Hi,
I am trying to serialize a protocol buffers message into a string that
is contained in another protocol buffer. I am doing the serialization
on the C++ side.
// This is the outer protocol buffer
message Measurement {
required string id = 1;
optional string meas_rec_str = 2;
}
Measurement m;
// This is the protocol buffer message I want to serialize into a
string and store inside meas_rec.
message MeasRec {
optional int id = 1;
}
To serialize the MeasRec message, I am doing:
MeasRec meas_rec;
meas_rec.set_id(100);
char* str_buf;
str_buf = new char[meas_rec.ByteSize()];
string str = str_buf;
meas_rec.SerializeToString(&str);
m.set_meas_rec_str(str);
However, when I do this, I encounter the following error on the C++
side:
libprotobuf ERROR google/protobuf/wire_format.cc:1059] Encountered
string containing invalid UTF-8 data while serializing protocol
buffer. Strings must contain only UTF-8; use the 'bytes' type for raw
bytes.
how do I serialize meas_rec into "bytes" instead?
Also, once I have it on the Java side, how do I deserialize?
would I use parseFrom(byte[] data) ?
Thanks,
Paul
