支付宝支付

    按照“支付宝开放平台”的“iOS集成流程”进行集成:
    https://docs.open.alipay.com/204/105295/

    一、项目配置:

    • 请按照上面给的链接文档进行配置

    二、代码:

    1.在.pch文件中宏定义跳转app的URLSchemes:

    //跳转本app需要用的 URLScheme
    #define kAppURLScheme @"AJProject"
    

    2.在用到支付宝支付的地方,倒入头文件:

    #import <AlipaySDK/AlipaySDK.h>
    

    3.AJGoodsCashierController.m文件(收银台页):

    #pragma mark - 支付宝相关
    /**
     支付宝支付
    
     @param orderStr 后台返回的订单string
     */
    -(void)aliPayWithOrderStr:(NSString *)orderStr {
        [AlipaySDK.defaultService payOrder:orderStr fromScheme:kAppURLScheme callback:^(NSDictionary *resultDic) {
            //这是从支付宝H5页面支付之后走的回调 - 未离开了本app
            [self postAliPayResultNotificationWithDict:resultDic];
        }];
    }
    /**发送支付宝支付结果的通知*/
    -(void)postAliPayResultNotificationWithDict:(NSDictionary *)dict {
        if (dict != nil) {
            [NSNotificationCenter.defaultCenter postNotificationName:@"kAliPayResultNotification" object:nil userInfo:dict];
        }
    }
    /**接收到通知的回调 - “支付宝支付结果”*/
    -(void)getAlipayOrderPayResult:(NSNotification *)notification {
        if (notification.userInfo != nil) {
            NSDictionary * resultDic = notification.userInfo;
            NSString * resultStatus = [resultDic valueForKey:@"resultStatus"];
            if ([resultStatus isEqualToString:@"9000"]) {//支付成功
                self.payResultLabel.text = @"支付成功!";
                [self.payResultImageView setImageWithName:@"icon_pay_paySuccess"];
            } else {//支付失败
                self.payResultLabel.text = @"支付失败...";
                [self.payResultImageView setImageWithName:@"icon_pay_payFail"];
            }
            self.payResultBgView.hidden = false;
            [self.view bringSubviewToFront:self.payResultBgView];
        }
    }
    

    4.AppDelegate.m文件:

    • 下面的 processAuthResult 方法,是处理“支付宝app授权结果信息”的方法,如果需求中有对授权结果的处理,可以选择调用。如果只是处理“支付成功/失败的结果信息”,那么只需要调用 processOrderWithPaymentResult 方法即可。
    #pragma mark - 支付宝接入
    // NOTE: 9.0以前
    - (BOOL)application:(UIApplication *)application
                openURL:(NSURL *)url
      sourceApplication:(NSString *)sourceApplication
             annotation:(id)annotation
    {
        if ([url.host isEqualToString:@"safepay"]) {
            
            // 支付跳转支付宝钱包进行支付,处理支付结果(从支付宝app支付之后走的回调 - 离开了本app)
            [[AlipaySDK defaultService] processOrderWithPaymentResult:url standbyCallback:^(NSDictionary *resultDic) {
                NSLog(@"result = %@",resultDic);
                [self postAliPayResultNotificationWithDict:resultDic];
            }];
            
            //处理授权结果
            [[AlipaySDK defaultService] processAuthResult:url standbyCallback:^(NSDictionary *resultDic) {
                NSLog(@"result = %@",resultDic);
                // 解析 auth code
                NSString *result = resultDic[@"result"];
                NSString *authCode = nil;
                if (result.length>0) {
                    NSArray *resultArr = [result componentsSeparatedByString:@"&"];
                    for (NSString *subResult in resultArr) {
                        if (subResult.length > 10 && [subResult hasPrefix:@"auth_code="]) {
                            authCode = [subResult substringFromIndex:10];
                            break;
                        }
                    }
                }
                NSLog(@"授权结果 authCode = %@", authCode?:@"");
            }];
            
        }
        return YES;
    }
    // NOTE: 9.0及以后,使用新API接口
    - (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<NSString*, id> *)options
    {
        if ([url.host isEqualToString:@"safepay"]) {
            
            // 支付跳转支付宝钱包进行支付,处理支付结果(从支付宝app支付之后走的回调 - 离开了本app)
            [[AlipaySDK defaultService] processOrderWithPaymentResult:url standbyCallback:^(NSDictionary *resultDic) {
                NSLog(@"result = %@",resultDic);
                [self postAliPayResultNotificationWithDict:resultDic];
            }];
            
            // 处理授权结果
            [[AlipaySDK defaultService] processAuthResult:url standbyCallback:^(NSDictionary *resultDic) {
                NSLog(@"result = %@",resultDic);
                // 解析 auth code
                NSString *result = resultDic[@"result"];
                NSString *authCode = nil;
                if (result.length>0) {
                    NSArray *resultArr = [result componentsSeparatedByString:@"&"];
                    for (NSString *subResult in resultArr) {
                        if (subResult.length > 10 && [subResult hasPrefix:@"auth_code="]) {
                            authCode = [subResult substringFromIndex:10];
                            break;
                        }
                    }
                }
                NSLog(@"授权结果 authCode = %@", authCode?:@"");
            }];
        
        }
        return YES;
    }
    /**发送支付宝支付结果的通知*/

        }
    }
