Thanks Michael Lumish. Can you please confirm whether the below code is
correct. I am worried whether there is some asynchronous problem. How to
use auth_creds for the next function -
grpc.credentials.combineChannelCredentials(ssl_creds,
auth_creds) ?
function generateMetadata(params, callback) {
var metadata = new grpc.Metadata();
metadata.add('authorization', response.access_token);
console.log(metadata); // *Prints second*
callback(null,metadata);
}
var auth_creds =
grpc.credentials.createFromMetadataGenerator(generateMetadata);
console.log(auth_creds); // *Prints first*
var combined_creds = grpc.credentials.combineChannelCredentials(ssl_creds,
auth_creds);
var clientnew = new proto.Gateway('localhost:50001',combined_creds);
var cmd = {};
var call = clientnew.listAcousticSystems(cmd);
call.on('data', function(systems) {
console.log(systems);
});
