4. `http_api` — HTTP-API¶

This document describes how to communicate with an OpenPLM server to build a plugin.

4.1. How to make a query¶

You just have to make a POST or GET request to the server. All valid urls are described above.

Warning

You must set the user-agent to ‘openplm’, this is to prevent a CSRF attack. If an user click on a link related to the api, he will receive a 403 forbidden response. Moreover, a XMLHttpRequest object can not set the user agent if the script was launched from another domain.

4.2. Returned value¶

Results are returned in a JSON format. Each result contains at least two fields:

api_version

the api version (current : 1.1)

result

"ok" if no error occurred (i.e. the query was valid and succeed)

"error" if an error occurred

For example, a minimal result would be:

{"result": "ok", "api_version": "1.1"}

If an error occurred, an extra field is add:

error

a short description of the error

For example, a result could be:

{"result": "error", "api_version": "1.1", "error": "Oups an error occured"}

4.3. Authentication¶

Several queries require an authenticated user.

The authentication is based on Django module auth, so you need to make query with a cookies support.

To authenticated, see login().

4.4. Object fields¶

Some queries return a field which describes an object.

The fields are:

Field Description

id id of the object

type type of the object

reference reference of the object

revision revision of the object

name name of the object

4.5. Query fields¶

Some queries return a description of an object field, this description contains the following fields:

Field Description

name name of the field. Examples: "type", "reference", "wheels"

label verbose name more comprehensible for an user. Example: "Number of wheels"

type type of the field, the avalaible types are described above

initial initial (default) value for the field, may be None.

others fields see above

4.5.1. Available types¶

The available types are:

Type Description

"int" an integer (positive or negative)

"float" a float (positive or negative)

"decimal" a number with a restrictive format

"boolean" a boolean (True or False)

"text" a string

"choice" a type to choose among several values

If the type is "choice", another field, called "choices" is given. It contains a list of tuple (short_value, long_value) where short_value is the value for the server and long_value is the value for the user.

4.5.2. Optional fields¶

Some other fields may be given:

Field Associated types Description

min_value "int", "float", "decimale minimal value accepted by the field

max_value "int", "float", "decimale maximal value accepted by the field

min_length "text", minimal length of the field

max_length "text", maximal length of the field

4.6. File fields¶

Some queries return information about a file.

The fields are:

Field Description

id id of the file

filename name of the file (with its extension)

size size of the file in bytes
