我想使用 iOS SDK 将视频文件从 iPhone 上传到 S3 存储桶？

Question

我想使用 iOS SDK 将视频文件从 iPhone 上传到 S3 存储桶。 我需要帮助。我将图像上传到 Amazon S3，它工作正常，但是当我重写此代码以上传视频时，它出了点问题。

Answer 1

也许您应该在此处粘贴一些代码。此外，AWS SDK 有两个版本，您使用的是最新版本还是已弃用的版本？

Answer 2

请查看amazon documentation，它将帮助您从基础开始，包括，

1. 设置 SDK（使用框架设置 SDK 将是 初学者，详细信息将在此link）中提供）

2. 获取 Cognito 客户端初始化代码（用于 AWS 身份验证 你的应用）

3. 创建和配置 S3 存储桶

完成上述步骤后，您可以轻松地将文件上传到 S3。在您的项目中实现以下代码，

#import <AWSS3/AWSS3.h>
#import <AWSCore/AWSCore.h>
#import <AWSCognito/AWSCognito.h>

- (void)viewDidLoad
{
    [super viewDidLoad];
/* Below three lines are called Cognito client initialization code please change the regiontype and indentityPoolId with yours */  

    AWSCognitoCredentialsProvider *credentialsProvider = [[AWSCognitoCredentialsProvider alloc] initWithRegionType:AWSRegionUSWest2 identityPoolId:@"us-west-2:73ab7333-bqw1-4a8e-b220-9f085cff50yo"];

    AWSServiceConfiguration *configuration = [[AWSServiceConfiguration alloc] initWithRegion:AWSRegionUSWest2 credentialsProvider:credentialsProvider];

    [AWSServiceManager defaultServiceManager].defaultServiceConfiguration = configuration;

    UIImagePickerController *mediaUI = [[UIImagePickerController alloc] init];  
    mediaUI.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;  
    mediaUI.mediaTypes = [[NSArray alloc] initWithObjects: (NSString *) kUTTypeMovie, nil];  
    mediaUI.allowsEditing = YES;  
    mediaUI.delegate = self;  

    [self presentViewController:mediaUI animated:YES completion:nil];  


}

- (void)imagePickerController:(UIImagePickerController *) Picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
    NSString *type = [info objectForKey:UIImagePickerControllerMediaType];  

    if ([type isEqualToString:(NSString *)kUTTypeVideo] ||
        [type isEqualToString:(NSString *)kUTTypeMovie]) { // movie != video  

        NSURL *videoURL = [info objectForKey:UIImagePickerControllerMediaURL];
        [self amazonS3Upload:videoURL];
     }
}

- (void)amazonS3Upload:(NSURL *) uploadUrl
{
    // amazon web service s3 api
    AWSS3TransferManager *transferManager = [AWSS3TransferManager defaultS3TransferManager];

    AWSS3TransferManagerUploadRequest *uploadRequest = [AWSS3TransferManagerUploadRequest new];
    uploadRequest.bucket = @"myTest-bucket"; // Your Bucket Name
    uploadRequest.key = @"myTestFile.mp4"; // Your File Name in Bucket
    uploadRequest.body = uploadUrl;
    uploadRequest.uploadProgress =  ^(int64_t bytesSent, int64_t totalBytesSent, int64_t totalBytesExpectedToSend){
        dispatch_async(dispatch_get_main_queue(), ^{
            //Update progress.
            NSLog(@"UPLOAD PROGRESS: %lld : %lld : %lld", bytesSent,totalBytesSent,totalBytesExpectedToSend);
        });
    };

    [[transferManager upload:uploadRequest] continueWithExecutor:[AWSExecutor mainThreadExecutor]
                withBlock:^id(AWSTask *task) {
                                                           if (task.error) {
                                                               if ([task.error.domain isEqualToString:AWSS3TransferManagerErrorDomain]) {
                                                                   switch (task.error.code) {
                                                                       case AWSS3TransferManagerErrorCancelled:
                                                                       case AWSS3TransferManagerErrorPaused:
                                                                           break;

                                                                       default:
                                                                           NSLog(@"Error: %@", task.error);
                                                                           break;
                                                                   }
                                                               } else {
                                                                   // Unknown error.
                                                                   NSLog(@"Error: %@", task.error);
                                                               }
                                                           }

                                                           if (task.result) {
                                                               AWSS3TransferManagerUploadOutput *uploadOutput = task.result;
                                                               NSLog(@"upload response: %@", uploadOutput);
                                                               // The file uploaded successfully.
                                                           }
