如何解压缩已加载到 C 内存中的 zip 文件? [英] How to unzip a zip file already loaded in memory in C?

问题描述

我正在编写一个服务器，它从客户端接收一个 zip 文件，然后解压缩该文件.收到 zip 文件后，我将其存储到内存中.

I am writing a server, which receive a zip file from client, and unzip the file. When I receiving the zip file, I store it into memory.

我找到并尝试了一些库来上传 zip 文件，例如 zlib 和 minizip，但所有这些都解压缩了磁盘上存在的文件，而不是内存中.

I find and try some library to upzip a zip file, such zlib and minizip, but all of them unzip a file exists on disk, not from memory.

不想临时存盘再解压，效率不高.

I don't want to save the file into disk temperorily and extract it, it's not efficient.

推荐答案

看一看 libarchive支持zip格式.

Take a look at libarchive It supports the zip format.

在内存中提取存档的示例:

Example of extracting archive in memory:

struct archive *a = archive_read_new();
archive_read_support_compression_gzip(a);
archive_read_support_format_tar(a);
r = archive_read_open_memory(a, buff, sizeof(buff));
