python趣味挑戰(zhàn)之爬取天氣與微博熱搜并自動(dòng)發(fā)給微信好友
一、系統(tǒng)環(huán)境
1.python 3.8.2
2.webdriver(用于驅(qū)動(dòng)edge)
3.微信電腦版
4.windows10
二、爬取中國(guó)天氣網(wǎng)
因?yàn)橹袊?guó)天氣網(wǎng)的網(wǎng)頁(yè)是動(dòng)態(tài)生成的,所以不能直接爬取到數(shù)據(jù),需要先使用webdriver打開網(wǎng)頁(yè)并渲染完成,然后保存網(wǎng)頁(yè)源代碼,使用beautifulsoup分析數(shù)據(jù)。爬取的數(shù)據(jù)包括實(shí)時(shí)溫度、最高溫度與最低溫度、污染狀況、風(fēng)向和濕度、紫外線狀況、穿衣指南八項(xiàng)數(shù)據(jù)。
def getZZWeatherAndSendMsg(): HTML1='http://www.weather.com.cn/weather1dn/101190201.shtml' driver=webdriver.Edge() driver.get(HTML1) soup=BeautifulSoup(driver.page_source,'html5lib') #獲取實(shí)時(shí)溫度 tem=soup.find('span',class_='temp').string #獲取最高溫度與最低溫度 maxtem=soup.find('span',id='maxTemp').string mintem=soup.find('span',id='minTemp').string #獲取污染狀況 poll=soup.find('a',).string #獲取風(fēng)向和濕度 win=soup.find('span',id='wind').string humidity=soup.find('span',id='humidity').string #獲取紫外線狀況 sun=soup.find('div',class_='lv').find('em').string #獲取穿衣指南 cloth=soup.find('dl',id='cy').find('dd').string HTML2='http://www.weather.com.cn/weathern/101190201.shtml' driver.get(HTML2) soup=BeautifulSoup(driver.page_source,'html5lib') #獲取天氣情況 wea=soup.find_all('p',class_='weather-info')[1].string weatherContent='實(shí)時(shí)溫度:'+tem+'℃'+'\n'+'今日溫度變化:'+mintem+'~'+maxtem+'\n'+'今日天氣:'+wea+'\n'+'當(dāng)前風(fēng)向:'+win+'\n'+'相對(duì)濕度:'+humidity+'\n'+'紫外線:'+sun+'\n'+'污染指數(shù):'+poll+'\n'+'穿衣指南:'+cloth+'\n'+'注意天氣變化??!' driver.quit() return weatherContent
三、爬取微博熱搜
相比于中國(guó)天氣網(wǎng),微博熱搜要簡(jiǎn)單很多,直接request得到數(shù)據(jù)包,然后使用beautiful解析。解析數(shù)據(jù)后用for循環(huán)便利50次保存文本。
def getWeibo(): url='https://s.weibo.com/top/summary' headers={'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/90.0.4430.72 Safari/537.36 Edg/90.0.818.41'} r=requests.get(url,headers=headers) r.raise_for_status() r.encoding = r.apparent_encoding soup = BeautifulSoup(r.text, "html.parser") tr=soup.find_all('tr') weiboContent='今日微博熱榜:'+'\n' for i in range(2,52): text=tr[i].find('td',class_='td-02').find('a').string weiboContent=weiboContent+str(i-1)+'"'+text+'"'+'\n' return weiboContent
四、微信自動(dòng)發(fā)送消息
使用win32gui自動(dòng)化操作發(fā)送微信消息,首先使用微信的窗口名找到微信句柄,然后模擬鍵鼠搜索聯(lián)系人,打開聯(lián)系人窗口,發(fā)送消息并關(guān)閉窗口。同時(shí)發(fā)送多個(gè)聯(lián)系人時(shí)可以直接重復(fù)這幾步操作
if __name__=="__main__": target_a=['06:55','11:55','19:53'] target_b=['07:00','12:00','19:54'] name_list=['Squirrel B','Squirrel B'] while True: now=time.strftime("%m月%d日%H:%M",time.localtime()) print(now) if now[-5:] in target_a: base_weatherContent=getZZWeatherAndSendMsg() weiboContent=getWeibo() if now[-5:] in target_b: hwnd=win32gui.FindWindow("WeChatMainWndForPC", '微信') win32gui.ShowWindow(hwnd,win32con.SW_SHOW) win32gui.MoveWindow(hwnd,0,0,1000,700,True) time.sleep(1) for name in name_list: movePos(28,147) click() #2.移動(dòng)鼠標(biāo)到搜索框,單擊,輸入要搜索的名字 movePos(148,35) click() time.sleep(1) setText(name) ctrlV() time.sleep(1) # 等待聯(lián)系人搜索成功 enter() time.sleep(1) now=time.strftime("%m月%d日%H:%M",time.localtime()) weatherContent='現(xiàn)在是'+now+'\n'+base_weatherContent setText(weatherContent) ctrlV() time.sleep(1) altS() time.sleep(1) setText(weiboContent) ctrlV() time.sleep(1) altS() time.sleep(1) win32gui.PostMessage(hwnd, win32con.WM_CLOSE, 0, 0) time.sleep(60)
五、源代碼

六、運(yùn)行效果
七、總結(jié)
- 爬取中國(guó)天氣網(wǎng)數(shù)據(jù)
- 爬取微博熱搜
- 自動(dòng)發(fā)送微信消息
- 打包為exe并寫個(gè)簡(jiǎn)單的GUI
- 寫的比較簡(jiǎn)單,不過(guò)也夠用了,也懶得繼續(xù)寫下去了,希望可以供大家參考.
