基金漲幅監控之python爬蟲

年後被朋友帶入基金的坑，天天說暴漲，各種牛市。於是小白的我就入坑了，稀裏糊塗的買了幾個。結果還沒上車兩天，突然暴跌，內心慘痛。每天在支付寶裏面點擊各個基金看當日漲幅感覺太繁瑣，於是用python寫了個腳本，這樣方便看下。當然還是不看的好，這樣你就能忘記傷痛。 

這邊爬的天天基金的數據，不過這個數據和當日收益還是會有點出入。但大體差不多，除了原油基金！！！（吐嘈易方達原油）

下面附上代碼

import datetime
import requests
from requests.exceptions import RequestException
from pyquery import PyQuery as pq

def get_one_page(url):
    try:
        headers = {
            'User-Agent': 'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/67.0.3396.62 Safari/537.36'
        }
        response = requests.get(url,headers=headers)
        if response.status_code == 200:
            response.encoding = 'utf-8'
            return response.text
        return None
    except RequestException:
        return None


def spider(fund_id):
    url = 'http://fund.eastmoney.com/%s.html' % fund_id
    html = get_one_page(url)
    if html!=None:
        doc = pq(html)
        name = doc('#body > div:nth-child(12) > div > div > div.fundDetail-header > div.fundDetail-tit > div').text()
        value = doc('#gz_gszzl').text()
        return name, value

if __name__ == '__main__':

    result = {}

    fund_id = {'004348','005911'} ###這邊改爲你的基金代碼
    for id in fund_id:
        name,value = spider(id)
        result[name] = value
    now = datetime.datetime.now()
    print(now)
    result1 = sorted(result.items(),key=lambda x:x[1])
    for fund in result1:
        print(fund[1]+'\t'+fund[0])

大概結果將就是這樣，注意是Python3的腳本
