邮递员请求有效，但CURL发布获得无效结果-PHP

如何解决邮递员请求有效，但CURL发布获得无效结果-PHP

我搜索了很多帖子，但是我认为它与stackoverflow上的其他帖子相比有所不同。我正在尝试使用this API获得cloudvideo.tv流链接。我将应用托管在heroku上，该应用在邮递员中运行良好，如下图所示，并提取了链接。

但是使用curl方法从cpanel中返回mp4链接，但是不起作用。似乎有些令牌或cookie丢失了，或者idk可能存在IP问题。

这是脚本文件：

<?php

/**
 * Getting direct cloudvideo URL 
 * using node-urlresolver-api API by @lscofield
 * This script is only tested with cloudvideo embed links
 */

// cloudvideo.tv test url 
// cloudvideo extraction work only with embed url
// You can test with another link if this link go down
$url = 'https://cloudvideo.tv/embed-935a86z3wfbw.html';
$agent = 'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1)';

// Function to get the client IP address
function get_client_ip() {
$ipaddress = '';
if (isset($_SERVER['HTTP_CLIENT_IP']))
    $ipaddress = $_SERVER['HTTP_CLIENT_IP'];
else if(isset($_SERVER['HTTP_X_FORWARDED_FOR']))
    $ipaddress = $_SERVER['HTTP_X_FORWARDED_FOR'];
else if(isset($_SERVER['HTTP_X_FORWARDED']))
    $ipaddress = $_SERVER['HTTP_X_FORWARDED'];
else if(isset($_SERVER['HTTP_FORWARDED_FOR']))
    $ipaddress = $_SERVER['HTTP_FORWARDED_FOR'];
else if(isset($_SERVER['HTTP_FORWARDED']))
    $ipaddress = $_SERVER['HTTP_FORWARDED'];
else if(isset($_SERVER['REMOTE_ADDR']))
    $ipaddress = $_SERVER['REMOTE_ADDR'];
else
    $ipaddress = 'UNKNOWN';
return $ipaddress;
}

$client_ip = get_client_ip();



// Create curl instance (GET)
$ch = curl_init();
//Set the URL that you want to GET by using the CURLOPT_URL option.
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_USERAGENT,$agent);
//Set CURLOPT_RETURNTRANSFER so that the content is returned as a variable.
curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
//Set CURLOPT_FOLLOWLOCATION to false to follow redirects.
curl_setopt($ch,CURLOPT_FOLLOWLOCATION,false);
// Set referer for mixdrop request 
curl_setopt($ch,CURLOPT_REFERER,$url);

//Execute the request.
$html = curl_exec($ch);
//Close the cURL handle.
curl_close($ch);

// Encode the html code to base64
$html = base64_encode($html);
$host = "cloudvideo"; // in this case
$api_endpoint = "https://videoapilower.herokuapp.com/$host";
// Prepare POST params
// Prepare auth param
$auth = '{"auth":"","skk":"AIzaSyBCnxpXl8DlT-J7mTff38xTDZ-speJOvKY"}';
// Encode auth to base64
$auth = base64_encode($auth);
$params = array(
"source" => $html,"auth" => $auth
);

$params = json_encode($params);
// Create curl instance (POST) to get direct
// URL with API

$ch = curl_init($api_endpoint);
curl_setopt($ch,$agent);

curl_setopt($ch,true);
curl_setopt($ch,CURLINFO_HEADER_OUT,CURLOPT_POST,CURLOPT_POSTFIELDS,$params);
// Set HTTP Header for POST request 
curl_setopt(
$ch,CURLOPT_HTTPHEADER,array(
    'Content-Type: application/json','Content-Length: ' . strlen($params),"Access-Control-Allow-Headers: Origin,X-Requested-With,Content-Type,Accept","Access-Control-Allow-Origin: *","Connection: keep-alive","REMOTE_ADDR: $client_ip","HTTP_X_FORWARDED_FOR: $client_ip","X-CLIENT-REMOTE-IP: $client_ip","X-Real-IP: $client_ip","X-Forwarded-For: $client_ip"
)
);
// Submit the POST request
$result = curl_exec($ch);
curl_close($ch);


if ($result) {
$result = json_decode($result);
echo $result->url;
} else {
}
?>

我尝试了CURLOPT HTTPHEADER，客户端ip和用户代理以及curl请求，但没有成功。

CURLOPT_HTTPHEADER,array
    (
    'Content-Type: application/json',"X-Forwarded-For: $client_ip"
)

这是未经修改的php脚本FILE。 我不确定我的方法缺少什么或有什么问题。请告知我在哪里做错了。
