c++解压压缩包文件

news 2025/7/4 9:36:24

功能实现需要依赖相关头文件和库文件，我这里的是64位的。需要的可以在这下载：https://download.csdn.net/download/bangtanhui/88403596

参考代码如下：

#include <zip.h>
#pragma comment(lib,"libzip.lib")//解压压缩包
//传参：压缩包路径、目标文件夹路径
void DriverList::unZip(const char* zipName, const char* dirName) {int iErr = 0;struct zip* zipfile = NULL;struct zip_file* entries = NULL;struct zip_stat stat;zip_int64_t i64Num = 0;zip_int64_t i64Count = 0;int iRead = 0;int iLen = 0;char buf[1024];memset(&stat, 0, sizeof(stat));memset(buf, 0, sizeof(buf));zipfile = zip_open(zipName, ZIP_CHECKCONS, &iErr);if (!zipfile){printf("zip open failed:%d\n", iErr);exit(EXIT_FAILURE);}//get how many entrrites in archivei64Num = zip_get_num_entries(zipfile, 0);for (i64Count = 0; i64Count < i64Num; i64Count++){iLen = 0;if (zip_stat_index(zipfile, i64Count, 0, &stat) == 0){printf("the file name is:%s\n", stat.name);}entries = zip_fopen_index(zipfile, i64Count, 0);if (!entries){printf("fopen index failed\n");goto End;}//create the original filechar filePath[MAX_PATH]{ 0 };strcpy(filePath, dirName);strcat(filePath, "/");strcat(filePath, stat.name);FILE* fp = fopen(filePath, "wb+");if (!fp){printf("create local file failed\n");goto End;}while (iLen < stat.size){iRead = zip_fread(entries, buf, 1024);if (iRead < 0){printf("read file failed\n");fclose(fp);goto End;}fwrite(buf, 1, iRead, fp);iLen += iRead;}fclose(fp);}End:zip_close(zipfile);
}
