php将远程动态文件下载到本地服务器

Question

当我向远程http://aa.com/generatefeed.php

发出服务器端呼叫时

它应该实时下载feed_randomnumber.csv（随机文件名）并将其保存为本地服务器。

但它不起作用。

出了什么问题。

getfeed.php

getremotetofile("http://aa.com/generatefeed.php");


public static function getremotetofile($fileurl)
{
    $newfilename= basename($fileurl);

    $destination=fopen($newfilename,"w");

    $source=fopen($fileurl,"r");
    $maxsize=3000;
    $length=0;
    while (($a=fread($source,1024))&&($length<$maxsize))
    {
        $length=$length+1024;
        fwrite($destination,$a);
    }
    fclose($source);
    fclose($destination);       

}

generatefeed.php

$fullcontent="bla,bla,bla";

header("Content-type:text/octect-stream");
header("Content-Disposition:attachment;filename=feed_randomnumber.csv");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Content-Length: " . strlen($strHeader));        

print $fullcontent;

exit;

Answer 1

尝试使用CURL而不是fopen，它可能会在您的服务器上禁用。

$file = "http://somelocation.com/somefile.php";
$ch = curl_init($file);
$fp = @fopen("temp.php", "w");
curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_exec($ch);
curl_close($ch);
fclose($fp);
$file = "temp.php";
$fp = fopen($file, "r");

定义对代码不起作用的内容。你在php配置中启用了allow_url_fopen吗？看看http://php.net/manual/en/features.remote-files.php

Answer 3

试试这个：

   getremotetofile("http://aa.com/generatefeed.php");


    public static function getremotetofile($fileurl)
    {
      $newfilename= basename($fileurl);
        $content = file_get_contents($fileurl);
        file_put_contents($newfilename, $content);

    }

Answer 4

file_put_contents('localFile.csv', file_get_contents('http://www.somewhere.com/function.php?action=createCSVfile'));

我用它来下载动态创建的远程csv并将其保存在本地服务器上。
