用python编写爬取海南招标网站中标公告的代码，爬取页数为10，字段为链接和标题和发布时间和中标金额和全文，并写入excel或csv，网址为https://www.ccgp-hainan.gov.cn/cgw/cgw_list.jsp

以下是用 Python 编写的爬取海南招标网站中标公告的代码，爬取页数为 10，字段为链接、标题、发布时间、中标金额和全文，并将结果写入 CSV 文件：

import requests
from bs4 import BeautifulSoup
import csv

url = 'https://www.ccgp-hainan.gov.cn/cgw/cgw_list.jsp'
params = {
    'currentPage': 1,
    'area': '',
    'industries': '',
    'noticesType': '',
    'noticesTitle': '',
    'noticesInfo': '',
    'agentName': '',
    'supplierName': '',
    'startTime': '',
    'endTime': '',
    'pageSize': 20,
    'pageCount': 10
}

headers = {
    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3'}

def get_data():
    data = []
    for i in range(1, params['pageCount'] + 1):
        params['currentPage'] = i
        response = requests.get(url, params=params, headers=headers)
        soup = BeautifulSoup(response.text, 'html.parser')
        table = soup.find('table', {'class': 'table'})
        rows = table.find_all('tr')[1:]
        for row in rows:
            cols = row.find_all('td')
            link = cols[1].find('a')['href']
            title = cols[1].find('a').text.strip()
            date = cols[2].text.strip()
            amount = cols[3].text.strip()
            content = get_content(link)
            data.append([link, title, date, amount, content])
    return data

def get_content(link):
    response = requests.get(link, headers=headers)
    soup = BeautifulSoup(response.text, 'html.parser')
    content = soup.find('div', {'class': 'content'}).text.strip()
    return content

def write_csv(data):
    with open('result.csv', 'w', newline='', encoding='utf-8-sig') as f:
        writer = csv.writer(f)
        writer.writerow(['链接', '标题', '发布时间', '中标金额', '全文'])
        writer.writerows(data)

if __name__ == '__main__':
    data = get_data()
    write_csv(data)

请注意，这个代码只是一个示例，实际使用时需要根据网站的具体情况进行修改。
