這篇文章將為大家詳細(xì)講解有關(guān)如何使用PHP開發(fā)微信公眾號(hào)文章付費(fèi)閱讀功能,小編覺得挺實(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。
php開發(fā)微信公眾號(hào)文章付費(fèi)閱讀功能!
如上圖,一看就懂,就是一片公眾號(hào)文章,點(diǎn)進(jìn)去顯示標(biāo)題,作者,時(shí)間,公眾號(hào)名稱和部分內(nèi)容,要想閱讀所有內(nèi)容,那就支付0.01元就可以閱讀所有的內(nèi)容,這就是付費(fèi)閱讀!??!當(dāng)然金額可以自定義....
其實(shí)這個(gè)開發(fā)原理很簡單,無非就是在文章頁面加一個(gè)微信支付的按鈕,點(diǎn)擊支付后把隱藏的部分給顯示出來或者直接跳轉(zhuǎn)到全文地址。
當(dāng)然了,這個(gè)文章界面也是模仿官方來寫的,你可以查看官方的樣式,然后模仿就可以了,這個(gè)沒啥難度。主要是加個(gè)按鈕在這個(gè)頁面,下面是這個(gè)頁面的代碼:

簡單說明:
1、新建readpay.php,拷貝上面的代碼,修改商戶號(hào)、appid、appsecret、密鑰即可,還有下面的回調(diào)地址的路徑(nofity.php),至于支付成功和支付失敗跳轉(zhuǎn)的頁面按自己的需求修改即可。
支付金額、文章標(biāo)題】時(shí)間、作者、公賬號(hào)名稱等根據(jù)自己的需求修改。
要注意,訂單標(biāo)題不能為中文,否則會(huì)提示body參數(shù)錯(cuò)誤什么的。
2、新建nofity.php
把上面的代碼拷貝上去,修改商戶號(hào)、appid、密鑰即可。
上傳到支付授權(quán)目錄,然后訪問readpay.php頁面測(cè)試。
3、新建false.html,這個(gè)是支付失敗的頁面,至于支付失敗要顯示什么或者輸出什么,這個(gè)根據(jù)你的業(yè)務(wù)來自定義開發(fā)。
