PHP微信支付实例解析
本文为大家分享了PHP微信支付实例,包括PHP微信支付源码,PHP微信退款源码,php微信支付接口,供大家参考,具体内容如下
1.JSapi支付demo(在微信客户端中点击)
/**
* JS_API支付demo
* ====================================================
* 在微信浏览器里面打开H5网页中执行JS调起支付。接口输入输出数据格式为JSON。
* 成功调起支付需要三个步骤:
* 步骤1:网页授权获取用户openid
* 步骤2:使用统一支付接口,获取prepay_id
* 步骤3:使用jsapi调起支付
*/

//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);
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
¥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

2.native支付模式一demo(用微信扫的静态链接二维码)
/**

* 会将productid和用户openid发送到商户设置的链接上,商户收到
* 请求生成订单,调用统一支付接口下单提交到微信,微信会返回
* 给商户prepayid。
* 本例程对应的二维码由native_call_qrcode.php生成;
* 本例程对应的响应服务为native_call.php;
* 需要两者配合使用。
