在 PHP 中使用 REST API 进行 Paypal 付款

Making Paypal payment using REST API in PHP(在 PHP 中使用 REST API 进行 Paypal 付款)

问题描述

我不清楚如何将此代码示例放入 PHP 的 CURL 结构中，特别是 -d 句柄.

I'm not clear how to put this code example into PHP's CURL structure, specifically, the -d handle.

curl -v https://api.sandbox.paypal.com/v1/payments/payment 
-H 'Content-Type:application/json' 
-H 'Authorization:Bearer EOjEJigcsRhdOgD7_76lPfrr45UfuI43zzNzTktUk1MK' 
-d '{
  "intent":"sale",
  "redirect_urls":{
    "return_url":"http://<return URL here>",
    "cancel_url":"http://<cancel URL here>"
  },
  "payer":{
    "payment_method":"paypal"
  },
  "transactions":[
    {
      "amount":{
        "total":"7.47",
        "currency":"USD"
      },
      "description":"This is the payment transaction description."
    }
  ]
}'

我已经使用了以下测试调用，但不知道如何将其扩展到上面的示例.

I've used the following test call ok, but don't know how to extend that to the example above.

curl_setopt($ch, CURLOPT_URL, "https://api.sandbox.paypal.com/v1/oauth2/token");
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
curl_setopt($ch, CURLOPT_USERPWD, $clientId.":".$secret);
curl_setopt($ch, CURLOPT_POSTFIELDS, "grant_type=client_credentials");

$result = curl_exec($ch);

if(empty($result))die("Error: No response.");
else
{
    $json = json_decode($result);
    print_r($json->access_token);
}

推荐答案

试试这个， -d 就是你要发布的数据.自定义标头使用 CURLOPT_HTTPHEADER 设置.

Try something like this, -d is the data you want to post. custom headers are set with CURLOPT_HTTPHEADER.

$data = '{
  "intent":"sale",
  "redirect_urls":{
    "return_url":"http://<return URL here>",
    "cancel_url":"http://<cancel URL here>"
  },
  "payer":{
    "payment_method":"paypal"
  },
  "transactions":[
    {
      "amount":{
        "total":"7.47",
        "currency":"USD"
      },
      "description":"This is the payment transaction description."
    }
  ]
}';

curl_setopt($ch, CURLOPT_URL, "https://api.sandbox.paypal.com/v1/payments/payment");
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data); 
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
  "Content-Type: application/json",
  "Authorization: Bearer EOjEJigcsRhdOgD7_76lPfrr45UfuI43zzNzTktUk1MK", 
  "Content-length: ".strlen($data))
);

看看这里的选项，http://php.net/手册/en/function.curl-setopt.php设置 curl_setopt($ch, CURLOPT_HEADER, false);例如，如果您不需要返回标头.

Have a look at the options here, http://php.net/manual/en/function.curl-setopt.php Set curl_setopt($ch, CURLOPT_HEADER, false); for example if you dont need the headers returned.
