微信支付

流程 :
移動端向后臺發送購物請求 -> 后臺發送相應信息發給微信 -> 微信生成訂單反饋給后臺 -> 后臺反饋訂單信息給移動端 -> 移動端用相應信息調用手機微信客戶端 -> 完成支付收到相應反饋再給后臺發送完成信息備案存儲

移動端工作

1.下載微信支付SDK

2.在工程General中添加添加相應靜態庫

3.在Info中添加 微信開發者ID

4.appDelegate中程序已啟動注冊微信支付

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

    [WXApi registerApp:@"wxb4ba3c02aa476ea1" withDescription:@"com.kdx.touchfound"];

    return YES;
}```
5.發送用戶選擇貨品給后臺,獲取后臺回饋的訂單信息,填充后調用微信客戶端

        NSMutableString *retcode = [dict objectForKey:@"retcode"];
        if (retcode.intValue == 0){
            NSMutableString *stamp = [dict objectForKey:@"timestamp"];
            
            //調起微信支付
            PayReq* req = [[PayReq alloc] init];
            req.partnerId = [dict objectForKey:@"partnerid"];
            req.prepayId = [dict objectForKey:@"prepayid"];
            req.nonceStr = [dict objectForKey:@"noncestr"];
            req.timeStamp = stamp.intValue;
            req.package = [dict objectForKey:@"package"];
            req.sign = [dict objectForKey:@"sign"];
            [WXApi sendReq:req];
            //日志輸出
            NSLog(@"appid=%@\npartid=%@\nprepayid=%@\nnoncestr=%@\ntimestamp=%ld\npackage=%@\nsign=%@",[dict objectForKey:@"appid"],req.partnerId,req.prepayId,req.nonceStr,(long)req.timeStamp,req.package,req.sign );
        }

6.接收支付結果
在AppDelegate中遵守協議  <WXApiDelegate>

//用于接收支付結果

• (void)onResp:(BaseResp *)resp {
  if ([resp isKindOfClass:[PayResp class]]) {
  NSString stringMsg,strTitle = @"支付結果";
  switch (resp.errCode) {
  case WXSuccess:
  stringMsg = @"支付結果 : 成功";
  NSLog(@"支付成功 - retcode = %d",resp.errCode);
  break;

        default:
            stringMsg = @"支付結果 : 失敗";
            NSLog(@"支付成功 - retcode = %d",resp.errCode);
            break;
    } 
  

  }
  }
  //用于應用間跳轉

• (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<NSString *,id> *)options {
  return [WXApi handleOpenURL:url delegate:self];
  }
