本文介绍如何通过Python爬取阿里国际站商品详情页的数据，包括设置请求头、使用正则表达式匹配JSON数据及提取商品价格等关键信息。

我们首先打开网页做分析

按下F12点击Network找到headers，将Cookie和User-agent复制下来，留着备用！

import requests
def get_html(url):
    cookie = 'ali_apache_id=11.134.216.25.1620641275908.387521.9; cna=hyANGQQpnwUCAXFZBo1X/gL1; _bl_uid=eekXnoe0ihCgpa1FCqstxaXlIdkv; _gcl_au=1.1.1881464747.1620641406; ali_apache_track=; _fbp=fb.1.1621326157853.591747728; aep_usuc_f=site=bra&c_tp=USD&region=FR&b_locale=pt_BR; xman_t=d3qKco3s8ICw0nzaQKKtoS0U3oTdStKANNGzQcVE34kW5GawHBvg/8Wm4LzqG4xI; xman_f=fnzcTB4lMyXcsSfeOLZLF5TbjbvZnCw91SwcXqHWKK7CkNjRWPpgKzvfCNZ9xbOsS/SPDnilWQxS893RyPst+aDmE9cIkUu1pvV2cEdRTCqbr63Zf8uKfA==; _gid=GA1.2.2062164804.1627263915; xman_us_f=x_locale=pt_BR&x_l=1&x_c_chg=0&x_as_i=%7B%22cookieCacheEffectTime%22%3A1627270529699%2C%22isCookieCache%22%3A%22Y%22%2C%22ms%22%3A%220%22%7D&acs_rt=baf2bdbceea74f888cbbdd265264b7ab; xlly_s=1; acs_usuc_t=x_csrf=55vc73s5jut0&acs_rt=38423a3343ad45c8b2fd8041c440e02e; x5sec=7b2261652d676c6f64657461696c2d7765623b32223a223838373335363436356566383139623064376432343632616538356431663837434c4b6569496747454c6a4672704b346c71376833674577752f4f353950722f2f2f2f2f41513d3d227d; intl_locale=pt_BR; intl_common_forever=EZ/MhgYRW2l3kU7xfsuyidNeG/9B8oNGqiGWzG457Ix5vegmIyy/9A==; _m_h5_tk=ccb5c1ef7baef073e284453a0d30a16d_1627532837402; _m_h5_tk_enc=431c18c4496c660d8cea1a9ad4f23af5; XSRF-TOKEN=b6eae551-3789-4a09-8b34-2546192807c2; JSESSIONID=C750362F52F72C63AA239A47647FA8B3; tfstk=cJ5OB7qRUkqM33TdzOe3hCO1qyBOZK09mVtxMPzpowP8BHlAi-5lw1eYCEo99yC..; l=eBLVX5SPjAzjolMsBOfwnurza77OsIRAguPzaNbMiOCPOVC958yAB6hqONLpCnGVh6jMR3Rj4pR2BeYBqIvQ_uwxKn-yLLMmn; isg=BPX1p04g-Lbs4x2R4ctyrIJPBHGvcqmEz8EwaXcavGy7ThVAP8bFVZXMnBL4DsE8; _gat=1; _ga_VED1YSGNC7=GS1.
