使用 PHP 下载远程文件到服务器

2022-01-02 00:00:00 file download php

过去两天我一直在四处寻找并尝试了所有方法，但仍然无法正常工作.我觉得这应该是一件比较简单的事情.

I've been looking all over the place for the last two days and trying everything and still can't get anything to work. I feel like this should be a relatively simple thing to do.

我想要做的就是将远程文件从 URL 下载到我服务器上的目录.

All I want to do is download a remote file from a URL to a directory on my server.

例如，如果

$_url = http://www.freewarelovers.com/android/download/temp/1306495040_Number_Blink_1.1.1.apk

和 $_dir =/www/downloads/

然后当一切都说完了我想要1306495040_Number_Blink_1.1.1.apk在/www/downloads/

Then when all is said and done I want 1306495040_Number_Blink_1.1.1.apk in /www/downloads/

我试过 copy() 函数，我试过

I've tried the copy() function, I've tried

file_put_contents("$_dir.$_file_name", file_get_contents($_url));

并得到以下错误:

file_get_contents(): 无法打开流:HTTP 请求失败！

推荐答案

应该这样做:

set_time_limit(0);

$url = 'http://www.freewarelovers.com/android/download/temp/1306495040_Number_Blink_1.1.1.apk';
$file = fopen(dirname(__FILE__) . '/downloads/a.apk', 'w+');

$curl = curl_init();

// Update as of PHP 5.4 array() can be written []
curl_setopt_array($curl, [
    CURLOPT_URL            => $url,
//  CURLOPT_BINARYTRANSFER => 1, --- No effect from PHP 5.1.3
    CURLOPT_RETURNTRANSFER => 1,
    CURLOPT_FILE           => $file,
    CURLOPT_TIMEOUT        => 50,
    CURLOPT_USERAGENT      => 'Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)'
]);

$response = curl_exec($curl);

if($response === false) {
    // Update as of PHP 5.3 use of Namespaces Exception() becomes Exception()
    throw new Exception('Curl error: ' . curl_error($curl));
}

$response; // Do something with the response.
