c++代码：src.cpp
#include <string> struct World { World(std::string a_msg) : msg(a_msg) {} std::string greet() const { return msg; } std::string msg; }; python转换代码:src4py.cpp
#include <boost/python.hpp> #include "src.cpp" using namespace boost::python; struct World_picklers : pickle_suite { static tuple getinitargs(World const& w) { return make_tuple(w.greet()); } }; BOOST_PYTHON_MODULE(test) { class_<World>("World", init<std::string>()) .def("greet", &World::greet) .def_pickle(World_picklers()) //请关注这行的函数名，是固定的 ; }
python调用代码:test.py
import test import pickle a = test.World("haha") pickle.dump(a,open("my_world","w")) print "create pickle file(my_world)" print "load from pickle file(my_world)" b = pickle.load(open("my_world","r")) print b.greet()
