支付验证签名失败问题描述： 统一下单可以正常得到prepay_id，调用wx:requestPayment 提示支付验证签名失败。 小程序端代码： wx.requestPayment({
timeStamp: pay_p['timeStamp'],
nonceStr: pay_p['nonceStr'],
package: pay_p['package'],
signType: pay_p['signType'],
paySign: pay_p['paySign'],
success (res) {
console.log(res)
},
fail (res) {
console.log(res)
}
})
pay_p是后端Java生成的，java代码： @RequestMapping("/payBefore")
public Map payBefore (@RequestBody Map requestData) throws Exception
{
logger.info("WxController payBefore requestData={}",gson.toJson(requestData));
Map result = new HashMap<>();
Integer time = MyUtil.getCurrentTimestamp();
result.put("timeStamp",time.toString());
result.put("nonceStr",WXPayUtil.generateNonceStr());
result.put("package",requestData.get("package"));
result.put("signType",WXPayConstants.SignType.MD5.toString());
result.put("appId",DefaultConsts.WX_APPID);
WxConfig config = new WxConfig();
String sign = WXPayUtil.generateSignature(result, config.getKey(), WXPayConstants.SignType.MD5);
result.put("paySign",sign);
logger.info("WxController payBefore result={}",gson.toJson(result));
return result;
}
WXPayUtil、WXPayConstantssh jdk中代码
已经换过key了，还是没通过。
