Я пытаюсь добавить несколько строк из объекта JSON в MySQL, но только последняя строка добавляется в базу данных. Есть ли решение, подобное "для каждой строки"?
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()
Объект JSON выглядит так и может вмещать от 5 до 50 записей одновременно
[{"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"}]
Ошибка в отступе в курсоре.execute. Вот фиксированный код
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()
Вы должны поместить INSERT
в цикл for
:
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"]))
