POCO 在 Windows 中默认是定义了 POCO_WIN32_UTF8
#if defined (POCO_WIN32_UTF8) std::wstring utf16Path; UnicodeConverter::toUTF16(path, utf16Path); _handle = CreateFileW(utf16Path.c_str(), access, shareMode, NULL, creationDisp, flags, NULL); #else _handle = CreateFileA(path.c_str(), access, shareMode, NULL, creationDisp, flags, NULL); #endif
Poco::Path file(filename); // filename 不是 utf16 编码 file.makeFile(); Poco::Path dest(_outDir, file); // _outDir 是 utf16 编码 dest.makeFile(); ... Poco::FileOutputStream out(dest.toString()); // 这时候整个文件路径是不正确的 ZipInputStream inp(zipStream, hdr, false); Poco::StreamCopier::copyStream(inp, out); out.close();
只要把 filename 转换成 UTF16 就可以了。
在 Poco::Path file(filename); 之前加上这段代码,整个文件路径就正确了:
std::string dest_filename = fileName; #if defined (POCO_WIN32_UTF8) std::wstring utf16_name = s2ws(fileName); UnicodeConverter::toUTF8(utf16_name, dest_filename); #endif Poco::Path file(dest_filename);
std::wstring Decompress::s2ws(const std::string& s) { setlocale(LC_ALL, "chs"); const char* _Source = s.c_str(); size_t _Dsize = s.size() + 1; wchar_t *_Dest = new wchar_t[_Dsize]; wmemset(_Dest, 0, _Dsize); mbstowcs(_Dest,_Source,_Dsize); std::wstring result = _Dest; delete []_Dest; setlocale(LC_ALL, "C"); return result; }
