怎么用java调用微信支付接口java调用微信支付接口方法:
RequestHandler requestHandler = new RequestHandler(super.getRequest(),super.getResponse());
//获取token //两小时内有效,两小时后重新获取
Token = requestHandler.GetToken();
//更新token 到应用中
requestHandler.getTokenReal();
System.out.println("微信支付获取token=======================:"Token);
//requestHandler 初始化
requestHandler.init();
requestHandler.init(appid,appsecret, appkey,partnerkey, key);
// --------------------------------本地系统生成订单-------------------------------------
// 设置package订单参数
SortedMapString, String packageParams = new TreeMapString, String();
packageParams.put("bank_type", "WX"); // 支付类型
packageParams.put("body", "xxxx"); // 商品描述
packageParams.put("fee_type", "1"); // 银行币种
packageParams.put("input_charset", "UTF-8"); // 字符集
packageParams.put("notify_url", ""); // 通知地址这里的通知地址使用外网地址测试,注意80端口是否打开 。
packageParams.put("out_trade_no", no); // 商户订单号
packageParams.put("partner", partenerid); // 设置商户号
packageParams.put("spbill_create_ip", super.getRequest().getRemoteHost()); // 订单生成的机器IP , 指用户浏览器端IP

//生成预付快订单完成,返回给android,ios 掉起微信所需要的参数 。

====================到此为止,预付款订单已生成 , 并且已返回客户端====================

java支付功能已经写好了,怎么写用户前三次购买是免费记录一下用户购买商品的次数呗java支付代码书写 , 或者查一下userAndGoods的对应关系java支付代码书写 , 看他同一件商品买了几次不就完了?只要次数不大于3,下单的金额就是0
java支付代码书写的介绍就聊到这里吧,感谢你花时间阅读本站内容,更多关于支付宝支付java代码、java支付代码书写的信息别忘了在本站进行查找喔 。
