恢复Ruby中的文件下载，范围标题问题 [英] Resuming file downloads in Ruby, range header issue

问题描述

在Ruby 1.8.7中设置范围标题时，会添加一个额外的X-REMOVED：Range标题，这（看似）会阻止下载恢复工作。

When setting a range header in Ruby 1.8.7, an additional "X-REMOVED: Range" header is being added, which (seemingly) prevents download resumes from working.

size = File.size(local_file)
Net::HTTP.start(domain) do |http|
  headers = { 
    'Range' => "bytes=#{size}-"
  }
  resp = http.get(remote_file, headers)
  open(local_file, "wb") do |file|
    file.write(resp.body)
  end
end

已发送标题：

GET /test.zip HTTP/1.1..Host: 192.168.50.1..Accept: */*..X-REMOVED: Range..Range: bytes=481-....

我'我也尝试使用具有相同结果的set_range。

I've also tried using set_range with the same result.

推荐答案

这很令人尴尬。恢复不起作用与范围标题无关。只是我用wb而不是ab打开文件。

Well this is embarrassing. The resumes not working had nothing to do with the range header. It's just that I was opening the file with "wb" instead of "ab".
