【移動(dòng)應(yīng)用開(kāi)發(fā)技術(shù)】C#實(shí)現(xiàn)微信公眾號(hào)群發(fā)消息的案例

這篇文章將為大家詳細(xì)講解有關(guān)C#實(shí)現(xiàn)微信公眾號(hào)群發(fā)消息的案例，在下覺(jué)得挺實(shí)用的，因此分享給大家做個(gè)參考，希望大家閱讀完這篇文章后可以有所收獲?？傮w思路：1.首先必須要在微信公眾平臺(tái)上申請(qǐng)一個(gè)公眾號(hào)。2.然后進(jìn)行模擬登陸。（由于我對(duì)http傳輸原理和編程不是特別懂，在模擬登陸的地方，不是特別清楚，希望有大神指教）3.模擬登陸后會(huì)獲得一個(gè)token（令牌）和cookie。4.因?yàn)槟M登陸后相當(dāng)于就進(jìn)入了微信公眾平臺(tái)，在這個(gè)里面就可以抓取到需要的數(shù)據(jù)，如公眾好友的昵稱(chēng)，fakeId。其中的fakeid非常重要，因?yàn)閭鬏敂?shù)據(jù)必須要知道對(duì)方的fakeid。5.知道對(duì)方的fakeid就可以進(jìn)行數(shù)據(jù)的發(fā)送了。不過(guò)里面還有一些小問(wèn)題，希望有人繼續(xù)修改和討論！也有人說(shuō)這樣會(huì)被封號(hào)，所以請(qǐng)謹(jǐn)慎操作講一下我項(xiàng)目里面的主要內(nèi)容1.WeiXinLogin.cs類(lèi)是用來(lái)執(zhí)行登陸功能的//對(duì)密碼進(jìn)行MD5加密
