libcurl中是否有可用的压缩 [英] Is there any compression available in libcurl

问题描述

我需要使用libcurl和C ++将一个庞大的文件从本地机器传输到远程机器。有没有任何压缩选项可用内置libcurl。由于要传输的数据量很大（大小为100 MB到1 GB），因此如果我们在libcurl本身中有任何这样的选项会更好。我知道我们可以压缩数据并通过libcurl发送它。但只是想知道是否有任何更好的方式这样做。

I need to transfer a huge file from local machine to remote machine using libcurl with C++. Is there any compression option available in-built with libcurl. As the data to be transferred is large (100 MB to 1 GB in size), it would be better if we have any such options available in libcurl itself. I know we can compress the data and send it via libcurl. But just want to know is there any better way of doing so.

注意：在我的情况下，许多客户端计算机会定期将这样大量的数据传输到远程服务器。

Note: In my case, many client machines transfer such huge data to remote server at regular interval of time.

推荐答案

根据 curl_setopt（） 和选项 CURLOPT_ENCODING ，您可以指定：

According to curl_setopt() and options CURLOPT_ENCODING, you may specify:

Accept-Encoding：标题的内容。这使得解码
的响应。支持的编码为identity，deflate和
gzip。如果设置了空字符串，则会发送包含所有
支持的编码类型的标题。

The contents of the "Accept-Encoding: " header. This enables decoding of the response. Supported encodings are "identity", "deflate", and "gzip". If an empty string, "", is set, a header containing all supported encoding types is sent.

此处是一些示例（只需在您的浏览器中点击搜索，然后键入 compression ），但我不知道热完全是否工作，以及它是否期望已经gzip压缩的数据。

Here are some examples (just hit search in your browser and type in compression), but I don't know hot exactly does it work and whether it expect already gzipped data.

a href =http://php.net/manual/en/function.gzcompress.php =nofollow> gzcompress（） 并发送压缩块自己（我将这样做任务...你将更好地控制实际发生了什么，你将能够改变使用的算法）。

You still may use gzcompress() and send compressed chunks on your own (and I would do the task this way... you'll have better control on what's actually going on and you'll be able to change used algorithms).
