python爬虫ajax爬取代码

以下是一个使用Python爬虫爬取Ajax请求数据的示例代码：

import requests

# 发送Ajax请求并获取数据
def get_ajax_data(url):
    headers = {
        'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/91.0.4472.124 Safari/537.36',
        'Referer': 'https://www.example.com'  # 根据实际情况设置Referer
    }
    response = requests.get(url, headers=headers)
    data = response.json()  # 解析JSON数据
    return data

# 下载图片
def download_image(url, filename):
    response = requests.get(url)
    with open(filename, 'wb') as f:
        f.write(response.content)

# 主函数
def main():
    # 发送Ajax请求并获取数据
    ajax_url = 'https://www.example.com/ajax'
    data = get_ajax_data(ajax_url)

    # 解析数据并下载图片
    for item in data:
        image_url = item['image_url']
        image_filename = item['image_filename']
        download_image(image_url, image_filename)

if __name__ == '__main__':
    main()

请注意，上述代码仅为示例，实际使用时需要根据具体的网站和Ajax请求进行相应的修改。
