付款码支付 WxPayMicropayRequest 中的签名,怎么弄的?

[raymondZhong]

How do I get a payment code to pay a signature in WxPayMicropayRequest?

Version 4.8.0

String nonceStr = IdUtil.fastSimpleUUID();

WxPayMicropayRequest request = new WxPayMicropayRequest();
request.setAppid(wxPayService.getConfig().getAppId());
request.setMchId(wxPayService.getConfig().getMchId());
request.setNonceStr(nonceStr);
request.setBody(body);
request.setOutTradeNo(outTradeNo);
request.setTotalFee(totalFee);
request.setSpbillCreateIp(ip);
request.setAuthCode(authCode);


HashMap<String,String> map = new HashMap<>();
map.put("appid",wxPayService.getConfig().getAppId());
map.put("mch_id",wxPayService.getConfig().getMchId());
map.put("nonce_str",nonceStr);
map.put("body",body);
map.put("out_trade_no",outTradeNo);
map.put("total_fee",totalFee.toString());
map.put("spbill_create_ip",ip);
map.put("auth_code",authCode);

String[] ignoredParams = new String[]{};
String sign = SignUtils.createSign(map, "", apiV2Key, ignoredParams);

request.setSign(sign); 

WxPayMicropayResult micropayResult = wxPayService.micropay(request);

----报错-----

返回代码：[FAIL]，返回信息：[签名错误，请检查后再试]，微信返回的原始报文：
<return_code></return_code>
<return_msg></return_msg>
