我无法处理JSON文件中返回的引号内的引号。 Python做一件事来处理它而postgredb做另一件事。 我对如何处理它感到困惑。
说实话，我从google API获得了一个json：

现在的问题是，我想让它直接进入我的POSTGREDB的JSON格式列。 POSTGREDB非常适合处理JSON。
我尝试做的是逃避此API中的单引号...
但这意味着POSTGREDB会弹出错误。
我生气了。我尝试了以下方法：URL='https://maps.googleapis.com/maps/api/place/details/json?placeid='+rows[0]+'&key=Something something'
file = urllib.request.urlopen(URL)
file1=file.read()
file2=json.loads(file1)
file3=json.dumps(file2)
query='update public.attraction set g_json_1=\'%s\' where google_place_id="%s"'% (file3,str(rows[0]))
print(query)
cursor.execute(query)
答案 0 :(得分：0)
我认为在Postgres中，你可以通过加倍'
''
因此，您可能需要在json内容中将'替换为''
URL='https://maps.googleapis.com/maps/api/place/details/json?placeid='+rows[0]+'&key=Something something'
file = urllib.request.urlopen(URL)
file1=file.read()
file2=json.loads(file1)
file3=json.dumps(file2)
file3 = file3.replace("'", "''") # escape single quotes
query='update public.attraction set g_json_1=\'%s\' where google_place_id="%s"'% (file3,str(rows[0]))
print(query)
cursor.execute(query)
我希望它有所帮助
