卷曲錯誤：無法解析主機：www.localhost

Question

我收到一個錯誤，無法解析host:www.localhost 。 我不知道為什么會這樣。

$url ="http://www.localhost:81/dbWIP/selectApi.php?name=".$name;
$client = curl_init();
echo $client;
curl_setopt($client, CURLOPT_URL,$url);
curl_setopt($client,CURLOPT_RETURNTRANSFER,true);
curl_setopt($client, CURLOPT_HEADER, false);
$response = curl_exec($client);
curl_close($client);
echo $response
$result = json_decode($response);

Answer 1

刪除www. 在網址中

像這樣

$url ="http://localhost:81/dbWIP/selectApi.php?name=".$name;
$client = curl_init();
echo $client;
curl_setopt($client, CURLOPT_URL,$url);
curl_setopt($client,CURLOPT_RETURNTRANSFER,true);
curl_setopt($client, CURLOPT_HEADER, false);
$response = curl_exec($client);
curl_close($client);
echo $response
$result = json_decode($response);

並驗證您的端口號81

netstat -a -b

告訴您什么程序綁定到端口81
