Python读取JSON多行数据并批量插入MySQL数据库

核心代码实现与逻辑解析

import json
import pymysql

def reviewdata_insert(db):
  with open('data.txt', encoding='utf-8') as f:
    i = 0
    while True:
      i += 1
      print(u'正在载入第%s行......' % i)
      try:
        lines = f.readline() # 使用逐行读取的方法
        review_text = json.loads(lines) # 解析每一行数据
        result = []
        result.append((review_text['id'], review_text['created_at'], review_text['content'],
                review_text['source'], review_text['reports_count'], review_text['comments_count'],
                review_text['attitudes_count']))
        print(result)

        inesrt_re = "insert into review(id,created_at,content,source,reports_count,comments_count,attitudes_count) values(%s,%s,%s,%s,%s,%s,%s)"
        cursor = db.cursor()
        cursor.executemany(inesrt_re, result)
        db.commit()
      except Exception as e:
        db.rollback()
        print(str(e))
        break


if __name__ == "__main__": # 起到一个初始化或者调用函数的作用
  db = pymysql.connect("192.168.67.41", "root", "123456", "data", charset='utf8')
  cursor = db.cursor()
  reviewdata_insert(db)
  cursor.close()
