Question

我使用file_get_contents函数来获取并显示我特定页面上的外部链接。

在我的本地文件中一切正常，但我的服务器不支持file_get_contents功能，所以我尝试使用cURL和下面的代码：

function file_get_contents_curl($url) {
    $ch = curl_init();

    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_URL, $url);

    $data = curl_exec($ch);
    curl_close($ch);

    return $data;
}

 echo file_get_contents_curl('http://google.com');

但它返回一个空白页面。有什么问题？

Answer 1

试试这个：

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);       

    $data = curl_exec($ch);
    curl_close($ch);

    return $data;
}

Answer 2

这应该有效

function curl_load($url){
    curl_setopt($ch=curl_init(), CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    $response = curl_exec($ch);
    curl_close($ch);
    return $response;
}

$url = "http://www.google.com";
echo curl_load($url);

Answer 3

//你可以试试这个。它应该工作正常。

function curl_tt($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($ch, CURLOPT_SSL_VERIFYHOST, 3);     
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
$data = curl_exec($ch);
curl_close($ch);

return $data;
}
echo curl_tt("https://google.com");

Answer 4

我在通过直接链接访问Google云端硬盘内容时遇到了这样的问题。

调用file_get_contents后返回302暂时移动

//Any google url. This example is fake for Google Drive direct link.
$url = "https://drive.google.com/uc?id=0BxQKKJYjuNElbFBNUlBndmVHHAj";
$html = file_get_contents($url);
echo $html; //print none because error 302.

使用下面的代码再次起作用：

//Any google url. This example is fake for Google Drive direct link.
$url = "https://drive.google.com/uc?id=0BxQKKJYjuNElbFBNUlBndmVHHAj";

$ch = curl_init();
curl_setopt($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($ch, CURLOPT_SSL_VERIFYHOST, 3);     
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
$html = curl_exec($ch);
curl_close($ch);

echo $html;
