一沸伏、背景
因業(yè)務(wù)需要獲取風(fēng)險(xiǎn)經(jīng)濟(jì)事件并采取應(yīng)對(duì)措施边臼，但因?yàn)榉N種原因又疏忽于每天去查看財(cái)經(jīng)日歷，于是通過(guò)爬取金十?dāng)?shù)據(jù)網(wǎng)站并自動(dòng)推送到微信查看。
二拆祈、目標(biāo)實(shí)現(xiàn)

三恨闪、環(huán)境與工具
1、pycharm：python開(kāi)發(fā)IDE
2放坏、windows 窗口句柄獲取工具 https://www.jb51.net/softs/584495.html
四咙咽、實(shí)現(xiàn)思路
爬蟲(chóng)獲取風(fēng)險(xiǎn)事件，然后python通過(guò)句柄定位到微信窗口淤年，模擬鍵鼠操作本機(jī)微信客戶端發(fā)給好友（自己）钧敞，最開(kāi)始本來(lái)使用微信itchat庫(kù)，但是這個(gè)是基于微信網(wǎng)頁(yè)版麸粮，登錄幾次后微信提示：為了你的帳號(hào)安全,此微信號(hào)已不允許登錄網(wǎng)頁(yè)微信溉苛。你可以使用Windows微信或Mac。
