Namespace AjaxUploader.Providers

Classes

Azure

Global entry point for direct-to-Azure-Blob upload support. Assign Signer once at startup. When null, the /azure/* endpoints respond with 501 Not Implemented.

AjaxUploader.Providers.Azure.Signer = new MyAzureSigner(connectionString, container);

AzureAbortRequest

AzureCompleteRequest

AzureCompleteResult

AzureCreateRequest

AzureCreateResult

FileSystemProvider

Default provider that stores uploads and metadata in the local file system.

Gcs

Global entry point for direct-to-GCS upload support. Set Signer once at startup; when null, the /gcs/* endpoints respond with 501 Not Implemented.

AjaxUploader.Providers.Gcs.Signer = new MyGcsSigner(options);

GcsAbortRequest

GcsCompleteRequest

GcsCompleteResult

GcsCreateRequest

GcsCreateResult

GcsSignRequest

GcsSignResult

GcsSignerOptions

Configuration for a built-in IGcsSigner implementation. Host apps may either implement IGcsSigner directly or instantiate a reference implementation with one of these option sets.

ProviderFactory

Static factory for IUploaderProvider. The default provider is FileSystemProvider, but applications can replace it with a custom implementation.

S3

Global entry point for direct-to-S3 upload support. Set Signer once at startup; when null, the /s3/* handler routes respond with 501 Not Implemented.

AjaxUploader.Providers.S3.Signer = new MyS3Signer(bucket, region, credentials);

S3AbortRequest

S3CompleteRequest

S3CompleteResult

S3CreateRequest

S3CreateResult

S3ETag

Normalises S3 ETags at the handler boundary.

S3ListPartsRequest

Request for the optional ListParts signer capability. Implement a public S3ListPartsResult ListParts(S3ListPartsRequest request) method on your signer to let resuming clients reconcile their persisted part maps against what S3 actually holds. The capability is discovered via reflection - it is deliberately NOT part of IS3Signer so existing implementations keep compiling (.NET Framework has no default interface members).

S3ListPartsResult

Result of the optional ListParts signer capability.

S3Part

S3SignRequest

S3SignResult

S3StoredPart

A part S3 reports as stored for an in-progress multipart upload.

Interfaces

IAzureSigner

Bridges AjaxUploader to an Azure Blob Storage upload session using a pre-signed blob SAS URL. The browser uses the SAS to PutBlock and PutBlockList directly; the server only signs and records metadata. The core library takes no Azure SDK dependency - host apps plug in their own signer by setting Signer.

IGcsSigner

Bridges AjaxUploader to a Google Cloud Storage resumable upload session. The core library takes no Google.Cloud.Storage SDK dependency - host apps plug in their own signer by setting Signer at startup.

GCS resumable upload flow:

1. CreateUpload(GcsCreateRequest) calls POST /upload/storage/v1/b/{bucket}/o?uploadType=resumable and returns the session URI (the Location response header).
2. The browser PUTs chunks directly to the session URI with Content-Range headers - no per-chunk signing is required by GCS, but SignChunk(GcsSignRequest) is provided for hosts that wrap the session URI with their own short-lived signed URL (e.g. when the session URI is held server-side).
3. CompleteUpload(GcsCompleteRequest) records the finalised object.
4. AbortUpload(GcsAbortRequest) issues DELETE against the session URI to free resources.

IS3Signer

Bridges AjaxUploader to an S3-compatible multipart upload session. The core library takes no AWS SDK dependency - host apps plug in their own signer by setting Signer at startup (e.g. in Global.asax). Works for any S3-API-compatible backend (AWS S3, MinIO, Backblaze B2, R2, Wasabi, etc.).

IUploaderProvider

Defines the storage operations used by AjaxUploader to save, read, and maintain uploaded files. Providers abstract where file contents and metadata live.
