Web Services

Request

CORS

The Axelor Open Platform provides REST like JSON web services.

The web services are accessible /ws/ endpoint, for example:

http://localhost:8080/open-platform-demo/ws/

Every web service returns JSON data in a specific format. Also, some web services requires JSON data as request body.

Request

{
  "model"   : "",  (1)
  "offset"  : 0,   (2)
  "limit"   : 40,  (3)
  "sortBy"  : [],  (4)
  "data"    : {},  (5)
  "records" : [],  (6)
  "fields"  : []   (7)
}

1	`model` - resource model name
2	`offset` - pagination offset
3	`limit` - pagination limit
4	`sortBy` - list of fields to sort the result
5	`data` - json map, varies on web service
6	`records` - list of json maps or record ids
7	`fields` - name of the fields

These request attributes are service dependent, only the required attributes have to be provided.

Response

{
  "status"  : 0,    (1)
  "offset"  : 0,    (2)
  "total"   : 0,    (3)
  "errors"  : {},   (4)
  "data"    : {},   (5)
  "data"    : []    (5)
}

1	`status` - response status
2	`offset` - current pagination offset
3	`total` - total number of records matched
4	`errors` - validation errors (key is field name, value is error message)
5	`data` - json map or array depending on the service type

The response attributes are service dependent, only the specific attributes may be returned by the service.

The status attribute can have following values:

Code	Reason
0	success
-1	failure
-4	validation error

CORS

The Axelor Open Platform supports CORS, generally required for calling web services from mobile applications.

It can be controlled with following settings:

# CORS configuration
# ~~~~~
# CORS settings to allow cross origin requests

# regular expression to test allowed origin or * to allow all (not recommended)
#cors.allow.origin = *
#cors.allow.credentials = true
#cors.allow.methods = GET,PUT,POST,DELETE,HEAD,OPTIONS
#cors.allow.headers = Origin,Accept,X-Requested-With,Content-Type,Access-Control-Request-Method,Access-Control-Request-Headers
#cors.expose.headers =
#cors.max.age = 1728000

Generally, you should only set cors.allow.origin to a list of domains to allow. Other options should be left as it is.

To avoid preflight cors requests, do not add X-Requested-With header and provide Accept: application/json header for GET and POST requests and use Content-Type: text/plain;json header for POST methods.
