1.拼单

AlixPayOrder *order = [[AlixPayOrder alloc]init];

        order.partner = [params objectAtIndex:1];

        order.seller = [params objectAtIndex:2];

        order.tradeNO = resultDict[@"ordersn"];

        order.productName = [params objectAtIndex:6];

        order.productDescription = [params objectAtIndex:8];

        order.amount = [NSString stringWithFormat:@"%.2f", [(NSString *)((NSDictionary *)resultDict[@"paychannel"])[@"amount"]floatValue] / 100];

        order.notifyURL = [(NSString *)[params objectAtIndex:3] stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

        order.paymentType = [params objectAtIndex:7];

        order.itBPay = [NSString stringWithFormat:@"%@m", [params objectAtIndex:9]];

        NSString *orderInfo = [order description];

        id<DataSigner> signer;

        signer = CreateRSADataSigner([params objectAtIndex:0]);

        NSString *signedStr = [signer signString:orderInfo];//gw 订单信息用私钥签名

        //        NSNewcoLog(@"%@", signedStr);

        NSString *orderString = [NSString stringWithFormat:@"%@&sign="%@"&sign_type="%@"",

                                 orderInfo, signedStr, [params objectAtIndex:5]];

        NSString *appScheme = @"Lottery-Trade-3-3";

        ApplicationDelegate.key = [(NSArray *)((NSDictionary *)resultDict[@"paychannel"])[@"payparams"]objectAtIndex:4];//签约帐户后获取到的支付宝公钥

2.调用支付宝反馈

 

[[AlipaySDK defaultService] payOrder:orderString fromScheme:appScheme callback:^(NSDictionary *resultDic) {

 

            NSLog(@"支付宝返回：%@",resultDic);

 

            if (resultDic) {

 

                //结果处理

 

                NsZhifubaoModel *result = [NsZhifubaoModel zhifuWithDictionary:resultDic];

 

                if ([result.resultStatus integerValue] == 9000) {

 

                    if ([result.success isEqualToString:@"true"]) {

 

                        NsAccountRecordController *accountCtrl = [[NsAccountRecordController alloc]initWithTitle:@"账户明细"  type:AccountRecord_Normal];

 

                        accountCtrl.isWarn = result.out_trade_no;

 

                        UINavigationController *nav = [ApplicationDelegate navigationController];

 

                        [nav pushViewController:accountCtrl animated:YES];

 

                        [accountCtrl release];

 

                    }

 

                    /*

 

                    //签名

 

                    NSString* key = [(NSArray *)((NSDictionary *)resultDict[@"paychannel"])[@"payparams"]objectAtIndex:4];//签约帐户后获取到的支付宝公钥

 

                    id<DataVerifier> verifier;

 

                    verifier = CreateRSADataVerifier(key);

 

                    if ([verifier verifyString:result.resultString withSign:result.sign])

 

                    {

 

                        //验证签名成功，交易结果无篡改

 

                        NsAccountRecordController *accountCtrl = [[NsAccountRecordController alloc]initWithTitle:@"账户明细"  type:AccountRecord_Normal];

 

                        accountCtrl.isWarn = result.out_trade_no;

 

                        UINavigationController *nav = [ApplicationDelegate navigationController];

 

                        [nav pushViewController:accountCtrl animated:YES];

 

                        [accountCtrl release];

 

                    }

 

                    */

 

                }

 

                else {

 

                    NSLog(@"交易失败");

 

                }

 

            } else {

 

                NSLog(@"交易失败");

 

            }

 

        }];

 

 3.调用支付宝钱包

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {

    if ([url.host isEqualToString:@"safepay"]) {

        //跳转支付宝钱包进行支付，处理支付结果

        [[AlipaySDK defaultService] processOrderWithPaymentResult:url standbyCallback:^(NSDictionary *resultDic) {

            NSLog(@"支付宝返回：%@",resultDic);

            if (resultDic) {

                //结果处理

                NsZhifubaoModel *result = [NsZhifubaoModel zhifuWithDictionary:resultDic];

                if ([result.resultStatus integerValue] == 9000) {

                    if ([result.success isEqualToString:@"true"]) {

                        //验证签名成功，交易结果无篡改

                        id<DataVerifier> verifier;

                        verifier = CreateRSADataVerifier(key);

                        // 验证的步骤：首先把订单信息和签名值分别提取出来

                        // 订单信息就是sign_type的连字符&之前的所有字符串result.resultString

                        // 签名值是sign后面双引号内的内容，注意签名的结尾也是=  result.sign

                        if ([verifier verifyString:result.resultString withSign:result.sign]) {//gw 在处理返回的支付结果时，需要使用公钥验证返回结果是否被篡改了

                            NsAccountRecordController *accountCtrl = [[NsAccountRecordController alloc]initWithTitle:@"账户明细"  type:AccountRecord_Normal];

                            accountCtrl.isWarn = result.out_trade_no;

                            UINavigationController *nav = [ApplicationDelegate navigationController];

                            [nav pushViewController:accountCtrl animated:YES];

                            [accountCtrl release];

                        }

                    }

            }

                else {

                    NSLog(@"交易失败");

                }

            } else {

                NSLog(@"交易失败");

            }

 

        }];

    }

    if ([url.host isEqualToString:@"platformapi"]) {

        [[AlipaySDK defaultService] processAuthResult:url standbyCallback:^(NSDictionary *resultDic) {

            NSLog(@"支付宝返回：%@",resultDic);

        }];

    }

    return YES;

}

 附加：支付宝反回字符串的解析（将字符串分割成子串，并且以字典的形式存储）
