是否有任何方法来获得头部和主体的cURL请求使用PHP?我发现这个选项:
curl_setopt($ch, CURLOPT_HEADER, true);
会返回body和header，但之后我需要解析它来得到body。有没有办法以更可用(和更安全)的方式同时获得两者?
注意，对于“单个请求”，我的意思是避免在GET/POST之前发出HEAD请求。

只需设置选项:
CURLOPT_HEADER, 0岁 CURLOPT_RETURNTRANSFER, 1
并使用curl_getinfo与CURLINFO_HTTP_CODE(或没有opt参数，你将有一个与所有你想要的信息的关联数组)

更好的方法是使用详细的CURL响应，可以通过管道连接到临时流。然后可以在响应中搜索报头名称。这可能需要一些调整，但对我来说很管用:
class genericCURL {
/**
* NB this is designed for getting data, or for posting JSON data
*/
public function request($url, $method = 'GET', $data = array()) {
$ch = curl_init();
if($method == 'POST') {
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $string = json_encode($data));
}
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_VERBOSE, true);
//open a temporary stream to output the curl log, which would normally got to STDERR
$err = fopen("php://temp", "w+");
curl_setopt($ch, CURLOPT_STDERR, $err);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$server_output = curl_exec ($ch);
//rewind the temp stream and put it into a string
rewind($err);
$this->curl_log = stream_get_contents($err);
curl_close($ch);
fclose($err);
return $server_output;
}
/**
* use the curl log to get a header value
*/
public function getReturnHeaderValue($header) {
$log = explode("\n", str_replace("\r\n", "\n", $this->curl_log));
foreach($log as $line) {
//is the requested header there
if(stripos($line, '< ' . $header . ':') !== false) {
$value = trim(substr($line, strlen($header) + 3));
return $value;
}
}
//still here implies not found so return false
return false;
}
}
如果你正在使用GET，试试这个:
$curl = curl_init($url);
curl_setopt_array($curl, array(
CURLOPT_URL => $url,
CURLOPT_RETURNTRANSFER => true,
CURLOPT_ENCODING => "",
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 30,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "GET",
CURLOPT_HTTPHEADER => array(
"Cache-Control: no-cache"
),
));
$response = curl_exec($curl);
curl_close($curl);
只需设置选项:
CURLOPT_HEADER, 0岁 CURLOPT_RETURNTRANSFER, 1
并使用curl_getinfo与CURLINFO_HTTP_CODE(或没有opt参数，你将有一个与所有你想要的信息的关联数组)

我的方法是
$response = curl_exec($ch);
$x = explode("\r\n\r\n", $v, 3);
$header=http_parse_headers($x[0]);
if ($header=['Response Code']==100){ //use the other "header"
$header=http_parse_headers($x[1]);
$body=$x[2];
}else{
$body=$x[1];
}
如果需要，应用for循环并移除爆炸限制。
返回带有引用参数的响应头:
<?php
$data=array('device_token'=>'5641c5b10751c49c07ceb4',
'content'=>'测试测试test'
);
$rtn=curl_to_host('POST', 'http://test.com/send_by_device_token', array(), $data, $resp_headers);
echo $rtn;
var_export($resp_headers);
function curl_to_host($method, $url, $headers, $data, &$resp_headers)
{$ch=curl_init($url);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $GLOBALS['POST_TO_HOST.LINE_TIMEOUT']?$GLOBALS['POST_TO_HOST.LINE_TIMEOUT']:5);
curl_setopt($ch, CURLOPT_TIMEOUT, $GLOBALS['POST_TO_HOST.TOTAL_TIMEOUT']?$GLOBALS['POST_TO_HOST.TOTAL_TIMEOUT']:20);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, false);
curl_setopt($ch, CURLOPT_HEADER, 1);
if ($method=='POST')
{curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));
}
foreach ($headers as $k=>$v)
{$headers[$k]=str_replace(' ', '-', ucwords(strtolower(str_replace('_', ' ', $k)))).': '.$v;
}
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
$rtn=curl_exec($ch);
curl_close($ch);
$rtn=explode("\r\n\r\nHTTP/", $rtn, 2); //to deal with "HTTP/1.1 100 Continue\r\n\r\nHTTP/1.1 200 OK...\r\n\r\n..." header
$rtn=(count($rtn)>1 ? 'HTTP/' : '').array_pop($rtn);
list($str_resp_headers, $rtn)=explode("\r\n\r\n", $rtn, 2);
$str_resp_headers=explode("\r\n", $str_resp_headers);
array_shift($str_resp_headers); //get rid of "HTTP/1.1 200 OK"
$resp_headers=array();
foreach ($str_resp_headers as $k=>$v)
{$v=explode(': ', $v, 2);
$resp_headers[$v[0]]=$v[1];
}
return $rtn;
}
?>
