Question

我正在从bigCommerce api创建以下对象，如下所示：

[
{
    "id": 412,
    "option_id": 37,
    "display_name": "testSteveMemory",
    "sort_order": 0,
    "is_required": true
},
{
    "id": 413,
    "option_id": 34,
    "display_name": "Hard Drive (desktop)",
    "sort_order": 1,
    "is_required": true
},
{
    "id": 414,
    "option_id": 24,
    "display_name": "Include Keyboard & Mouse",
    "sort_order": 2,
    "is_required": true
},
{
    "id": 415,
    "option_id": 33,
    "display_name": "Memory",
    "sort_order": 3,
    "is_required": true
}
]

我使用以下方法将其转换为PHP数组：

$curlProductOptions = json_decode($curlProductOptions, true);

然后我遍历数组并获取该option_id的选项

$allOptions = array();  
foreach($curlProductOptions as $value){
    //echo $value['option_id'].'<br>';
    $option_id = $value['option_id'];


$product_url = $url.'/api/v2/options/'.$option_id.'/values.json';
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $product_url);
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($curl, CURLOPT_USERPWD, $username . ":" . $password);
curl_setopt($curl, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
curl_setopt($curl, CURLOPT_ENCODING, "");
$curlProductData = curl_exec($curl);
array_push($allOptions,$curlProductData);
curl_close($curl);
}

然后我使用echo输出数组$ allOptions，我在移动应用程序中将其作为json使用。如果我使用

echo $curlProductData.'<br>'

我得到以下内容：

[{"id":112,"option_id":37,"label":"1 gig ram","sort_order":0,"value":"1 gig ram"},{"id":113,"option_id":37,"label":"2 gig ram","sort_order":1,"value":"2 gig ram"},{"id":114,"option_id":37,"label":"4 gig ram","sort_order":2,"value":"4 gig ram"}]
[{"id":104,"option_id":34,"label":"80GB SATA","sort_order":0,"value":"80GB SATA"}]
[{"id":90,"option_id":24,"label":"Yes","sort_order":0,"value":"Yes"},{"id":91,"option_id":24,"label":"No","sort_order":1,"value":"No"}]
[{"id":102,"option_id":33,"label":"1GB DDR2 RAM (default)","sort_order":0,"value":"1GB DDR2 RAM (default)"},{"id":103,"option_id":33,"label":"2GB DDR2 RAM (+ $15.00)","sort_order":1,"value":"2GB DDR2 RAM (+ $15.00)"}]

如果我使用以下任何一种回声：

echo $allOptions;
json_encode($allOptions);
var_dump($allOptions);

将数据返回到移动应用程序时出现解析错误。即它没有将结果识别为json数组。

我在假设：

$allOptions = array()将$allOptions声明为数组
我在循环中为每个$allOptions填充$curlProductData。

我在这里做错了什么？

我现在正在使用：

echo "[".implode(",\n",$allOptions)."]";

我现在收到以下内容：

[[{"id":112,"option_id":37,"label":"1 gig ram","sort_order":0,"value":"1 gig ram"},{"id":113,"option_id":37,"label":"2 gig ram","sort_order":1,"value":"2 gig ram"},{"id":114,"option_id":37,"label":"4 gig ram","sort_order":2,"value":"4 gig ram"}], [{"id":104,"option_id":34,"label":"80GB SATA","sort_order":0,"value":"80GB SATA"}], [{"id":90,"option_id":24,"label":"Yes","sort_order":0,"value":"Yes"},{"id":91,"option_id":24,"label":"No","sort_order":1,"value":"No"}], [{"id":102,"option_id":33,"label":"1GB DDR2 RAM (default)","sort_order":0,"value":"1GB DDR2 RAM (default)"},{"id":103,"option_id":33,"label":"2GB DDR2 RAM (+ $15.00)","sort_order":1,"value":"2GB DDR2 RAM (+ $15.00)"}]]

但我无法正确映射？

Answer 1

您正在逐个输出多个数组。您一次只能拥有一个JSON对象。

最好是坚持使用数组并使用echo json_encode($curlProductData)输出数据。

Answer 2

以下解决方案将每个项目放在一个数组中：

foreach($curlProductOptions as $value){
    //echo $value['option_id'].'<br>';
    $option_id = $value['option_id'];


    $product_url = $url.'/api/v2/options/'.$option_id.'/values.json';
    $curl = curl_init();
    curl_setopt($curl, CURLOPT_URL, $product_url);
    curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($curl, CURLOPT_USERPWD, $username . ":" . $password);
    curl_setopt($curl, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
    curl_setopt($curl, CURLOPT_ENCODING, "");
    $curlProductData = curl_exec($curl);

    foreach(json_decode($curlProductData, true) as $key => $value) {
        $allOptions[] = $value; // [] is quicker than array_push() for single items
    }

    curl_close($curl);
}

如果您在问题中需要四个分组：

以下解决方案将每个项目放在一个数组中：

foreach($curlProductOptions as $value){
    //echo $value['option_id'].'<br>';
    $option_id = $value['option_id'];


    $product_url = $url.'/api/v2/options/'.$option_id.'/values.json';
    $curl = curl_init();
    curl_setopt($curl, CURLOPT_URL, $product_url);
    curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($curl, CURLOPT_USERPWD, $username . ":" . $password);
    curl_setopt($curl, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
    curl_setopt($curl, CURLOPT_ENCODING, "");
    $curlProductData = curl_exec($curl);

    $allOptions[] = json_decode($curlProductData, true);

    curl_close($curl);
}

现在json_encode($allOptions)将为您提供有效的json字符串。问题是当你只读1时，你试图传递4个json字符串。

Answer 3

如果您收到解析器错误，可能是因为echo $curlProductData.'<br>'之后缺少分号

Answer 4

$curlProductData = curl_exec($curl);
array_push($allOptions,$curlProductData);

问题是curl_exec正在返回一个字符串 - 该字符串可能是一个JSON字符串，但它仍然是一个字符串。

您的最终echo json_encode($allOptions)将是一个字符串数组，而不是您可能期望的多维数组。

你可以尝试的是echo "[".implode(",\n",$allOptions)."]";，因为这会产生一个多维数组。

但请记住，必须在循环之后完成此操作。如果你在循环中仍然这样做的话，你最终会得到多个输出，这会导致问题。
