Getting Started

This page provides a guide to Establishing a Connection to WordPress in CData Cloud, as well as information on the available resources, and a reference to the available connection properties.

Connecting to WordPress

Establishing a Connection shows how to authenticate to WordPress and configure any necessary connection properties to create a database in CData Cloud

Accessing Data from CData Cloud Services

Accessing data from WordPress through the available standard services and CData Cloud administration is documented in further details in the CData Cloud Documentation.

Establishing a Connection

Connect to WordPress by selecting the corresponding icon in the Database tab. Required properties are listed under Settings. The Advanced tab lists connection properties that are not typically required.

Connecting to WordPress

At this time, CData Cloud only supports connecting to self-hosted WordPress instances. To connect to data, supply the Url to your wordpress site, and then authenticate as described below.

Supply the URL in its full form. For example, if your site is hosted at http://localhost/wp/wordpress', the URL should be http://localhost/wp/wordpress, and not 'htpp://localhost'. Failure to supply the URL in its full form results in a 'site not found' error.

WordPress supports two types of authentication:

Basic authentication, which is recommended for use in a testing environment; and
OAuth 2.0 authentication, which supports browser-based access from a Desktop application, Web application, or Headless Machine.

Basic Authentication

Basic authentication is recommended for testing environments only.

Before you configure WordPress to use Basic Authentication:

Ensure that your WordPress login has adminstrative privileges.
Know what version of WordPress is running at the local host. (WordPress 4.7 and later support the WordPress REST API natively; earlier versions require the use of a Basic Authentication plug-in to secure access to the REST API.)

To configure Basic Authentication:

Log into your WordPress host.
If you are running an earlier WordPress version than 4.7, install the REST API plugin.
Install the Basic Authentication plugin.
To create custom taxonomies, install the Simple Taxonomy Refreshed
If you prefer installing the plugins manually, extract the compressed folders to the wp-content\plugins folder and then enable the plugins via the WordPress admin interface.
Set the following connection properties:
- AuthScheme: Basic.
- Url: Your WordPress URL.
- User: Your username.
- Password: Your password.

You are now ready to connect.

OAuth 2.0 Authentication

For all non-testing environments, WordPress supports OAuth authentication only. To enable this authentication from all OAuth flows, you must set AuthScheme to OAuth, and you must create a custom OAuth application.

The following subsections describe how to authenticate to WordPress from three common authentication flows. For information about how to create a custom OAuth application, see Creating a Custom OAuth Application. For a complete list of connection string properties available in WordPress, see Connection.

Automatic refresh of the OAuth access token:

To have the Cloud automatically refresh the OAuth access token, do the following:

Before connecting to data for the first time, set the following connection parameters:
- InitiateOAuth: REFRESH.
- OAuthClientId: The client Id in your application settings.
- OAuthClientSecret: The client secret in your application settings.
- OAuthAccessToken: The access token returned by GetOAuthAccessToken.
- OAuthSettingsLocation: The path where you want the Cloud to save the OAuth values, which persist across connections.
On subsequent data connections, set the following:
- InitiateOAuth
- OAuthSettingsLocation

Advanced Settings

Customizing the SSL Configuration

By default, the Cloud attempts to negotiate SSL/TLS by checking the server's certificate against the system's trusted certificate store. To specify another certificate, see the SSLServerCert property for the available formats to do so.

Connecting Through a Firewall or Proxy

HTTP Proxies

To connect through the Windows system proxy, you do not need to set any additional connection properties. To connect to other proxies, set ProxyAutoDetect to false.

In addition, to authenticate to an HTTP proxy, set ProxyAuthScheme, ProxyUser, and ProxyPassword, in addition to ProxyServer and ProxyPort.

Other Proxies

Set the following properties:

To use a proxy-based firewall, set FirewallType, FirewallServer, and FirewallPort.
To tunnel the connection, set FirewallType to TUNNEL.
To authenticate, specify FirewallUser and FirewallPassword.
To authenticate to a SOCKS proxy, additionally set FirewallType to SOCKS5.

Data Model

The CData Cloud models entities in the WordPress API as tables, views, and stored procedures. These are defined in schema files, which are configuration files that you can customize with a text editor.

Stored Procedures

Stored Procedures are function-like interfaces to the data source. They can be used to search, update, and modify information in the data source.

Using Query Processing

The Cloud offloads as much of the SELECT statement processing as possible to the WordPress APIs and then processes the rest of the query within the Cloud. The following sections document API limitations and requirements.

Tables

The Cloud models the data in WordPress as a list of tables in a relational database that can be queried using standard SQL statements.

CData Cloud - WordPress Tables


Name	Description
Categories	Create, update, delete, and query Categories to use for categorizing your posts.
Comments	Create, update, delete, and query Comments associated with a post.

The Cloud uses the WordPress API to process supported filters. The Cloud processes other filters client-side within the Cloud. You can turn off the client-side execution of the query by setting SupportEnhancedSQL to false in which case any search criteria that refers to other columns will cause inconsistent data. For example, the following queries are processed server side.

SELECT * FROM Comments WHERE Id = 61
SELECT * FROM Comments WHERE Id IN (61, 45)
