检查 Amazon Cognito 角色（Auth 与 Unauth）

Question

我刚开始使用 AWS 作为我的 iOS 移动应用程序的后端。我已经设置了所需的所有角色和身份池。我已将以下代码添加到我的 AppDelegate.m 文件中：

// Starting AWS
AWSCognitoCredentialsProvider *credentialsProvider = [[AWSCognitoCredentialsProvider alloc] initWithRegionType:AWSRegionUSEast1 identityPoolId:@"IdentityPool"];

AWSServiceConfiguration *configuration = [[AWSServiceConfiguration alloc] initWithRegion:AWSRegionUSEast1 credentialsProvider:credentialsProvider];

下一步要查看我是否已通过身份验证？试图弄清楚 iOS 代码，看看我是什么角色。

AWSServiceManager.defaultServiceManager.defaultServiceConfiguration = configuration;

Answer 1

在您想要使用 AWS 的地方导入服务标头，然后尝试调用 AWS 服务。

AWSS3Transfermanager *transferManager = [AWSS3Transfermanager defaultS3TransferManager];
AWSS3TransferManagerUploadRequest *uploadRequest = [AWSS3TransferManagerUploadRequest new];
uploadRequest.bucket = yourBucket;
uploadRequest.key = yourKey;
uploadRequest.body = yourDataURL;
uploadRequest.contentLength = [NSNumber numberWithUnsignedLongLong:fileSize];

[[transferManager upload:uploadRequest] continueWithBlock:^id(AWSTask *task) {
    // Do something with the response
    return nil;
}];
