时间:2021-12-10 12:19:34

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 ===============
