ios - Cognito 身份验证有效但显示错误？

Question

基本上，我使用经过开发人员身份验证的身份来验证我的用户。即使显示此错误:

AWSiOSSDKv2 [Verbose] AWSURLResponseSerialization.m line:87 | -[AWSJSONResponseSerializer responseObjectForResponse:originalRequest:currentRequest:data:error:] | Response body: [{"__type":"InvalidParameterException","message":"Please provide a valid public provider"}] 2015-10-20 17:50:19.251 BusyTime[56549:7365231] AWSiOSSDKv2 [Error] AWSCredentialsProvider.m line:435 | __73-[AWSCognitoCredentialsProvider getCredentialsWithCognito:authenticated:]_block_invoke | GetCredentialsForIdentity failed. Error is [Error Domain=com.amazonaws.AWSCognitoIdentityErrorDomain Code=7 "The operation couldn’t be completed. (com.amazonaws.AWSCognitoIdentityErrorDomain error 7.)" UserInfo=0x7f9d9342dde0 {__type=InvalidParameterException, message=Please provide a valid public provider}]

虽然显示此错误，但我仍在返回我的 identityId 和 Token 并成功调用需要经过身份验证的权限才能调用的 lambda 方法。我相信这与我的刷新方法有关，但我不确定。请帮我处理这个错误。

我的凭据提供商代码:

NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];

    [AWSLogger defaultLogger].logLevel = AWSLogLevelVerbose;
    id<AWSCognitoIdentityProvider> identityProvider = [[BusytimeAuthenticated alloc] initWithRegionType:AWSRegionUSEast1
                                                                                             identityId:nil
                                                                                         identityPoolId:@"EXAMPLEPOOLID"
                                                                                logins:@{@"login.busytimeapp": [defaults objectForKey:@"username"]}
                                                                                           providerName:@"login.busytimeapp"
                                                       ];

    credentialsProvider = [[AWSCognitoCredentialsProvider alloc] initWithRegionType:AWSRegionUSEast1
                                                                   identityProvider:identityProvider
                                                                      unauthRoleArn:nil
                                                                        authRoleArn:nil];

    configuration = [[AWSServiceConfiguration alloc] initWithRegion:AWSRegionUSEast1
                                                credentialsProvider:self.credentialsProvider];
    AWSServiceManager.defaultServiceManager.defaultServiceConfiguration = configuration;
    [[credentialsProvider refresh] continueWithBlock:^id(BFTask *task){
        [self testAuth];
        return nil;
    }];

我的刷新方法:

- (BFTask *)refresh {
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    if (![self authenticatedWithProvider]) {
        return [super getIdentityId];
    }else{
        NSDictionary *post = [[NSDictionary alloc] initWithObjectsAndKeys:
                              [defaults objectForKey:@"username"], @"username",
                              [defaults objectForKey:@"password"], @"password",
                              nil];
        NSError *error;
        NSData *postData = [NSJSONSerialization dataWithJSONObject:post options:0 error:&error];
        NSString *postLength = [NSString stringWithFormat:@"%lu", (unsigned long)[postData length]];
        NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
        [request setURL:[NSURL URLWithString:@"SOMEURL"]];
        [request setHTTPMethod:@"POST"];
        [request setValue:postLength forHTTPHeaderField:@"Content-Length"];
        [request setHTTPBody:postData];
        NSURLSession *session = [NSURLSession sessionWithConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
        __block BOOL isLogged = false;
        [[session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
            NSDictionary *newJSON = [NSJSONSerialization JSONObjectWithData:data
                                                                    options:0
                                                                      error:&error];
            isLogged = true;
            if(!newJSON){
                NSLog(@"DID NOT AUTHENTICATE");
            }else{

            self.identityId = [newJSON objectForKey:@"IdentityId" ];
            self.token = [newJSON objectForKey:@"Token" ];
            NSLog(@"Result: %@", newJSON);
            }

        }] resume];

        return [super getIdentityId];

    }
    return [super getIdentityId];
}

这里的问题是您将登录映射中的登录提供商名称作为键传递。您不能对开发人员身份验证身份执行此操作。

相反，您应该在 map 中使用 Cognito 身份提供商名称 cognito-identity.amazonaws.com，就像它在 documentation 中所说的那样.这应该可以解决您的异常。
