微信支付 H5端和小程序端统一下单接口 4个JAVA源码文件代码

首先来看看官方支付文档的一些相关信息

1、用户在商户侧完成下单，使用微信支付进行支付

2、由商户后台向微信支付发起下单请求（调用统一下单接口）注：交易类型trade_type=MWEB

3、统一下单接口返回支付相关参数给商户后台，如支付跳转url（参数名“mweb_url”），商户通过mweb_url调起微信支付中间页

4、中间页进行H5权限的校验，安全性检查（此处常见错误请见下文）

5、如支付成功，商户后台会接收到微信侧的异步通知

6、用户在微信支付收银台完成支付或取消支付,返回商户页面（默认为返回支付发起页面）

7、商户在展示页面，引导用户主动发起支付结果的查询

8,9、商户后台判断是否接到收微信侧的支付结果通知，如没有，后台调用我们的订单查询接口确认订单状态

10、展示最终的订单支付结果给用户

常见问题

一、回调页面

正常流程用户支付完成后会返回至发起支付的页面，如需返回至指定页面，则可以在MWEB_URL后拼接上redirect_url参数，来指定回调页面。

如，您希望用户支付完成后跳转至https://www.wechatpay.com.cn，则可以做如下处理：

假设您通过统一下单接口获到的MWEB_URL= https://wx.tenpay.com/cgi-bin/mmpayweb-bin/checkmweb?prepay_id=wx20161110163838f231619da20804912345&package=1037687096

则拼接后的地址为MWEB_URL= https://wx.tenpay.com/cgi-bin/mmpayweb-bin/checkmweb?prepay_id=wx20161110163838f231619da20804912345&package=1037687096&redirect_url=https%3A%2F%2Fwww.wechatpay.com.cn

注意：

1.需对redirect_url进行urlencode处理

2.由于设置redirect_url后,回跳指定页面的操作可能发生在：1,微信支付中间页调起微信收银台后超过5秒 2,用户点击“取消支付“或支付完成后点“完成”按钮。因此无法保证页面回跳时，支付流程已结束，所以商户设置的redirect_url地址不能自动执行查单操作，应让用户去点击按钮触发查单操作。回跳页面展示效果可参考下图

二、其它常见错误

序号	错误描述	解决方法
1	网络环境未能通过安全验证，请稍后再试	1. 商户侧统一下单传的终端IP(spbill_create_ip)与用户实际调起支付时微信侧检测到的终端IP不一致导致的，这个问题一般是商户在统一下单时没有传递正确的终端IP到spbill_create_ip导致，详细可参见客户端ip获取指引 2. 统一下单与调起支付时的网络有变动，如统一下单时是WIFI网络，下单成功后切换成4G网络再调起支付，这样可能会引发我们的正常拦截，请保持网络环境一致的情况下重新发起支付流程
2	商家参数格式有误，请联系商家解决	1. 当前调起H5支付的referer为空导致，一般是因为直接访问页面调起H5支付，请按正常流程进行页面跳转后发起支付，或自行抓包确认referer值是否为空 2. 如果是APP里调起H5支付，需要在webview中手动设置referer，如( Map extraHeaders = new HashMap(); extraHeaders.put("Referer", "商户申请H5时提交的授权域名");//例如 http://www.baidu.com ))
3	商家存在未配置的参数，请联系商家解决	1，当前调起H5支付的域名（微信侧从referer中获取）与申请H5支付时提交的授权域名不一致，如需添加或修改授权域名，请登陆商户号对应的商户平台--"产品中心"--"开发配置"自行配置 2，如果设置了回跳地址redirect_url，请确认设置的回跳地址的域名与申请H5支付时提交的授权域名是否一致
4	支付请求已失效，请重新发起支付	统一下单返回的MWEB_URL生成后，有效期为5分钟，如超时请重新生成MWEB_URL后再发起支付
6	请在微信外打开订单，进行支付	H5支付不能直接在微信客户端内调起，请在外部浏览器调起
7	IOS：签名验证失败

4：WxPayConfig 微信支付请求的一些基本参数静态的实体类

package com.xinjue.util;
/** * @author tqf* @version 创建时间：2019-4-10 上午11:13:33 * 类说明    小程序微信支付的配置文件*/
public class WxPayConfig {//小程序appidpublic static final String appid = "";// 公众号IDpublic static final String GZH_appid = "";//微信支付的商户idpublic static final String mch_id = "";//微信支付的商户密钥public static final String key = "";//支付成功后的服务器回调url//public static final String notify_url = ""; //正式区public static final String notify_url = ""; //测试区//签名方式，固定值public static final String SIGNTYPE = "MD5";//交易类型，小程序支付的固定值为JSAPIpublic static final String TRADETYPE = "JSAPI";//交易类型 wap H5端public static final String GZH_TRADETYPE = "MWEB";//微信统一下单接口地址public static final String pay_url = "https://api.mch.weixin.qq.com/pay/unifiedorder";// H5端 场景信息   scene_infopublic static final String scene_info = "{\"h5_info\": {\"type\":\"WAP\",\"wap_url\": \"\",\"wap_name\": \"心觉咨询\"}}";
}

测试的话需要在商户的H5支付设置
