很简洁很给力的文章。

extern "C" bool RunFyFuntion(char *strFilename, char *strModuleName, char *strFunctionName){PyObject *pParams = NULL;PyObject *pModuleOld = NULL;PyObject *pModule =NULL;PyObject *pName = NULL;PyObject *pResult = NULL;PyObject *pDict = NULL; PyObject *pFunc = NULL;bool bResult = false;class PyThreadStateLock PyThreadLock;pName = PyString_FromString(strFilename);pModuleOld = PyImport_Import(pName);if(!pModuleOld){QDLogs.SendMsg(LOG_OUTPUT_ERROR_TEAM, "%s file read error", strFilename);goto last;}pModule = PyImport_ReloadModule(pModuleOld);if(!pModule){QDLogs.SendMsg(LOG_OUTPUT_ERROR_TEAM, "%s file read error", strFilename);goto last;}pDict = PyModule_GetDict(pModule);// 获得函数名pFunc = PyDict_GetItemString(pDict, strFunctionName);if (!pFunc || !PyCallable_Check(pFunc)){QDLogs.SendMsg(LOG_OUTPUT_ERROR_TEAM, "%s function read error", strFunctionName);goto last;}// 设置参数pParams = PyTuple_New(2);PyTuple_SetItem(pParams, 0, Py_BuildValue("s", "abc"));PyTuple_SetItem(pParams, 1, Py_BuildValue("i", 1));// 执行函数pResult = PyObject_CallObject(pFunc, pParams);if(pResult == Py_True){bResult = true;}else{QDLogs.SendMsg(LOG_OUTPUT_ERROR_TEAM, "%s function run error", strFunctionName);goto last;}last:Py_XDECREF(pFunc);Py_XDECREF(pDict);Py_XDECREF(pParams);Py_XDECREF(pModuleOld);Py_XDECREF(pModule);Py_XDECREF(pName);Py_XDECREF(pResult);return bResult;}
