第一步：下载官方PHP支付demo
第二步：将文件夹拷贝到thinkphp 框架文件的vendor中；
第三步：稍微修改源码，把PHP脚本改成类的形式；例；
class js_api_call extends \Think\Controller{
public function js_api_call(){
//构造方法
vendor ( ‘phpPay.WxPayPubHelper.WxPayPubHelper‘ );
}
public function goToPay($payid){
//使用jsapi接口
$jsApi = new \JsApi_pub();
//=========步骤1：网页授权获取用户openid============
//通过code获得openid
if (!isset($_GET[‘code‘]))
{
//触发微信返回code码
$url = $jsApi->createOauthUrlForCode(WxPayConf_pub::JS_API_CALL_URL,$payid);
Header("Location: $url");
}else
{
//获取code码，以获取openid
$code = $_GET[‘code‘];
$jsApi->setCode($code);
$openid = $jsApi->getOpenId();
}
//=========步骤2：使用统一支付接口，获取prepay_id============
//使用统一支付接口
//获取订单id
$orderids = $_GET[‘state‘];
$res = M(‘order‘)->where(‘id in (‘.$orderids.‘)‘)->select();
//计算价格 等等
$totle = 0;
$tradeNo = null;
$oid = null;
foreach($res as $row){
$totle += $row[‘totleprice‘];
$tradeNo[] = $row[‘tradeno‘];
$oid[] = $row[‘id‘];
}
$totle = $totle*100;
$oid = implode(‘,‘,$oid);
$unifiedOrder = new \UnifiedOrder_pub();
//设置统一支付接口参数
//设置必填参数
//appid已填,商户无需重复填写
//mch_id已填,商户无需重复填写
//noncestr已填,商户无需重复填写
//spbill_create_ip已填,商户无需重复填写
//sign已填,商户无需重复填写
//自定义订单号，此处仅作举例
$timeStamp = time();
$out_trade_no = WxPayConf_pub::APPID."$timeStamp";
$unifiedOrder->setParameter("openid","$openid");//商品描述
$unifiedOrder->setParameter("body","$out_trade_no");//商品描述
$unifiedOrder->setParameter("out_trade_no","$out_trade_no");//商户订单号
$unifiedOrder->setParameter("total_fee","$totle");//总金额
$unifiedOrder->setParameter("notify_url",WxPayConf_pub::NOTIFY_URL);//通知地址
$unifiedOrder->setParameter("trade_type","JSAPI");//交易类型
//非必填参数，商户可根据实际情况选填
//$unifiedOrder->setParameter("sub_mch_id","XXXX");//子商户号
//$unifiedOrder->setParameter("device_info","XXXX");//设备号
$unifiedOrder->setParameter("attach","$oid");//附加数据
//$unifiedOrder->setParameter("time_start","XXXX");//交易起始时间
//$unifiedOrder->setParameter("time_expire","XXXX");//交易结束时间
//$unifiedOrder->setParameter("goods_tag","$oid");//商品标记
//$unifiedOrder->setParameter("openid","XXXX");//用户标识
//$unifiedOrder->setParameter("product_id","XXXX");//商品ID
$prepay_id = $unifiedOrder->getPrepayId();
//=========步骤3：使用jsapi调起支付============
$jsApi->setPrepayId($prepay_id);
$jsApiParameters = $jsApi->getParameters();
echo ‘

第四步：调用；
