一：nodejs，jsdom环境安装
①去官网下载nodejs安装，
②npm install jsdom
③在node_modules文件夹里检查有没有jsdom文件夹，有则代表安装成功，将此路径复制下来在代码里使用。
二：登录Cookie的动态获取
如果是小批量的数据采集，可以直接把cookie保存到本地文件。如果是长期大批量采集，可以构建cookie池，具体根据自己的情况处理就行。构建cookie池的方式有很多，就不细说了，大家自行网上搜一下吧。
三：搜索采集脚本
#offset：翻页开始索引号；cookieStr：cookie字符串；kw：搜索关键字；
def setConfig(self , kw , cookieStr, offset):
self.question = kw
data1 = {'': self.question}
self.question = parse.urlencode(data1)
print(self.question)
self.parse_url = "/api/v4/search_v3?t=general&q" + self.question + "&correction=1&offset=" + str(offset) + "&limit=20&lc_idx=" + str(offset) + "&show_all_topics=0&time_zone=a_day"
self.use_url = 'https://www.zhihu.com/api/v4/search_v3?t=general&q' + self.question + '&correction=1&offset=' + str(offset) + '&limit=20&lc_idx=' + str(offset) + '&show_all_topics=0&time_zone=a_day'
self.cookie = cookieStr
#offset：翻页开始索引号；cookieStr：cookie字符串；kw：搜索关键字；
def get_headers(self, kw, cookieStr, offset):
self.setConfig(kw, cookieStr, offset)
star = 'd_c0='
end = ';'
cookie_mes = self.cookie[self.cookie.index(star):].replace(star, '')
cookie_mes = cookie_mes[:cookie_mes.index(end)]
f = "+".join(["101_3_2.0", self.parse_url, cookie_mes])
fmd5 = hashlib.new('md5', f.encode()).hexdigest()
with open('g_encrypt.js', 'r') as f:
ctx1 = execjs.compile(f.read(), cwd=r'C:\Program Files\nodejs\node_modules')#jsdom路径
encrypt_str = "2.0_%s" % ctx1.call('b', fmd5)
headers = {

'x-app-za': 'OS=Web',

"User-agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/89.0.4389.82 Safari/537.36",
"Cookie": self.cookie,
}
resp = requests.get(url=self.use_url, headers=headers)
fu = File_Utils("./text.txt")
fu.write_utils(resp.text, False, "utf8")
json_mes = json.loads(resp.text)
allDatas = json_mes['data']#获取的数据集合；根据需求进行相应的解析；
