[questions]Envelope::MergeFromCodedStream return some unknow_data

[lfjking]

The protobuff version is 2.6.0. After starting the service, After reading the data from "forward localabstract:stfservice": buff, len. Envelope lope; if (lope.ParseFromArray(buff, len)){ Dg("Event Type:%d \n", lope.type()); }

ParseFromArray always returns false. Is the buff length a problem? How do I adjust?

---

ok, ParseFromArray using from the group data. the non-group data, using MergeFromCodedStream. now , I from the MergeFromCodedStream get the type . but, also have some buffer can't Parse, alway, the data size 44.

I don't know it is my lost or it is the Envelope get the non-group data.

Can you provide some examples of receiving data of unknown length and parsing successfully?

I get the info for each packet form remote:

I don't know why...... I use the fun :ParseFromArray to parse the packet. There is no operation on my phone, why do I keep receiving this message?

[lfjking]

Now, I changed my code like it:

    Envelope &lope = mEnvelope;
        bool isok = false;
        io::CodedInputStream stream(data, len);
        while (!stream.ConsumedEntireMessage())
        {
            if (lope.MergeFromCodedStream(&stream)){
                ParseMessage(lope);
                isok = true;
            }
        }
        if (!isok){
            Dg("forward get un_know buffer(%d):\n", len);
            for (size_t i = 0; i < len; i++){
                char c = data[i];
                if (c > 31 && c < 127){
                    Dg("%c", c);
                }
                else{
                    Dg("x%02x\\", c);
                }
            }
            Dg("\n");
        }

I use the MergeFromCodedStream. It can parse more data from the received to the data. But there are still parts of the data that cannot be parsed. All data has to go through here, so there is no data loss.

As you can see from the wire message, the data information that cannot be parsed should be: EVENT_BATTERY

[lfjking]

It's exploding! After r rebooting my phone, I was able to parse the EVENT_BATTERY data.

Event Type:EVENT_BATTERY(14) 
Battery:health:good
Battery:level:100
Battery:scale:100
Battery:source:usb
Battery:status:charging

What an experience!
