接続の確立
コネクタ内で利用可能なオブジェクトは、"cdata.zohobooks" モジュールからアクセスできます。モジュールのオブジェクトを直接使用するには:
- モジュールを以下のようにインポートします。
import cdata.zohobooks as mod
- 接続を確立するには、以下のような適切な接続文字列を使用してコネクタオブジェクトからconnect() メソッドを呼び出します。
mod.connect("InitiateOAuth=GETANDREFRESH;OrganizationId=YourOrganizationId;")
Connecting to Zoho Books
You can refine the exact Zoho Books data retrieved using the following connection properties:
- OrganizationId (optional): The Id associated with the specific Zoho Books organization that you wish to connect to.
- If the value of Organization Id is not specified in the connection string, then the 本製品 automatically retrieves all available organizations and selects the first organization Id as the default.
- AccountsServer (optional): The full Account Server URL. Most of the time, the value of this property will be https://books.zoho.com, but if your account resides in a different location, then the domain should change accordingly (.eu, .in, .com.au, ...).
Authenticating to Zoho Books
Zoho Books uses the OAuth authentication standard. The 本製品 supports OAuth authentication for instances of the 本製品 running on your local machine, a web service, or on a headless machine.
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: 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 assigned when you registered your application.
- OAuthClientSecret (custom applications only): Set this to the client secret assigned when you registered your application.
- CallbackURL (custom application only): Set this to the redirect URI defined when you registered your application.
- The 本製品 obtains an access token from Zoho Books and uses it to request data.
- The OAuth values are saved in the path specified in OAuthSettingsLocation. These values persist across connections.
Web Applications
When connecting via a Web application, you need to register a custom OAuth application with Zoho Books. You can then use the 本製品 to get and manage the OAuth token values. See カスタムOAuth アプリの作成 for more information.
Get an OAuth Access Token
Set the following connection properties to obtain the OAuthAccessToken:
- OAuthClientId: Set this to the client Id in your application settings.
- OAuthClientSecret: Set this to the client secret in your application settings.
Then call stored procedures to complete the OAuth exchange:
- Call the GetOAuthAuthorizationURL stored procedure. Set the AuthMode input to WEB and the CallbackURL to the Redirect URI you specified in your application settings. The stored procedure returns the URL to the OAuth endpoint.
- Navigate to the URL that the stored procedure returned in Step 1. Log in and authorize the web application. You are redirected back to the callback URL.
- Call the GetOAuthAccessToken stored procedure. Set the AuthMode input to WEB. Set the Verifier input to the code parameter in the query string of the redirect URI. If necessary, set the Permissions parameter to request custom permissions.
To connect to data, set the OAuthAccessToken connection property to the access token returned by the stored procedure.
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.
- 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, as described in "Transfer OAuth Settings" below.
- 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.
- 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.
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 noted verifier code (the value of the code parameter in the redirect URI).
- 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 persist the encrypted OAuth authentication values to the specified file.
Test the connection to generate the OAuth settings file, then 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 file containing the encrypted OAuth authentication values. Make sure this file 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 path 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: 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 path to the OAuth settings file you copied from the machine with the browser. Make sure this file gives read and write permissions to the 本製品 to enable the automatic refreshing of the access token.
