Question

我试图从php中的以下JSON代码中提取销售ID。我想要获得的输出是：

1KE4800207592173L

JSON代码。

{
  "transactions": [
  {
    "description": "This is the payment transaction description.",
    "related_resources": [
    {
      "sale":
      {
        "id": "1KE4800207592173L",
        "create_time": "2013-01-30T23:44:26Z",
        "update_time": "2013-01-30T23:44:28Z",
        "state": "completed",
        "parent_payment": "PAY-34629814WL663112AKEE3AWQ",
        "links": [
        {
          "href": "https://api.sandbox.paypal.com/v1/payments/sale/1KE4800207592173L",
          "rel": "self",
          "method": "GET"
        }]
      }
    }]
  }],
  "links": [
  {
    "href": "https://api.sandbox.paypal.com/v1/payments/payment/PAY- 34629814WL663112AKEE3AWQ",
    "rel": "self",
    "method": "GET"
  }]
}

任何帮助尝试将其作为PHP JSON或数组引用都将非常感激。感谢。

编辑：

我尝试过以下方法：

$response1 = json_decode($response);
$payment_id = $response1->transactions->related_resources->sale->id;
$payment_id = print_r($payment_id, true);

和

$response1 = json_decode($response);
$payment_id = $response1->transactions->related_resources[0]->sale->id;
$payment_id = print_r($payment_id, true);

似乎都不起作用。

原始JSON与此处可找到的相同。 https://developer.paypal.com/docs/integration/direct/express-checkout/integration-jsv4/advanced-payments-api/execute-payments/如果有帮助的话。

试试这个

使用 json_decode 将json字符串转换为对象

 $a = '{
      "transactions": [
      {
        "description": "This is the payment transaction description.",
        "related_resources": [
        {
          "sale":
          {
            "id": "1KE4800207592173L",
            "create_time": "2013-01-30T23:44:26Z",
            "update_time": "2013-01-30T23:44:28Z",
            "state": "completed",
            "parent_payment": "PAY-34629814WL663112AKEE3AWQ",
            "links": [
            {
              "href": "https://api.sandbox.paypal.com/v1/payments/sale/1KE4800207592173L",
              "rel": "self",
              "method": "GET"
            }]
          }
        }]
      }],
      "links": [
      {
        "href": "https://api.sandbox.paypal.com/v1/payments/payment/PAY- 34629814WL663112AKEE3AWQ",
        "rel": "self",
        "method": "GET"
      }]
    }';



    print_r(json_decode($a)->transactions[0]->related_resources[0]->sale->id);

使用

$array = json_decode($jsonScriptVariable, true);

它将转换为数组，然后您可以轻松访问。

<?php
$var = '{
  "transactions": [
  {
    "description": "This is the payment transaction description.",
    "related_resources": [
    {
      "sale":
      {
        "id": "1KE4800207592173L",
        "create_time": "2013-01-30T23:44:26Z",
        "update_time": "2013-01-30T23:44:28Z",
        "state": "completed",
        "parent_payment": "PAY-34629814WL663112AKEE3AWQ",
        "links": [
        {
          "href": "https://api.sandbox.paypal.com/v1/payments/sale/1KE4800207592173L",
          "rel": "self",
          "method": "GET"
        }]
      }
    }]
  }],
  "links": [
  {
    "href": "https://api.sandbox.paypal.com/v1/payments/payment/PAY- 34629814WL663112AKEE3AWQ",
    "rel": "self",
    "method": "GET"
  }]
}';

$array = json_decode($var, true);
echo $array['transactions'][0]['related_resources'][0]['sale']['id'];

你可以使用简单的 json_decode（$ var）; 来提供对象，你可以访问

echo $array->transactions[0]->related_resources[0]->sale->id;

PHP JSON尝试从JSON数据中获取销售ID
