爲什麼PHP + curl，HTTP POST請求返回null？

Question

我很困惑，爲什麼$響應不返回任何東西，我是新來的捲曲請大家幫忙，

$post = [ 
     'AreaCode' => '02', 
     'PhoneNumber' => '33312733', 
     'InquiryBy' => 'telephone', 
    ]; 

    $ch = curl_init(); 
    curl_setopt($ch, CURLOPT_URL, 'https://billing.te.eg/api/Account/Inquiry'); 
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0); 
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0); 
    curl_setopt($ch, CURLOPT_POSTFIELDS, $post); 
    curl_setopt($ch, CURLOPT_HTTPHEADER, array(
     'Content-Type:application/json', 
     'Access-Control-Allow-Origin: *', 
    )); 
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10); 
    curl_setopt($ch, CURLOPT_TIMEOUT, 10); 
    $httpCode = curl_getinfo($ch , CURLINFO_HTTP_CODE); 
    $response = curl_exec($ch); 
    if ($response === false) $response = curl_error($ch); 
    echo stripslashes($response); 
    curl_close($ch);

Answer 1

請添加以下行來定義請求類型（GET/POST/..）然後嘗試：

curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST"); 

Answer 2

下載cacert.pem文件保存在根目錄下並設置curl opti並嘗試

http://curl.haxx.se/ca/cacert.pem

curl_setopt ($h, CURLOPT_CAINFO, base_path()."/cacert.pem");
