微信機器人項目開發--python

1、外網穿透工具下載與注冊【http://ngrok.ciqiuwl.cn/】

 

 

 

2、公眾號審請

 

 

 

 

 

 

 

3、代碼編寫

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() 函數將所有子文本串聯起來，# 必須傳遞單個節點，而不是節點集。
        if '查看全文' in  content:  # 忽略包含“查看原文”笑話
            continue
        jokes.append(content)
    joke = jokes[randint(1, len(jokes))].strip()
    return joke

if __name__ == "__main__":
    content = get_joke()
    print(content)



結果：

看到好友動態一個治腳氣的偏方晚上我准備調配好給老公泡腳，剛放姜片，鹽和醋，我女兒跑過來正好看見我拉着她爸爸的腳往盆里放，

盆里還有調料淌着哈喇子蹲下來就問我：麻麻，我們晚上吃爸爸腳丫子呀😂

查詢天氣接口
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)
    # 檢測城市天氣是否存在
    try:
        city_name = tree.xpath('//dd[@class="name"]/h2/text()')[0]
    except:
        content = '沒有該城市天氣信息，請確認查詢格式'
        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}天氣\n當前溫度：{2}\n今日天氣：{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)

結果：

【北京】2020年09月01日　星期二　庚子年七月十四 天氣
當前溫度：21℃
今日天氣：多雲18 ~ 32℃
濕度：64%
風向：東北風 1級
紫外線：無
空氣質量：優
PM: 5

 

啟動flask服務

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)
