easywechat之微信支付--在thinkPHP5中的使用

1. 准备工作

1.1 easywechat 安装完成

未安装移步至 -> http://www.cnblogs.com/flyphper/p/8484600.html

1.2 确定支付相关的配置参数已经配置好

<?php

return [
    /**
     * Debug 模式，bool 值：true/false
     *
     * 当值为 false 时，所有的日志都不会记录
     */
    \'debug\'  => true,
    /**
     * 账号基本信息，请从微信公众平台/开放平台获取
     */
    \'app_id\'  => \'\',         // AppID
    \'secret\'  => \'\',     // AppSecret
    \'token\'   => \'\',          // Token
    \'aes_key\' => \'\',                    // EncodingAESKey，安全模式下请一定要填写！！！
    /**
     * 日志配置
     *
     * level: 日志级别, 可选为：
     *         debug/info/notice/warning/error/critical/alert/emergency
     * permission：日志文件权限(可选)，默认为null（若为null值,monolog会取0644）
     * file：日志文件位置(绝对路径!!!)，要求可写权限
     */
    \'log\' => [
        \'level\'      => \'debug\',
        \'permission\' =>  0777,
        \'file\'       =>  LOG_PATH.\'easywechat.log\',
    ],
    /**
     * OAuth 配置
     *
     * scopes：公众平台（snsapi_userinfo / snsapi_base），开放平台：snsapi_login
     * callback：OAuth授权完成后的回调页地址
     */
    \'oauth\' => [
        \'scopes\'   => [\'snsapi_userinfo\'],
        \'callback\' => \'home/oauthallback\',
    ],
    /**
     * 微信支付
     */
    \'payment\' => [
        \'merchant_id\'        => \'\', // 商户号
        \'key\'                => \'\',
        \'cert_path\'          => \'\', // XXX: 绝对路径！！！！(前往微信公众平台上下载)
        \'key_path\'           => \'\',      // 同上
        // \'device_info\'     => \'\',
        // \'sub_app_id\'      => \'\',
        // \'sub_merchant_id\' => \'\',
        // ...
    ],
    /**
     * Guzzle 全局设置
     *
     * 更多请参考： http://docs.guzzlephp.org/en/latest/request-options.html
     */
    \'guzzle\' => [
        \'timeout\' => 3.0, // 超时时间（秒）
        \'verify\' => true
    ]
];

2. 支付操作

2.1 添加订单

wechat1.php

<?php
/**
 * ======================================
 *
 * Created by Super Demon W.
 * Author: \/Lin\/ 764582547@qq.com
 * Date: 2018/2/22
 * Time: 17:09
 *
 * =======================================
 */
namespace app\home\logic;

use think\Model;
use EasyWeChat\Foundation\Application;
use EasyWeChat\payment\Order;
use think\Config;

class Wechat1 extends Model {
    /**
     * 支付准备
     * @param $data
     * @param $openid
     * @return array
     */
    public function WeixinPrePay($data, $openid) {
        $options = Config::get(\'wechat\');
        $app = new Application($options);
        $payment = $app->payment;
        $attributes = [
            \'body\' => \'***-充值\',
            \'out_trade_no\' => $data[\'order_sn\'],
            \'total_fee\' => $data[\'money\']*100,
            #\'spbill_create_ip\' => \'***\',
            \'notify_url\' => url(\'**/notify\'), // 回调地址
            \'trade_type\' => \'JSAPI\',
            \'openid\' => $openid,
        ];

        $order = new Order($attributes);
        $result = $payment->prepare($order);
        if ($result->return_code == \'SUCCESS\' && $result->result_code == \'SUCCESS\') {
            $prepayId = $result->prepay_id;
            $json = $payment->configForPayment($prepayId);
            return [\'status\' => 200, \'msg\' => \'\', \'data\' => $json];
        } else {
            return [\'status\' => 400, \'msg\' => \'调起支付失败，请稍后尝试\'];
        }
    }
}

2.2 添加订单后调起支付

towxpay.php

namespace app\home\controller;
use app\home\logic\Wechat1;
use think\Session;
use think\Db;

public function towxpay() {
        $uid = Session::get(\'user_auth\')[\'uid\'];
        $money = input(\'recharge_money\', \'\');
        $wechat = new Wechat1();
        $order_sn = MakeOrderSn(); // 设置订单号
        # 添加订单
        $data = array(
                // ...yourdata
        );
        $order_id = db(\'order\')->insertGetId($data);
        if (!$order_id) {
            $this->error(\'订单添加失败\');
        }
        $openid = db(\'member\')->where(\'uid\', $uid)->value(\'openid\');
        $check = $wechat->WeixinPrePay($data, $openid);
        if ($check[\'status\'] == 400) {
             $this->error($check[\'msg\']);
        }
        session::set(\'zejc_order_id\', $order_id);
        $this->assign(\'jsonData\', $check[\'data\']);
        return $this->fetch();  
    }

2.3 调取支付页面

 towxpay.html

<html>
<head>
    <meta http-equiv="content-type" content="text/html;charset=utf-8"/>
    <meta name="viewport" content="width=device-width, initial-scale=1"/>
    <title>发起支付-支付</title>
    <script type="text/javascript">
        //调用微信JS api 支付
        function jsApiCall()
        {
            WeixinJSBridge.invoke(
                \'getBrandWCPayRequest\',{$jsonData},
                function(res){
                    if (res.err_msg == "get_brand_wcpay_request:ok") { // 支付成功
                        location.href = \'***?type=success\';
                    }
                    if(res.err_msg == "get_brand_wcpay_request:fail") { // 支付失败
                        location.href = \'***?type=fail\';
                    }
                    if (res.err_msg == "get_brand_wcpay_request:cancel") { // 取消支付
                        location.href = \'***?type=cancel\';
                    }
                }
            );
        }

        function callpay()
        {
            if (typeof WeixinJSBridge == "undefined"){
                if( document.addEventListener ){
                    document.addEventListener(\'WeixinJSBridgeReady\', jsApiCall, false);
                }else if (document.attachEvent){
                    document.attachEvent(\'WeixinJSBridgeReady\', jsApiCall);
                    document.attachEvent(\'onWeixinJSBridgeReady\', jsApiCall);
                }
            }else{
                jsApiCall();
            }
        }
        callpay();
    </script>
</head>
<body>
<div align="center" style="color: #00a157; margin-top: 20%">
    支付中...
</div>
</body>
</html>

 注: 统一下单后返回prepay_id后要调用小程序支付函数，有最重要的一步，是需要再次签名的，用统一下单返回的sign（签名）是没有用的。

================== 至此，微信支付结束 ===============
