thinkphp5+easywechat开发小程序支付


  1. composer下载thinkphp5   composer create-project topthink/think [你的目录名] --prefer-dist
  2. composer下载easywechat composer require hooklife/thinkphp5-wechat
  3. 配置好小程序的appid和appsercret,还有证书

第一步:
获取用户的openid

小程序代码
//app.js
App({
  onLaunch: function() {
   wx.login({
      success: function (res) {
        if (res.code) {
          //发起网络请求获得openid
          wx.request({
            url: 'https://xxxxxxxx/index/on_login/index',
            data: {
              code: res.code
            },
            success:function(res){
              //console.log(res.data.openid)
              that.globalData.openId = res.data.openid
            },
            fail:function(e){
              console.log(e);
            }
          })
        } else {
          console.log('获取用户登录态失败!' + res.errMsg)
        }
      }
    });
  }
})

php 代码
public function index(){

        $code = input('code');
        $appid = 'xxx';
        $appsecret = 'xxxx';
        //初始化
        $ch = curl_init();
        //设置选项,包括URL
        curl_setopt($ch, CURLOPT_URL, "https://api.weixin.qq.com/sns/jscode2session?appid={$appid}&secret={$appsecret}&js_code={$code}&grant_type=authorization_code");
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($ch, CURLOPT_HEADER, 0);
        //执行并获取HTML文档内容
        $output = curl_exec($ch);
        //释放curl句柄
        curl_close($ch);
        //打印获得的数据
        return $output;
    }

第二步:
发起微信支付
小程序代码
payMent:function(e){
    var that = this;
    wx.request({
      url: 'https://xxx/index/index/index.html',
      data:{
        'openid': app.globalData.openId,
        'total_money':1
      },
      success:function(res){
       wx.requestPayment({
         'timeStamp': res.data.timeStamp+'',
         'nonceStr': res.data.nonceStr,
         'package': res.data.package,
         'signType': 'MD5',
         'paySign': res.data.paySign,
         'success': function (ref) {
           console.log(ref);
           wx.showToast({
             title: '支付成功',
             icon: 'success',
             duration: 2000
           })
         },
         'fail': function (ref) {
           console.log(ref);
           wx.showToast({
             title: '支付失败',
             icon: 'fail',
             duration: 2000
           })
         }
       })
      }
    })
  },

public function index()
    {
        $app = Wechat::app();
        $payment = $app->payment;
        $openid = input('openid');
        $total_money = input('total_money/d');

        $attributes = [
            'trade_type'       => 'JSAPI', // JSAPI,NATIVE,APP...
            'body'             => 'iPad mini 16G 白色',
            'detail'           => 'iPad mini 16G 白色',
            'out_trade_no'     => time() . rand(1000, 9999),
            'total_fee'        => $total_money, // 单位:分
            'notify_url'       => 'https://xxx/index/index/order_notify.html', // 支付结果通知网址,如果不设置则会使用配置里的默认地址
            'openid'           => $openid, // trade_type=JSAPI,此参数必传,用户在商户appid下的唯一标识,
        ];
        $order = new Order($attributes);
        $result = $payment->prepare($order);
        $config = array();
        if ($result->return_code == 'SUCCESS' && $result->result_code == 'SUCCESS'){
            $prepayId = $result->prepay_id;
            $config = $payment->configForJSSDKPayment($prepayId);
        }
        $arr = array(
            'timeStamp'=>$config['timestamp'],
            'nonceStr'=>$config['nonceStr'],
            'package'=>$config['package'],
            'signType'=>'MD5',
            'paySign'=>$config['paySign'],
        );
        return json_encode($arr);
    }

    public function order_notify(){
        $app = Wechat::app();

        $response = $app->payment->handleNotify(function($notify, $successful){
            // 你的逻辑
            return true; // 或者错误消息
        });
        $response->send();
    }



总结:花了我一下午的时间来做支付,总的来说,逻辑很简单,就是各种配置很麻烦
