Unable to read BOOLEAN value from pulsar message
Expected behavior
Sending pulsar message with value type Boolean (wrapper class) in java with RSA encryption enabled but unable to read it at consumer side with go client. correct boolean value should be received provided correct decryption keys.
Actual behavior
value is always empty and not sure what will be the right schema type for boolean value.
Steps to reproduce
Here I am writing producer in go (integration test) instead of JAVA. producer code:
keyReader := crypto.NewFileKeyReader('PROVIDE PATH TO PUBLIC KEY', 'PROVIDE PATH TO PRIVATE KEY')
producer, _ := client.CreateProducer(pulsar.ProducerOptions{
Topic: "some-topic",
Encryption: &pulsar.ProducerEncryptionInfo{
KeyReader: keyReader,
ProducerCryptoFailureAction: crypto.ProducerCryptoFailureActionFail,
Keys: []string{"client-rsa.pem"},
},
})
msgId, err := producer.Send(ctx, &pulsar.ProducerMessage{
Key: "abc-key",
Value: true,
})
Consumer code:
keyReader := crypto.NewFileKeyReader('PROVIDE PATH TO PUBLIC KEY', 'PROVIDE PATH TO PRIVATE KEY')
options := pulsar.ConsumerOptions{
Topic: topic-name,
Type: pulsar.Shared,
MessageChannel: channel,
SubscriptionInitialPosition: pulsar.SubscriptionPositionEarliest,
Decryption: &pulsar.MessageDecryptionInfo{
KeyReader: keyReader,
ConsumerCryptoFailureAction: crypto.ConsumerCryptoFailureActionFail,
},
}
How to use schematype for BOOLEAN value? I checked the https://github.com/apache/pulsar-client-go/blob/master/pulsar/schema.go but it is unclear for boolean value. any help would be appreciated.
Workaround/solution: Currently I am reading payload directly, checking if it is not nil and then converting it to bool.
payload := msg.Payload()
if payload != nil {
value := payload[0] != 0
}
System configuration
Pulsar version: 3.0.x
-
Pulsar-client-go not supports BOOLEAN schema yet

You didn't set a
Schemafor the producer and use theValuefield, theValuefield needs aSchemato encode it intoPayload([]byte). If theSchemanot set, the message you sent will has an empty body. So you can't read the message payload when you consuming messages. In this condition, you can
producer.send(ctx, &ProducerMessage{
Key: "abc-key",
Payload: ture ? []byte{1} : []byte{0},
})
I created a PR to introduce BooleanSchema: https://github.com/apache/pulsar-client-go/pull/1108
