我想打电话给我扑应用REST API。因此，其余的api post函数我保存在一个单独的文件中，该函数如下所示。
class process_raw_snowplow_event_data(luigi.Task):
dataset_date = luigi.DateParameter(default=date.today() - timedelta(days=1))
# force_run = luigi.BoolParameter()
_start = luigi.DateSecondParameter(default=datetime.utcnow())
file_root = luigi.Parameter()
def download_s3_file(self, s3_filename):
local_filename = "/Users/xxx/etl/%s" % s3_filename
s3_file_full_path =re.compile("snowplow-enrich-output/enriched/archive/run=" + self.dataset_date.strftime("%Y-%m-%d") +r"-\d{2}-\d{2}-\d{2}/*.")
try:
s3.download_file(Bucket=os.environ.get('SP_BUCKET'), Key=s3_file_full_path, Filename=local_filename)
except Exception as e:
logger.error("%s - Could not retrieve %s because: %s" % ("download_s3_file()", s3_filename, e))
raise
从我的调用函数中，我包装了URL以及每个不同api的标头和正文。我的函数调用示例如下。
