微信机器人项目开发--python

1、外网穿透工具下载与注册【http://ngrok.ciqiuwl.cn/】

2、公众号审请

3、代码编写

糗事百科接口
# _*_ coding:utf-8   _*_
import requests
from lxml import etree
from random import randint
 
def get_joke():
    url="http://www.qiushibaike.com/text/page/"+ str(randint(1,5))
    r = requests.get(url)
    tree = etree.HTML(r.text)
    contentlist = tree.xpath('//div[@class="content"]/span')
    jokes = []
    for content in contentlist:
        content = content.xpath('string(.)') # string() 函数将所有子文本串联起来，# 必须传递单个节点，而不是节点集。
        if '查看全文' in  content:  # 忽略包含“查看原文”笑话
            continue
        jokes.append(content)
    joke = jokes[randint(1, len(jokes))].strip()
    return joke
 
if __name__ == "__main__":
    content = get_joke()
    print(content)

结果：

看到好友动态一个治脚气的偏方晚上我准备调配好给老公泡脚，刚放姜片，盐和醋，我女儿跑过来正好看见我拉着她爸爸的脚往盆里放，

盆里还有调料淌着哈喇子蹲下来就问我：麻麻，我们晚上吃爸爸脚丫子呀

查询天气接口
import requests
from lxml import etree
 
def get_weather(keyword):
    url = 'https://www.tianqi.com/tianqi/search?keyword=' + keyword
    headers = {
        'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/68.0.3440.106 Safari/537.36'
    }
    response = requests.get(url,headers=headers)
    tree = etree.HTML(response.text)
    # 检测城市天气是否存在
    try:
        city_name = tree.xpath('//dd[@class="name"]/h2/text()')[0]
    except:
        content = '没有该城市天气信息，请确认查询格式'
        return content
    week = tree.xpath('//dd[@class="week"]/text()')[0]
    now = tree.xpath('//p[@class="now"]')[0].xpath('string(.)')
    temp = tree.xpath('//dd[@class="weather"]/span')[0].xpath('string(.)')
    shidu = tree.xpath('//dd[@class="shidu"]/b/text()')
    kongqi = tree.xpath('//dd[@class="kongqi"]/h5/text()')[0]
    pm = tree.xpath('//dd[@class="kongqi"]/h6/text()')[0]
    content = "【{0}】{1}天气\n当前温度：{2}\n今日天气：{3}\n{4}\n{5}\n{6}".format(city_name, week.split('\u3000')[0], now, temp, '\n'.join(shidu),kongqi,pm)
    return content
 
if __name__ == "__main__":
    keyword = '北京'
    content = get_weather(keyword)
    print(content)

结果：

【北京】2020年09月01日　星期二　庚子年七月十四 天气
当前温度：21℃
今日天气：多云18 ~ 32℃
湿度：64%
风向：东北风 1级
紫外线：无
空气质量：优
PM: 5

启动flask服务
 
from flask import Flask
 
app = Flask(__name__)
@app.route('/')
def hello():
    return 'Hello World'
 
if __name__ == "__main__":
    app.run(host='127.0.0.1', port=8088,debug=True)
