Given a configured query which returns an array of fileUri's fetchThe associated Files to package them in a zip.
The files are stored according to the model mu-file-service The service is based on mu-javascript-template.
Query is configured in a javascript file. It should comply to the following structure. (This is more an example then a spec. The picture is clear right?)
import { querySudo as query } from '@lblod/mu-auth-sudo';
import { uuid } from 'mu';
const fileQuery = async function( jobsParamsProvidedAsJsonPostBody ){
//Get some files valid for your system. You can do any query.
let result = await query(`
SELECT ?file ?filename WHERE {
//Make sure you have ?file and ?fileName
}
`);
return {files: result.results.bindings || [], packageName: `${new Date().toISOString()}_${uuid()}.zip`};
};
export default fileQuery;
curl -d '{"whatever":"json", "data":"you need"}' -H "Content-Type: application/json" -X POST http://localhost/simple-file-package-jobs
This will create a job that will be picked up in an asynchronous way.
If you want to trigger the packaging pipeline manually.
curl -H "Content-Type: application/json" -X POST http://localhost/simple-file-package-pipeline
Defaults of the options are provided.
