获取微信沙盒秘钥

@Test

param.put(“nonce_str”, nonce_str);//随机字符
String sign = WXPayUtil.generateSignature(param,“RemianInteractiveEntertainment88”, WXPayConstants.SignType.MD5);//通过SDK生成签名其中API_KEY为商户对应的真实密钥
param.put(“sign”, sign);
String xml = WXPayUtil.mapToXml(param);//将map转换为xml格式
String url = “https://api.mch.weixin.qq.com/sandboxnew/pay/getsignkey”;//沙箱密钥获取api
