QNetworkManager默认是否接受压缩回复？ [英] Does QNetworkManager get accept compressed replies by default?

问题描述

我正在使用 QNetworkManager 从服务器获取文件，但是我不能弄清楚，如果文件在传输过程中使用标准gzip压缩进行压缩，如果不是如何让它们下载压缩文件。

I am using QNetworkManager to fetch files from a server, however what I cannot figure out is if the files are compressed during the transfer with the standard gzip compression and if not how to get them to download compressed.

我将如何进行检查？

推荐答案

我刚刚添加了快速测试：

I just ran a quick test by adding:

request.setRawHeader("Accept-Encoding", "gzip,deflate");

到QNetworkRequest，数据返回看起来压缩的内容（因为它减小了约20％且无法使用）。

to the QNetworkRequest and the data returns what look compressed (because its ~20% smaller and unusable).

就解压缩而言，QNetworkManager和QNetworkReply似乎并不智能。看起来我必须在返回的QByteArray上实现gzip和/或deflate。

It appears that the QNetworkManager and the QNetworkReply are not intelligent as far as decompression is concerned. It looks like I have to implement a gzip and/or deflate on the returned QByteArray.
