PHP - Curl Request Append Response

A HTTP request is made to the server, Slim creates a Request and Response object, content in the Request is sent to another server using cURL via Guzzle, Guzzle returns its own Response,  and content from Guzzle's response must be returned by the original Slim response.

Would you recommend white-listing or black-listing response headers, and which specific headers?

Similarly, would you recommend white-listing or black-listing the request headers sent via cURL, and which specific headers?

Thanks

<?php
use Psr\Http\Message\ResponseInterface as Response;
use GuzzleHttp\Psr7\Response as CurlResponse;

class ApiResponder
{
    public function delete(Response $httpResponse, CurlResponse $curlResponse) {
        return $this->proxy($httpResponse, $curlResponse);
    }
    //other public methods...

    private function proxy(Response $httpResponse, CurlResponse $curlResponse) {
        foreach($this->getResponseHeaders($curlResponse) as $name=>$value) {
            $httpResponse=$httpResponse->withHeader($name, $value);
        }
        return $httpResponse->withBody($curlResponse->getBody())->withStatus($curlResponse->getStatusCode());
    }

    private function getResponseHeaders(Response $httpResponse):array
    {
        //Blacklist headers which should be returned to original client.  TBD whether I should whitelist headers instead.
        $blacklist=['Date'=>null, 'Server'=>null, 'X-Powered-By'=>null, 'Access-Control-Allow-Origin'=>null, 'Access-Control-Allow-Methods'=>null, 'Access-Control-Allow-Headers'=>null, 'Set-Cookie'=>null];
        return array_diff_key($curlResponse->getHeaders(), $blacklist);
    }

    /**
    * This method doesn't really exist in this class, but is just included to show which headers I am forwarding in the cURL request.
    */
    private function getRequestHeaders($clientRequest):array
    {
        $whitelist=['connection'=>null,'accept'=>null,'accept-encoding'=>null,'accept-language'=>null,'content-type'=>null,'content-length'=>null];
        return array_intersect_key($clientRequest->getHeaders(), $whitelist);
    }
}

 

I have an application which receives multiple requests at once and it advantageous to process them as a group.

I am thinking I should be doing something like the following, however, as I just came up with it on my own, would appreciate a critique.  Is this a common design pattern or should I be doing something differently?  Note that I have three questions asking specific questions in the below code (look for the comments with question marks).

Thanks

I need to make my client's site distinguish among different tabs in the same browser. (See http://www.phpfreaks.com/forums/index.php?topic=357772.0 for background.)

I create a tab ID when the user first visits the site in a particular tab, and I'm passing it from page to page as a parameter. This seems to be the only way to do what I need.

The tab ID is always passed through POST so that the user won't see it. If it were visible, users could make trouble (or more likely get in trouble) by adding or removing the ID themselves.

This is not simple where a page is loaded by a hyperlink. The anchor tag passes parameters via GET, period.

The solution I found is to link to a script named post.php, which takes the real link target and the tab ID as parameters, sends the browser a form that passes the tab ID to the real link target via POST, and auto-submits the form via JavaScript.

This works, but it requires two round trips to the browser to load a page. It's also a pain to code.

Is there a more efficient way to do this... perhaps a way to make the server send the browser a POST response, even though it made a GET request?

If it matters, the server is Apache 2.x.

Hi, I'm posting a form using curl:

Code: [Select]
<?php

//create the final string to be posted using implode()
$post_str = implode ('&', $post_items);
  
//Initialize cURL and connect to the remote URL 
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://leads..html' );

//Instruct cURL to do a regular HTTP POST
curl_setopt($ch, CURLOPT_POST, TRUE);

//Specify the data which is to be posted
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_str);

//Tell curl_exec to return the response output as a string
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);

//Follow 302 redirect
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);  

// Timeout in seconds
curl_setopt($ch, CURLOPT_TIMEOUT, 30);

//verify https
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);

//Execute the cURL session
$response = curl_exec($ch );

//Close cURL session and file
curl_close($ch);

echo $response;

$resp = explode("\n\r\n", $response);
$header = explode("\n", $resp[0]);

echo "<pre>";
print_r($header);
echo "</pre>";

?>

The response is:

success:  https://www-somesite.html

or

Array
(
    => success: https://www-somesite.html
)

My question is how to get the returned URL and redirect the user to it?

Probably easy but seems to be beyond my very limited php knowledge.

Thanks.

I have been using PHP CURL to obtain stock data... The URL is   https://trade.plus50...ntName=Facebook     Essentially, it is supposed to return date, time, and price of stock tick data   But it returns stuff like "HrCy/h6wsw4esLL+HrCzDh6wsw4esLMOHrCzDh6wsu4esLLeHrCy7h6wsu4esLL"   So... I would like to know, what is this format, and how do I decode it?
