使用Python从MySQL中的JSON对象插入多行

我试图将JSON对象中的多行添加到MySQL中，但只将最后一行添加到数据库中。有没有像“每行对应”这样的解决方案

JSON对象看起来像这样，一次可以保存5到50条记录

[{"one":"1.232.123","two":"test","three":1242,"four":"2,4","five":"test","six":"test","seven":"test"},{"one":"3.322.876","two":"test","three":1312,"four":"3,4","five":"test","six":"test","seven":"test"},{"one":"1.232.123","two":"test","three":1242,"four":"2,4","five":"test","six":"test","seven":"test"},{"one":"3.322.876","two":"test","three":1312,"four":"3,4","five":"test","six":"test","seven":"test"}]

您应该将

INSERT

语句放入

for

循环中：

for obj in json_obj:
    print(obj["one"])
    print(obj["two"])
    print(obj["three"])
    print(obj["four"])
    print(obj["five"])
    print(obj["six"])
    print(obj["seven"])

    cursor.execute("INSERT INTO test (one, two, three, four, five, six, seven) VALUES (%s,%s,%s,%s,%s,%s,%s)", (obj["one"], obj["two"], obj["three"], obj["four"], obj["five"], obj["six"], obj["seven"]))

cursor.execute中的缩进错误。 这是固定代码

import requests
import json
import pymysql
import urllib.request

con = pymysql.connect(host = 'host', port = 3306, user = 'user', passwd = 'pass', db = 'db')
cursor = con.cursor()
url = 'url to json'
urllib.request.urlopen(url).read()
response = urllib.request.urlopen(url).read()
json_obj = str(response, 'utf-8')
json_obj = json.loads(response.decode('utf-8'))

for obj in json_obj:
    print(obj["one"])
    print(obj["two"])
    print(obj["three"])
    print(obj["four"])
    print(obj["five"])
    print(obj["six"])
    print(obj["seven"])

    cursor.execute("INSERT INTO test (one, two, three, four, five, six, seven) VALUES (%s,%s,%s,%s,%s,%s,%s)", (obj["one"], obj["two"], obj["three"], obj["four"], obj["five"], obj["six"], obj["seven"]))

con.commit()
con.close()
