使用XZIP在C ++中打开一个zip文件 [英] Opening a zip file in C++ with XZIP

问题描述

在我当前的项目中，我必须转到某个用户输入的目录，打开该目录并读取该目录中所有以W开头的zip文件.我试图使用XZIP库打开ZIP文件，但是我肯定做错了什么.我对使用UnzipItem还是Openzip打开zip文件并解析其内容感到困惑. (每个zip文件都包含一些.jpg文件，我必须将这些文件复制到另一个位置，但这是项目的第二部分)

另一个主要问题是我给Openzip打电话的方式.这不是调用函数的正确方法，我想就我的代码了解调用它的正确方法.

我真的很感谢您的帮助，谢谢:)

这是我的代码-

In my current project, I have to go to a certain user inputted directory, open that directory and read all the zip files in that directory which begin with W. I am trying to use the XZIP library for opening the ZIP files, but I am certainly doing something very wrong. I am confused whether to use UnzipItem or Openzip to open the zip file and parse through its contents. (The zip files each contain some .jpg files and I have to copy those files into another location, but that''s the second part of the project)

Another major issue is the way I am calling Openzip. this is not the correct way to call the function, I would like to know the correct way to call it with respect to my code.

I would really appreciate some help, Thanks :)

Here is my code-

#include "StdAfx.h"
#include "src\XZip.h"
#include "src\XUnzip.h"
int main()
{
  std::ifstream fin;
  std::string dir, filepath;
  int num;
  DIR *dp;
  struct dirent *dirp;
  struct stat filestat;
  std::string filename;
  std::string userInput;
  std::cout <<"Input dir to get files from: ";
  getline( std::cin, dir );  // gets everything the user
  dp = opendir( dir.c_str() );
  if (dp == NULL) {
        std::cout << "Error opening " << dir << std::endl;
    }
  char test[2];
  while ((dirp = readdir( dp )) != NULL)
    {  // printf(" inside the directory ");
        filepath = dir+"/" + dirp->d_name;
        filename =dirp.d_name;
        test[0]=filename[0];
        test[1]='\0';
        if ( test[0]=='W')
        {   HZIP* z;
            DWORD File_name = std::strtoul(filename.c_str(), NULL, 16);
            OpenZip(z,0,File_name);
        }

  }
    return 0;
}

推荐答案

看看这篇文章.我认为这与他使用的库相同，他非常简洁地说明了如何使用它. (我认为他们甚至为此包装)

Have a look at this article. I think it''s the same library he uses and he explains very neatly how to work with it. (I think theirs even a wrapper for it)
