微信支付 jsApi 微信浏览器内支付

1. 调起微信支付的域名要和微信支付配置的一致,导致无法本地测试

解决方案： 修改本地host文件将配置的域名指向本机, 手机wifi使用本机代理上网。

IJPay-All文档地址

1. maven中引入开发包

<dependency><groupId>com.github.javen205</groupId><artifactId>IJPay-WxPay</artifactId><version>2.4.0</version></dependency>

2. 创建请求需要的参数类。配置信息在application中

import lombok.Data;import org.springframework.beans.factory.annotation.Value;import org.springframework.context.annotation.Configuration;@Data@Configurationpublic class WxPayProperties {/*** 设置微信公众号或者小程序，h5等的appid.*/@Value("${wx.pay.appId}")private String appId;/*** 微信支付商户号.*/@Value("${wx.pay.mchId}")private String mchId;/*** 微信支付商户密钥.*/@Value("${wx.pay.mchKey}")private String mchKey;/*** 异步回调地址*/@Value("${wx.pay.notifyUrl}")private String notifyUrl;}

application配置文件 如下

wx:pay:appId: wx123223342341 # appidmchId: 123423123 # 商户号mchKey: U6gG1CqAqwedrfgfffrvfXFBokr # 秘钥 微信商户平台(pay.)-->账户设置-->API安全-->密钥设置notifyUrl: :35084/wx/wxPayNotice #可以被外网访问的接口

3. 封装JsApi支付工具

package com.jyl.shop.config.wx;/*** 开发公司：个人* 版权：个人* <p>* JsApiOrderModel** @author 刘志强* @created Create Time: /12/21*/import com.ijpay.core.model.BaseModel;public class JsApiOrderModel extends

3. 请求示例

public Map<String,Object> wxJsApiPay(ShopOrders shopOrders) {ShopMember shopMember = shopMemberService.getMember();String ip = getIpAddr();Map<String, String> params = JsApiOrderModel.builder().appid(wxPayProperties.getAppId()).mch_id(wxPayProperties.getMchId()).nonce_str(shopOrders.getOrderNo()) // 订单描述.body("微信支付") .out_trade_no(shopOrders.getOrderNo()) // 订单号.total_fee(String.valueOf((shopOrders.getRealTotalMoney().multiply(new BigDecimal("100"))).intValue())) // 支付金额.spbill_create_ip(ip).notify_url(wxPayProperties.getNotifyUrl()).trade_type(TradeType.JSAPI.getTradeType()).openid("99999999999").build().createSign(wxPayProperties.getMchKey(), SignType.MD5);String xmlResult = WxPayApi.pushOrder(false, params);Map<String, String> resultMap = WxPayKit.xmlToMap(xmlResult);if (StringUtils.equals(resultMap.get("return_code"), "SUCCESS")) {String prepayId = resultMap.get("prepay_id");Map<String, String> packageParams = WxPayKit.prepayIdCreateSign(prepayId, wxPayProperties.getAppId(),wxPayProperties.getMchKey(), SignType.MD5);// 微信浏览器中拿此参数调起支付return packageParams;}return null;}

获取客户端IP地址

private String getIpAddr() {String ip = request.getHeader("x-forwarded-for");if (ip != null && ip.length() != 0 && !"unknown".equalsIgnoreCase(ip)) {// 多次反向代理后会有多个ip值，第一个ip才是真实ipif (ip.indexOf(",") != -1) {ip = ip.split(",")[0];}}if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {ip = request.getHeader("Proxy-Client-IP");}if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {ip = request.getHeader("WL-Proxy-Client-IP");}if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {ip = request.getHeader("HTTP_CLIENT_IP");}if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {ip = request.getHeader("HTTP_X_FORWARDED_FOR");}if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {ip = request.getHeader("X-Real-IP");}if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {ip = request.getRemoteAddr();}return ip != null ? ip : "192.168.0.1";}

异步通知

@PostMapping("/notifyUrl")public void notifyUrl(@RequestBody String xmlData) {Map<String, String> resultMap = WxPayKit.xmlToMap(xmlData);// 平台订单号String platformOrderNumber = resultMap.get("out_trade_no");// 实际支付金额BigDecimal paymentAmount = new BigDecimal(resultMap.get("cash_fee"));// 微信订单号String transactionId = resultMap.get("transaction_id");// 支付完成时间String timeEnd = resultMap.get("timeEnd");....}
