i have the following code for grpc:
val port = 9090val metadata = Metadata()metadata.put(Metadata.Key.of("Authorization", Metadata.ASCII_STRING_MARSHALLER), "Bearer eyJhbGciOiJSUzI1NiIsInR5cCIgOiAiSldUIiwia2lkIiA6ICJCTzdIZWwwSkRpc0YxR1JWd21oZmRxanpJZFdLS1VlX3htWEVkTndsNzZ3In0.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.P3uIa7S36cLN3w49yeeyf0Ddd5nibQuE_nzdJzBOQewjIBwqGPTsPHvtsa59Ldnc_enYbjxzURoJ5ho-FeQZwuIEb2iM5yB_UrzPDFgZbsUBwNH3-Efdv1W-7lS-4XLne4BmT-7fP-H6EFjVTD8pDArSeX53O6fXn79VJJaEFYpZ7CGqEc2NoBmi8dhKpzcJ7ii1-kkPm3sSOiNwjDannXTXy8hA-INuAyE_dZu7souHN_IJL6e7yw8ueeo-eXDPwjB9QxAR09aRfFNGkuzgghPzeIsJAeaf8GLRdNDzF4YB6klaCPOM19-FNuD7P3pdLfAKqD-Dxa2jPl8jjODRow")metadata.put(Metadata.Key.of("txn-mgr-flag", Metadata.ASCII_STRING_MARSHALLER), "false")val channel = ManagedChannelBuilder .intercept(MetadataUtils.newAttachHeadersInterceptor(metadata)) .forAddress("grpc.friday.fastek.ph", port) .useTransportSecurity() .build()try {val client = FastekBeepClient(channel)client.stmBalance()i added the headers this way...
val metadata = io.grpc.Metadata()metadata.put(Metadata.Key.of("authorization", Metadata.ASCII_STRING_MARSHALLER),"Bearer token...")then call the rpc method this way..
client.stmBalance(intialRequest))take note that i needed to add authorization as header as it was needed
Im still getting UNAVAILABLE status but when i tried it on postman it was working..
