Decoding data to type with --decode
Similarly, we have the --decode
flag, which takes a binary and returns the data into text format. Once again, here, this flag is mostly for debugging and, in our case, for learning.
Now, remember that we already did the opposite of decode
. This means that we will be able to take the output of encode
, redirect it to decode
, and we should get our input back. This would look like the following:
input > encode > decode > input
So, let us start with the encode
part. We are already familiar with it; we can just execute the following command:
$ cat user.txtpb | protoc --encode=User user.proto
Or, we could execute this command:
$ Get-Content user.txtpb | protoc --encode=User user.proto
We will redirect the standard output of these commands to a file for convenience. We can do this by redirecting to a file, like so:
$ … > user.bin
With that, we can now see how to use --decode
. It is very similar to --encode
. It takes...
