标签： php facebook curl get

【解决方案1】：

如果您删除 POST 的选项并执行常规的 GET 请求，它会起作用：

<?php

function imagedownload($url, $saveto)
{
    $ch = curl_init($url);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
    curl_setopt($ch, CURLOPT_HEADER, false);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
    $result = parse_url($url);
    curl_setopt($ch, CURLOPT_REFERER, $result['scheme'] . '://' . $result['host']);
    curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 10.0; WOW64; rv:45.0) Gecko/20100101 Firefox/45.0');
    $raw = curl_exec($ch);
    curl_close($ch);
    if (file_exists($saveto)) {
        unlink($saveto);
    }
    $fp = fopen($saveto, 'x');
    fwrite($fp, $raw);
    fclose($fp);
}

$url = "http://scontent-frt3-1.xx.fbcdn.net/v/t1.0-0/cp0/e15/q65/p320x320/13700038_850487491753797_6227258625184891703_n.jpg?oh=793ecde8db1a8e65789534907d08b25e&oe=57F1DDFF";
$konum = "test.jpg";

$yolla = imagedownload($url, $konum);

【讨论】：

但问题仍然存在
它对我有用，所以请尝试启用CURLOPT_VERBOSE，然后看看它说了什么。

【解决方案2】：

我已经在我的本地主机中尝试了这段代码，它运行良好。

<?php
ini_set('display_errors', 1);
function imagedownload($url,$saveto){
    $ch = curl_init ($url);
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_BINARYTRANSFER,1);
    $raw=curl_exec($ch);
    curl_close ($ch);
    if(file_exists($saveto)){
    unlink($saveto);
    }
    $fp = fopen($saveto,'x');
    fwrite($fp, $raw);
    fclose($fp);
}
$url="http://scontent-frt3-1.xx.fbcdn.net/v/t1.0-0/cp0/e15/q65/p320x320/13700038_850487491753797_6227258625184891703_n.jpg?oh=793ecde8db1a8e65789534907d08b25e&oe=57F1DDFF";
$konum="/var/www/html/jsPDF-master/examples/test.jpg";
$yolla=imagedownload($url,$konum);
?>

结果

还有一点注意：请确保保存图片的目录必须有写权限。

示例：chmod -R 777 /var/www/html/jsPDF-master/examples

或者确保在 php.ini 中启用 allow_url_fopen
