爬取微博热搜

    我这里使用Python的正则表达式进行爬取,这虽然是一种原始的方式,但是应对简单的爬虫任务时却很有效。首先打开微博热搜的页面:https://d.weibo.com/231650_ctg1_-_all#。然后F12进入调试模式。接着根据想要爬去的内容定位到网页元素,对于想要爬取热搜的话,可以定位到<ul class="pt_ul clearfix">这里,标签包含了我们想要的内容。

    下一步,切换到Network窗口,点击网页刷新,找到网页内容文件。经过查找,发现在Doc内容的231650_ctg1_-_all里面。查看该文件的请求头的内容,写代码的时候需要用到。下面是Python的代码:

邮件发送

    这里直接按照菜鸟教程的Python邮件发送教程来,使用QQ邮箱作为SMTP作为邮件发送服务器。SMTP(Simple Mail Transfer Protocol)即简单邮件传输协议,它是一组用于由源地址到目的地址传送邮件的规则,由它来控制信件的中转方式。python的smtplib提供了一种很方便的途径发送电子邮件。它对smtp协议进行了简单的封装。这里需要在QQ邮箱里的"设置->帐号管理->开启POS3/SMTP服务->获得授权码",将授权码作为登录的密码,得到的代码如下:

#!/usr/bin/python
# -*- coding: UTF-8 -*-
 
import smtplib
from email.mime.text import MIMEText
from email.utils import formataddr
 
my_sender='[email protected]'    # 发件人邮箱账号
my_pass = 'xxx'    # 发件人邮箱密码
my_user='[email protected]'    # 收件人邮箱账号
def mail():
    ret=True
    try:
        msg=MIMEText('邮件内容:测试','plain','utf-8')
        msg['From']=formataddr(["AlexChen",my_sender])  # 括号里的对应发件人邮箱暱称、发件人邮箱账号
        msg['To']=formataddr(["JianquChen",my_user])              # 括号里的对应收件人邮箱暱称、收件人邮箱账号
        msg['Subject']="邮件测试"                # 邮件的主题,也可以说是标题
 
        server=smtplib.SMTP_SSL("smtp.qq.com", 465)  # 发件人邮箱中的SMTP服务器,端口是25
        server.login(my_sender, my_pass)  # 
        server.sendmail(my_sender,[my_user,],msg.as_string())  
        server.quit()  # 关闭连接
    except Exception:  
        ret=False
    return ret
 
ret=mail()
if ret:
    print("邮件发送成功")
else:
    print("邮件发送失败")

    更正:这爬的好像不是热搜,,,但这是不是重点。

 

 

爬取天气预报

    直接使用<树莓派智能家居-天气预报和实时温湿度监控>的代码获取天气预报。如下:

import requests
import json
def getWeather(city,date=0):
    s=''
    rb=requests.get('http://wthrcdn.etouch.cn/weather_mini?city='+city)
    #print(rb.text)
    data=json.loads(rb.text)
    if(data['status']==1000):
        d=data['data']
        if(date==0):
            s+=d['city']+'今天'+d['forecast'][0]['type']+','
            s+=d['forecast'][0]['low'][2:]+'到'+d['forecast'][0]['high'][2:]+','
            s+=d['forecast'][0]['fengxiang']+d['forecast'][0]['fengli'][8:]+','
            s+='当前室外温度:'+d['wendu']+'度,'
            s+=d['ganmao']
        elif(date>0 and date<5):
            s+=d['city']
            if(date==1):
                s+='明天'
            elif(date==2):
                s+='后天'
            else:
                s+=d['forecast'][date]['date']
            s+=d['forecast'][date]['type']+','
            s+=d['forecast'][date]['low'][2:]+'到'+d['forecast'][date]['high'][2:]+','
            s+=d['forecast'][date]['fengxiang']+d['forecast'][date]['fengli'][8:]
        elif(date==-1):
            s+=d['city']+'昨天'+d['yesterday']['type']+','
            s+=d['yesterday']['low'][2:]+'到'+d['yesterday']['high'][2:]+','
            s+=d['yesterday']['fx']+d['yesterday']['fl'][8:]
    else:
        s='天气请求失败'
    return s
print(getWeather("钦州市",date=0))
