Testing POST Request with protobuf --> send binary payload

[zera...@freenet.de]

Hello,

I already implemented with spring boots REST services, whichs allows me to GET the encoded payload in x-protobuf with the CURL command:

curl -X GET --header "Accept: application/x-protobuf" "[...URL...]" | protoc --decode_raw

I'll see the correct result in plaintext. The generated *.java class based on my *.proto seems to work fine. 

Now I'm struggling on a really simple point: I'm not able to send my binary protobuf stream via CURL to my POST-service. I have a simple message file with human-readable JSON content (--> UploadLogs.payload) and my protofile. Based on this, I want to generate the the binary protobuf payload and want to POST-call the REST service. Do you have an idea, how I can handle this? :)

Something like...

curl -X POST --data-binary @UploadLogs.payload --header "Accept: application/x-protobuf" "[...URL...]"

Maybe, I have to save the binary protobuf content with protoc --encode first in a separate file, and then call CURL with this new filename with the --data-binary parameter. Right now, I'm not able to store the protobuf payload based on the JSON file in a new separate file. 

Any help would be really appreciated! :)

Kind regards

Emily

This seems like it should be doable. Is there some reason you can't store the payload in binary format in a separate file?
