    php开发微信公众号收费模块插图源码资源库
    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

    <?php
    header('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 = $wxPay->GetOpenid();      //获取openid
    if(!$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);
    ?>
