php curl有时候我们需要设置header和获取header、网页返回码。
如下方法可以拿到
public function getCurlHttpHeader($url, $headers = null) {
if (empty($headers)) {
$headers = [];
}
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); //是否抓取跳转后的页面
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); // 跳过证书检查
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, true); // 从证书中检查SSL加密算法是否存在
curl_setopt($ch, CURLOPT_TIMEOUT, 10); // 设置超时限制防止死循环
curl_setopt($ch, CURLOPT_HEADER, 1); //取得返回头信息
$res = curl_exec($ch);
$headerSize = curl_getinfo($ch, CURLINFO_HEADER_SIZE);
$header = substr($res, 0, $headerSize);
$body = substr($res, $headerSize);
curl_close($ch);
return ['body' => $body, 'head' => $header];
}或者使用curl_getinfo($ch, CURLINFO_HTTP_CODE) 来判断返回码
