CLI

AWS CLI

L'esempio seguente utilizza il put-object comando per caricare un oggetto su Amazon S3:


aws s3api put-object --bucket text-content --key dir-1/my_images.tar.bz2 --body my_images.tar.bz2

L'esempio seguente mostra il caricamento di un file video (il file video viene specificato utilizzando la sintassi del file system Windows. ):


aws s3api put-object --bucket text-content --key dir-1/big-video-file.mp4 --body e:\media\videos\f-sharp-3-data-services.mp4

Per ulteriori informazioni sul caricamento di oggetti, consulta Uploading Objects nella Amazon S3 Developer Guide.

PowerShell

Strumenti per PowerShell

Esempio 1: questo comando carica il singolo file "local-sample.txt" su Amazon S3, creando un oggetto con la chiave "sample.txt" nel bucket «test-files».


Write-S3Object -BucketName test-files -Key "sample.txt" -File .\local-sample.txt

Esempio 2: questo comando carica il singolo file "sample.txt" su Amazon S3, creando un oggetto con la chiave "sample.txt" nel bucket «test-files». Se il parametro -Key non viene fornito, il nome del file viene utilizzato come chiave dell'oggetto S3.


Write-S3Object -BucketName test-files -File .\sample.txt

Esempio 3: questo comando carica il singolo file "local-sample.txt" su Amazon S3, creando un oggetto con la chiave "prefix/to/sample.txt" nel bucket «test-files».


Write-S3Object -BucketName test-files -Key "prefix/to/sample.txt" -File .\local-sample.txt

Esempio 4: questo comando carica tutti i file nella sottodirectory «Scripts» nel bucket «test-files» e applica il prefisso chiave comune "" a ciascun oggetto. SampleScripts Ogni file caricato avrà una chiave "SampleScripts/filename" dove 'filename' varia.


Write-S3Object -BucketName test-files -Folder .\Scripts -KeyPrefix SampleScripts\

Esempio 5: questo comando carica tutti i file*.ps1 nella directory locale «Scripts» nel bucket «test-files» e applica il prefisso chiave comune "" a ciascun oggetto. SampleScripts Ogni file caricato avrà una chiave "/filename.ps1" dove 'filename' varia. SampleScripts


Write-S3Object -BucketName test-files -Folder .\Scripts -KeyPrefix SampleScripts\ -SearchPattern *.ps1

Esempio 6: questo comando crea un nuovo oggetto S3 contenente la stringa di contenuto specificata con la chiave 'sample.txt'.


Write-S3Object -BucketName test-files -Key "sample.txt" -Content "object contents"

Esempio 7: questo comando carica il file specificato (il nome del file viene utilizzato come chiave) e applica i tag specificati al nuovo oggetto.


Write-S3Object -BucketName test-files -File "sample.txt" -TagSet @{Key="key1";Value="value1"},@{Key="key2";Value="value2"}

Esempio 8: questo comando carica in modo ricorsivo la cartella specificata e applica i tag specificati a tutti i nuovi oggetti.


Write-S3Object -BucketName test-files -Folder . -KeyPrefix "TaggedFiles" -Recurse -TagSet @{Key="key1";Value="value1"},@{Key="key2";Value="value2"}
