [
                    ...,
                    "title" => "Some title", //variant title

                    "product" => [ // 7 items are here
                       ...,
                       [
                           'title' => 'Mug model series',
                       ] 
                    ]
                 ]
             ],

   
           ],
     ]
 ]
]  

现在要获得您需要做的第一个产品的标题。

$response = json_decode($response, true);
// Put what the key name is instead of 0 if it's associative array
$questionStartingArray = $response[0];

$data = $questionStartingArray['data'];
// Give you all items
$items = $questionStartingArray['items'];

// Gives you first item variant & title
$variant = $items[0]['variant'];
$variantTitle = $variant['title'];

// Gives you first variants product  & product title
$product = $variant['product'];
$productTitle = $product[0]['title'];
$allProductTitleInsideVariant = array_reduce($product , function($carry, $item){
   $carry[] = $item['title'];
   return $carry;
},[]);

如果您想要一个项目中的所有产品标题，则通过循环获取它。例如：

$productTitle = [];
$variantTitle = [];
foreach($items as $item) {
   foreach($item['variant'] as $variantItem) {
      $variantTitle[] = $variantItem['title'];
      foreach($variantItem['product'] as $productItem) {
         $productTitle[] = $productItem['title'];
      } 

   } 
}

echo "<pre>";
print_r($productTitle);
print_r($variantTitle);

您将在 items 数组中获取所有产品标题。
