使用PHP中的curl从URL获取HTML [英] Get HTML from URL using curl in PHP

问题描述

我正在尝试使用curl从URL获取HTML源。

I am trying to get HTML source from URL using curl.

下面的代码在localhost中可以很好地工作，但是当移至服务器时它不会返回任何内容：

The below code works perfectly in localhost but it does not return anything when moved to server:

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，但是没有

I get timeout error on server and I even tried to increase the timeout but no luck!

谢谢。

推荐答案

如果我正确理解了您的要求，以下脚本将带您到达那里。您可以使用 htmlspecialchars（）来获得所需的功能

If I correctly understood your requirement, the following script should get you there. There is a function you can make use of htmlspecialchars() to get the desired output.

<?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。随时用您想要的那个替换它。

The link I've used within the script is just a placeholder. Feel free to replace that with the one you are after.
