[protobuf] How to use protoc with Node http - and in a Javascript client

[Jorg Janke]

I am trying to send/receive protoc with Node and in a Javascript client.

With the Node code below, I get: TypeError: First argument must be a string 
or Buffer
What am I missing?

The actual server is Java based.

Thanks!
Jorg

:

var postData = protoRequest.serializeBinary(); // Uint8Array

var options = {
    protocol: 'https:',
    hostname: 'xxx',
    port: 443,
    path: '/xxx',
    method: 'POST',
    headers: {
        'Content-Type': 'application/application/x-google-protobuf',
        'Content-Length': Buffer.byteLength(postData)
    }
};

var req = https.request(options, function(res) {
    res.on('data', function(chunk) {
        var responseMessage = ProtoResponse.deserializeBinary(chunk);
        console.log("Response", responseMessage);

    });
});
req.write(postData);
req.end();
