求大神们看一下chooseWXPay:fail

授权目录
http://xxxxxx/semp_web/
支付页面
http://xxxxxx/semp_web/weixinSaleAction!gotoPay.action

SortedMap parameters = new TreeMap();

parameters.put("appid", appid);

parameters.put("mch_id", mchid);

parameters.put("nonce_str", nonceStr);
parameters.put("body", "test");
parameters.put("out_trade_no", "20160320001");
parameters.put("total_fee", 1);
parameters.put("spbill_create_ip", WeixinUtil.localIp());
parameters.put("notify_url", "http://xxxxxx/semp_web/distribution/commodityBuyAction!payback.action");
parameters.put("trade_type", "JSAPI");
parameters.put("openid", openid);
String characterEncoding = "UTF-8";
String sign = WeixinUtil.createSign(characterEncoding, parameters).toUpperCase();
parameters.put("sign", sign);
String url = "https://api.mch.weixin.qq.com/pay/unifiedorder";
String xmlData = WeixinUtil.map2xmlBody(parameters, "xml");
com.alibaba.fastjson.JSONObject jsonObj = WeixinUtil.httpRequest(url, "POST", xmlData, 2);
得到预支付prepay_id
SortedMap signParameters = new TreeMap();
signParameters.put("appId", appid);
signParameters.put("timeStamp", timeStamp);
signParameters.put("nonceStr", nonceStr);
String prepayId = "prepay_id="+jsonObj.getString("prepay_id");
signParameters.put("package", prepayId);
signParameters.put("signType", "MD5");
String signFinal = WeixinUtil.createSign(characterEncoding, signParameters).toUpperCase();
得到最终签名

wx.chooseWXPay({
timestamp: result.timeStamp,
nonceStr: result.nonce_str,
package: result.package,
signType: 'MD5',
paySign: result.paySign, // 支付签名
success: function (res) {
alert(res);
}
});
