解决c++调用python中文乱码问题
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：
#pragmaexecution_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）：
stringGbkToUtf8(constchar*src_str)
{
intlen=MultiByteToWideChar(CP_ACP,0,src_str,-1,NULL,0);
wchar_t*wstr=newwchar_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=newchar[len+1];
memset(str,0,len+1);
WideCharToMultiByte(CP_UTF8,0,wstr,-1,str,len,NULL,NULL);
stringstrTemp=str;
if(wstr)delete[]wstr;
if(str)delete[]str;
returnstrTemp;
}
示例性代码：
#pragmaexecution_character_set("GB2312")
#include
#include
#include
#include
#include
#include
usingnamespaceSystem;
usingnamespaceSystem::Runtime::InteropServices;
usingnamespaceSystem::Collections::Generic;
usingnamespaceSystem::Diagnostics;
usingnamespaceSystem::Threading;
usingnamespacestd;
intmain()
{
constchar*name="东方红1号";
Py_Initialize();//初始化python
PyRun_SimpleString("importsys");
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();
return0;
