php，未找到 HTTP_REFERER

Question

您好，我正在尝试连接以将我的表单集成到支付提供商，但我收到不允许的 URL，结果发现未找到 HTTP_REFERER..

#the following function performs a HTTP Post and returns the whole response
function pullpage( $host, $usepath, $postdata = "" ) {

# open socket to filehandle(epdq encryption cgi)
 $fp = fsockopen( $host, 80, &$errno, &$errstr, 60 );

#check that the socket has been opened successfully
 if( !$fp ) {
    print "$errstr ($errno)<br>\n";
 }
 else {

    #write the data to the encryption cgi
    fputs( $fp, "POST $usepath HTTP/1.0\n");
    $strlength = strlen( $postdata );
    fputs( $fp, "Content-type: application/x-www-form-urlencoded\n" );
    fputs( $fp, "Content-length: ".$strlength."\n\n" );
    fputs( $fp, $postdata."\n\n" );

    #clear the response data
   $output = "";


    #read the response from the remote cgi 
    #while content exists, keep retrieving document in 1K chunks
    while( !feof( $fp ) ) {
        $output .= fgets( $fp, 1024);
    }

    #close the socket connection
    fclose( $fp);
 }

#return the response
 return $output;
}

#define the remote cgi in readiness to call pullpage function 
$server="secure2.epdq.co.uk";
$url="/cgi-bin/CcxBarclaysEpdqEncTool.e";

#the following parameters have been obtained earlier in the merchant's webstore
#clientid, passphrase, oid, currencycode, total
$params="clientid=xxx";
$params.="&password=xxxx";
$params.="&oid=xxxx";
$params.="&chargetype=Auth";
$params.="&currencycode=826";
$params.="&total=120";

#perform the HTTP Post
$response = pullpage( $server,$url,$params );

#split the response into separate lines
$response_lines=explode("\n",$response);

#for each line in the response check for the presence of the string 'epdqdata'
#this line contains the encrypted string
$response_line_count=count($response_lines);
for ($i=0;$i<$response_line_count;$i++){
    if (preg_match('/epdqdata/',$response_lines[$i])){
        $strEPDQ=$response_lines[$i];
    }
}

有人可以帮忙吗？

Answer 1

我认为其他一些帖子直接处理您所看到的问题，但是，我确实想建议您研究使用 CURL (http://php.net/manual/en/book.curl.php) 来了解您想要执行的操作，而不是手动打开套接字连接。您的支付提供商甚至可能有一些 PHP 代码示例。通常，这是处理网关通信的更好方法，并且具有更大的灵活性。

如果您与多个网关集成，这将特别方便，因为大多数网关都有 CURL 代码示例，并且您将来会发现它的其他用途。

编辑：

甚至比 PHP 手册更好 - 该网站更清楚地说明了如何使用它，包括身份验证例程、传递帖子变量等，并附有示例：

Answer 2

fputs( $fp, "Referer: ".$somereferer."\n" );

Answer 3

我认为您忘记了 Host: 标头。

但是，有比打开套接字并实现您自己的 HTTP 客户端更好的方法来通过 HTTP 发布内容。尝试curl。
