Final effect

Not much nonsense, just go to the picture
Python realizes crawling Weibo hot searches and storing them in Mysql
Here you can clearly see that the database contains date, content, and website link
Let’s analyze how to implement it

Library used

import requests from selenium.webdriver import Chrome, ChromeOptions import time from sqlalchemy import create_engine import pandas as pd

Copy after login

Target analysis

This is a hotly searched link on Weibo: Click me to go to the target webpage
Python realizes crawling Weibo hot searches and storing them in Mysql
First we use selenium to request the target web page
Then we use xpath to locate the web page elements and traverse to obtain all the data
Then use pandas to generate a Dataframe object and store it directly in the database

1: Get data

Python realizes crawling Weibo hot searches and storing them in Mysql
We see that 51 pieces of data can be obtained using xpath. These are the hot searches, from which we can get the links and Title content

all = browser.find_elements_by_xpath('//*[@id="pl_top_realtimehot"]/table/tbody/tr/td[2]/a') #得到所有数据 context = [i.text for i in c] # 得到标题内容 links = [i.get_attribute('href') for i in c] # 得到link

Copy after login

Then we use the zip function to merge date, context, and links
The zip function combines several lists into one list, and merges the data in the list into one tuple by index. , this can produce pandas objects.

dc = zip(dates, context, links) pdf = pd.DataFrame(dc, columns=['date', 'hotsearch', 'link'])

Copy after login

The date can be obtained using the time module

2: Link to the database

This is very easy

enging = create_engine("mysql+pymysql://root:123456@localhost:3306/webo?charset=utf8") pdf.to_sql(name='infromation', con=enging, if_exists="append")

Copy after login

Total Code

from selenium.webdriver import Chrome, ChromeOptions import time from sqlalchemy import create_engine import pandas as pd def get_data(): url = r"https://s.weibo.com/top/summary" # 微博的地址 option = ChromeOptions() option.add_argument('--headless') option.add_argument("--no-sandbox") browser = Chrome(options=option) browser.get(url) all = browser.find_elements_by_xpath('//*[@id="pl_top_realtimehot"]/table/tbody/tr/td[2]/a') context = [i.text for i in all] links = [i.get_attribute('href') for i in all] date = time.strftime("%Y-%m-%d-%H_%M_%S", time.localtime()) dates = [] for i in range(len(context)): dates.append(date) # print(len(dates),len(context),dates,context) dc = zip(dates, context, links) pdf = pd.DataFrame(dc, columns=['date', 'hotsearch', 'link']) # pdf.to_sql(name=in, con=enging, if_exists="append") return pdf def w_mysql(pdf): try: enging = create_engine("mysql+pymysql://root:123456@localhost:3306/webo?charset=utf8") pdf.to_sql(name='infromation', con=enging, if_exists="append") except: print('出错了') if __name__ == '__main__': xx = get_data() w_mysql(xx)
