自定义C2SBidding广告

一、流程说明

TradPlusSDK也支持自定义的C2SBidding广告方便您使用我们服务器的bidding竞价功能。

C2SBidding和普通自定义广告差别在于加载流程。广告展示流程是一致的。

C2SBidding的加载流程如图：

⚠️ 返回给TradPlusSDK的ECPM单位需要与TradPlus后台添加自定义广告源时选择的货币单位保持一致

二、集成说明

1. 创建自定义Adapter

创建您在 TradPlus后台登记的自定义类，并继承TradPlusBaseAdapter

#import <TradPlusAds/TradPlusBaseAdapter.h>
@interface ClassName : TradPlusBaseAdapter

@end

2. 实现TradPlusSDK相关调用

自定义Adapter需实现接口- (BOOL)extraActWithEvent:(NSString *)event info:(NSDictionary *)config及相关流程
event="C2SBidding"，SDK开始竞价流程，自定义Adapter需要从三方SDK相关接口获取ECPM。
event="LoadAdC2SBidding"，竞价已经结束进行加载流程中，自定义Adapter需要根据三方SDK进行加载流程。
当获取ECPM后自定义Adapter需要通过接口 - (void)ADLoadExtraCallbackWithEvent:(NSString *)event info:(NSDictionary *)info返回给SDK。
获取成功：event="C2SBiddingFinish",并将三方版本号及ECPM通过info数据回传给TradPlusSDK。
获取失败：event="C2SBiddingFail",并将错误说明通过info数据回传给TradPlusSDK。

//根据event实现相关流程
- (BOOL)extraActWithEvent:(NSString *)event info:(NSDictionary *)config
{
    if([event isEqualToString:@"C2SBidding"])
    {
		//从三方SDK获取价格
		[self getECPMC2SBidding];
		
		//获取到ecpm后返回给TradPlusSDK
		NSDictionary *dic = @{@"ecpm":"ecpmStr",@"version":"三方版本号"};
    	[self ADLoadExtraCallbackWithEvent:@"C2SBiddingFinish" info:dic];
		
		//如果获取失败则返回获取失败及相关错误信息
		NSDictionary *dic = @{@"error":errorStr};
   	    [self ADLoadExtraCallbackWithEvent:@"C2SBiddingFail" info:dic];
    }
    else if([event isEqualToString:@"LoadAdC2SBidding"])
    {
		//竞价成功后的加载
		[self loadAdC2SBidding];
    }
    else
    {
        return NO;
    }
    return YES;
}

三、C2SBidding示例说明

C2SBidding获取ECPM并加载广告的流程一般有两种

常见流程：广告和ECPM同时拿到，例如：百度的C2SBidding
其他流程：先获取ECPM，竞价成功后在请求获取广告，例如：InMobi的横幅和插屏

1.广告和ECPM同时拿到的示例

百度插屏示例

//在收到SDK相关调用进行相关操作流程
- (BOOL)extraActWithEvent:(NSString *)event info:(NSDictionary *)config
{
    if([event isEqualToString:@"C2SBidding"])
    {
		//从三方SDK获取价格
        [self getECPMC2SBidding];
    }
    else if([event isEqualToString:@"LoadAdC2SBidding"])
    {
		//竞价成功后的加载流程
        [self loadAdC2SBidding];
    }
    else
    {
        return NO;
    }
    return YES;
}

在三方广告对象加载完成后获取ECPM

- (void)getECPMC2SBidding
{
	[self loadAdWithWaterfallItem:self.waterfallItem];
}

//通过三方SDK广告对象进行加载操作
- (void)loadAdWithWaterfallItem:(TradPlusAdWaterfallItem *)item
{
    self.appId = item.config[@"appId"];
    NSString *placementId = item.config[@"placementId"];
    if(placementId == nil || self.appId == nil)
    {
        [self AdConfigError];
        return;
    }
	//通过三方广告对象进行加载
    self.expressFullscreenVideoAd = [[BaiduMobAdExpressFullScreenVideo alloc] init];
    self.expressFullscreenVideoAd.delegate = self;
    self.expressFullscreenVideoAd.AdUnitTag = placementId;
    self.expressFullscreenVideoAd.publisherId = self.appId;
    self.expressFullscreenVideoAd.adType = BaiduMobAdTypeFullScreenVideo;
    [self.expressFullscreenVideoAd load];
}


#pragma mark - BaiduMobAdExpressFullScreenVideoDelegate

//通过三方SDK 加载成功回调获取广告对象中ecpm
- (void)fullScreenVideoAdLoaded:(BaiduMobAdExpressFullScreenVideo *)video
{
	//三方版本号
	NSString *version = SDK_VERSION_IN_MSSP;
	//广告对象的ECPM
	NSString *ecpmStr = [video getECPMLevel];
	//通过接口返回给SDK
	NSDictionary *dic = @{@"ecpm":ecpmStr,@"version":version};
    [self ADLoadExtraCallbackWithEvent:@"C2SBiddingFinish" info:dic];
}

- (void)fullScreenVideoAdLoadFailCode:(NSString *)errCode message:(NSString *)message fullScreenAd:(BaiduMobAdExpressFullScreenVideo *)video
{
	//加载失败，将错误信息回传给TradPlusSDK
	NSString *errorStr = [NSString stringWithFormat:@"errCode: %@, errMsg: %@", errCode, message];
	NSDictionary *dic = @{@"error":errorStr};
    [self ADLoadExtraCallbackWithEvent:@"C2SBiddingFail" info:dic];
}

竞价成功后的加载

//由于之前的获取ECPM时三方广告对象已加载完成了，
//所以只需要在确认广告是有效后直接向TradPlusSDK返回加载完成就可以了。
- (void)loadAdC2SBidding
{
    if([self isReady])
    {
		//返回加载成功
        [self AdLoadFinsh];
    }
    else
    {
		//无效时返回加载失败
        NSError *loadError = [NSError errorWithDomain:@"baidu.interstitial" code:402 userInfo:@{NSLocalizedDescriptionKey : @"C2S Interstitial not ready"}];
        [self AdLoadFailWithError:loadError];
    }
}

//通过三方SDK确认广告是否有效
- (BOOL)isReady
{
    return self.expressFullscreenVideoAd.isReady;
}

参考示例：CustomBidBaiduInterstitialAdapter

2.先获取ECPM后请求广告的示例

Inmobi插屏示例

//在收到SDK相关调用进行相关操作流程
- (BOOL)extraActWithEvent:(NSString *)event info:(NSDictionary *)config
{
    if([event isEqualToString:@"C2SBidding"])
    {
		//从三方SDK获取价格
        [self getECPMC2SBidding];
    }
    else if([event isEqualToString:@"LoadAdC2SBidding"])
    {
		//竞价成功后的加载流程
        [self loadAdC2SBidding];
    }
    else
    {
        return NO;
    }
    return YES;
}

从三方SDK获取ECPM预加载接口获取ECPM的流程

- (void)getECPMC2SBidding
{
	
	NSString *account_id = self.waterfallItem.config[@"account_id"];
    self.placementId = self.waterfallItem.config[@"placementId"];
    if(account_id == nil || [account_id isKindOfClass:[NSNull class]] || self.placementId == nil)
    {
        [self AdConfigError];
        return;
    }
    __weak typeof(self) weakSelf = self;
	//初始化三方SDK，，如已初始化则可以不调用
    [IMSdk initWithAccountID:account_id andCompletionHandler:^(NSError * _Nullable error) {
        [weakSelf startC2SBidding];
    }];
}

//通过三方SDK获取ECPM
- (void)startC2SBidding
{
	self.interstitial = [[IMInterstitial alloc] initWithPlacementId:[self.placementId longLongValue]];
	self.interstitial.delegate = self;
	[self.interstitial.preloadManager preload];
}

#pragma mark - IMInterstitialDelegate

-(void)interstitial:(IMInterstitial*)interstitial didReceiveWithMetaInfo:(IMAdMetaInfo*)metaInfo
{
	//三方版本号
	NSString *version = [IMSdk getVersion];
	//广告对象的ECPM
	NSString *ecpmStr = [NSString stringWithFormat:@"%f",metaInfo.getBid];
	//通过接口返回给SDK
	NSDictionary *dic = @{@"ecpm":ecpmStr,@"version":version};
    [self ADLoadExtraCallbackWithEvent:@"C2SBiddingFinish" info:dic];
}

-(void)interstitial:(IMInterstitial*)interstitial didFailToReceiveWithError:(NSError*)error
{
	//加载失败，将错误信息回传给TradPlusSDK
	NSString *errorStr = [NSString stringWithFormat:@"errCode: %ld, errMsg: %@", (long)error.code, error.localizedDescription];
	NSDictionary *dic = @{@"error":errorStr};
    [self ADLoadExtraCallbackWithEvent:@"C2SBiddingFail" info:dic];
}

竞价成功后的加载

//通过三方API加载广告
- (void)loadAdC2SBidding
{
    [self.interstitial.preloadManager load];
}

#pragma mark - IMInterstitialDelegate

//加载成功
-(void)interstitialDidFinishLoading:(IMInterstitial*)interstitial
{
    [self AdLoadFinsh];
}

//加载失败
-(void)interstitial:(IMInterstitial*)interstitial didFailToLoadWithError:(IMRequestStatus *)error
{
    [self AdLoadFailWithError:error];
}

参考示例：CustomBidInMobiInterstitialAdapter

四、展示广告

展示相关流程可参考各类型的自定义广告

五、通知三方竞价成功和竞价失败

参考示例：CustomBidBaiduInterstitialAdapter

六、常见问题

怎么测试比较方便验证C2SLoss通知

请求的tradplus后台广告位中介组并行数和缓存数都设置为1，除了自定义的广告源，再配置一个必定填充并且很高价的waterfall，比如admob设置999$。这种情况下，自定义接入的广告源应该必定竞价失败会回调loss通知。
