Paypal API with PHP and cURL
提问by Lee
I'm attempting "the first call" as outlined by the Paypal API documentation. This is the example provided that I'm following:
我正在尝试 Paypal API 文档中概述的“第一次调用”。这是我遵循的示例：
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"
I have constructed a curl instance in PHP with all the above headers apart from the last one. What does a -dflag convert to as a curl option in PHP? There is little explanation there as far as I can tell. I managed to deduce -uas CURLOPT_USERPWD.
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。-dPHP中的标志转换为 curl 选项是什么？据我所知，那里几乎没有解释。我设法推断-u为CURLOPT_USERPWD.

Having a good trawl around I pieced together parts from developers with other problems. I successfully gained my access token using the following code:
进行了良好的搜索，我将开发人员的部分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：
<?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);
?>

@Lee point the right way but if u are using and old php version it wont work. But Lee version will not show up the error. Use these instead, i only add the error part to see what is going on.
@Lee 指出正确的方法，但如果您使用的是旧的 php 版本，它将无法正常工作。但李版不会显示错误。改用这些，我只添加错误部分以查看发生了什么。
$ch = curl_init();
$clientId = "";
$secret = "";
curl_setopt($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);
$err = curl_error($ch);
$access_token="";
if ($err) {
echo "cURL Error #:" . $err;
}
else
{
$json = json_decode($result);
// print_r($json->access_token);
$access_token = $json->access_token;
}
If u are having and old PHP version it is posible it wont work and it will show this error:
如果您使用的是旧 PHP 版本，则可能无法正常工作，并且会显示以下错误：
cURL Error #:error:14077410:SSL routines:SSL23_GET_SERVER_HELLO:sslv3 alert handshake failure
Just stack overflow it! Here they discuss the problem

JSONand US Englishappear to be the Defaults, but to be in perfect compliance, add the following line:
JSON和美国英语似乎是Defaults，但要完全符合要求，请添加以下行：
curl_setopt($ch, CURLOPT_HTTPHEADER, "Accept: application/json, Accept-Language: en_US");
