這篇文章主要介紹了Python下載商品數(shù)據(jù)并連接數(shù)據(jù)庫且保存數(shù)據(jù)，包括發(fā)送請求、獲取數(shù)據(jù)、解析數(shù)據(jù)(篩選數(shù)據(jù))、保存數(shù)據(jù)、連接數(shù)據(jù)庫等內(nèi)容，需要的小伙伴可以參考一下

前言：

開發(fā)環(huán)境：

  • python 3.8
  • pycharm 2021.2 專業(yè)版

代碼實現(xiàn)：

  • 發(fā)送請求
  • 獲取數(shù)據(jù)
  • 解析數(shù)據(jù)(篩選數(shù)據(jù))
  • 保存數(shù)據(jù)
  • 連接數(shù)據(jù)庫

請求數(shù)據(jù)

獲取數(shù)據(jù)

解析數(shù)據(jù)(篩選數(shù)據(jù))

# 字符串 肯定不能用 字典方式鍵值對取值
# json_str: 字符串
# 類型轉(zhuǎn)變: 轉(zhuǎn)成字典類型 才能通過鍵值對方式去取值

? ? view_sales = auction['view_sales']
? ? nick = auction['nick']
? ? print(raw_title, pic_url, detail_url, view_price, item_loc, view_sales, nick)

保存數(shù)據(jù)

連接數(shù)據(jù)庫

import pymysql

def save_sql(title, pic_url, detail_url, view_price, item_loc, view_sales, nick):
? ? count = pymysql.connect(
? ? ? ? host='xxx.xxx.xxx.xxx', ?# 數(shù)據(jù)庫地址
