Map转xml

请求微信接口时将Map参数转化为xml

PaymentKit.toXml(Map<String, String> params)

xml转Map

将微信接口响应的结果xml转化为Map

PaymentKit.xmlToMap(xml);

获取IP

IpKit.getRealIp(HttpServletRequest request);

创建签名

PaymentKit.createSign(Map<String, String> params, String partnerKey);

params为加密的参数,partnerKey为商户平台设置的API密钥key

key设置路径：微信商户平台(pay.weixin.qq.com)-->账户设置-->API安全-->密钥设置

统一下单

统一下单接口官方文档

WxPayApi.pushOrder(boolean isSandbox, Map<String, String> params);

代码示例参考具体支付方式中的代码

预付订单再次签名

公众号/小程序支付

公众号支付二次签名-微信内H5调起支付
小程序支付二次签名-小程序调起支付API

PaymentKit.prepayIdCreateSign(String prepay_id)

    /**
     * 预付订单再次签名
     * @param prepay_id
     * @return <Map<String, String>>
     */
    public static Map<String, String> prepayIdCreateSign(String prepay_id) {
        Map<String, String> packageParams = new HashMap<String, String>();
        packageParams.put("appId", WxPayApiConfigKit.getWxPayApiConfig().getAppId());
        packageParams.put("timeStamp", String.valueOf(System.currentTimeMillis() / 1000));
        packageParams.put("nonceStr", String.valueOf(System.currentTimeMillis()));
        packageParams.put("package", "prepay_id=" + prepay_id);
        packageParams.put("signType", "MD5");
        String packageSign = PaymentKit.createSign(packageParams, WxPayApiConfigKit.getWxPayApiConfig().getPaternerKey());
        packageParams.put("paySign", packageSign);
        return packageParams;
    }

APP支付

APP支付二次签名-调起支付

    /**
     * 预付订单再次签名
     * @param prepay_id
     * @return <Map<String, String>>
     */
    public static Map<String, String> prepayIdCreateSignByApp(String prepay_id) {
        Map<String, String> packageParams = new HashMap<String, String>();
        packageParams.put("appid", WxPayApiConfigKit.getWxPayApiConfig().getAppId());
        packageParams.put("partnerid", WxPayApiConfigKit.getWxPayApiConfig().getMchId());
        packageParams.put("prepayid", prepay_id);
        packageParams.put("package", "Sign=WXPay");
        packageParams.put("noncestr", System.currentTimeMillis() + "");
        packageParams.put("timestamp", System.currentTimeMillis() / 1000 + "");
        String packageSign = PaymentKit.createSign(packageParams, WxPayApiConfigKit.getWxPayApiConfig().getPaternerKey());
        packageParams.put("sign", packageSign);
        return packageParams;
    }

异步通知验证签名

PaymentKit.verifyNotify(Map<String, String> params, String paternerKey)

params为回调的xml转Map参数,partnerKey为商户平台设置的API密钥key

key设置路径：微信商户平台(pay.weixin.qq.com)-->账户设置-->API安全-->密钥设置
