我是
PHP的新手.我发送PHP curl POST请求后尝试从响应中获取Header.客户端将请求发送到服务器,服务器使用Header发回响应.这是我发送POST请求的方式.
$client = curl_init($url); curl_setopt($client,CURLOPT_CUSTOMREQUEST,"POST"); curl_setopt($client,CURLOPT_POSTFIELDS,$data_string); curl_setopt($client,CURLOPT_HEADER,1); $response = curl_exec($client); var_dump($response);
这是我从浏览器获得的服务器的头响应

它将所有标头转换为数组
// create curl resource
$ch = curl_init();
// set url
curl_setopt($ch,CURLOPT_URL,"example.com");
//return the transfer as a string
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
//enable headers
curl_setopt($ch,1);
//get only headers
curl_setopt($ch,CURLOPT_NOBODY,1);
// $output contains the output string
$output = curl_exec($ch);
// close curl resource to free up system resources
curl_close($ch);
$headers = [];
$data = explode("\n",$output);
$headers['status'] = $data[0];
array_shift($data);
foreach($data as $part){
$middle=explode(":",$part);
$headers[trim($middle[0])] = trim($middle[1]);
}
// Print all headers as array
echo "<pre>";
print_r($headers);
echo "</pre>";
