使用PHP curl或类似的可恢复和部分下载？ [英] Resumable and partial download with PHP curl or similar?

问题描述

是否可以恢复下载部分下载的文件与curl或类似的？我的意思是，我们有一个大的dbdump.sql文件在 http 或 ftp 服务器是1 GB尺寸;我可以以某种方式告诉这个服务器请从字节 x 发送到字节 y ？

$ b $为了简单起见，我在寻找这个问题，不包括加入下载的块;

解决方案

您可以执行以下操作：

  curl_setopt（$ obj，CURLOPT_HTTPHEADER，array（Range：bytes = 1024000-2048000））; 
  

这当然只适用于HTTP。

Is is possible to resume downloading a partially downloaded file with curl or similar? I mean, let's say we have this big dbdump.sql file on a http or ftp server which is 1 GB in size; could I somehow tell this server please send from the file from byte x to byte y?

For simplicity's sake, what I'm looking for, with this question, does not include joining the downloaded chunks; rather just downloading the chunks and saving each as a septate file.

解决方案

You can do something like:

curl_setopt ($obj, CURLOPT_HTTPHEADER, array ("Range: bytes=1024000-2048000"));

This will work for HTTP only of course.
