php curl回来空的内容

嘿，我一直在寻找一个解决方案的问题一段时间了，但目前为止没有运气......基本上，我想要在PHP中使用curl下拉页面内容。而下面的代码php curl回来空的内容

static function getContent($url) { 
    // pull down the content that the url pointing to 
    $curl = curl_init($url); 
    curl_setopt($curl, CURLOPT_HEADER, false); 
    curl_setopt($curl, CURLOPT_VERBOSE, false); 
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, true); 
    curl_setopt($curl, CURLOPT_BINARYTRANSFER, true); 
    curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true); 
    curl_setopt($curl, CURLOPT_AUTOREFERER, true); 
    curl_setopt($curl, CURLOPT_USERAGENT, Constants::$USER_AGENT_CHROME); 
    $cookie = realpath(Constants::$ROOT_DIR . Constants::$COOKIE); 
    curl_setopt($curl, CURLOPT_COOKIEJAR, $cookie); 
    curl_setopt($curl, CURLOPT_COOKIEFILE, $cookie); 
    curl_setopt($curl, CURLOPT_FAILONERROR, true); 
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false); 
    curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false); 
    curl_setopt($curl, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_2_0); 
    // curl_setopt ($curl, CURLOPT_CAINFO, dirname(__FILE__).'/cacert.pem'); 
    $content = curl_exec($curl); 
    curl_close($curl); 
    return $content; 
    }

和调用该函数使用下列URL总是返回我空的内容，并没有问题，到目前为止，与其他不同的URL（来自不同域），我试过了。

$ url ='https://www.etsy.com/listing/150723421/iretrofone-20-steampunk-silver';

任何原因为什么？

[编辑]我在亚马逊Linux上运行这个脚本，机器上可能会丢失一些东西，使问题暴露出来。迄今为止的两个答案都不适用于我。

[编辑]以下是curl_getinfo输出

{"url":"https:\/\/www.etsy.com\/listing\/150723421\/iretrofone-20-steampunk-silver","content_type":"text\/html; charset=UTF-8","http_code":200,"header_size":737,"request_size":287,"filetime":-1,"ssl_verify_result":0,"redirect_count":0,"total_time":0.404801,"namelookup_time":0.028505,"connect_time":0.065447,"pretransfer_time":0.243564,"size_upload":0,"size_download":0,"speed_download":0,"speed_upload":0,"download_content_length":0,"upload_content_length":-1,"starttransfer_time":0.40422,"redirect_time":0,"redirect_url":"","primary_ip":"199.27.79.249","certinfo":[],"primary_port":443,"local_ip":"172.31.29.192","local_port":44605}

我测试你的代码，我得到了我的本地主机的PHP 5.5的内容也许有一些与您的安装只是尝试在另一台机器 –

试试这个代码，它与无饼干工作。

<?php 
function getContent($url) { 
$curl = curl_init($url); 
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true); 
curl_setopt($curl, CURLOPT_HEADER, false); 
$data = curl_exec($curl); 
curl_close($curl); 
return $data; 
} 

$url = 'https://www.etsy.com/listing/150723421/iretrofone-20-steampunk-silver'; 

echo $a = getContent($url); 
?>

试过代码，仍然没有工作。 – bcbishop

你在你的服务器上安装了curl吗？ –
