我試圖從網站獲取字串，但我得到的是外部網站的 404 頁而不是索引頁字串。
我已經嘗試過cURL和file_get_contents。兩者都從外部網站回傳 404 而不是回傳索引頁面的字串。
$homepage = file_get_contents("https://www.creditkarma.ca");
echo $homepage;
卷曲：
$agent= 'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.0.3705; .NET CLR 1.1.4322)';
function file_get_contents_curl($url) {
$ch = curl_init();
curl_setopt($ch, CURLOPT_AUTOREFERER, TRUE);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_USERAGENT, $agent);
curl_setopt($ch, CURLOPT_VERBOSE, true);
$data = curl_exec($ch);
curl_close($ch);
return $data;
}
$homepage = file_get_contents_curl("https://www.creditkarma.ca");
echo $homepage;
該代碼應回傳索引頁面的字串，但它回傳來自外部網站的 404 頁面。我該如何解決這個問題。我需要一串索引頁。
注意：它回傳的外部網站的 404 不是來自我的 .htaccess
uj5u.com熱心網友回復：
使用 CURL 陳述句，如果您想檢索頁面的 HTML，您應該使用headers. 作為安全預防措施，如果瀏覽器資訊不明顯，許多網站會拒絕流量（或導致 404）。所以當我這樣做時.. 我嘗試“模仿”我的陳述，就好像它是一個瀏覽器一樣。像這樣的東西應該符合要求 - 正如您在上面更新的代碼中所述，您不是在表示“代理”：
$url="https://www.creditkarma.ca";
$agent= 'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.0.3705; .NET CLR 1.1.4322)';
$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_VERBOSE, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_USERAGENT, $agent);
curl_setopt($ch, CURLOPT_URL,$url);
$result=curl_exec($ch);
var_dump($result);
