国内股票爬取(简易版)+CSV 存储(一次性)（尝试版）
现在使用 雪球网 对股票的各项数值进行爬取
雪球网中爬取的信息存储比较奇怪，需提取 其中字典，在这里使用提取沪市的部分股票为例，由于雪球网的数据基本可通过 关键词搜索 索引+1 来获取，所以在这里我就用简易XPath
注意：之前选择正则取数据有坑，因为其数据的text分布不同，所以最好用查找关键词的方法筛选自己想要的数据。
这是主要提取元素的方法，其中的URL 也可以使用科技股和其他股的，因为检索的索引关键词是一样的：

调用主函数，其中的股票列表可替换或用input自己添加：
这里每30秒记录一次，但是这里记录时间会不一样
if __name__ == '__main__': # stock = input("请输入您的股票：") stock_list = ['688157', '600018', '600072', '600635', '600497', '603658', '688208', '600550', '600498', '600703', '603815', '600127', '600305', '603777', '688004'] headers = { "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/73.0.3683.75 Safari/537.36"} # stock_list.append(stock) writer_ss = write_to_csv_header() # get_website() # 循环 scheduler = BlockingScheduler() scheduler.add_job(func=get_website, trigger='interval', seconds=30) scheduler.start()
写入csv函数：（好丑）还是有键名
