Question

我正在尝试使用融合客户端注册表中的 avro 模式从 kafka avro 主题中读取数据。我正在使用 io.confluent 库版本 5.4.1。这是gradle文件中的入口

    compile (group: 'io.confluent', name: 'kafka-avro-serializer', version: '5.4.1') {
        exclude group: 'org.apache.avro', module: 'avro'
    }

我收到以下错误。

Caused by: io.confluent.kafka.schemaregistry.client.rest.exceptions.RestClientException: Unauthorized; error code: 401

public PCollection<KV<String, GenericRecord>> apply(Pipeline p) {
       ConfluentSchemaRegistryDeserializerProvider<GenericRecord> valDeserializerProvider =
                ConfluentSchemaRegistryDeserializerProvider.of(params.schemaUrl, "topic-value");

        PCollection<KafkaRecord<String, GenericRecord>> records = p.apply("GetDataFromKafka", KafkaIO.<String, GenericRecord>read()
                .withBootstrapServers(params.apiHost)
                .withTopics("topic")
                .withConsumerConfigUpdates(params.getConsumerProps())
                .withKeyDeserializer(StringDeserializer.class)
                .withValueDeserializer(valDeserializerProvider)
                .commitOffsetsInFinalize());

        return records.apply("TopicAndDataInput", MapElements.via(new SimpleFunction<KafkaRecord<String, GenericRecord>, KV<String, GenericRecord>>() {
            @Override
            public KV<String, GenericRecord> apply(KafkaRecord<String, GenericRecord> input) {
                String topic = input.getTopic();
                GenericRecord data = input.getKV().getValue();
                return KV.of(topic, data);
            }
        }));
    }

我在这里错过了什么？有人可以指出我正确的方向。提前致谢。

这是获取消费者属性的函数

    public Map<String, Object> getConsumerProps() {
        Map<String, Object> props = new HashMap<> ();

        props.put("group.id", groupId);
        props.put("auto.offset.reset", "earliest");
        props.put("retry.backoff.ms",500);
        props.put("max.partition.fetch.bytes", 8388608);
        props.put("basic.auth.credentials.source", "USER_INFO");
        props.put("basic.auth.user.info", "registry_key:secret");
        props.put("ssl.endpoint.identification.algorithm","https");
        props.put("security.protocol","SASL_SSL");
            
        props.put("sasl.jaas.config","org.apache.kafka.common.security.plain.PlainLoginModule required username='"+ apiKey +"' password='" + apiSecret +"';");
        props.put("sasl.mechanism","PLAIN");
        return props;
    }

也尝试了以下道具，但仍然得到相同的未授权错误。

props.put("basic.auth.credentials.source", "USER_INFO");
props.put("schema.registry.basic.auth.user.info", "<registry key>:<value>");
props.put("schema.registry.url", schemaUrl);

似乎您应该将特定的架构注册表项和秘密添加为

props.put("schema.registry.basic.auth.user.info", "<SCHEMA_REGISTRY_API_KEY>:<SCHEMA_REGISTRY_API_SECRET>");
