1. 在上节的基础上做修改，在上节源码中，根目录下在Shop/View文件夹下的order.html中的name改为username
2. 将更改根目录下在Shop/Controller文件夹下的IndexController.class.php为
~~~
<?php
namespace Shop\Controller;
use Think\Controller;
use Com\Wechat;
use Com\WechatAuth;
class IndexController extends Controller {
public function index(){
$m=M('goods');
$data=$m->select();
$this->assign('data',$data);
$this->display();
}
public function detail(){
$m=M('goods');
$data=$m->find($_GET['id']);
$this->assign('data',$data);
$this->display();
}
public function order(){
$this->assign('data',$_POST);
$this->display();
}
public function addOrder(){
header('Content-type:text/html;charset=utf-8');
if(empty($_GET['isnull'])){
header('Location:http://zyw.gzzysd.com/wxpay/example/jsapi.php');
$data['gid']=$_POST['id'];
$data['name']=$_POST['name'];
$data['username']=$_POST['username'];
$data['pirce']=$_POST['pirce']*$_POST['num'];
$data['num']=$_POST['num'];
$data['email']=$_POST['email'];
$data['mobile']=$_POST['mobile'];
$data['city']=$_POST['city'];
$data['detail']=$_POST['detail'];
session('data',$data);
}else{
$m=M('orders');
$res=$m->add(session('data'));
if($res){
echo '<script>alert("生成订单成功");location.href="http://zyw.gzzysd.com/index.php/Shop/Index";</script>';
}else{
echo '<script>alert("生成订单失败");history.go(-2)</script>';
}
}
}
}
~~~
3. 将根目录下的wxpay/example/jsapi.php更改为
~~~
<?php
session_start();//***
header('Content-type:text/html;charset=utf-8');
ini_set('date.timezone','Asia/Shanghai');
error_reporting(E_ERROR);
require_once "../lib/WxPay.Api.php";
require_once "WxPay.JsApiPay.php";
require_once 'log.php';
//初始化日志
$logHandler= new CLogFileHandler("../logs/".date('Y-m-d').'.log');
$log = Log::Init($logHandler, 15);
//打印输出数组信息//***
/*function printf_info($data)
{
foreach($data as $key=>$value){
echo "<font color='#00ff55;'>$key</font> : $value <br/>";
}
}*/
//①、获取用户openid
$tools = new JsApiPay();
$openId = $tools->GetOpenid();
//②、统一下单
$input = new WxPayUnifiedOrder();
$input->SetBody($_SESSION['data']['name']);//商品名称
$input->SetAttach($_SESSION['data']['name']);//附加参数
$input->SetOut_trade_no(WxPayConfig::MCHID.date("YmdHis"));//订单号
$input->SetTotal_fee($_SESSION['data']['pirce']*100);//支付金额
$input->SetTime_start(date("YmdHis"));
$input->SetTime_expire(date("YmdHis", time() + 600));
$input->SetGoods_tag("test");
$input->SetNotify_url("http://zyw.gzzysd.com/wxpay/example/notify.php");//支付验证链接
$input->SetTrade_type("JSAPI");
$input->SetOpenid($openId);
$order = WxPayApi::unifiedOrder($input);
//echo '<font color="#f00"><b>统一下单支付单信息</b></font><br/>';//***
//printf_info($order);//***
$jsApiParameters = $tools->GetJsApiParameters($order);
//获取共享收货地址js函数参数
$editAddress = $tools->GetEditAddressParameters();
//③、在支持成功回调通知中处理成功之后的事宜，见 notify.php
/**
* 注意：
* 1、当你的回调地址不可访问的时候，回调通知会失败，可以通过查询订单来确认支付是否成功
* 2、jsapi支付时需要填入用户openid，WxPay.JsApiPay.php中有获取openid流程 （文档可以参考微信公众平台“网页授权接口”，
* 参考http://mp.weixin.qq.com/wiki/17/c0f37d5704f0b64713d5d2c37b468d75.html）
