7.3. 在 Service Registry 中注册 schema

在以适当的格式（如 Apache Avro）定义了模式后，您可以将模式添加到 Service Registry。

您可以使用以下方法添加模式：

在注册了 schema 前，客户端应用程序无法使用 Service Registry。

Service Registry web 控制台

安装 Service Registry 后，您可以从 ui 端点连接到 Web 控制台：

http://MY-REGISTRY-URL/ui

在控制台中，您可以添加、查看和配置模式。您还可以创建阻止将无效内容添加到 registry 的规则。

curl 命令示例

 curl -X POST -H "Content-type: application/json; artifactType=AVRO" \
   -H "X-Registry-ArtifactId: share-price" \ 1
   --data '{
     "type":"record",
     "name":"price",
     "namespace":"com.example",
     "fields":[{"name":"symbol","type":"string"},
     {"name":"price","type":"string"}]}'

Maven 插件示例

<plugin>
  <groupId>io.apicurio</groupId>
  <artifactId>apicurio-registry-maven-plugin</artifactId>
  <version>${apicurio.version}</version>

      <execution>

使用制作者客户端示例进行配置

String registryUrl_node1 = PropertiesUtil.property(clientProperties, "registry.url.node1",
    "https://my-cluster-service-registry-myproject.example.com/apis/registry/v2"); 1
try (RegistryService service = RegistryClient.create(registryUrl_node1)) {
    String artifactId = ApplicationImpl.INPUT_TOPIC + "-value";
    try {
        service.getArtifactMetaData(artifactId); 2
    } catch (WebApplicationException e) {
        CompletionStage <ArtifactMetaData> csa = service.createArtifact(
            "AVRO",
            artifactId,
            new ByteArrayInputStream(LogInput.SCHEMA$.toString().getBytes())
        );
        csa.toCompletableFuture().get();
    }
}
