NBI API Description
Introduction
OSM North Bound Interface is a REST-full following ETSI SOL005 standard. It admits both YAML/JSON formats.
By default it serves https (auto-signed certificate) on port 9999. Bearer authentication (with token) is used. Basic authentication or no authentication is also possible changing 'nbi.cfg' file.
For developping porpouses it admits web browser navigation using a basic http format.
Request headers
Accept: 'application/json','application/yaml' in most of the cases. Use 'text/html' for web navigation. Use 'text/plain','application/zip' for descriptor artifacts showing. This header field shall be present if the response is expected to have a non-empty message body.
Content-Type: 'application/json','application/yaml' for most of the cases. For packages uploading use 'application/gzip','application/zip','application/x-gzip','application/binary'. For descriptor artifacts it can be used 'text/plain'. This header field shall be present if the request has a non-empty message body.
Authorization: 'Bearer <token_id>'. The authorization token for the request. It is mandatory except when a token is requested.
Content-Range: '<first byte>-<last byte>0/<total>'. It allows uploading a descriptor by chunks.
Content-File-MD5: '<md5>'. MD5 of uploaded package.
Content-Filename: '<filename>'. Filename of the uploaded package.
Query-String-Format: '<yaml>'. Parses query string values using yaml format.
Response headers
Content-Type: 'application/json','application/yaml' is the more normal. 'text/html' when web navigation. 'application/gzip','text/plain' for descriptor artifacts
Location: '/<main_topic>/v1/<topic>/<id>'. Always that something is created, this header is present containing URL to this element.
WWW-Authenticate: 'Bearer realm="{}"'. When Authentication error is obtained.
Retry-After: '
Query string
Query string has the format: '?key=value&key2=value2&...'.
Some special keys are:
- FORMAT=True Forces and operation. It disables descriptor checkings, dependency cheking. For delete, it allows deleting things that cannot done in normal operation because dependency. But beware that forcing deletion will not deletes created things at VIM level.
For GET method it allows filtering with this format, follows SOL005 section 4.3.2:
query string := ?<simpleFilterExpr>["&"<simpleFilterExpr>]* simpleFilterExpr := <attrName>["."<attrName>]*["."<op>]"="<value>[","<value>]* op := "eq" | "neq" (or "ne") | "gt" | "lt" | "gte" | "lte" | "cont" | "ncont" equal (by default), not equal, greater than, less than, greater than or equal, less than or equal, contains, not contains attrName := string. For filtering inside array, use the index element of the array, or add ANYINDEX to apply the filtering over the same array element
For PUT/POST/PATCH It allows override e.g. package content, with the values of this query string
