Analysis REST API Contracts

• _Implementation available on contrib/webhob-poky/master-next_

This page gives you information on the Toaster API and its search operation URI, parameters, and responses. You might also be interested in the [[Web Hob#Installation and Running|Toaster installation and running instructions].

WebHob is accessible through REST APIs, which make the backend available to any client. The data collected during the build is available on no-restrictions, anonymous, read-only API running on the local host machine.

General

The data interface is available as a search query returning a list of typed objects. The request method must be GET. The answers are always returned as JSON.

API version

The REST API is versioned as to allow further upgrades without having to maintain backward compatibility through changing the major version number. Minor version numbers are inteded to signify a capability level while maintaining compatibility.

This is the API version 1.0. All API requests are grouped under URL:

GET /api/1.0/

Object types

The API can return Build, Task, Package, Layer, Layerversion, Recipe, Variable, Recipe Dependencies, Package Dependencies, Configuration Variables and Log Messages. Each object is described below.

Search operation

The primary operation of the API is to retrieve a set of objects from the backend based on a search operation. The result will also contain all the data for the objects being returned, as to avoid separate connections to further bring the objects of the type queried.

The search operation can also specify the ordering of the results by key.

The search parameters are the same for all object types.

URI

All the search endpoints follow the same URI pattern

GET /api/1.0/{on}s/?{parameters}

• The on is the object name, one the endpoints described below.
• The parameters are described in the next section, and are the same for all search queries

Parameters

Name	Type	Description	Comments
limit	number	The number of objects to be returned	-
offset	number	Offset into the search result index.	-
search	string	Search string for all fields	The argument is the string to searched in the database. The backend MUST return only records that match the string.
filter	string	String used to specify result filter function	The general form: "<FIELD>:<VALUE>[,<FIELD>:<VALUE>]*". The backend MUST only return records that have FIELD matching to the VALUE specified. The <FIELD> names for each object type are the property names of the object.
orderby	string	the name of the field that determens the sorting of the resuls.	"<FIELD>:<ORDER_DIRECTION>". The results are ordered by the <FIELD> values in the <ORDER_DIRECTION> order. <ORDER_DIRECTION> values may be "asc" or "desc".

Response

All the responses are in JSON format. The response contains a set of fields describing the content of the data, and an array with the object data inside it.

Build

Returns information about the builds recorded by Webhob.
