windows中文操作系统下,vs的c++项目默认编码是GB2312
python默认是utf-8编码
最好在c++程序顶上加:
#pragma execution_character_set("GB2312")
c++中的字符串一定就是gbk编码
传入python前要做编码转换
准备一个gbk转utf8的函数,如下(网上的):
string GbkToUtf8(const char* src_str) { int len = MultiByteToWideChar(CP_ACP, 0, src_str, -1, NULL, 0); wchar_t* wstr = new wchar_t[len + 1]; memset(wstr, 0, len + 1); MultiByteToWideChar(CP_ACP, 0, src_str, -1, wstr, len); len = WideCharToMultiByte(CP_UTF8, 0, wstr, -1, NULL, 0, NULL, NULL); char* str = new char[len + 1]; memset(str, 0, len + 1); WideCharToMultiByte(CP_UTF8, 0, wstr, -1, str, len, NULL, NULL); string strTemp = str; if (wstr) delete[] wstr; if (str) delete[] str; return strTemp; }
示例性代码:
#pragma execution_character_set("GB2312") #include <stdlib.h> #include <Windows.h> #include <iostream> #include <Python.h> #include <string> #include <atlstr.h> using namespace System; using namespace System::Runtime::InteropServices; using namespace System::Collections::Generic; using namespace System::Diagnostics; using namespace System::Threading; using namespace std; int main() { const char* name = "东方红1号"; Py_Initialize();//初始化python PyRun_SimpleString("import sys"); PyRun_SimpleString("sys.path.append('./')"); PyObject* pModule = PyImport_ImportModule("hello"); PyObject* pFunc1 = PyObject_GetAttrString(pModule, "sayhello"); PyObject* pArgs = PyTuple_New(1); PyObject* pV1 = Py_BuildValue("s", GbkToUtf8(name).c_str()); PyTuple_SetItem(pArgs, 0, pV1); PyObject* result = PyObject_CallObject(pFunc1, pArgs); Py_Finalize(); return 0;
