使用PHP将远程文件下载到服务器

Question

在过去的两天里,我一直在寻找所有的地方并尝试一切,仍然无法得到任何工作.我觉得这应该是一件相对简单的事情.

我想要做的就是从URL下载远程文件到我服务器上的目录.

所以,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,当一切都说过和做过我想1306495040_Number_Blink_1.1.1.apk在/www/downloads/

我试过这个copy()功能,我试过了

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

并得到以下错误:

file_get_contents(): failed to open stream: HTTP request failed!

Answer 1

这应该这样做:

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.

$url  = 'http://www.example.com/a-large-file.zip';
$path = '/path/to/a-large-file.zip';

$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$data = curl_exec($ch);

curl_close($ch);

file_put_contents($path, $data);

它使用卷曲

$ url是文件网址

$ path是保存文件的位置和名称

我希望它有效

使用curl从远程服务器下载文件,如下所示.

$url = "http://path/toserver/filename";
$destination = "uploads/filename";    
$fp = fopen ($destination, 'w+');
  $ch = curl_init();
  curl_setopt( $ch, CURLOPT_URL, $url );
  curl_setopt( $ch, CURLOPT_BINARYTRANSFER, true );
  curl_setopt( $ch, CURLOPT_RETURNTRANSFER, false );
  curl_setopt( $ch, CURLOPT_SSL_VERIFYPEER, false );

  curl_setopt( $ch, CURLOPT_CONNECTTIMEOUT, 10 );
  curl_setopt( $ch, CURLOPT_FILE, $fp );
  curl_exec( $ch );
  curl_close( $ch );
  fclose( $fp );

Answer 4

自 PHP 5.1.0 起，file_put_contents() 支持通过将流句柄作为 $data 参数传递来逐段写入：
无需使用 Curl

file_put_contents("Tmpfile.zip", fopen("http://someurl/file.zip", 'r'));

Answer 5

file_put_contents需要文件名，而不是目录名。
