How to stop cURL from formatting URL string in PHP-CodePudding

I am trying to parse an API request with cURL, however I've just discovered (with curl_getinfo) after hours of debugging that my URL is being formatted - specifically special characters such as / and ?.

This is being caused by the fact that I am causing urlencode($apiQuery) which formats the url to remove whitespaces, but incidentally causes issues for the entire url.

I am trying to write this in PHP, and have set my cURL request as follows:

$apiQuery = 'api.server.com/v0/Accounts/USER/INSTRUMENT?channels=all&start=2022-10-30 21:00:00';

$headers = array(
    'Accept: application/json',
    'Content-Type: application/json',
);

$c = curl_init();
curl_setopt($c, CURLOPT_URL, urlencode($apiQuery));
curl_setopt($c, CURLOPT_HTTPHEADER, $headers);
curl_setopt($c, CURLOPT_HEADER, 0);
curl_setopt( $c , CURLOPT_RETURNTRANSFER, true);
curl_setopt( $c , CURLOPT_SSL_VERIFYPEER, false);
curl_setopt( $c , CURLOPT_SSL_VERIFYHOST, false);
curl_setopt( $c , CURLOPT_TIMEOUT, 50000); // 50 sec

$resultA = curl_exec($c);

print_r(curl_getinfo($c));

where $resultA returns nothing, and curl_getinfo($c) returns:

Array
(
    [url] => HTTP://api.server.com/v0/Accounts/USER/INSTRUMENT?channels=all&start=2022-10-30 21:00:00/

    [http_code] => 0

    [redirect_url] =>
    [primary_ip] =>
    [certinfo] => Array
        (
        )

    [primary_port] => 0
    [local_ip] =>
    [local_port] => 0
)

CodePudding user response：

I would suggest to split the $apiQuery string:

$apiQuery = 'http://api.server.com/v0/Accounts';

$apiQuery .= '/' . urlencode($user);
$apiQuery .= '/' . urlencode($instrument);
$apiQuery .= '?';

$apiQuery .= http_build_query([
    'channels' => 'all',
    'start' => '2022-10-30 21:00:00',
]);

http_build_query also url escapes your params.
