Google Search Results にSQL を使ってAnypoint からデータ連携

CData Mule Connector for Google Search を使って、Google Search results 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 Google Search は、Google Search results 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Google Search results 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 Google Search inside of a Mule project to create a Web interface for Google Search results. The application created allows you to request Google Search results 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 220+ 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 Google Search 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 Google Search (see below). Once the connection is configured, click Test Connection to ensure the connectivity to Google Search.

    Google カスタム検索エンジンを使って検索するには、CustomSearchId およびAPIKey 接続プロパティが必要です。

    CustomSearchId を取得するには、Google カスタム検索エンジンにサインインして検索エンジンを新規作成します。

    APIKey を取得するには、Google API Console でカスタム検索API を有効にします。

  6. Configure the CData Google Search 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 Google Search results, 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=VideoSearch
    The VideoSearch 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 Google Search results (as JSON data) in custom apps and a wide variety of BI, reporting, and ETL tools.
