因此，经过大量搜索，我终于能够使用PHP cURL成功获得我的Paypal访问令牌。现在我正试图根据交易id检索交易详细信息。到目前为止，我认为我已经得到了正确的调用URL，但我认为我的帖子数据格式可能不正确。使用的代码如下：
<?php
//this function is for handling post call requests
function make_post_call($url, $postdata) {
global $token;
$curl = curl_init($url);
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, true);
curl_setopt($curl, CURLOPT_SSLVERSION , 6);
curl_setopt($curl, CURLOPT_HEADER, false);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_HTTPHEADER, array(
'Authorization: Bearer '.$token,
'Accept: application/json',
'Content-Type: application/json'
));
curl_setopt($curl, CURLOPT_POSTFIELDS, $postdata);
$response = curl_exec( $curl );
print_r($response); //IM NOW RECEIVING OUTPUT, however symbols are now being replaced by placeholders such as '%40', how can i prevent this?
if (empty($response)) {
die(curl_error($curl)); //close due to error
curl_close($curl);
} else {
$info = curl_getinfo($curl);
echo "Time took: " . $info['total_time']*1000 . "ms'n";
curl_close($curl); // close cURL handler
if($info['http_code'] != 200 && $info['http_code'] != 201 ) {
echo "Received error: " . $info['http_code']. "'n";
echo "Raw response:".$response."'n";
die();
}
}
// Convert the result from JSON format to a PHP array
$jsonResponse = json_decode($response, TRUE);
return $jsonResponse;
}
$token = get_access_token($url,$postArgs); //works and returns a valid access token
//This is the URL for the call
$url = 'https://api-3t.sandbox.paypal.com/nvp';
//This is the data to be sent in the call
$postdata = array(
'USER' => 'peoplesroewrwwsg_api1.outlook.com',
'PWD' => 'KR2TVKHGDSHSNDJ6E2',
'SIGNATURE' => 'AFcWxV21C7fdFHSGGSDGD51G0BJYUWOCSyjUAKPPGs',
'METHOD' => 'GetTransactionDetails',
'VERSION' => '123',
'TransactionID' => '1RE953245246192109'
);
$postdata = http_build_query($postdata);
//$postdata = json_encode($postdata); //Is this the correct way of formatting?
$transactionInfo = make_post_call($url, $postdata); //get transaction details NOT WORKING
print_r($transactionInfo); //does not print anything
?>
我没有收到任何cURL错误，所以我认为问题要么是我发送的数据，要么是我如何格式化它。
关于如何做到这一点的breif Paypal指南可以在这里找到->https://developer.paypal.com/docs/classic/express-checkout/gs_transaction/#tryit然而，它是用cURL而不是PHP cURL扩展编写的，所以我不确定我是否正确发送了数据。

非常感谢任何有关数据格式的指导或任何其他建议！

现在，当我在cURL语句执行后立即打印结果时，我收到的信息如下：
RECEIVERID=GN7SRQEGEREASDV9BQU&EMAIL=peoplesrobotiblabal%40outlook%2ecom&PAYERID=JC5RWUUKWGDFYJYY&PAYERSTATUS=verified&COUNTRYCODE=US&SHIPTONAME=Jane%20Smurf...
可以看出，一些符号（如句点）正被占位符（如"%40"）所取代。这是什么原因？是因为我在等待JSON响应吗？
要从PHP数组构建http查询字符串，可以使用PHP http_build_query()。示例：
$array = ['username' => 'John', 'password' => '123456abc'];
$postdata = http_build_query($array);
您提到的符号是特殊字符的url编码形式。Http请求将要求对查询字符串进行url编码。%40是@的url编码形式。如果将来需要对url编码的字符串进行编码/解码，可以使用rawurldecode()、rawurlencode()、urlencode()和urldecode()。
用于解析PAYPAL NVP API的响应。您可以使用parse_str()。示例1:
$response = 'status=success&code=02';
parse_str($response, $response_array);
//$response_array will contain the $response as array
示例2:
$response = 'status=success&code=02';
parse_str($response);
//this will display success
echo $status;
//this will display 02
echo $code;
<?php
function get_transaction_details( $transaction_id ) {
$api_request = 'USER=' . urlencode( 'api_username' )
. '&PWD=' . urlencode( 'api_password' )
. '&SIGNATURE=' . urlencode( 'api_signature' )
. '&VERSION=76.0'
. '&METHOD=GetTransactionDetails'
. '&TransactionID=' . $transaction_id;
$ch = curl_init();
curl_setopt( $ch, CURLOPT_URL, 'https://api-3t.sandbox.paypal.com/nvp' ); // For live transactions, change to 'https://api-3t.paypal.com/nvp'
curl_setopt( $ch, CURLOPT_VERBOSE, 1 );
// Uncomment these to turn off server and peer verification
// curl_setopt( $ch, CURLOPT_SSL_VERIFYPEER, FALSE );
// curl_setopt( $ch, CURLOPT_SSL_VERIFYHOST, FALSE );
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, 1 );
curl_setopt( $ch, CURLOPT_POST, 1 );
// Set the API parameters for this transaction
curl_setopt( $ch, CURLOPT_POSTFIELDS, $api_request );
// Request response from PayPal
$response = curl_exec( $ch );
// print_r($response);
// If no response was received from PayPal there is no point parsing the response
if( ! $response )
die( 'Calling PayPal to change_subscription_status failed: ' . curl_error( $ch ) . '(' . curl_errno( $ch ) . ')' );
curl_close( $ch );
// An associative array is more usable than a parameter string
parse_str( $response, $parsed_response );
return $parsed_response;
}
$response = get_transaction_details('transaction_id');
echo "<pre>"; print_r($response);
?>
从cURL 接收信息
$str = RECEIVERID=GN7SRQEGEREASDV9BQU&EMAIL=peoplesrobotiblabal%40outlook%2ecom&PAYERID=JC5RWUUKWGDFYJYY&PAYERSTATUS=verified&COUNTRYCODE=US&SHIPTONAME=Jane%20Smurf...
请使用parse_str("$str"); // add your value here, it will give you proper data format
