微信支付与支付宝支付

之前做过娃娃机的项目，因为直接对接微信和支付宝利率稍微高了一些，所以公司决定直接走银行：微信和支付宝调用银行的接口来完成支付

支付宝支付流程：

注册个人或者企业账号然后接入开发平台--->h5接入-->查看开发文档

当时我们做的是扫描设备二维码跳转授权登陆页面然后获取用户信息后进行充值和其他操作的：

需要导入的maven配置文件：

<dependency>
   <groupId>com.aliyun</groupId>
   <artifactId>aliyun-java-sdk-core</artifactId>
   <version>3.3.1</version>
</dependency>
<dependency>
   <groupId>com.aliyun</groupId>
   <artifactId>aliyun-java-sdk-dysmsapi</artifactId>
   <version>1.0.0</version>
</dependency>
这个是要看文档的哈，我们是通过扫支付宝账号跳转页面的所以是属于h5的，
判断是微信支付还是支付宝支付：然后将设备id带过去

@RequestMapping("/Landing")
   public String Landing(HttpServletRequest req, HttpServletResponse response, HttpSession session) {

      try {
         String userAgent = req.getHeader("user-agent");
         // 支付宝
         if (userAgent != null && userAgent.contains("AlipayClient")) {
//       String equid = req.getParameter("equipmentid");
            session.setAttribute("sel_equipmentid", equid);

            return this.aliPayEmpower();

            // 微信
         } else if (userAgent != null && userAgent.contains("MicroMessenger")) {
            String APPID = Constant.APPID;
            String url = "https://open.weixin.qq.com/connect/oauth2/authorize?appid=" + APPID + "&redirect_uri=" + "http://www.dm168.cn/start_equip" + "&response_type=code&scope=snsapi_userinfo&state=123#wechat_redirect";
            String equid = req.getParameter("equipmentid");
            session.setAttribute("sel_equipmentid", equid);
            return "redirect:" + url;
            // 其他
         } else {
            return "";
         }

      } catch (Exception e) {
         System.out.println(e);
         return "";
      }

   }

//支付宝授权登陆：

//支付宝是根据银行返回的订单号来吊起支付接口的，微信支付时时根据银行返回的

微信根据返回的信息吊起微信jsapi
