没人帮忙，只能自己搞定了
方法是导出ZipUtils，在ZipUtils里面添加uncompressDir的方法给lua用
bool ZipUtils::uncompressDir(char* filename, char* destPath) { if (filename == NULL || destPath == NULL) { CCLOG(“source zip is null or dest path is null!”); return false; } // Open the zip file std::string outFileName = filename; unzFile zipfile = unzOpen(outFileName.c_str()); if (!zipfile) { CCLOG(“can not open downloaded zip file %s”, outFileName.c_str()); return false; } // Get info about the zip file unz_global_info global_info; if (unzGetGlobalInfo(zipfile, &global_info) != UNZ_OK) { CCLOG(“can not read file global info of %s”, outFileName.c_str()); unzClose(zipfile); return false; } const int BUFFER_SIZE = 8192; const int MAX_FILENAME = 512; // Buffer to hold data read from the zip file char readBuffer; CCLOG(“start uncompressing”); // Loop to extract all files. uLong i; for (i = 0; i < global_info.number_entry; ++i) { // Get info about current file. unz_file_info fileInfo; char fileName; if (unzGetCurrentFileInfo(zipfile, &fileInfo, fileName, MAX_FILENAME, NULL, 0, NULL, 0) != UNZ_OK) { CCLOG(“can not read file info”); unzClose(zipfile); return false; } std::string storagePath = destPath; std::string fullPath = storagePath + fileName; // Check if this entry is a directory or a file. const size_t filenameLength = strlen(fileName); if (fileName == ‘/’) { // get all dir std::string fileNameStr = std::string(fileName); size_t position = 0; while ((position = fileNameStr.find_first_of("/", position)) != std::string::npos) { std::string dirPath = storagePath + fileNameStr.substr(0, position); // Entry is a direcotry, so create it. // If the directory exists, it will failed scilently. if (!createDirectory(dirPath.c_str())) { CCLOG(“can not create directory %s”, dirPath.c_str()); //unzClose(zipfile); //return false; } position++; } } else { // Entry is a file, so extract it. // Open current file. if (unzOpenCurrentFile(zipfile) != UNZ_OK) { CCLOG(“can not open file %s”, fileName); unzClose(zipfile); return false; } // Create a file to store current file.
