Medya Yükleme
Koleksiyonlar ile düzeninizi koruyun
İçeriği tercihlerinize göre kaydedin ve kategorilere ayırın.
Birçok API yöntemi, normal bir yayıncıya ek olarak medya yüklemeyi de destekler.
Bu durumda normal istek yöntemi aşırı yüklenir.
Yüklemek için Stream.
Genel Bakış
Yüklemek istediğiniz tüm Stream için devam ettirilebilir
medya yükleme özelliği, akışların daha küçük parçalar halinde yüklenmesine olanak tanır.
Bu, özellikle büyük boyutlu dosyalar aktarıyorsanız
ve şebeke kesintisinin ya da başka bir iletimin
yüksek olduğunu gösterir.
Ayrıca, ağ arızası durumunda bant genişliği kullanımınızı da azaltabilir.
çünkü büyük dosya yüklemelerini baştan başlatmanız gerekmez.
Devam Ettirilebilir Medya Yükleme, Google API .NET istemci kitaplığında mevcut bir özelliktir
1.2.0-beta sürümünden itibaren geçerlidir.
Google API'ye özel kitaplıklar,
bu özellikle etkileşimde bulunabilirsiniz.

Bu uygulamada, medya içeriği parçalar halinde yüklenir.
Varsayılan yığın boyutu 10 MB'tır, ancak
istekteki ChunkSize özelliğinin 256 KB'lık herhangi bir katı olarak ayarlanması gerekir.
İstekte bir sunucu hatasıyla karşılaşılırsa eksponansiyel geri yükleme
politikası, başarıyla yüklenmeyen baytları yeniden göndermek için kullanılır.
Varsayılan olarak her istemci isteği için eksponansiyel geri yükleme etkindir.
Yeni bir URL oluştururken varsayılan davranışı
yeni bir hizmet nesnesini
BaseClientService.Initializer tarihinde DefaultExponentialBackOffPolicy mülkü
ve/veya
HttpClientInitializer
özelliğini kullanarak IConfigurableHttpClientInitializer
geri çekilme politikası ekler.
Medya yüklemeyi destekleyen yöntemler,
referans belgelerde bulabilirsiniz.
Bu API yöntemlerinde Upload ve
UploadAsync yöntem eklendi.
Bu yöntemlerde yükleme için Stream ve parametre olarak içerik türü gerekir.
Yüklediğiniz akışın konumunun 0 olduğundan emin olun. Aksi takdirde şunun gibi bir hata alırsınız:
"System.InvalidOperationException: Belirtilen başlık bulunamadı".
Çerçevenin HttpClient davranışı nedeniyle
sınıfı, yükleme zaman aşımına uğrarsa bir TaskCanceledException atılır.

Örnek Kod
// Create the service using the client credentials.
var service = new DriveService(new BaseClientService.Initializer()
{
HttpClientInitializer = credential,
ApplicationName = "Application_Name"
});
using var uploadStream = System.IO.File.OpenRead("Local_File_Name");
// Create the File resource to upload.
Google.Apis.Drive.v3.Data.File driveFile = new Google.Apis.Drive.v3.Data.File
{
Name = "Drive_File_Name"
};
// Get the media upload request object.
FilesResource.CreateMediaUpload insertRequest = service.Files.Create(
driveFile, uploadStream, "image/jpeg");
// Add handlers which will be notified on progress changes and upload completion.
// Notification of progress changed will be invoked when the upload was started,
// on each upload chunk, and on success or failure.
insertRequest.ProgressChanged += Upload_ProgressChanged;
insertRequest.ResponseReceived += Upload_ResponseReceived;
await insertRequest.UploadAsync();
static void Upload_ProgressChanged(IUploadProgress progress) =>
Console.WriteLine(progress.Status + " " + progress.BytesSent);
static void Upload_ResponseReceived(Google.Apis.Drive.v3.Data.File file) =>
Console.WriteLine(file.Name + " was uploaded successfully");

case, the regular request method is overloaded to get an additional\n`Stream` to upload.\n\nOverview\n--------\n\n\nFor any `Stream` you wish to upload, you should use resumable\nmedia upload, which allows streams to be uploaded in smaller chunks.\nThis is especially useful if you are transferring large files,\nand the likelihood of a network interruption or some other transmission\nfailure is high.\nIt can also reduce your bandwidth usage in the event of network failures\nbecause you don't have to restart large file uploads from the beginning.\n\nResumableMediaUpload\n--------------------\n\n\nResumable Media Upload has been a feature in the Google API .NET client library\nsince 1.2.0-beta.\nThe Google API-specific libraries contain convenience methods for\ninteracting with this feature.\n\n\nThe resumable media upload protocol is described, for example, on the\n[media upload page for the Drive API](https://developers.google.com/drive/manage-uploads#resumable).\nThe main class of interest is\n[`ResumableUpload`](https://googleapis.dev/dotnet/Google.Apis/latest/api/Google.Apis.Upload.ResumableUpload.html).\nIn this implementation, the media content is uploaded in chunks.\n\n\nThe default chunk size is 10MB, but you can change it by\nsetting the `ChunkSize` property on the request to any multiple of 256KB.\nIf a server error is encountered in a request then exponential backoff\npolicy is used to resend the bytes that were not successfully uploaded.\nBy default, exponential backoff is enabled for each client request.\nYou can change the default behavior when you construct\na new service object by changing the\n[`DefaultExponentialBackOffPolicy`](https://googleapis.dev/dotnet/Google.Apis/latest/api/Google.Apis.Services.BaseClientService.Initializer.html#Google_Apis_Services_BaseClientService_Initializer_DefaultExponentialBackOffPolicy) property on `BaseClientService.Initializer`\nand/or setting the\n[`HttpClientInitializer`](https://googleapis.dev/dotnet/Google.Apis/latest/api/Google.Apis.Services.BaseClientService.Initializer.html#Google_Apis_Services_BaseClientService_Initializer_HttpClientInitializer)\nproperty to your own implementation of `IConfigurableHttpClientInitializer`\nthat adds some backoff policy.\n\n\nThe methods that support media upload are identified\nin the reference documentation for the API-specific documentation.\nFor these API methods, convenience `Upload` and\n`UploadAsync` methods are added.\nThose methods take a `Stream` to upload and its content type as parameters.\n\n\nMake sure that the position of the stream you upload is 0, otherwise you will receive an error, such as\n\"System.InvalidOperationException: The given header was not found\".\n\n\nNote that due to the behavior of the framework's `HttpClient`\nclass, if the upload times out, a `TaskCanceledException` is thrown.\nIf you see this exception, consider manually increasing the `Timeout` property in\nthe client used by your service object.\n\nSample Code\n-----------\n\n```gdscript\n// Create the service using the client credentials.\nvar service = new DriveService(new BaseClientService.Initializer()\n{\n HttpClientInitializer = credential,\n ApplicationName = \"Application_Name\"\n});\n\nusing var uploadStream = System.IO.File.OpenRead(\"Local_File_Name\");\n\n// Create the File resource to upload.\nGoogle.Apis.Drive.v3.Data.File driveFile = new Google.Apis.Drive.v3.Data.File\n{\n Name = \"Drive_File_Name\"\n};\n// Get the media upload request object.\nFilesResource.CreateMediaUpload insertRequest = service.Files.Create(\n driveFile, uploadStream, \"image/jpeg\");\n\n// Add handlers which will be notified on progress changes and upload completion.\n// Notification of progress changed will be invoked when the upload was started,\n// on each upload chunk, and on success or failure.\ninsertRequest.ProgressChanged += Upload_ProgressChanged;\ninsertRequest.ResponseReceived += Upload_ResponseReceived;\n\nawait insertRequest.UploadAsync();\n\nstatic void Upload_ProgressChanged(IUploadProgress progress) =\u003e\n Console.WriteLine(progress.Status + \" \" + progress.BytesSent);\n\nstatic void Upload_ResponseReceived(Google.Apis.Drive.v3.Data.File file) =\u003e\n Console.WriteLine(file.Name + \" was uploaded successfully\");\n```"]]
