python 实现微信发送消息

背景：利用Python来登入你个人的手机微信，之后向朋友发送消息，发送的消息可以来源于网页。下面的例子就是取得当前日元的汇率，之后发送自己的某一个朋友的手机上

环境：Python3，JetBrains PyCharm Community Edition 2018.2.4 x64，window7

实现的效果如下：

汇率的消息来源于网页

 

具体实现：

import json
from threading import Timer
from wxpy import *
import requests
import urllib.parse

def get_news():
    \'\'\'获取金山词霸每日一句\'\'\'
    url = \'http://open.iciba.com/dsapi\'
    r = requests.get(url)
    content = r.json()[\'content\']
    note = r.json()[\'note\']
    return content, note

def send_news():
    val = getRequest()
    mssage = u\'今天的日元汇率为:%s\' % val
    bot = Bot()  # 连接微信,会出现一个登陆微信的二维码
    try:
        # my_friends =bot.friends().search(u\'XXX\')[0]#这里是你微信好友的昵称
        friends = bot.friends()
        for i in friends:
            name = i
            if "XXX" == name.name:
                print(name)
            else:
                print(name)
                break
        # my_friend.send(contents[0])
        # my_friend.send(contents[1])
        name.send(mssage)
        t = Timer(86400, send_news)  # 这里是一天发送一次，86400s = 24h
        t.start()
    except:
        my_friend = bot.friends().search(\'filehelper\')[0]
        my_friend.send(u\'今天消息发送失败了\')

def getRequest():
    _header = getHeader()
    _data = urllib.parse.urlencode(getData()).encode(\'utf-8\')
    url = \'https://webapi.huilv.cc/api/trend/yaho\'
    response = requests.post(url, data=_data, headers=_header)

    print(response.encoding)
    print(response.apparent_encoding)
    r = response.text
    result_text = json.loads(r, encoding=\'utf-8\')
    val = result_text["obj"][len(result_text["obj"]) -1 ]["huilv"]
    return val

def getHeader():
    header = {
        \'Accept\': \'application/json, text/javascript, */*; q=0.01\',
        \'Content-Type\': \'application/x-www-form-urlencoded; charset=UTF-8\',
        \'Referer\': \'https://www.huilv.cc/zoushitu?a=JPYCNY&time=d1\',
        \'Sec-Fetch-Mode\': \'cors\',

    }
    return header

def getData():
    paydata = {
        \'pinzhong\': \'JPYCNY\',
        \'longs\': \'d1\'
    }
    return paydata

if __name__ == \'__main__\':
    get_news()
    send_news()
