使用PHP和CURL下载受htaccess保护的文件

Question

我尝试使用php和curl在htaccess受保护的目录中下载文件.这是我的代码:

$username = "MyUsername";
$password = "MyPassword";
$url = "http://www.example.com/private/file.pdf";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_USERPWD, "$username:$password");
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
$output = curl_exec($ch);
$info = curl_getinfo($ch);
curl_close($ch);

但是这段代码什么也没做......我怎样才能开始下载file.pdf？

谢谢!

另外,如果我回显$ output,我得到这个:

Array ( [url] => http://www.example.com/private/file.pdf [content_type] => application/pdf [http_code] => 200 [header_size] => 264 [request_size] => 116 [filetime] => -1 [ssl_verify_result] => 0 [redirect_count] => 0 [total_time] => 0.007898 [namelookup_time] => 0.006777 [connect_time] => 0.006858 [pretransfer_time] => 0.006922 [size_upload] => 0 [size_download] => 27369 [speed_download] => 3465307 [speed_upload] => 0 [download_content_length] => 27369 [upload_content_length] => 0 [starttransfer_time] => 0.007839 [redirect_time] => 0 )

Answer 1

这是工作代码,你犯了一个错误: curl_setopt($curl, CURLOPT_BINARYTRANSFER, 1);

$username = "MyUsername";
$password = "MyPassword";
$url = "http://www.example.com/private/file.pdf";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_BINARYTRANSFER, 1);
curl_setopt($ch, CURLOPT_USERPWD, "$username:$password");
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
$output = curl_exec($ch);
$info = curl_getinfo($ch);
curl_close($ch);
header("Content-Type: application/octet-stream");
header("Content-Disposition: attachment; filename=file.pdf");
echo ($output);

Answer 2

有一个CURLOPT_BINARYTRANSFER选项似乎缺失。顺便说一句，您粘贴的输出$info不是$output。它显示下载已发生，download_content_length为 27369。
