$url = trim("https://svcs.sandbox.paypal.com/AdaptiveAccounts/GetVerifiedStatus");  //set PayPal Endpoint to sandbox
$API_UserName = "XXXXXXXXXXXXXXXXXXX"; 
$API_Password = "XXXXXXXXXXXXXXXXXXX"; 
$API_Signature = "XXXXXXXXXXXXXXXXXX"; 
$API_AppID = "APP-80W284485P519543T"; 
$API_RequestFormat = "NV";
$API_ResponseFormat = "NV";
$bodyparams = array ("requestEnvelope.errorLanguage" => "en_US",
"emailAddress" =>"[e-mail]",
"firstName" =>"Kunal",
"lastName" =>"Mahajan",
"matchCriteria" => "NAME"
);
$body_data = http_build_query($bodyparams, "", chr(38));

$ctx = stream_context_create($params);  //create stream context
$fp = @fopen($url, "r", false, $ctx);   //open the stream and send request
$response = stream_get_contents($fp);   //get response
if ($response === false){
throw new Exception("php error message = " . "$php_errormsg");

fclose($fp);    //close the stream

Answer 1

尝试使用

$response = file_get_contents($url, false, $ctx);

而不是

$fp = @fopen($url, "r", false, $ctx);   //open the stream and send request
$response = stream_get_contents($fp);   //get response

并更改此设置：

$params = array("http" => array( 
"method" => "POST",
"content" => $body_data,
"header" => "X-PAYPAL-SECURITY-USERID:     " . $API_UserName . "rn" .
"X-PAYPAL-SECURITY-SIGNATURE:  " . $API_Signature . "rn" .
"X-PAYPAL-SECURITY-PASSWORD:   " . $API_Password . "rn" .
"X-PAYPAL-APPLICATION-ID:      " . $API_AppID . "rn" .
"X-PAYPAL-REQUEST-DATA-FORMAT: " . $API_RequestFormat . "rn" .
"X-PAYPAL-RESPONSE-DATA-FORMAT:" . $API_ResponseFormat . "rn" 
));

对此：

$params = array("http" => array( 
"method" => "POST",
"content" => $body_data,
"header" =>
"X-PAYPAL-SECURIY-USERID:     " . $API_UserName . "rn" .
"X-PAYPAL-SECURITY-SIGNATURE:  " . $API_Signature . "rn" .
"X-PAYPAL-SECURITY-PASSWORD:   " . $API_Password . "rn" .
"X-PAYPAL-APPLICATION-ID:      " . $API_AppID . "rn" .
"X-PAYPAL-REQUEST-DATA-FORMAT: " . $API_RequestFormat . "rn" .
"X-PAYPAL-RESPONSE-DATA-FORMAT:" . $API_ResponseFormat . "rn" .
"Content-type: application/x-www-form-urlencodedrn"
));
