我发现了为什么会这样,检查我的答案

这是发生这种情况的唯一域,我在一堆 URL 上运行 curl_multi,这个返回 404 http_code http://www.breaknews.com

但是当我在浏览器中访问它时,它是 200OK(需要一段时间才能加载)并且看起来甚至不像重定向。

有谁知道怎么回事?这是个常见的问题吗

这是一个 var_dump:

 ["info"]=> array(22) { ["url"]=> string(27) "http://www.breakingnews.com" ["content_type"]=> string(24) "text/html; charset=utf-8" ["http_code"]=> int(404) ["header_size"]=> int(337) ["request_size"]=> int(128) ["filetime"]=> int(-1) ["ssl_verify_result"]=> int(0) ["redirect_count"]=> int(0) ["total_time"]=> float(1.152229) ["namelookup_time"]=> float(0.001261) ["connect_time"]=> float(0.020121) ["pretransfer_time"]=> float(0.020179) ["size_upload"]=> float(0) ["size_download"]=> float(9755) ["speed_download"]=> float(8466) ["speed_upload"]=> float(0) ["download_content_length"]=> float(-1) ["upload_content_length"]=> float(0) ["starttransfer_time"]=> float(1.133522) ["redirect_time"]=> float(0) ["certinfo"]=> array(0) { } ["redirect_url"]=> string(0) "" } ["error"]=> string(0) ""

更新:这实际上看起来像 curl_setopt($ch, CURLOPT_NOBODY, true); 的 php 错误 https://bugs.php.net/bug.php?id=39611

编辑:这不是错误。

我在这里的评论中找到了答案http://w-shadow.com/blog/2007/08/02/how-to-check-if-page-exists-with-curl/comment-page-1/#comment -12186 通过将 CURLOPT_NOBODY 设置为 true,CURL 将使用 HEAD 来处理某些服务器不喜欢的请求(例如,福布斯),并将返回“Emply reply from server”。要修复,您还需要设置 CURLOPT_HTTPGET 以重置回 GET 请求。

/* don’t download the page, just the header (much faster in this case) */
curl_setopt($ch, CURLOPT_NOBODY, true);
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_HTTPGET, true); //this is needed to fix the issue

我不确定你的代码是什么样的,但这很好用

$url = "http://www.breakingnews.com";
$ch = curl_init ( $url );
curl_setopt ( $ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; pl; rv:1.9) Gecko/2008052906 Firefox/3.0" );
curl_setopt ( $ch, CURLOPT_AUTOREFERER, true );
curl_setopt ( $ch, CURLOPT_FOLLOWLOCATION, true );
curl_setopt ( $ch, CURLOPT_RETURNTRANSFER, 1 );

curl_exec ( $ch );
var_dump ( curl_getinfo ( $ch ) );
if (curl_errno ( $ch )) {
    print curl_error ( $ch );
} else {
    curl_close ( $ch );
}

输出

  'http_code' => int 200
