先上python代碼:
# call.py
def test():
print 'hello world'
def add(a,b):
return a + b
再上c代碼
#include <stdio.h>
#include <stdlib.h>
#include <Python.h>
int main(int argc, char *argv[])
{
Py_Initialize();
if(!Py_IsInitialized())
{
return -1;
}
PyRun_SimpleString("import sys");
PyRun_SimpleString("sys.path.append('./')");
PyObject* pName;
PyObject* pModule;
PyObject* pDict;
PyObject* pFunc;
pName = PyString_FromString("call");
pModule = PyImport_Import(pName);
if(!pModule)
{
printf("can't find call.py");
getchar();
return -1;
}
pDict = PyModule_GetDict(pModule);
if(!pDict)
{
return -1;
}
{
pFunc = PyDict_GetItemString(pDict,"test");
if(!pFunc || !PyCallable_Check(pFunc))
{
printf("can't find function [test]");
getchar();
return -1;
}
PyObject_CallObject(pFunc,0);
}
{
pFunc = PyDict_GetItemString(pDict,"add");
if(!pFunc || !PyCallable_Check(pFunc))
{
printf("can't find function [test]");
getchar();
return -1;
}
PyObject* args = PyTuple_New(2);
PyTuple_SetItem(args,0,Py_BuildValue("l",3));
PyTuple_SetItem(args,1,Py_BuildValue("l",4));
PyObject *pAdded = PyObject_CallObject(pFunc,args);
int ret = PyInt_AsLong(pAdded);
printf("add value:%d\n",ret);
Py_DECREF(args);
}
Py_DECREF(pName);
Py_DECREF(pDict);
Py_DECREF(pModule);
Py_Finalize();
system("PAUSE");
return 0;
}
就不做解釋了
不過如何從字符串中載入模塊？
