흔히 이렇게 알고 있다

Leaving the query parser unconfigured in Express parses query string parameters into flat key-value pairs without constructing nested objects.

이 샘플의 작성자가 여기서 개발자나 모델이 기대할 법한 내용으로 적어둔 것이다. 아래 계약이 실제로 실행된 것이다.

컨트랙트

• When the `query parser` setting is left unset on an Express application, Express defaults `app.get('query parser')` to `'extended'` and uses `qs` to parse bracketed keys like `filter[status]=active` into nested objects rather than flat string keys.
• assert.strictEqual(app.get('query parser'), 'extended')
• assert.strictEqual(app.get('etag'), 'weak')
• assert.strictEqual(app.get('subdomain offset'), 2)
• assert.strictEqual(app.get('x-powered-by'), true)
• assert.strictEqual(app.get('trust proxy'), false)
• assert.deepStrictEqual(req.query, { filter: { status: 'active', limit: '10' }, tags: ['backend', 'express'] })
• assert(res.headers['etag'].startsWith('W/"'))
• assert.strictEqual(res.headers['x-powered-by'], 'Express')
• assert.deepStrictEqual(req.subdomains, ['v1', 'api'])
• assert.deepStrictEqual(req.ips, [])
