连接 ServiceNow 数据源

要创建 ServiceNow 数据源，请使用适用于 Amazon Bedrock 构建时终端节点的代理发送CreateDataSource请求。以下 AWS Command Line Interface 示例创建了一个 ServiceNow 数据源。有关每个字段的描述，请参阅随后的连接器参数参考。

aws bedrock-agent create-data-source \
 --name "ServiceNow-connector" \
 --knowledge-base-id "your-knowledge-base-id" \
 --data-source-configuration file://servicenow-managed-connector.json

该servicenow-managed-connector.json文件包含以下内容：

{
    "type": "MANAGED_KNOWLEDGE_BASE_CONNECTOR",
    "managedKnowledgeBaseConnectorConfiguration": {
        "connectorParameters": {
            "type": "SERVICENOW",
            "connectorType": "SERVICENOW",
            "version": "1",
            "connectionConfiguration": {
                "secretArn": "arn:aws:secretsmanager:us-west-2:123456789012:secret:bedrock-servicenow-creds",
                "authType": "OAUTH2",
                "hostUrl": "https://INSTANCE.service-now.com"
            },
            "dataEntityConfiguration": {
                "crawlKnowledgeArticles": true,
                "crawlServiceCatalogs": true,
                "crawlKnowledgeArticleAttachments": true,
                "crawlServiceCatalogAttachments": true,
                "crawlInactiveServiceCatalogItems": false,
                "crawlPublicKnowledgeArticlesOnly": false
            },
            "filterConfiguration": {
                "knowledgeArticleFilter": {
                    "inclusionKnowledgeBaseSysIds": ["optional-kb-sys-id"],
                    "inclusionKnowledgeArticleCategorySysIds": []
                },
                "serviceCatalogFilter": {
                    "inclusionServiceCatalogSysIds": [],
                    "inclusionServiceCatalogCategorySysIds": []
                },
                "maxFileSizeInMegaBytes": "500"
            }
        }
    }
}

这些dataEntityConfiguration字段控制连接器爬行哪些实体。该filterConfiguration字段是可选的；使用它可以将抓取范围限定为特定的知识库、知识文章类别或服务目录，并设置最大文件大小。如果没有过滤器，连接器会抓取所有活跃的知识文章和服务目录项目。

对于托管知识库，CreateDataSource是异步的：操作完成后，数据源状态从过渡CREATING到AVAILABLE。
