Amazon Cognito iOS SDK V2使用Facebook和Google+提供程序身份验证的问题

[英]Issues with Amazon Cognito iOS SDK V2 using Facebook and Google+ Provider Authentication

我目前无法使用Facebook和Google+作为提供商授权使用AWS iOS SDK V2的用户。

我不确定它是我在AWS Developer Console上的设置,还是它的代码。

这是标识池的角色策略:

{  
"Version": "2012-10-17",  
"Statement": [{  
    "Action": [  
        "mobileanalytics:PutEvents",  
        "cognito-sync:*"  
    ],  
    "Effect": "Allow",  
    "Resource": ["*"]  
}]  

我确实收到了未经授权的Cognito ID,但当我尝试使用Facebook或Google+提供商身份验证时,它无效。

未经身份验证的用户确认

一旦Facebook登录返回,我就可以成功使用用户属性来提取个人资料图片,姓名和电子邮件地址。 然后我从Facebook会话中获取令牌(是的,它是一个很长的字符串)并在deviceID类中使用它:

- (void)loginViewFetchedUserInfo:(FBLoginView *)loginView
                        user:(id<FBGraphUser>)user {

//Populate viewcontoller with Facebook data
self.profilePictureView.profileID = user.id;
NSRange range = [user.name rangeOfString:@" "];
self.firstName.text = [user.name substringToIndex:range.location];
self.lastName.text = [user.name substringFromIndex:range.location+1];
self.emailAddress.text = [user objectForKey:@"email"];

//Get Facebook token, set then get Cognito device ID - in DeviceId class
NSString *token = FBSession.activeSession.accessTokenData.accessToken;
DeviceId *myDeviceId = [DeviceId sharedInstance];

cognitoDeviceId = [myDeviceId setFacebookToken:token];

}

DeviceID类实现如下所示:

#import "DeviceId.h"
#import <AWSiOSSDKv2/AWSCore.h>
#import <AWSCognitoSync/Cognito.h>

@implementation DeviceId

static NSString *cognitoId;
static DeviceId *_sharedInstance;
static AWSCognitoCredentialsProvider *credentialsProvider;
static AWSServiceConfiguration *configuration;

+ (DeviceId *) sharedInstance
{
    if (!_sharedInstance)
    {
        _sharedInstance = [[DeviceId alloc] init];
    }

    return _sharedInstance;
}

- (NSString *) getDeviceId
{
    return cognitoId;
}

- (void) setDeviceId
{
    /*
     * AWS Cognito
     */

        credentialsProvider = [AWSCognitoCredentialsProvider
                            credentialsWithRegionType:AWSRegionUSEast1
                            accountId:@"(accountID"
                            identityPoolId:@"(identityPool)"
                            unauthRoleArn:@"arn:aws:iam::(accountID):role/Cognito_(app)UsersUnauth_DefaultRole"
                            authRoleArn:@"arn:aws:iam::(accountID):role/Cognito_(app)UsersAuth_DefaultRole"];

        configuration = [AWSServiceConfiguration configurationWithRegion:AWSRegionUSEast1
                                                                          credentialsProvider:credentialsProvider];

        [AWSServiceManager defaultServiceManager].defaultServiceConfiguration = configuration;

    // Retrieve the cognito ID.
    cognitoId = credentialsProvider.identityId;

    if (!cognitoId) {
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Identification Error"
                                                        message:@"Error on User Account."
                                                       delegate:nil
                                              cancelButtonTitle:@"OK"
                                              otherButtonTitles:nil];
        [alert show];
    }
}

-(NSString *)setFacebookToken:(NSString*)token {

    credentialsProvider.logins = @{ @(AWSCognitoLoginProviderKeyFacebook): token };
    [self setDeviceId];
    return cognitoId;
}

-(NSString *)setGooglePlusToken:(NSString*)token {
    credentialsProvider.logins = @{ @(AWSCognitoLoginProviderKeyGoogle): token };
    [self setDeviceId];
    return cognitoId;
}

@end

我没有收到任何错误消息,上面的仪表板从未显示经过身份验证的用户。 CognitoID永远不会改变它的价值。 谁能告诉我问题出在哪里?

编辑:根据评论更新的DeviceId.m仍然为cognitoId返回nil

编辑2:更新了DeviceId.m以替换while循环检查BFTask是否已完成Bolts方法waitUntilFinished。

#import "DeviceId.h"
#import <AWSiOSSDKv2/AWSCore.h>
#import <AWSCognitoSync/Cognito.h>


@implementation DeviceId
{
    __block NSString *tempCognitoId;
}

static NSString *cognitoId;
static DeviceId *_sharedInstance;
static AWSCognitoCredentialsProvider *credentialsProvider;
static AWSServiceConfiguration *configuration;

+ (DeviceId *) sharedInstance
{
    if (!_sharedInstance)
    {
        _sharedInstance = [[DeviceId alloc] init];
    }

    return _sharedInstance;
}

- (NSString *) getDeviceId
{
    return cognitoId;
}

- (void) setDeviceId
{
    /*
     * AWS Cognito
     */

    credentialsProvider = [AWSCognitoCredentialsProvider
                                                          credentialsWithRegionType:AWSRegionUSEast1
                                                          identityPoolId:@"Identity Pool ID"];

    configuration = [AWSServiceConfiguration
                                              configurationWithRegion:AWSRegionUSEast1
                                              credentialsProvider:credentialsProvider];

    [AWSServiceManager defaultServiceManager].defaultServiceConfiguration = configuration;

    BFTask *taskIdentity = [[credentialsProvider refresh] continueWithBlock:^id(BFTask *task){

        if (task.error == nil)
        {
            tempCognitoId = credentialsProvider.identityId;
            NSLog(@"cognitoId: %@", cognitoId);
        }
        else
        {
            NSLog(@"Error : %@", task.error);
        }

        return nil;
    }];

    [taskIdentity waitUntilFinished];

    cognitoId = tempCognitoId;

}

-(NSString *)setFacebookToken:(NSString*)token {

    credentialsProvider.logins = @{ @(AWSCognitoLoginProviderKeyFacebook): token };
    BFTask *taskIdentity = [[credentialsProvider refresh] continueWithBlock:^id(BFTask *task){

        if (task.error == nil)
        {
            tempCognitoId = credentialsProvider.identityId;
            NSLog(@"cognitoId: %@", tempCognitoId);
        }
        else
        {
            NSLog(@"Error : %@", task.error);
        }

        return nil;
    }];

    [taskIdentity waitUntilFinished];

    cognitoId = tempCognitoId;

    return cognitoId;
}

-(NSString *)setGooglePlusToken:(NSString*)token {
    credentialsProvider.logins = @{ @(AWSCognitoLoginProviderKeyGoogle): token };
    BFTask *taskIdentity = [[credentialsProvider getIdentityId] continueWithBlock:^id(BFTask *task){

        if (task.error == nil)
        {
            tempCognitoId = credentialsProvider.identityId;
            NSLog(@"cognitoId: %@", tempCognitoId);
        }
        else
        {
            NSLog(@"Error : %@", task.error);
        }

        return nil;
    }];

    [taskIdentity waitUntilFinished];

    cognitoId = tempCognitoId;

    return cognitoId;
}

@end

我确实意识到有些人可能会考虑等待完成是不好的做法,但我需要确保测试目的,即“同步”返回cognitoId。 修改Facebook App ID后,使用此方法返回cognitoID。

编辑3:但是,Google+在到达deviceId之前失败了。

- (void)finishedWithAuth:(GTMOAuth2Authentication *)auth
               error:(NSError *)error {
    if (error) {
        _signInAuthStatus.text =
        [NSString stringWithFormat:@"Status: Authentication error: %@", error];
        NSLog(@"%@", error);
        return;
    }
    NSString *idToken = [auth.parameters objectForKey:@"id_token"];
    DeviceId *myDeviceId = [DeviceId sharedInstance];
    [myDeviceId setGooglePlusToken:idToken];
}

打印出NSLog错误:Error Domain = com.google.GooglePlusPlatform Code = -1“无法完成操作。(com.google.HTTPStatus错误400.)”API和Auth产品名称和当前电子邮件地址似乎是在控制台上更正。

编辑4:代码的另一部分中的Cognito Synch现在已停止工作:

    AWSCognito *syncClient = [AWSCognito defaultCognito];
    AWSCognitoDataset *dataset = [syncClient openOrCreateDataset:@"myDataSet"];
    NSString *fullName = [dataset stringForKey:@"name"];

第一行失败,出现错误:

***由于未捕获的异常'NSInvalidArgumentException'终止应用程序,原因:'+ [AWSEndpoint endpointWithRegion:service:]:无法识别的选择器发送给类

对这些额外错误的任何帮助表示赞赏。

看起来,在credentialsProvider.logins映射中设置令牌后,您将通过再次调用setDeviceId来覆盖您的credentialsProvider。 setDeviceId创建一个全新的AWSCognitoCredentialsProvider,它不会将您添加到上一个的令牌,并覆盖变量credentialsProvider。

您描述的问题的常见原因

错误域= com.google.GooglePlusPlatform代码= -1“无法完成操作。(com.google.HTTPStatus错误400.)

此stackoverflow问题中描述。 我会仔细检查您是否输入了产品名称和电子邮件地址。 此外,我相信您在输入此数据后必须重新创建OAuth凭据,因此如果您还没有这样做,则可能值得尝试。

最后,检查您是否使用Web服务器API密钥, 而不是 iOS客户端密钥。
