示例1: cb
metadata: (req, file, cb) => cb(new Error(), null),
logLevel: 'all',
root: (req, file, cb) => cb(null, 'unicorns')
});
let urlCtr = new MulterGridfsStorage({
url: '',
filename: (req, file, cb) => cb(null, ''),
chunkSize: (req, file, cb) => cb(null, 1),
identifier: (req, file, cb) => cb(null, ''),
metadata: (req, file, cb) => cb(new Error(), {}),
logLevel: 'all',
root: (req, file, cb) => cb(null, '')
});
// Other properties are optional
let gfsOnly = new MulterGridfsStorage({
gfs: new Grid()
});
let urlOnly = new MulterGridfsStorage({
url: ''
});
function noop() {
}
// Extends event emitter
gfsCtr.on('connection', noop);
urlCtr.addListener('conection', noop);
gfsOnly.removeAllListeners('conection');
示例2: MulterGridfsStorage
connectionOpts: {},
file: (req, file) => {
return {
metadata: file.mimetype
};
}
};
// All options
const dbFileStorage = new MulterGridfsStorage(opt1);
const urlFileStorage = new MulterGridfsStorage(opt2);
// Other properties are optional
const promiseStorage = new MulterGridfsStorage({
db: dbPromise
});
const dbStorage = new MulterGridfsStorage({
db
});
const urlStorage = new MulterGridfsStorage({
url: 'mongodb://yourhost:27017/database'
});
// Extends event emitter
promiseStorage.on('connection', () => {});
