cURL 錯誤 #：無法在 php 中連接到主機

Question

我嘗試調用此 api 但出現錯誤

cURL Error #:couldn't connect to host

我試試這個代碼

    <?php
$url = 'http://134.255.218.101:3002/ext/getaddress/GeHSBSKg5kav6vy6neQB5XsZ29zsNRyqeb';
$curl = curl_init();

curl_setopt_array($curl, array(
 CURLOPT_URL => 'http://134.255.218.101:3002/ext/getaddress/GeHSBSKg5kav6vy6neQB5XsZ29zsNRyqeb',
 CURLOPT_RETURNTRANSFER => true,
 CURLOPT_HTTPHEADER => array(
   "accept: application/json",
   "cache-control: no-cache",
   "content-type: application/json"
 ),
));

echo $response = curl_exec($curl);
$err = curl_error($curl);

curl_close($curl);

if ($err) {
 echo "cURL Error #:" . $err;
} else {
 echo $response;
}  
?>

代理服務器有問題...？

我如何在 php 中解決它

Answer 1

可能是網絡問題或其他問題，Curl 非常適合閱讀我用您的代碼嘗試過的網址，並且可以提供完美的結果。

檢查這個，

<?php
$url [![enter image description here][1]][1]='http://134.255.218.101:3002/ext/getaddress/GeHSBSKg5kav6vy6neQB5XsZ29zsNR
yqeb';
$curl = curl_init();

curl_setopt_array($curl, array(
CURLOPT_URL => $url,
CURLOPT_RETURNTRANSFER => false,
CURLOPT_HTTPHEADER => array(
 "accept: application/json",
 "cache-control: no-cache",
 "content-type: application/json"
),
));

echo $response = curl_exec($curl);
$err = curl_error($curl);

curl_close($curl);

if ($err) {
 echo "cURL Error #:" . $err;
} else {
 echo $response;
}  
?>
