问题描述
我收到一个错误，无法解析 host：www.localhost 。我不知道为什么会这样。
I get an error could not resolve host:www.localhost. I don't know why it is coming.
$url ="http://www.localhost:81/dbWIP/selectApi.php?name=".$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);
推荐答案
删除 www。
像这样
$url ="http://localhost:81/dbWIP/selectApi.php?name=".$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);
并验证您的端口号 81
netstat -a -b
告诉您绑定到端口81的程序是什么
that's tell you what program is bound to port 81
