我有 PHP 代碼可以使用不同的資料對同一個 URL 執行 2 個 Curl 呼叫。它有效，但第一次和第二次之間有一些滯后（幾秒鐘）。我看過 curl multi 但無法弄清楚如何將它用于 JSON 陣列。請幫忙？
<?php
$data = array("epic" => $epic, "expiry" => "DFB");
$data_string = json_encode($data);
$headers = array(
'Content-Type: application/json; charset=UTF-8',
'Accept: application/json; charset=UTF-8',
'X-IG-API-KEY: '.$xapikey,
'Version: 1',
'X-SECURITY-TOKEN: '.$_SESSION['api_xtoken'],
'CST: ' .$_SESSION['api_cst'],
'_method: DELETE',
);
$ch = curl_init('' . $trading_url . '');
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS,$data_string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
$result = curl_exec($ch);
$data2 = array("currencyCode" => "GBP", "direction" => $tv_direction);
$data_string2 = json_encode($data2);
$ch2 = curl_init('' . $trading_url . '');
curl_setopt($ch2, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch2, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch2, CURLOPT_VERBOSE, 1);
curl_setopt($ch2, CURLOPT_HEADER, 1);
curl_setopt($ch2, CURLOPT_POSTFIELDS,$data_string2);
curl_setopt($ch2, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch2, CURLOPT_HTTPHEADER, $headers2);
$result2 = curl_exec($ch2);

您打開 curl 連接兩次，一旦請求完成，您還沒有關閉連接，您需要關閉連接
可以嘗試這樣的事情
$data_string = json_encode($data);
$headers = array(
'Content-Type: application/json; charset=UTF-8',
'Accept: application/json; charset=UTF-8',
'X-IG-API-KEY: '.$xapikey,
'Version: 1',
'X-SECURITY-TOKEN: '.$_SESSION['api_xtoken'],
'CST: ' .$_SESSION['api_cst'],
'_method: DELETE',
);
$ch = curl_init('' . $trading_url . '');
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS,$data_string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
$result = curl_exec($ch);
$data2 = array("currencyCode" => "GBP", "direction" => $tv_direction);
$data_string2 = json_encode($data2);
curl_setopt($ch, CURLOPT_POSTFIELDS,$data_string2);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers2);
$result2 = curl_exec($ch);
curl_close($ch);

您可以使用同時啟動它們stream_socket_client()
您也可以使用 stream_socket_client() 來呼叫您自己的兩個 php 腳本，其中每個 curl 請求都在每個腳本中。然后，您使用您自己的腳本使用的 url
呼叫您的兩個腳本。stream_socket_client()
使用套接字并不簡單，所以我附上了我 10 年前寫的一些代碼。我記得花了一兩天才能讓它作業
該腳本的作用是使用 W3C CSS 和 HTML 驗證器工具和網頁速度測驗來驗證網頁，以評估網頁的設計情況。與串行發出請求相比，并行呼叫它們顯著減少了時間。
您可能想要使用更新的用戶代理。
