我正在尝试使用amazon cognito与开发人员身份验证身份.我的API成功返回了id和令牌.但是,当我使用这些令牌将内容上传到S3时,我收到以下错误:

Not authorized to perform sts:AssumeRoleWithWebIdentity

以下是我设置凭据提供程序的代码.

ZGAWSIdentityProvider *identityProvider = [ZGAWSIdentityProvider new];
[identityProvider setIdentityPoolId:AWS_IDENTITY_POOL_ID];

AWSCognitoCredentialsProvider *credentialsProvider = [[AWSCognitoCredentialsProvider alloc]
                                           initWithRegionType:AWSRegionUSEast1
                                           identityProvider:identityProvider
                                           unauthRoleArn:AWS_UNAUTH_ROLE_ARN
                                           authRoleArn:AWS_AUTH_ROLE_ARN];


AWSServiceConfiguration *configuration = [AWSServiceConfiguration configurationWithRegion:AWSRegionUSWest1
                                                                      credentialsProvider:credentialsProvider];

[AWSServiceManager defaultServiceManager].defaultServiceConfiguration = configuration;

而且我在使用所提供的模板http://docs.aws.amazon.com/mobile/sdkforios/developerguide/cognito-auth.html#create-an-identity-pool-that-supports-developer-authenticated-identities到创建身份提供者.

@implementation ZGAWSIdentityProvider
@synthesize identityPoolId=_identityPoolId;
@synthesize identityId=_identityId;
@synthesize token=_token;


- (BFTask *)getIdentityId {
    // Should ensure that identityId property is valid. The below code can probably
    // be used for most use cases.

    if (self.identityId) {
        return [BFTask taskWithResult:nil];
    } else {
        return [[BFTask …
