问题描述

我使用以下代码获取响应来自 paypal有关付款：
 
 
 $ header =   POST / cgi-bin / webscr HTTP / 1.1 \\\\ n;  //   HTTP POST请求 
 $ header。=   Content-Type：application / x-www-form-urlencoded\r\\\
; 
 $ header。=  主持人：www.sandbox.paypal.com \\\\ n< /跨度>; 
 $ header。=   Content-Length：。 strlen（$ req）。   \\\\ n; 
 $ header。=  连接：关闭\\\\\ n /跨度>; 
 
 $ fp = fsockopen（'  ssl：//www.sandbox.paypal.com' ， 443 ，$ errno，$ errstr， 30 ）; 
 var_dump（fputs（$ fp，$ header。$ req））; 
 $ res = stream_get_contents（$ fp， 1024 ）; 
 
我在 $ res 中收到的的回复是：

 As远 as 我明白我应该获取  已验证但我无法获取。任何人都可以指出 out 问题是？ 
 
 我尝试了什么： 
 
我根据中的答案更改了我的代码 stackoverflow关于同一个问题。最初当我使用代码时，我没有得到任何东西在响应中，它为NULL：
 
 fputs（$ fp，$ header。$ req）; 
  while （！feof（$ fp））{
 $ res = fgets（$ fp， 1024 ）; 
} 

解决方案

header = POST / cgi-bin / webscr HTTP / 1.1 \\\\ n; // HTTP POST请求

header。= Content-Type：application / x-www-form-urlencoded\r\ n;

header。= 主持人：www.sandbox.paypal.com\\\\ N;

I am using the following code to get response from paypal regarding payment:
 

    $header = "POST /cgi-bin/webscr HTTP/1.1\r\n"; // HTTP POST request
    $header.= "Content-Type: application/x-www-form-urlencoded\r\n";
    $header.= "Host: www.sandbox.paypal.com\r\n";
    $header.= "Content-Length: " . strlen($req) . "\r\n";
    $header.= "Connection: Close\r\n\r\n";
    
    $fp = fsockopen ('ssl://www.sandbox.paypal.com', 443, $errno, $errstr, 30);
    var_dump(fputs($fp, $header . $req));
    $res = stream_get_contents($fp, 1024); 	

The response that I am receiving in $res is:

    HTTP/1.1 200 OK

As far as I understand I should get "VERIFIED" but I am unable to get that. Can anyone point out what the problem is?

What I have tried:

I changed my code according to an answer in stackoverflow regarding the same question. Initially when I was using below code, I wasn't getting anything in response, it was NULL:

    fputs($fp, $header . $req);
    while (!feof($fp)) {
                    $res = fgets ($fp, 1024); 
    }

解决方案

header = "POST /cgi-bin/webscr HTTP/1.1\r\n"; // HTTP POST request

header.= "Content-Type: application/x-www-form-urlencoded\r\n";

header.= "Host: www.sandbox.paypal.com\r\n";
