        port=3306,  # 數(shù)據(jù)庫(kù)端口
        user='xxxx',  # 數(shù)據(jù)庫(kù)賬號(hào)
        password='xxxx',  # 數(shù)據(jù)庫(kù)密碼
        db='xxxx'  # 數(shù)據(jù)庫(kù)表名
    )
    # 創(chuàng)建數(shù)據(jù)庫(kù)對(duì)象
    db = count.cursor()
    # 寫入sql
    sql = f"insert into goods(title, pic_url, detail_url, view_price, item_loc, view_sales, nick) values ('{title}', '{pic_url}', '{detail_url}', {view_price}, '{item_loc}', '{view_sales}', '{nick}')"
    # 執(zhí)行sql
    db.execute(sql)
    # 保存修改內(nèi)容
    count.commit()
    db.close()
