Thank very much.
I've found the reason, it's because the serialized data the binary data
instead of text, so when stored into a char array, it somehow won't appear
textually, but in fact it is there.
i'm sorry to have disturbed the forum with such silly question.

std::string(buf) will be initialized with null terminated string. If the
serialized data contains 0, it will be truncated in the string.
I think you should use std::string(buf, n)
