Configuring OAuth for custom gadgets

The HCL Connections™ supports an OAuth 2.0 consumer proxy that allows the Homepage component to surface gadgets in an OpenSocial container that can interact with an OAuth 2.0 protected service. In order for this proxy to function, there are a series of new administration commands that are exposed in the News service to define OAuth 2.0 providers, clients, and the associated gadget that will interact with the protected service.

Commands for configuring custom gadgets

See the topic Running administrative commands for steps on executing newsAdmin.py before running OAuth proxy configuration commands in HCL Connections.

Perform any of the following tasks using the appropriate command:

Counting providers

NewsOAuth2ConsumerService.countProvider() : Returns the total number of OAuth 2.0 providers registered with the consumer proxy. There are no parameters.

Example:

```
wsadmin>NewsOAuth2ConsumerService.countProvider()

20
```

Returning a list of providers

NewsOAuth2ConsumerService.browseProvider(int pageSize, int pageNumber) : Returns a list of Map objects that represent each OAuth 2.0 provider registered with the consumer proxy, in ascending ordered by provider name. The following information is returned for each map object in the returned list:

-   authHeader: "true" or "false"
-   authUrl: the authentication url endpoint for the provider
-   clientAuth: the client authentication method in use
-   name: the name of the provider
-   tokenUrl: the token url endpoint for the provider
-   urlParam: "true" or "false"

pageSize
:   The maximum number of providers to list per page. The default value is 20. This parameter is optional.

pageNumber
:   The number of the page to display. For example, if you specify in the pageSize parameter that each page will have 50 items, page 1 will contain items 1-50. The default value is 1. This parameter is optional.

Example:

```
wsadmin>NewsOAuth2ConsumerService.browseProvider(50, 1)

```

Returning a single provider

NewsOAuth2ConsumerService.findProvider(string providerName) : Returns a Map with information about the registered OAuth 2.0 provider with the specified name.

providerName
:   The unique provider name.

Example:

```
wsadmin>NewsOAuth2ConsumerService.findProvider("provider123")
