Chapter 53. Box Component

Available as of Camel version 2.14

The Box component provides access to all of the Box.com APIs accessible using https://github.com/box/box-java-sdk. It allows producing messages to upload and download files, create, edit, and manage folders, etc. It also supports APIs that allow polling for updates to user accounts and even changes to enterprise accounts, etc.

Box.com requires the use of OAuth2.0 for all client application authentication. In order to use camel-box with your account, you’ll need to create a new application within Box.com at https://developer.box.com. The Box application’s client id and secret will allow access to Box APIs which require a current user. A user access token is generated and managed by the API for an end user.

Maven users will need to add the following dependency to their pom.xml for this component:

<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-box</artifactId>
    <version>${camel-version}</version>
</dependency>

53.1. Connection Authentication Types

The Box component supports three different types of authenticated connections.

53.1.1. Standard Authentication

Standard Authentication uses the OAuth 2.0 three-legged authentication process to authenticate its connections with Box.com. This type of authentication enables Box managed users and external users to access, edit, and save their Box content through the Box component.

53.1.2. App Enterprise Authentication

App Enterprise Authentication uses the OAuth 2.0 with JSON Web Tokens (JWT) to authenticate its connections as a Service Account for a Box Application. This type of authentication enables a service account to access, edit, and save the Box content of its Box Application through the Box component.

53.1.3. App User Authentication

App User Authentication uses the OAuth 2.0 with JSON Web Tokens (JWT) to authenticate its connections as an App User for a Box Application. This type of authentication enables app users to access, edit, and save their Box content in its Box Application through the Box component.

53.2. Box Options

The Box component supports 2 options, which are listed below.

Name	Description	Default	Type
configuration (common)	To use the shared configuration		BoxConfiguration
resolveProperty Placeholders (advanced)	Whether the component should resolve property placeholders on itself when starting. Only properties which are of String type can use property placeholders.	true	boolean

The Box endpoint is configured using URI syntax:

box:apiName/methodName

with the following path and query parameters:

53.2.1. Path Parameters (2 parameters):

Name	Description	Default	Type
apiName	Required What kind of operation to perform		BoxApiName

exceptionHandler (consumer)	To let the consumer use a custom ExceptionHandler. Notice if the option bridgeErrorHandler is enabled then this option is not in use. By default the consumer will deal with exceptions, that will be logged at WARN or ERROR level and ignored.		ExceptionHandler
exchangePattern (consumer)	Sets the exchange pattern when the consumer creates an exchange.		ExchangePattern
httpParams (advanced)	Custom HTTP params for settings like proxy host		Map
synchronous (advanced)	Sets whether synchronous processing should be strictly used, or Camel is allowed to use asynchronous processing (if supported).	false	boolean
accessTokenCache (security)	Custom Access Token Cache for storing and retrieving access tokens.		IAccessTokenCache

53.4. URI format

box:apiName/methodName

apiName can be one of:

collaborations
comments
event-logs
files
folders
groups
events
search
tasks
users

53.5. Producer Endpoints:

Producer endpoints can use endpoint prefixes followed by endpoint names and associated options described next. A shorthand alias can be used for some endpoints. The endpoint URI MUST contain a prefix.

Endpoint options that are not mandatory are denoted by []. When there are no mandatory options for an endpoint, one of the set of [] options MUST be provided. Producer endpoints can also use a special option inBody that in turn should contain the name of the endpoint option whose value will be contained in the Camel Exchange In message.

Any of the endpoint options can be provided in either the endpoint URI, or dynamically in a message header. The message header name must be of the format CamelBox.<option>. Note that the inBody option overrides message header, i.e. the endpoint option inBody=option would override a CamelBox.option header.

If a value is not provided for the option defaultRequest either in the endpoint URI or in a message header, it will be assumed to be null. Note that the null value will only be used if other options do not satisfy matching endpoints.

In case of Box API errors the endpoint will throw a RuntimeCamelException with a com.box.sdk.BoxAPIException derived exception cause.

For authentication with Box, set the authentication properties on the component as demonstrated in the following example:

BoxConfiguration configuration = new BoxConfiguration();
configuration.setClientId("clientId");
configuration.setClientSecret("clientSecret");
configuration.setUserName("userName");
configuration.setUserPassword("userPassword");

// add BoxComponent to Camel context
BoxComponent component = new BoxComponent(context);
component.setConfiguration(configuration);
context.addComponent("box", component);

53.10. Samples

The following route uploads new files to the user’s root folder:

from("file:...")
    .to("box://files/upload/inBody=fileUploadRequest");

The following route polls user’s account for updates:

from("box://events/listen?startingPosition=-1")
    .to("bean:blah");

The following route uses a producer with dynamic header options. The fileId property has the Box file id and the output property has the output stream of the file contents, so they are assigned to the CamelBox.fileId header and CamelBox.output header respectively as follows:

from("direct:foo")
    .setHeader("CamelBox.fileId", header("fileId"))
    .setHeader("CamelBox.output", header("output"))
    .to("box://files/download")
    .to("file://...");
