获取速卖通的管产品搜索关键词!!

就是获取这个关键词!!

首先我们要查看相关的链接比如:

到这里我们已经看到了链接 请求参数 和 返回内容 开始写代码

# 首先我们先构建一下需要的参数 根据我的观察 参数的主要变化 在 "t" "sign" 和 "data"中的nkey urldata = { 'jsv': "2.5.1", 'appKey': 24815441, 't': tim, 'sign': sign, 'api': "mtop.relationrecommend.AliexpressRecommend.recommend", 'v': "1.0", 'type': "jsonp", 'dataType': "jsonp", 'callback': 'mtopjsonp10', 'data': '{"appId":18390,"params":"{\\"query\\":\\"' + str(nkey) + '\\",\\"userMemberSeq\\":\\"\\",\\"language\\":\\"es\\",\\"site\\":\\"esp\\",\\"shipToCountry\\":\\"US\\",\\"shipToCity\\":\\"\\",\\"clientType\\":\\"pc\\",\\"cookieId\\":\\"YRsUF5pqAkgCAbegKYZu6mi2\\",\\"statusOfUsingPrivacy\\":\\"\\"}"}', } # 链接是这样的 from urllib.parse import urlencode nurl = 'https://acs.aliexpress.com/h5/mtop.relationrecommend.aliexpressrecommend.recommend/1.0/?' + urlencode(urldata) # 好的 这个时候我们构建我们的请求头 我发现这个请求下 只要带 三个参数就可以 这里构建了两个还要带一个cookies Headers = { 'referer': 'https://es.aliexpress.com/', 'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/81.0.4044.138 Safari/537.36' } # cookies 的构建 其中cookise 构建中 主要是 '_m_h5_tk' 和 '_m_h5_tk_enc' 参数 其他的请求一次 # 首页的 链接就可以获取 Cookies = { 'acs_usuc_t': 'x_csrf=__0k270ux3o4&acs_rt=f562c439078c43d2acbdfbd3b7b8e3a8', 'aep_usuc_f': 'site=esp&c_tp=EUR®ion=CN&b_locale=es_ES', 'ali_apache_id': '11.134.216.25.1591593362612.216173.7', 'intl_common_forever': 'heBSREitqKC8WPb/iKHwfcN7FsgWoV4+96wqRRzSa3vV7DZwrzDWMQ==', 'intl_locale': 'es_ES', 'xman_f': 'nUnPy5ggUBRUf2Tl0SgyHkKxkYHqoVwVihs99/cZ1eZPM7BsDol2HQYEpcDBMpfBmPEoCol19jx5d3EUm0jGXN/1KWZfKiDxCM6SaRLSOm9u2rR6qgXwhA==', 'xman_t': 'nYK387MYVfRBNgTcRS1WT2V8JRQaIv5dzZaJxIJP7TYK28++X6DxfH5ZszSYx8Xs', 'xman_us_f': 'x_locale=es_ES&x_l=1&x_c_chg=1&x_as_i={"aeuCID":"","cookieCacheEffectTime":1591593662622,"isCookieCache":"Y","ms":"0"}&acs_rt=f562c439078c43d2acbdfbd3b7b8e3a8', # 以上的cookies 是访问 requests.get('https://es.aliexpress.com/') 获取的 '_m_h5_tk': '52ba79e8346419e689a1ace28bdde23a_1591766715829', '_m_h5_tk_enc': '437fa68b6379b4bf35c01a03c0b1adca' } # 完是具备 开始请求 response = requests.request("POST", nurl, headers=Headers, cookies=Cookies) # 查看返回结果 print(response.text)

好的主要的程序已经写完啦 接下来 获取相关的参数哦

# 主要参数就是那个 sign ,而这个sign 是js形成的 首先要找到这个sign 形成的js 代码段

我们已经找到了代码段 这个代码段 是静态的 copy 了下来 保存成了Crack.js 文件
