ServiceNow Data にSQL を使ってAnypoint からデータ連携

CData Mule Connector for ServiceNow を使って、ServiceNow data のJSON エンドポイントを作成するシンプルなMule アプリケーションを作成。

CData Mule Connector for ServiceNow は、ServiceNow data をMule アプリケーションから標準SQL でのreadを可能にします。コネクタを使うことで、Mule アプリケーションでServiceNow data のバックアップ、変換、レポート、および分析を簡単に行えます。

This article demonstrates how to use the CData Mule Connector for ServiceNow inside of a Mule project to create a Web interface for ServiceNow data. The application created allows you to request ServiceNow data using an HTTP request and have the results returned as JSON. The exact same procedure outlined below can be used with any CData Mule Connector to create a Web interface for the 210+ available data sources.

  1. Create a new Mule Project in Anypoint Studio.
  2. Add an HTTP Connector to the Message Flow.
  3. Configure the address for the HTTP Connector.
  4. Add a CData ServiceNow Connector to the same flow, after the HTTP Connector.
  5. Create a new Connection (or edit an existing one) and configure the properties to connect to ServiceNow (see below). Once the connection is configured, click Test Connection to ensure the connectivity to ServiceNow.

    ServiceNow はOAuth 2.0 認証標準を利用しています。OAuth を使って認証するには、ServiceNow にOAuth アプリを登録してOAuthClientId を取得しなければなりません。OAuth 値の他に、Instance、User、およびPassword の指定が必要です。

    OAuth 認証を介した接続について詳しくは、ヘルプドキュメントの「OAuth 認証の使用」を参照してください。

  6. Configure the CData ServiceNow Connector.
    1. Set the Operation to 'Select with Streaming'.
    2. Set the Query type to Dynamic.
    3. Set the SQL query to SELECT * FROM #[message.inboundProperties.'http.query.params'.get('table')] to parse the URL parameter table and use it as the target of the SELECT query. You can customize the query further by referencing other potential URL parameters.
  7. Add a Transform Message Component to the flow.
    1. Map the Payload from the input to the Map in the output.
    2. Set the Output script to the following to convert the payload to JSON:
      %dw 1.0
      %output application/json
      ---
      payload
              
  8. To view your ServiceNow data, navigate to the address you configured for the HTTP Connector (localhost:8081 by default) and pass a table name as the table URL parameter: http://localhost:8081?table=incident
    The incident data is available as JSON in your Web browser and any other tools capable of consuming JSON endpoints.

At this point, you have a simple Web interface for working with ServiceNow data (as JSON data) in custom apps and a wide variety of BI, reporting, and ETL tools. Download a free, 30 day trial of the Mule Connector for ServiceNow and see the CData difference in your Mule Applications today.
