How to remove HTTP headers from CURL response?
提问by Upvote
I have a php script that returns just plain text withoutany html. Now I want to make a cURL request to that script and I get the following response:
我有一个 php 脚本，它只返回纯文本，没有任何 html。现在我想向该脚本发出 cURL 请求，并得到以下响应：
HTTP/1.1 200 OK
Date: Mon, 28 Feb 2011 14:21:51 GMT
Server: Apache/2.2.14 (Ubuntu)
X-Powered-By: PHP/5.2.12-nmm2
Vary: Accept-Encoding
Content-Length: 6
Content-Type: text/html
6.8320
The actuall response is just 6.8320as text without any html. I want to retrieve it from the response above by just removing the header information.
实际响应只是6.8320作为没有任何 html 的文本。我想通过删除标头信息从上面的响应中检索它。
I already minified the script a bit:
我已经将脚本缩小了一点：
$url = $_GET['url'];
if ( !$url ) {
// Passed url not specified.
$contents = 'ERROR: url not specified';
$status = array( 'http_code' => 'ERROR' );
} else if ( !preg_match( $valid_url_regex, $url ) ) {
// Passed url doesn't match $valid_url_regex.
$contents = 'ERROR: invalid url';
$status = array( 'http_code' => 'ERROR' );
} else {
$ch = curl_init( $url );
if ( strtolower($_SERVER['REQUEST_METHOD']) == 'post' ) {
curl_setopt( $ch, CURLOPT_POST, true );
curl_setopt( $ch, CURLOPT_POSTFIELDS, $_POST );
}
curl_setopt( $ch, CURLOPT_FOLLOWLOCATION, true );
curl_setopt( $ch, CURLOPT_HEADER, true );
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );
curl_setopt( $ch, CURLOPT_USERAGENT, $_GET['user_agent'] ? $_GET['user_agent'] : $_SERVER['HTTP_USER_AGENT'] );
list( $header, $contents ) = preg_split( '/([\r\n][\r\n])\1/', curl_exec( $ch ), 2 );
$status = curl_getinfo( $ch );
curl_close( $ch );
}
// Split header text into an array.
$header_text = preg_split( '/[\r\n]+/', $header );
if ( true ) {
if ( !$enable_native ) {
$contents = 'ERROR: invalid mode';
$status = array( 'http_code' => 'ERROR' );
}
// Propagate headers to response.
foreach ( $header_text as $header ) {
if ( preg_match( '/^(?:Content-Type|Content-Language|Set-Cookie):/i', $header ) ) {
header( $header );
}
}
print $contents;
}
Any idea what I need to change to remove the header information from the response?
知道我需要更改什么才能从响应中删除标头信息吗？

Just set CURLOPT_HEADERto false.
只需设置CURLOPT_HEADER为false。

Do this after your curl call:
在 curl 调用后执行此操作：
$header_size = curl_getinfo($ch, CURLINFO_HEADER_SIZE);
$header = substr($response, 0, $header_size);
$body = substr($response, $header_size);

Update the value of CURLOPT_HEADER to 0 for false
将 CURLOPT_HEADER 的值更新为 0 为假
curl_setopt($ch, CURLOPT_HEADER, 0);

Just for a later use if anyone else needs. I was into same situation, but just need to remove header text, not content. The response i was getting in the header was (including white space):
如果其他人需要，仅供以后使用。我遇到了同样的情况，但只需要删除标题文本，而不是内容。我在标题中得到的响应是（包括空格）：
HTTP/1.1 200 OK
Cache-Control: private, no-cache, no-store, must-revalidate
Content-Language: en
Content-Type: text/html
Date: Tue, 25 Feb 2014 20:59:29 GMT
Expires: Sat, 01 Jan 2000 00:00:00 GMT
Pragma: no-cache
Server: nginx
Vary: Cookie, Accept-Language, Accept-Encoding
transfer-encoding: chunked
Connection: keep-alive
I wanted to remove starting from HTTP till keep-alive with white space:
我想从 HTTP 开始删除，直到用空格保持活动状态：
$contents = preg_replace('/HTTP(.*)alive/s',"",$contents);
that did for me.
这对我有用。

If for some reason you have to curl_setopt($ch, CURLOPT_HEADER, 1);to get cookies for example, the following worked for me. Not sure if it's 100% reliable but worth a try
curl_setopt($ch, CURLOPT_HEADER, 1);例如，如果由于某种原因您必须获取 cookie，以下内容对我有用。不确定它是否 100% 可靠，但值得一试
$foo = preg_replace('/HTTP(.*)html/s',"",$curlresult);

$content = null;
$ch = curl_init();
$rs = curl_exec($ch);
if (CURLE_OK == curl_errno($ch)) {
$content = substr($rs, curl_getinfo($ch, CURLINFO_HEADER_SIZE));
}
curl_close($ch);
echo $content;

If you are using nuSoap, you can access data without headers with $nsoap->responseDataor $nsoap->response, if you want the full headers.
如果您正在使用nuSoap，则可以使用$nsoap->responseData或访问没有标题的数据$nsoap->response，如果您想要完整的标题。
Just in case someone needs that.
以防万一有人需要。

If someone already saved the curl response to a file (like me) and therefore don't know how big the header was to use substr, try:
如果有人已经将 curl 响应保存到文件（像我一样），因此不知道使用 substr 的标头有多大，请尝试：
$file = '/path/to/file/with/headers';
file_put_contents($file, preg_replace('~.*\r\n\r\n~s', '', file_get_contents($file)));

Just do not set the curl_headerin the curl request or set it to z or false
like thiscurl_setopt($ch, CURLOPT_HEADER, 0);curl_setopt($ch, CURLOPT_HEADER, false);
只是不要curl_header在 curl 请求中设置或将其设置为z or false
这样curl_setopt($ch, CURLOPT_HEADER, 0);curl_setopt($ch, CURLOPT_HEADER, false);

Just don't set CURLOPT_HEADER!
只是不要设置CURLOPT_HEADER！
