コネクタのインストール 後、Azure DevOps 内のデータのデータソースに接続して作成できます。

データソースの設定

データに接続するには、次の手順を実行してください：

1. 接続 | To a Server で詳細をクリックします。
2. Azure DevOps by CData というデータソースを選択します。
3. 接続に必要な情報を入力します。
4. サインインをクリックします。
5. 必要に応じて、データベースおよびスキーマを選択して利用可能なテーブルとビューを確認できます。

Connection Builder の使用

connector は、代表的な接続プロパティをTableau 内で直接利用できるようにします。 しかし、より高度な設定が必要な場合や接続に関するトラブルシューティングが必要な場合には、使いにくいことがあります。 connector には、Tableau の外で接続を作成してテストできる、独立したConnection Builder が付属しています。

Connection Builder にアクセスする方法は2つあります。

• Windows では、スタートメニューのCData Tableau Connector for Azure DevOps フォルダの下にあるConnection Builder というショートカットを使用します。
• また、ドライバーのインストールディレクトリに移動し、lib ディレクトリで.jar ファイルを実行することによってもConnection Builder を開始できます。

Connection Builder では、接続プロパティに値を設定し、接続テストをクリックしてその動作を確認できます。 また、クリップボードにコピーボタンを使用して、接続文字列をコピーすることもできます。 この接続文字列は、Tableau 内のconnector 接続ウィンドウにあるConnection String オプションに指定できます。

Azure DevOps への接続

To connect to your Azure DevOps account, specify Organization, the name of your Organization in the account, by navigating to Profile > Organizations.

For example, Organization=MyAzureDevOpsOrganization;

NOTE : Along with Organization you must provide ProjectId when connecting to Analytics schema.

Azure DevOps への認証

Basic

You can connect to your Azure DevOps account by providing the Organization and PersonalAccessToken. To generate a perosonal access token, log in to your Azure DevOps Organization account and navigate to Profile > Personal Access Tokens > New Token. The generated token is displayed.

Azure AD

Azure AD is a connection type that leverages OAuth to authenticate. OAuth requires the authenticating user to interact with Azure DevOps using an internet browser. The connector facilitates this in several ways as described below. Set AuthScheme to AzureAD and Organization to the name of your Azure DevOps organization. The rest of the AzureAD flows assume that you set these two properties.

Desktop Applications

CData provides an embedded OAuth application that simplifies OAuth desktop Authentication. Alternatively, you can create a custom OAuth application. See カスタムOAuth アプリケーションの作成 for information about creating custom applications and reasons for doing so.

For authentication, the only difference between the two methods is that you must set two additional connection properties when using custom OAuth applications.

After setting the following connection properties, you are ready to connect:

• InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to avoid repeating the OAuth exchange and manually setting the OAuthAccessToken.
• OAuthClientId: (custom applications only) Set this to the client Id in your application settings.
• OAuthClientSecret: (custom applications only) Set this to the client secret in your application settings.
• CallbackURL: Set this to the Redirect URL in your application settings.

When you connect the connector opens the OAuth endpoint in your default browser. Log in and grant permissions to the application. The connector then completes the OAuth process:

1. Extracts the access token from the callback URL and authenticates requests.
2. Obtains a new access token when the old one expires.
3. Saves OAuth values in OAuthSettingsLocation that persist across connections.

Headless Machines

To configure the driver to use OAuth with a user account on a headless machine, you need to authenticate on another device that has an internet browser.

1. Choose one of these two options:
   • Option 1: Obtain the OAuthVerifier value as described in "Obtain and Exchange a Verifier Code" below.
   • Option 2: Install the connector on another machine and transfer the OAuth authentication values after you authenticate through the usual browser-based flow, as described in "Transfer OAuth Settings" below.

2. Then configure the connector to automatically refresh the access token from the headless machine.

Option 1: Obtain and Exchange a Verifier Code

To obtain a verifier code, you must authenticate at the OAuth authorization URL.

Follow the steps below to authenticate from the machine with an internet browser and obtain the OAuthVerifier connection property.

1. Choose one of these options:
   • If you are using the Embedded OAuth Application click Azure DevOps OAuth endpoint to open the endpoint in your browser.
   • If you are using a custom OAuth application, create the Authorization URL by setting the following properties:
     • InitiateOAuth: Set to OFF.
     • OAuthClientId: Set to the client Id assigned when you registered your application.
     • OAuthClientSecret: Set to the client secret assigned when you registered your application.
     Then call the GetOAuthAuthorizationURL stored procedure with the appropriate CallbackURL. Open the URL returned by the stored procedure in a browser.

2. Log in and grant permissions to the connector. You are then redirected to the callback URL, which contains the verifier code.
3. Save the value of the verifier code. Later you will set this in the OAuthVerifier connection property.

Next, you need to exchange the OAuth verifier code for OAuth refresh and access tokens. Set the following properties:

On the headless machine, set the following connection properties to obtain the OAuth authentication values:

• InitiateOAuth: Set this to REFRESH.
• OAuthVerifier: Set this to the verifier code.
• OAuthClientId: (custom applications only) Set this to the client Id in your custom OAuth application settings.
• OAuthClientSecret: (custom applications only) Set this to the client secret in the custom OAuth application settings.
• OAuthSettingsLocation: Set this to the location of the file where the driver saves the OAuth token values that persist across connections.

After the OAuth settings file is generated, you need to re-set the following properties to connect:

• InitiateOAuth: Set this to REFRESH.
• OAuthClientId: (custom applications only) Set this to the client Id assigned when you registered your application.
• OAuthClientSecret: (custom applications only) Set this to the client secret assigned when you registered your application.
• OAuthSettingsLocation: Set this to the location containing the encrypted OAuth authentication values. Make sure this location grants read and write permissions to the connector to enable the automatic refreshing of the access token.

Option 2: Transfer OAuth Settings

Prior to connecting on a headless machine, you need to create and install a connection with the driver on a device that supports an internet browser. Set the connection properties as described in "Desktop Applications" above.

After completing the instructions in "Desktop Applications", the resulting authentication values are encrypted and written to the location specified by OAuthSettingsLocation. The default filename is OAuthSettings.txt.

Once you have successfully tested the connection, copy the OAuth settings file to your headless machine.

On the headless machine, set the following connection properties to connect to data:

• InitiateOAuth: Set this to REFRESH.
• OAuthClientId: (custom applications only) Set this to the client Id assigned when you registered your application.
• OAuthClientSecret: (custom applications only) Set this to the client secret assigned when you registered your application.
• OAuthSettingsLocation: Set this to the location of your OAuth settings file. Make sure this location gives read and write permissions to the connector to enable the automatic refreshing of the access token.
