Question

我正在整合 PayPal 订阅。由于我有一个用户定义的计划，我必须相应地创建一个计划，我在 getplan.php 中使用以下 curl 请求创建了该计划：

$curl = curl_init();

curl_setopt_array($curl, array(
  CURLOPT_URL => "https://api-m.sandbox.paypal.com/v1/billing/plans",
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_ENCODING => "",
  CURLOPT_MAXREDIRS => 10,
  CURLOPT_TIMEOUT => 30,
  CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
  CURLOPT_CUSTOMREQUEST => "POST",
  CURLOPT_POSTFIELDS => "{\r\n  \"product_id\": \"PROD-65T41140NK6579847\",\r\n  \"name\": \"Video Streaming Service Plan\",\r\n  \"description\": \"Video Streaming Service basic plan\",\r\n  \"status\": \"ACTIVE\",\r\n  \"billing_cycles\": [\r\n    {\r\n      \"frequency\": {\r\n        \"interval_unit\": \"MONTH\",\r\n        \"interval_count\": 1\r\n      },\r\n      \"tenure_type\": \"TRIAL\",\r\n      \"sequence\": 1,\r\n      \"total_cycles\": 2,\r\n      \"pricing_scheme\": {\r\n        \"fixed_price\": {\r\n          \"value\": \"3\",\r\n          \"currency_code\": \"USD\"\r\n        }\r\n      }\r\n    },\r\n    {\r\n      \"frequency\": {\r\n        \"interval_unit\": \"MONTH\",\r\n        \"interval_count\": 1\r\n      },\r\n      \"tenure_type\": \"TRIAL\",\r\n      \"sequence\": 2,\r\n      \"total_cycles\": 3,\r\n      \"pricing_scheme\": {\r\n        \"fixed_price\": {\r\n          \"value\": \"6\",\r\n          \"currency_code\": \"USD\"\r\n        }\r\n      }\r\n    },\r\n    {\r\n      \"frequency\": {\r\n        \"interval_unit\": \"MONTH\",\r\n        \"interval_count\": 1\r\n      },\r\n      \"tenure_type\": \"REGULAR\",\r\n      \"sequence\": 3,\r\n      \"total_cycles\": 12,\r\n      \"pricing_scheme\": {\r\n        \"fixed_price\": {\r\n          \"value\": \"10\",\r\n          \"currency_code\": \"USD\"\r\n        }\r\n      }\r\n    }\r\n  ],\r\n  \"payment_preferences\": {\r\n    \"auto_bill_outstanding\": true,\r\n    \"setup_fee\": {\r\n      \"value\": \"10\",\r\n      \"currency_code\": \"USD\"\r\n    },\r\n    \"setup_fee_failure_action\": \"CONTINUE\",\r\n    \"payment_failure_threshold\": 3\r\n  },\r\n  \"taxes\": {\r\n    \"percentage\": \"10\",\r\n    \"inclusive\": false\r\n  }\r\n}",
  CURLOPT_HTTPHEADER => array(
    "authorization: Bearer A21AAJd7f6oo6_Inozxc4JfgLaPvnlU_-3kYw_8JdRLnjsJ-aiRe_ZgRaZWBnwd4Oh8WZvwBbvyI0QRHGY3pRVbWGgnV8kY1g",
    "cache-control: no-cache",
    "content-type: application/json",
    "postman-token: 4ed388a2-e0eb-39f2-a624-51291f549960",
    "prefer: return=representation"
  ),
));

$response = curl_exec($curl);
$err = curl_error($curl);
curl_close($curl);
echo $response;

我已通过上述 curl 请求成功接收到计划 ID。

 <script src="https://www.paypal.com/sdk/js?client-id=<client-id>&currency=USD&intent=subscription&commit=false&vault=true&disable-funding=credit,card"></script>

<script>
    paypal.Buttons({
        createSubscription: function() {
          return fetch('getplan.php', {
            method: 'post',
            headers: {
              'content-type': 'application/json'
            },
          }).then(function(res) {
            return res.json();
          }).then(function(data,actions) {
            return actions.subscription.create({
               'plan_id': data.id
            });
          });
        },
    onApprove: function(data, actions) {

    alert('You have successfully created subscription ' + data.subscriptionID);

  }
  }).render('#paypal-button');
</script>
<div id="paypal-button"></div>

但控制台给出错误“无法读取未定义的属性‘订阅’”。如果我在创建订阅函数时手动输入 plan_id（我创建的），它会给我错误：无法读取未定义的属性“订阅”。

请帮忙！

好的，发现你的问题了。 actions 未定义，因为您在错误的位置将其作为参数。

    createSubscription: function(data, actions) {
          return fetch('getplan.php', {
            method: 'post',
            headers: {
              'content-type': 'application/json'
            },
          }).then(function(res) {
            return res.json();
          }).then(function(serverData) {
            return actions.subscription.create({
               'plan_id': serverData.id
            });
          });
        },

这是一种奇怪的编码模式——如果你在 createSubscription 中对你的服务器进行提取，你也可以创建订阅服务器端（getsubscription.php 或其他）并返回订阅 ID 而不是而不是计划 ID。
