【问题标题】：Paypal Adaptive Api payment error failed to open stream: HTTP request failed! HTTP/1.0 400 Bad RequestPaypal Adaptive Api payment error failed to open stream: HTTP 请求失败！ HTTP/1.0 400 错误请求
【发布时间】：2016-01-22 07:24:01
【问题描述】：

我正在使用自适应网址，例如

$url = trim("https://svcs.".$sandbox."paypal.com/AdaptivePayments/Pay");

我收到此错误消息：||php 错误消息 = fopen(https://svcs.sandbox.paypal.com/AdaptivePayments/Pay): 无法打开流：HTTP 请求失败！ HTTP/1.0 400 错误请求 ||

【问题讨论】：

我在哪里使用 urlencode() 函数。我收到新错误：- fopen（https%3A%2F%2Fsvcs.sandbox.paypal.com%2FAdaptivePayments%2FPay）：无法打开流：没有这样的文件或目录
urlencode("svcs.".$sandbox."paypal.com/AdaptivePayments/…);

标签： php paypal

【解决方案1】：

用urlencode()试试这个：

$url = urlencode("https://svcs.".$sandbox."paypal.com/AdaptivePayments/Pay");

同样的错误 fopen(https%3A%2F%2Fsvcs.sandbox.paypal.com%2FAdaptivePayments%2FPay)：无法打开流：没有这样的文件或目录
$params = array("http" => array( "method" => "POST", "content" => $body_data, "header" => "X-PAYPAL-SECURITY-USERID : " . $API_UserName . "\r\n" . "X-PAYPAL-SECURITY-SIGNATURE: " . $API_Signature . "\r\n" . "X-PAYPAL-SECURITY-PASSWORD: " . $API_Password . "\ r\n" . "X-PAYPAL-APPLICATION-ID: " . $API_AppID . "\r\n" . "X-PAYPAL-REQUEST-DATA-FORMAT: " . $API_RequestFormat . "\r\n" . " X-PAYPAL-RESPONSE-DATA-FORMAT: " . $API_ResponseFormat . "\r\n". "X-PAYPAL-DEVICE-IPADDRESS: " . $PROXY_HOST . "\r\n" ));
@ramesh: 试试 file_get_contents('svc'.$sandbox.'paypal.com/AdaptivePayments/Pay');
我使用 $ctx = stream_context_create($params);然后 $response = stream_get_contents($fp);
