PHP开发微信公众号文章付费阅读功能!
如上图,一看就懂,就是一片公众号文章,点进去显示标题,作者,时间,公众号名称和部分内容,要想阅读所有内容,那就支付0.01元就可以阅读所有的内容,这就是付费阅读!!!当然金额可以自定义....
其实这个开发原理很简单,无非就是在文章页面加一个微信支付的按钮,点击支付后把隐藏的部分给显示出来或者直接跳转到全文地址。
当然了,这个文章界面也是模仿官方来写的,你可以查看官方的样式,然后模仿就可以了,这个没啥难度。主要是加个按钮在这个页面,下面是这个页面的代码:
readpay.php
?phpheader('Content-tyPE:text/htML;
Charset=utf-8');
$mchid = '微信支付商户号';
//微信支付商户号$appid = '微信支付申请对应的公众号的APPID';
//微信支付申请对应的公众号的APPID$appKey = '微信支付申请对应的公众号的APPSECRET';
//微信支付申请对应的公众号的APPSECRET$apiKey = 'API密钥';
//帐户设置-安全设置-API安全-API密钥-设置API密钥//①、获取用户openid$wxpay = new WxpayService($mchid,$appid,$appKey,$apiKey);
$openId = $wxPay->
GetOpenid();
//获取openidif(!$openId) exIT('获取openid失败');
//②、统一下单$outTradeNo = uniqid();
//你自己的商品订单号$payAmount = 0.01;
//付款金额,单位:元$orderName = 'test';
//订单标题$notifyUrl = 'nofity.php';
//付款成功后的回调地址,一般放在本页面的同级目录即可$payTime = time();
//付款时间$jsApiParameters = $wxPay->
createjsBizPackage($openId,$payAmount,$outTradeNo,$orderName,$notifyUrl,$payTime);
$jsApiParameters = json_encode($jsApiParameters);
?>

简单说明:
1、新建readpay.php,拷贝上面的代码,修改商户号、appid、appsecret、密钥即可,还有下面的回调地址的路径(nofity.php),至于支付成功和支付失败跳转的页面按自己的需求修改即可。
支付金额、文章标题】时间、作者、公账号名称等根据自己的需求修改。
要注意,订单标题不能为中文,否则会提示body参数错误什么的。
2、新建nofity.php
把上面的代码拷贝上去,修改商户号、appid、密钥即可。
上传到支付授权目录,然后访问readpay.php页面测试。
3、新建false.html,这个是支付失败的页面,至于支付失败要显示什么或者输出什么,这个根据你的业务来自定义开发。
