接続の確立

CData Cmdlets ユーザーは、データモジュールをインストールし、接続プロパティを設定してスクリプトを開始できます。このセクションでは、CSV インポートおよびエクスポートcmdlet などのネイティブPowerShell cmdlet でAsana Cmdlets を使用する例を示します。

インストールおよび接続

PSGet がある場合は、PowerShell Gallery から次のコマンドを使ってcmdlet をインストールできます。CData サイトからセットアップを取得することもできます。

Install-Module AsanaCmdlets

プロファイルに以下を追加すると、次のセッションでcmdlet がロードされます。

Import-Module AsanaCmdlets;

Connect-Asana cmdlet を使って、別のcmdlet に渡すことができる接続オブジェクトを作成します。

$conn = Connect-Asana -InitiateoAuth "GETANDREFRESH" -OAuthClientId "YourClientId" -OAuthClientSecret "YourClientSecret" -CallbackURL "http://localhost:33333"

Connecting to Asana

You can optionally set the following to refine the data returned from Asana.

WorkspaceId: The globally unique identifier (gid) associated with your Asana Workspace to only return projects from the specified Workspace. To get your Workspace Id, navigate to https://app.asana.com/api/1.0/workspaces while logged into Asana. This displays a JSON object containing your Workspace name and Id.
ProjectId: The globally unique identifier (gid) associated with your Asana Project to only return data mapped under the specified Project. Project Ids can be found in the URL of your project's Overview page. This will be the numbers directly after /0/.

Authenticating to Asana

Asana uses the OAuth authentication standard.

User Accounts (OAuth)

AuthScheme must be set to OAuth in all user account flows.

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 アプリの作成 for information about creating custom applications and reasons for doing so.

Get and Refresh the OAuth Access Token

After setting the following, you are ready to connect:

InitiateOAuth: GETANDREFRESH. You can use InitiateOAuth to avoid repeating the OAuth exchange and manually setting the OAuthAccessToken.
OAuthClientId (custom applications only): The client Id assigned when you registered your app.
OAuthClientSecret (custom applications only): The client secret assigned when you registered your app.
CallbackURL (custom application only): The redirect URI defined when you registered your app. For example: https://localhost:3333

When you connect, the 本製品 opens Asana's OAuth endpoint in your default browser. Log in and grant permissions to the application. The 本製品 then completes the OAuth process:

The 本製品 obtains an access token from Asana and uses it to request data.
The OAuth values are saved in the location specified in OAuthSettingsLocation, to be persisted across connections.

The 本製品 refreshes the access token automatically when it expires.

Headless Machines

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

Choose one of two options:
- Option 1: Obtain the OAuthVerifier value as described in "Obtain and Exchange a Verifier Code" below.
- Option 2: Install the 本製品 on a machine with an internet browser and transfer the OAuth authentication values after you authenticate through the usual browser-based flow.
Then configure the 本製品 to automatically refresh the access token on 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.

Choose one of these options:
- If you are using the Embedded OAuth Application, call the GetOAuthAuthorizationURL stored procedure. Open the URL returned by the stored procedure in a browser.
- If you are using a custom OAuth application, set 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.
Log in and grant permissions to the 本製品. You are then redirected to the redirect URI. There will be a parameter called code appended to the redirect URI. Note the value of this parameter. 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.

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

InitiateOAuth: REFRESH.
OAuthVerifier: The noted verifier code (the value of the code parameter in the redirect URI).
OAuthClientId (custom applications only): The client Id assigned when you registered your application.
OAuthClientSecret (custom applications only): The client secret assigned when you registered your application.
OAuthSettingsLocation: The location where the encrypted OAuth authentication values are saved and persist.

Test the connection to generate the OAuth settings file, then re-set the following properties to connect:

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

Option 2: Transfer OAuth Settings

Prior to connecting on a headless machine, you need to install and create 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.

Test the connection to generate the OAuth settings file, then copy the OAuth settings file to your headless machine.

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

InitiateOAuth: REFRESH.
OAuthClientId (custom applications only): The client Id assigned when you registered your application.
OAuthClientSecret (custom applications only): The client secret assigned when you registered your application.
OAuthSettingsLocation: The location of the OAuth settings file you copied from the machine with the browser. Make sure this location gives read and write permissions to the 本製品 to enable the automatic refreshing of the access token.

Service Accounts

To authenticate with a Server Account (Enterprise only), use a Personal Access Token by setting these connection properties:

InitiateOAuth: OFF.
OAuthAccessToken: Your access token value.

For more more information, see the Asana documentation for personal access tokens and service accounts.

データの取得

Select-Asana cmdlet はデータを取得するためのネイティブなPowerShell インターフェースを提供します。

$results = Select-Asana -Connection $conn -Table "projects" -Columns @("Id, WorkspaceId") -Where "Archived='true'"

Invoke-Asana cmdlet はSQL インターフェースを提供します。このcmdlet を使うと、Query パラメータを介してSQL クエリを実行できます。

cmdlet 出力のパイプ処理

cmdlet は行オブジェクトをパイプラインに一度に一行ずつ返します。以下は、結果をCSV ファイルにエクスポートします。

Select-Asana -Connection $conn -Table projects -Where "Archived = 'true'" | Select -Property * -ExcludeProperty Connection,Table,Columns | Export-Csv -Path c:\myprojectsData.csv -NoTypeInformation

Select-Asana からの結果をSelect-Object cmdlet にパイプして、Export-CSV cmdlet にパイプする前にいくつかのプロパティを実行していることがわかるでしょう。これをする理由は、CData Cmdlets は接続、テーブル、およびカラムの情報を結果セットの各行オブジェクトに追加しますが、必ずしもその情報がCSV ファイルに必要ではないからです。

ただし、これによってcmdlet の出力を別のcmdlet にパイプすることが容易になります。以下に、結果セットをJSON に変換する例を示します。

 
PS C:\> $conn  = Connect-Asana -InitiateoAuth "GETANDREFRESH" -OAuthClientId "YourClientId" -OAuthClientSecret "YourClientSecret" -CallbackURL "http://localhost:33333"
PS C:\> $row = Select-Asana -Connection $conn -Table "projects" -Columns (Id, WorkspaceId) -Where "Archived = 'true'" | select -first 1
PS C:\> $row | ConvertTo-Json
{
  "Connection":  {

  },
  "Table":  "projects",
  "Columns":  [

  ],
  "Id":  "MyId",
  "WorkspaceId":  "MyWorkspaceId"
}

データの削除

以下は、抽出条件に合うあらゆるレコードを削除します。

Select-Asana -Connection $conn -Table projects -Where "Archived = 'true'" | Remove-Asana

データの変更

cmdlet はデータクレンジング同様、データの変換を容易にします。次の例は、レコードがすでに存在するかどうか、挿入する前に更新が必要かどうかをチェックしてから、CSV ファイルのデータをAsana にロードします。

Import-Csv -Path C:\MyprojectsUpdates.csv | %{
  $record = Select-Asana -Connection $conn -Table projects -Where ("Id = `'"+$_.Id+"`'")
  if($record){
    Update-Asana -Connection $conn -Table projects -Columns @("Id","WorkspaceId") -Values @($_.Id, $_.WorkspaceId) -Where "Id  = `'$_.Id`'"
  }else{
    Add-Asana -Connection $conn -Table projects -Columns @("Id","WorkspaceId") -Values @($_.Id, $_.WorkspaceId)
  }
}
