Question

我试图下载存在于不同服务器上的文件并将其移至我的新服务器。

我已经尝试了

$file = file_get_contents("https://exampleurl.com/file/download.txt");
file_put_contents("C:/directory/to/report/data.csv", $file);

以及

$remote_file_url = "https://exampleurl.com/file/download.txt";
$local_file = C:/directory/to/report/data.csv;
$copy = copy( $remote_file_url, $local_file );

但文件永远不会完成，它会切断文件的末尾。当我直接从网址下载文件时，它每次都完成。

我正在寻找确保文件完全下载的方法

通常使用卷曲请求file_get_contents超时会导致此类错误，并且只会加载部分内容。试试这个：

$ch=curl_init("https://exampleurl.com/file/download.txt"); //create a c url session
$timeout=300; //set time limit here depends upon the operations being done on the remote server currently its 5mins
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout); //set timeout for request
$content = curl_exec($ch);//execute request
if($content)
{
    $localfile = fopen("path to local file", "w"); //create or open a existing file
    if(fwrite($localfile , $content)) //write data received
        echo "success";
    else
        echo "unable to write file";
    fclose($localfile ); //close the file

}
else //error occured while executing the request on the remote server
    echo "Request Failed";

copy，file_get_contents，file_put_contents在新文件中没有获取完整内容
