时间: 2023-10-13 22:06:15 浏览: 206
可以使用正则表达式和JavaScript的document.cookie属性来提取cookie。
例如,以下代码可以提取cookie中名为cf_clearance的值:
```
var regex = /cf_clearance=([^;]+)/;
var match = regex.exec(document.cookie);
var cf_clearance_value = match[1];
```
其中,regex是一个正则表达式,用来匹配cf_clearance的值。exec()方法返回一个数组,其中第一个元素是匹配到的字符串,第二个元素是第一个捕获组(即括号内的部分),以此类推。
需要提取其他cookie值,只需修改正则表达式的匹配部分即可。

可以使用正则表达式提取 cookie 字符串中的 `cf_chl_2` 字段。以下是一个提取的示例正则表达式:
```javascript
const cookieStr = 'cf_chl_2=; path=/; expires=Thu, Jan 01 1970 00:00:00 UTC; domain=.hapag-lloyd.cn; Secure cf_clearance=_bPJegR0K9V1oLHj1q6CodoEy.VtCIG.5blzf_apuo8-1685521974-0-1-52c890dc.a1562d2.5c9cf3c-150; path=/; expires=Thu, 30-May-24 08:33:17 GMT; domain=.hapag-lloyd.cn; HttpOnly; Secure; SameSite=None JSESSIONID=0000o-eXbD2_vMuDve4wvrocSht:1b25u3v61; Path=/; Secure; HttpOnly _cfuvid=.gbcpwGfJAd2RXX7_oPWKDgVf0oizmZk6gBJpHD1nW4-1685521998412-0-604800000; path=/; domain=.hapag-lloyd.cn; HttpOnly; Secure; SameSite=None';
const regex = /cf_chl_2=.*?(?=;)/;
const match = cookieStr.match(regex);
const cf_chl_2 = match ? match[0] : null;
console.log(cf_chl_2);
// Output: cf_chl_2=
```
上述正则表达式的含义是匹配以 `cf_chl_2` 开头,后面跟随任意字符直到遇到分号的子串。`(?=;)` 是一个正向预查,表示匹配结束位置是分号,但不包含分号在内。

好的,你想要爬取这个网站的源代码文本,我可以帮你写一个Python爬虫程序来实现。以下是代码实现:
```python
import requests
url = 'https://www.bbiquge.net/modules/article/search.php?searchkey=%B6%B7%C2%DE%B4%F3%C2%BD&submit=%CB%D1%CB%F7'
headers = {
'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/113.0.0.0 Safari/537.36 Edg/113.0.1774.57',
'referer': 'https://www.bbiquge.net/modules/article/search.php?searchkey=%B6%B7%C2%DE%B4%F3%C2%BD&submit=%CB%D1%CB%F7&__cf_chl_tk=sloS0pzp6d1uAnYpALHcgIKs4rWjKqzfIYD4OXgK2xQ-1685714391-0-gaNycGzNDBA',
'cookie': '__gads=ID=80441a18d01e55cc-226b809157da00ce:T=1677758715:RT=1685678040:S=ALNI_MboIk-dUvtHydPucNSQ4k0MMKgdqg; __gpi=UID=00000bcfc88d3faa:T=1677758715:RT=1685678040:S=ALNI_MbpuTSDhTgrw2mMv6PXbbCwD8b5AA; cf_chl_2=206d854953a2c39; cf_clearance=wLK7rF.9158UjsnSnRTVDdbk6Fc.9HIhB.p695uIhHA-1685712522-0-160; jieqiVisitTime=jieqiArticlesearchTime%3D1685713325; Hm_lvt_007bc30c1abb0ffb7a93b4f3c8e10c5e=1685343344,1685415712,1685674211,1685713326; Hm_lpvt_007bc30c1abb0ffb7a93b4f3c8e10c5e=1685713326'
}
response = requests.get(url, headers=headers)
if response.status_code == 200:
print(response.text)
else:
print('请求失败,状态码为:', response.status_code)
```
在这个程序中,我们使用了Python的requests库来发送HTTP请求,获取网页的源代码文本。其中,`url`是我们要爬取的网址,`headers`是我们发送请求时需要带上的请求头信息,包括User-Agent、Referer和Cookie等。我们使用requests.get()函数发送GET请求,并且通过判断响应状态码是否为200来判断请求是否成功。如果请求成功,我们就可以通过response.text属性来获取网页的源代码文本。
