cURL传递参数-PHP-Laravel

Question

I am using this cURL function to send a set of data that has to be received by the api. However the api receives null.

public static function httpPost($url,$type,$params)
{
    $postData = '';

    foreach ($params as $k => $v) {
        $postData .= $k . '=' . $v . '&';
    }
    $postData = rtrim($postData, '&');

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_SAFE_UPLOAD, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $postData);
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, $type);
    $output = curl_exec($ch);

    curl_close($ch);
    return $output;

}

I have tried outputting the data before sending and it shows correct data. The other curl part works. Any idea why data is not being sent through curl?

Since you do not need to use POST, unset that curl option and use PHP http_builder to build the URL

public static function httpPost($url,$type,$params)
{
    // Clean URL + append "?" at the end of URL + append the query
    $url = rtrim($url,"?") . "?" . http_build_query($params);

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_SAFE_UPLOAD, true);
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, $type);
    $output = curl_exec($ch);

    curl_close($ch);
    return $output;

}
