Question

尝试将以下代码的以下结果插入Postgres数据库的文本字段时，我收到以下错误代码：

TypeError：在字符串格式化期间并非所有参数都已转换

[ { “ id”：271， “ legacy_id”：43 “ country_id”：320， “ logo_path”：“ https://cdn.sportmonks.com/images/soccer/leagues/271.png”， “ name”：“ Superliga”， “ is_cup”：否， “ current_season_id”：12919， “ current_round_id”：167381， “ current_stage_id”：7088927， “ live_standings”：是的， “ coverage”：{ “ topscorer_goals”：是的， “ topscorer_assists”：是的， “ topscorer_cards”：是 } }， { “ id”：501， “ legacy_id”：66， “ country_id”：1161， “ logo_path”：“ https://cdn.sportmonks.com/images/soccer/leagues/501.png”， “ name”：“总理”， “ is_cup”：否， “ current_season_id”：12963， “ current_round_id”：null， “ current_stage_id”：null， “ live_standings”：是的， “ coverage”：{ “ topscorer_goals”：是的， “ topscorer_assists”：是的， “ topscorer_cards”：是 } }]

我尝试替换并编辑字典以删除'和'

data1 = json.load(response)

volume = (len(data1['data']))


data = (data1["data"])

jsonstr = (json.dumps(data, indent=4))

print(jsonstr)

connection = psycopg2.connect("host=localhost dbname=xxx user=xxx password=xxx")

cur = connection.cursor()

connection.autocommit = True

query =  "INSERT INTO xxx.xxx (xxx) VALUES (%s);"
sql = "INSERT INTO xxx.xxx VALUES (%s)"
cur.execute(sql, jsonstr)

我无法找出问题所在-可能很简单：）

Answer 1

最后找到了解决方案……您必须将一个元组传递给cur.execute，这样：

cur.execute(sql, (jsonstr,))有效
