需要从带有 JSON 响应的 POST 请求中提取数据

【问题标题】：Need to extract data from POST request with JSON response需要从带有 JSON 响应的 POST 请求中提取数据
【发布时间】：2023-04-12 07:10:01
【问题描述】：

我有一个 JSON 响应，我正在尝试从中收集数据。大多数数据是不需要的，但它的结构方式我很难弄清楚如何获取我需要的数据。字符串和值的配对有点奇怪。

我需要能够使用 PHP 提取数据，并且我需要来自特征字段的信息。具体来说，我需要提取“qualificationTier”的值。

我将使用什么来从这个 JSON 响应中提取该字符串/值？

【问题讨论】：

    标签： php arrays json


    【解决方案1】：

    检查这是否有效。

    <?php

$data = json_decode($your_json);

$qualificationTier = "qualificationTier"; 

// qualificationTier name is at position 13 in characteristic array

$QualificationTierName = $data->site->place->characteristic[13]->name;

$QualificationTierValue = "";

// Confirm indeed if the string name at position 13 in characteristics is indeed qualificationTier before retrieving the value at the same position
if(strcmp($qualificationTier, $QualificationTierName) == 0 ){

    // qualificationTier value is at position 13 in characteristic array
    $QualificationTierValue = $data->site->place->characteristic[13]->value;
    echo "QualificationTier Name : " + $QualificationTierName; 
    echo "QualificationTier Value : " + $QualificationTierValue;
}

?>

    【讨论】：

    • 好的，所以这个不起作用，因为qualificationTier 位置会根据地址是否具有SUITE 值而变化。所以我认为这不会奏效。虽然代码很容易理解。非常感谢您的帮助。
    【解决方案2】：

    一种简单的方法是循环数组并在名称与您的字段匹配时获取值。您应该首先解码 json 响应，以便您可以使用一个对象。然后在匹配时循环并设置变量。

    <?php

$response = json_decode($_POST['json-name']);

$qualificationTier = null;

foreach ($response->site->place->characteristic as $c) {
    if ($c->name === 'qualificationTier') {
        $qualificationTier = $c->value;
    }
}

    【讨论】：

    • 所以我一直在努力解决这个问题，但我无法让它发挥作用。 $response = curl_exec($curl); curl_close($curl);这是紧接在我要输入的代码之前的代码。我会使用 $reponse = json_decode($_POST[$reponse]);
    • 啊，我明白了，如果通过 curl 获取 JSON，您应该首先建立连接。然后使用 curl_exec 获取响应。已接受答案中的示例：*.com/questions/16700960/…。所以 json_decode 是 curl_exec() 的结果。
