Question

我有以下代码

client = bigquery.Client()
dataset_id = 'dataset'  # replace with your dataset ID
table_id = 'table'  # replace with your table ID
table_ref = client.dataset(dataset_id).table(table_id)
table = client.get_table(table_ref)  # API request
rows_to_insert = []
bq = bigquery.Client(project='project-id')
query = """SELECT Url FROM `project-id.dataset.urltable`"""
query_job = bq.query(query)
data = query_job.result()
rows = list(data)


def main():
    for row in rows:
        URL = urllib.request.urlopen(row[0])
        soup_page = soup(URL, features="lxml")
        try:
            data = json.loads(soup_page.find_all('script', type='application/ld+json')[1].text)
        except:
            data ='unknown'
        try:
            price_ruw = data['offers']['price']
            shopprice = price_ruw.replace(',','.')
        except: 
            price = 0
        try:
            ean = data['gtin13']
            ean = str(ean)
        except:
            ean = 'unknown'
        try:
            title_ruw1 = data['name']
            title_ruw = title_ruw1
            tile_trim = title_ruw[:750]
            title = tile_trim.replace("'", "")
        except:
            title = "unknown"            
        try:
            reviews = data['aggregateRating']['reviewCount']
        except:
            reviews = 0
        try:
            score =  (float(data['aggregateRating']['ratingValue']) * 2)
        except:
            score = 0
        datenow = (datetime.datetime.now())
        shoplink = row[0]
        rows_to_insert.append([shoplink,ean,title,reviews,score,shopprice,datenow])
    client.insert_rows(table, rows_to_insert)  # API request
main()

在Google Cloud平台上测试此代码即可

Error: function crashed. Details:
main() takes 0 positional arguments but 2 were given

但是，部署此代码时不会出现错误。仅安排此查询无效，因为它始终显示以下错误。

对于部署，我使用以下命令（有效）

gcloud functions deploy <function> --entry-point main --
runtime python37 --trigger-resource <name> --trigger-event google.pubsub.topic.publish --timeout 540s

尚不清楚如何触发此函数，但它看起来像是“背景函数”，这意味着即使未使用它们也需要采用两个参数：

def main(data, context):
   ...

有关更多信息，请参见https://cloud.google.com/functions/docs/concepts/events-triggers。

main（）接受0个位置参数，但给出了2个
