msgpack应用-c++与Python结合

1.data struct

struct DT { std::string name; int id; DT():name("123"),id(0){ } MSGPACK_DEFINE(name, id); };

2.encode

msgpack::sbuffer buffer_; msgpack::packer<msgpack::sbuffer> pack_(&buffer_); pack_.pack_map(4); pack_.pack("key_1"); pack_.pack("value_1"); pack_.pack("key_2"); pack_.pack("value_1"); pack_.pack("key_3"); pack_.pack(3); std::vector<DT> ts; ts.push_back(DT()); ts.push_back(DT()); ts.push_back(DT()); pack_.pack("DT"); pack_.pack(ts);

3.decode

4.python 压码解码 4.1 encode

dt = {b'key': b'value', b'key_3': 3, b'DT': [['12e', 1254], ['aa3', 1254]]} pack = msgpack.packb(dt)

4.2 decode

unpacker = msgpack.unpackb(BUFFER)#BUFFER接收到的buffer
