微信支付
微信支付的兩種模式
1:由微信生成二維碼,客戶掃描二維碼後,確認支付,微信回調給當前系統.
2:由系統調用統一下單API,取得預支付交易信息後,根據信息生成二維碼,然後後臺循環查詢訂單API接口查詢付款狀態(統一下單API,查詢訂單API)
區別:模式一是跳到微信讓微信給我們生成二維碼
模式二是可控制高,比較自主.
一:二維碼
1.1:二維碼優勢
♦ 信息量大,可以容納1850個大寫字母或者2710個數字或500多個漢字
♦ 應用範圍廣,支持文字,聲音(存放地址,地址裏播放聲音其實還是地址),圖片,指紋等等
♦ 容錯能力強,即是圖片出現部分的破損也能使用
♦ 成本低,容易製作
二:微信支付
2.1:一共12個API
實現思路:
微信接口只接收xml字符串需要sas解析或者dom4j解析.將map轉成xml通過httpClient遠程提交參數接收返回結果
微信接口提供了一些工具類把map轉換成xml
統一下單接口最終就是通過它生成一串支付地址,然後把支付地址展示給前端頁面,讓用戶支付.最終訂單有沒有完成,需要調用查詢訂單接口,查看完成狀態.
微信支付發送的是post請求,請求是xml格式的
代碼實現
一:需要創建支付服務模塊(pyg_pay_interface和pyg_pay_service)
**A?*pyg_pay_service
1:pom.xml文件導入座標
//打包方式爲war包爲web項目
<packaging>war</packaging>

4.在pyg_common導入配置文件
支付相關的信息
appid=wx8397f8696b538317 //商戶ID
partner=1473426802 //商戶號
partnerkey=T6m9iK73b0kn9g5v426MKfHQH7X8rKwb //商戶的key值
notifyurl=http://a31ef7db.ngrok.io/WeChatPay/WeChatPayNotify //回調地址,我們的二維碼使我們自己生成的所以不需要回調
導入HttpClientUtils.java工具類

5.根據Dubbo服務掃描的包創建包(com.pinyougou.pay.service.impl)
♦ 5.1:pyg_pay_interface模塊下創建PayService.java接口
public interface PayService{
//請求完微信生成支付地址的方法(二維碼)
//參數1:商戶訂單號 參數二:總金額
public Map createNative(String out_trade_no,String total_fee);
//請求微信查詢支付狀態
public Map queryPayStatus(String out_trade_no);
//根據用戶id獲取支付單對象
public TbPayLog searchPayLogFromRedis(String userId);
//根據支付單號,更新付款信息
public void updateOrderStatus(String out_trade_no,String transaction_id);
}
♦ 5.2:pyg_pay_service模塊com.pinyougou.pay.service.impl路徑下創建PayServiceImpl.java實現類
@Service
public class PayServiceImpl implement PayService{
//拿到配置文件的屬性
@Value("${appid}")
private String appid;//商戶ID
@Value("${partner}")
private String partner;//商家號
@Value("${partnerkey}")
private String partnerkey;//祕鑰
@Value("${notifyurl}")
private String notifyurl;//回調地址(必填,內容隨便)
@Autowride
private RedisTemplate redisTemplate;
@Autowride
private TbPayLogMapper payLogMapper;
@Autowride
private TborderMapper orderMapper;
@Override
public Map createNative(String out_trade_no,String total_fee){
try{//請求微信的生成訂單接口地址,獲取支付的連接地址
HttpClientUtils util=new HttpClientUtils("https://api.mch.weixin.qq.com/pay/unifiedorder");
//請求內容數據的封裝
Map map= new HashMap<>();
map.put("appid",appid);
map.put("mch_id",partner);
map.put("nonce_str",WXPayUtil.generateUUID());//隨機32位字符串
map.put("body","品優購商品"); //描述信息
map.put("out_trade_no",out_trade_no);//商戶訂單號
double totalMoney=new Double(total_fee)*100;
map.put("total_fee",(long)totalMoney+"") //商品總金額單位爲分
map.put("spbill_create_ip","127.0.0.1"); //終端地址
map.put("notify_url",notifyurl); //通知地址
map.put("trade_type","NATIVE"); //交易類型
//通過微信的api將map轉成xml格式的字符串
//生成帶簽名的xml
String signedXml= WXPayUtil.generateSignedXml(map,partnerkey);
Sytem.out.print("發送給微信"+signedXml)
//設置請求參數setXmlParam();方法發送的是xml格式
util.setXmlParam(signedXml);
//發送post請求,發送的是xml格式的
util.post();
String content=util.getContent();
Sytem.out.print("微信返回的"+content)
//通過工具類將返回的String的xml內容轉換成map
Map responseMap=WXPayUtil.xmlToMap(content);
Map resultMap=new HashMap<>();
resultMap.put("out_trade_no",out_trade_no); //支付單號
resultMap.put("total_fee",total_fee); //支付金額
resultMap.put("code_url",responseMap.get("code_url"));//支付地址
return resultMap;
}catch(IOException e){
e.printStackTrace();
}
return null;
}
}
@Override
public Map queryPayStatus(String out_trade_no){
try{
//1.請求微信的訂單狀態查詢接口
HttpClient util new HttpClient("https://api.mch.weixin.qq.com/pay/orderquery");
//2.封裝數據
Map requestMap= new HashMap<>();
requestMap.put("appid",appid);
requestMap.put("mch_id",mch_id);
requestMap.put("out_trade_no",out_trade_no);
requestMap.put("nonce_str",WXPayUtil.generateUUID());
//3.轉換帶簽名的數據
String signedXml=WXPayUtil.generateSignedXml(requestMap,partnerkey);
//4.設置到xml格式到post請求中
util.setXmlParam(signedXml);
//5.發送請求(xml)
util.post();
//6.獲取返回值
String content= util.getContent();
Map resultMap= WXPayUtil.xmlToMap(content);
return resultMap;
}catch(Exception e){
e.printStackTrace();
return null;
}
}
@Override
public TbPayLog searchPayLogFromRedis(String userId){
TbPayLog payLog=(TbPayLog) redisTemplate.boundHashOps("payLog").get(userId);
return payLog;
}
@Override
//根據支付單號,更新付款信息
public void updateOrderStatus(String out_trade_no,String transaction_id){
//獲取支付單對象
TbPayLog payLog= payLogMapper.selectByPrimaryKey(out_trade_no);
//獲取支付狀態,微信的業務代碼
payLog.setTransactionId(transaction_id);
//支付時間
payLog.setPayTime(new Date());
//支付狀態
payLog.setTradeState("1");//0未支付 1已支付
//更新數據庫中的payLog數據
payLogMapper.updateByPrimaryKey(payLog);
//根據支付單的訂單列表,更新訂單支付的相關信息
String[] orderIds=payLog.getOrdrList().split(",");
for(String orderId :orderIds){
TbOrder order= orderMapper.selectByPrimaryKey(Long.parseLong(orderId);
//狀態:1 未付款 2 已付款
order.setStatus("2");
order.setPaymentTime(new Date());
order.setUpdateTime(new Date());
orderMapper.updateByPrimaryKey(order);
}
//將redis中的當前用戶的付款信息清除
redisTemplate.boundHash("payLog").delete(payLog.getUserId());
}
6.創建PayController.java類
@RestController
@RequestMapping("/pay")
public class PayController{
@Reference
private PayService payService;
@RequestMapping("/createNative")
public Map createNative(String out_trade_no,String total_fee){
/* String outTradeNo=UUID.randomUUID().toString().replaceAll("_","");*/
//獲取用戶的支付單
String userId=SecurityContextHolder.getContext().getAuthentication().getName();
//從Redis中獲取用戶的支付單
TbPayLog payLog= payService.searchPayLogFromRedis(userId);
//設置訂單號 付款金額
return payService.createNative(payLog.getOutTradeNo(),payLog.getTotalFee());
}
@RequestMapping("/queryPayStatus")
public Result queryPayStatus(String out_trade_no){
int timeout=1;
//無限循環查詢訂單支付狀態
while(true){
Map resultMap=payService.queryPayStatus(out_trade_no);
//失敗的邏輯
if(resultMap==null){
return new Result(false,"付款失敗!!!")；
}
//支付成功的邏輯
if("SUCCESS".equals(resultMap.get("trade_state"))){
//修改order的狀態 修改paylog的狀態
payService.updateOrderStatus(out_trade_no,resultMap.get("transaction_id").toString());
return new Result(true,"付款成功!!!")；
}
//每隔三秒查詢訂單的支付狀態
try{
Thread.sleep(3000);
}catch(Exception e){
}
timeout++;
//退出邏輯 ,超過該時間,停止支付查詢
if(timeout>10){
return new Result(false,"timeout");
}
}
}
}
