我正在尝试使用curl从URL获取HTML源。
下面的代码在localhost上可以正常使用,但是当移至服务器时它不会返回任何内容:
function get_html_from_url($url) {
$options = array(
CURLOPT_RETURNTRANSFER => true,
CURLOPT_HEADER => false,
CURLOPT_FOLLOWLOCATION => false,
CURLOPT_ENCODING => "",
CURLOPT_USERAGENT => "User-agent: Mozilla/5.0 (iPhone; U; CPU like Mac OS X; en) AppleWebKit/420.1 (KHTML, like Gecko) Version/3.0 Mobile/3B48b Safari/419.3",
CURLOPT_AUTOREFERER => true,
CURLOPT_CONNECTTIMEOUT => 30,
CURLOPT_HTTPHEADER => array(
"Host: host.com",
"Upgrade-Insecure-Requests: 1",
"User-Agent: Mozilla/5.0 (Linux; Android 6.0; Nexus 5 Build/MRA58N) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/69.0.3497.100 Mobile Safari/537.36",
"Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8",
"Accept-Encoding: gzip, deflate",
"Accept-Language: en-US,en;q=0.9",
"Cookie: JSESSIONID=SESSSIONID",
"Connection: close"
),
CURLOPT_TIMEOUT => 30,
CURLOPT_MAXREDIRS => 10,
CURLOPT_SSL_VERIFYPEER => false,
);
$ch = curl_init( $url );
curl_setopt_array( $ch, $options );
$content = curl_exec( $ch );
$err = curl_errno( $ch );
$errmsg = curl_error( $ch );
$header = curl_getinfo( $ch );
curl_close( $ch );
$header['errno'] = $err;
$header['errmsg'] = $errmsg;
$header['content'] = $content;
return $header;
}
我在服务器上收到超时错误,甚至尝试增加超时但没有运气!
谢谢。

您可以使用file_get_contents()
进行测试,如下所示:
$url = file_get_contents('http://example.com');
echo $url;
但是使用Curl是可行的方法。我会检查您从服务器获得了哪些网络访问权限?

这是一个示例代码,可获取远程url数据并存储在文件中。希望对您有帮助。
function scrapper()
{
$url = "https://www.google.com/";
$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_RETURNTRANSFER => 1,
CURLOPT_URL => $url
));
$response = curl_exec($curl);
return $response;
}
$scrap_data = scrapper();
$myfile = fopen("scrap_data.txt", "w") or die("Unable to open file!");
fwrite($myfile, $scrap_data);
fclose($myfile);
echo "Scrapped data saved inside file";

如果我正确理解了您的要求,那么以下脚本应该可以帮助您。您可以使用htmlspecialchars()来获得所需的输出。
<?php
function get_content($url) {
$options = array(
CURLOPT_RETURNTRANSFER => 1,
CURLOPT_USERAGENT => "Mozilla/5.0",
);
$ch = curl_init( $url );
curl_setopt_array( $ch, $options );
$htmlContent = curl_exec( $ch );
curl_close( $ch );
return $htmlContent;
}
$link = "https://stackoverflow.com/questions/52477020/get-html-from-a-url-using-curl-in-php";
$response = get_content($link);
echo htmlspecialchars($response);
?>
我在脚本中使用的链接只是一个占位符。随时用您所追求的替代。
