更快更强的 Python JSON 库。支持比如日期、numpy 数组等丰富的数据类型，而且速度更快 ```python >>> import orjson, datetime, numpy >>> data = { "type": "job", "created_at": datetime.datetime(1970, 1, 1), "status": "🆗", "payload": numpy.array([[1, 2], [3, 4]]), } >>> orjson.dumps(data, option=orjson.OPT_NAIVE_UTC | orjson.OPT_SERIALIZE_NUMPY) b'{"type":"job","created_at":"1970-01-01T00:00:00+00:00","status":"\xf0\x9f\x86\x97","payload":[[1,2],[3,4]]}' >>> orjson.loads(_) {'type': 'job', 'created_at': '1970-01-01T00:00:00+00:00', 'status': '🆗', 'payload': [[1, 2], [3, 4]]} ```
