带有 PHP 和 cURL 的 Paypal API [英] Paypal API with PHP and cURL

问题描述

我正在尝试按照 Paypal API 文档所述的第一次调用".这是我遵循的示例:

I'm attempting "the first call" as outlined by the Paypal API documentation. This is the example provided that I'm following:

curl https://api.sandbox.paypal.com/v1/oauth2/token 
 -H "Accept: application/json" 
 -H "Accept-Language: en_US" 
 -u "EOJ2S-Z6OoN_le_KS1d75wsZ6y0SFdVsY9183IvxFyZp:EClusMEUk8e9ihI7ZdVLF5cZ6y0SFdVsY9183IvxFyZp" 
 -d "grant_type=client_credentials"

我已经在 PHP 中构建了一个 curl 实例，除了最后一个之外，还有上述所有标头.-d 标志在 PHP 中转换为 curl 选项是什么?据我所知，那里几乎没有解释.我设法将 -u 推断为 CURLOPT_USERPWD.

I have constructed a curl instance in PHP with all the above headers apart from the last one. What does a -d flag convert to as a curl option in PHP? There is little explanation there as far as I can tell. I managed to deduce -u as CURLOPT_USERPWD.

推荐答案

经过一番周密的摸索，我将开发人员的部分内容与其他问题拼凑在一起.我使用以下代码成功获得了访问令牌:

Having a good trawl around I pieced together parts from developers with other problems. I successfully gained my access token using the following code:

<?php

$ch = curl_init();
$clientId = "myId";
$secret = "mySecret";

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);
}

curl_close($ch);

?>
