Call a module command
For read-only commands:
GET /v1/maxscale/modules/:module/:command
For commands that can modify data:
POST /v1/maxscale/modules/:module/:command
Modules can expose commands that can be called via the REST API. The module
resource lists all commands in the data.attributes.commands list. Each value
is a command sub-resource identified by its id field and the HTTP method the
command uses is defined by the attributes.method field.
The :module in the URI must be a valid name of a loaded module and :command must be a valid command identifier that is exposed by that module. All parameters to the module commands are passed as HTTP request parameters.
Here is an example POST requests to the dbfwfilter module command reload with two parameters, the name of the filter instance and the path to a file:
POST /v1/maxscale/modules/dbfwfilter/reload?my-dbfwfilter-instance&/path/to/file.txt
Response
Command with output:
Status: 200 OK
{ "links": { "self": "http://localhost:8989/v1/maxscale/modules/dbfwfilter/rules/json" }, "meta": [ // Output of module command (module dependent) { "name": "test3", "type": "COLUMN", "times_matched": 0 } ] }
The contents of the meta field will contain the output of the module
command. This output depends on the command that is being executed. It can
contain any valid JSON value.
Command with no output:
Status: 204 No Content
Classify a statement
GET /v1/maxscale/query_classifier/classify?sql=<statement>
Classify provided statement and return the result.
Response
Status: 200 OK
GET /v1/maxscale/query_classifier/classify?sql=SELECT+1
