如何使用 CURL 代替 file_get_contents?

发布于 2024-12-21 18:37:41 字数 517 浏览 0 评论 0原文

我使用 file_get_contents 函数来获取并显示我的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 函数,因此我尝试使用 cURL 和以下代码:

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。怎么了?

I use file_get_contents function to get and show external links on my specific page.

In my local file everything is okay, but my server doesn't support the file_get_contents function, so I tried to use cURL with the below code:

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');

But it returns a blank page. What is wrong?

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;
}

try this:

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;
}

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);

This should work

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);

//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");

//You can try this . It should work fine.

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");

我通过直接链接访问 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.

使用下面的代码它再次工作:

//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;

我今天测试了它,03/19/2018

I encountered such a problem accessing Google Drive content via the direct link.

After calling file_get_contents returned 302 Moved temporarily

//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.

With the code below it worked again:

//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;

I tested it today, 03/19/2018
