Package azblob allows you to manipulate Azure Storage containers and blobs objects.
URL Types
The most common types you'll work with are the XxxURL types. The methods of these types make requests
against the Azure Storage Service.
- ServiceURL's methods perform operations on a storage account.
- ContainerURL's methods perform operations on an account's container.
- BlockBlobURL's methods perform operations on a container's block blob.
- AppendBlobURL's methods perform operations on a container's append blob.
- PageBlobURL's methods perform operations on a container's page blob.
- BlobURL's methods perform operations on a container's blob regardless of the blob's type.
Internally, each XxxURL object contains a URL and a request pipeline. The URL indicates the endpoint where each HTTP
request is sent and the pipeline indicates how the outgoing HTTP request and incoming HTTP response is processed.
The pipeline specifies things like retry policies, logging, deserializaiton of HTTP response payloads, and more.
Pipelines are threadsafe and may be shared by multiple XxxURL objects. When you create a ServiceURL, you pass
an initial pipeline. When you call ServiceURL's NewContainerURL method, the new ContainerURL object has its own
URL but it shares the same pipeline as the parent ServiceURL object.
To work with a blob, call one of ContainerURL's 4 NewXxxBlobURL methods depending on how you want to treat the blob.
To treat the blob as a block blob, append blob, or page blob, call NewBlockBlobURL, NewAppendBlobURL, or NewPageBlobURL
respectively. These three types are all identical except for the methods they expose; each type exposes the methods
relevant to the type of blob represented. If you're not sure how you want to treat a blob, you can call NewBlobURL;
this returns an object whose methods are relevant to any kind of blob. When you call ContainerURL's NewXxxBlobURL,
the new XxxBlobURL object has its own URL but it shares the same pipeline as the parent ContainerURL object. You
can easily switch between blob types (method sets) by calling a ToXxxBlobURL method.
If you'd like to use a different pipeline with a ServiceURL, ContainerURL, or XxxBlobURL object, then call the XxxURL
object's WithPipeline method passing in the desired pipeline. The WithPipeline methods create a new XxxURL object
with the same URL as the original but with the specified pipeline.
Note that XxxURL objects use little memory, are goroutine-safe, and many objects share the same pipeline. This means that
XxxURL objects share a lot of system resources making them very efficient.
All of XxxURL's methods that make HTTP requests return rich error handling information so you can discern network failures,
transient failures, timeout failures, service failures, etc. See the StorageError interface for more information and an
example of how to do deal with errors.
URL and Shared Access Signature Manipulation
The library includes a BlobURLParts type for deconstructing and reconstructing URLs. And you can use the there are types
for generating and parsing Shared Access Signature (SAS)
- Use the AccountSASSignatureValues type to create a SAS for a storage account
- Use the BlobSASSignatureValues type to create a SAS for a container or blob.
- Use the SASQueryParameters type to turn signature values in to query parameres or to parse query parameters.
To generate a SAS, you must use the SharedKeyCredential type.
Credentials
When creating a request pipeline, you must specify one of this package's credential types.
- Call the NewAnonymousCredential function for requests that contain a Shared Access Signature (SAS) or for requests to public resources.
- Call the NewSharedKeyCredential function (with an account name & key) to access any and all account resources. You must also use this
to generate Shared Access Signatures.
HTTP Request Policy Factories
This package defines several request policy factories for use with the pipeline package.
Most applications will not use these factories directly; instead, the NewPipeline
function creates the these factories, initializes them (via the PipelineOptions type)
and returns a pipeline object for use by the XxxURL objects.
However, for advanced scenarios, developers can access these policy factory directly
and even create their own and then construct their own pipeline in order to affect HTTP
requests and responses performed by the XxxURL objects. For example, developers can
introduce their own logging, random failures, request recording & playback for fast
testing, HTTP request pacing, alternate retry mechanisms, metering, metrics, etc. The
possibilities are endless!
Below are the request pipeline policy factory functions that are provided with this
package:
- NewRetryPolicyFactory Enables rich retry semantics for failed HTTP requests
- NewRequestLogPolicyFactory Enables rich logging support for HTTP requests/responses & failures
- NewTelemetryPolicyFactory Enables simple modification of the HTTP request's User-Agent header so each request reports the SDK version & language/runtime making the requests
- NewUniqueRequestIDPolicyFactory Adds a x-ms-client-request-id header with a unique UUID value to an HTTP request to help with diagnosing failures
Also, note that all the NewXxxCredential functions return request policy factory objects which get injected into the pipeline.

However, for advanced scenarios, developers can access these policy factories directly
and even create their own and then construct their own pipeline in order to affect HTTP
requests and responses performed by the XxxURL objects. For example, developers can
introduce their own logging, random failures, request recording & playback for fast
testing, HTTP request pacing, alternate retry mechanisms, metering, metrics, etc. The
possibilities are endless!
Below are the request pipeline policy factory functions that are provided with this
package:
- NewRetryPolicyFactory Enables rich retry semantics for failed HTTP requests.
- NewRequestLogPolicyFactory Enables rich logging support for HTTP requests/responses & failures.
- NewTelemetryPolicyFactory Enables simple modification of the HTTP request's User-Agent header so each request reports the SDK version & language/runtime making the requests.
- NewUniqueRequestIDPolicyFactory Adds a x-ms-client-request-id header with a unique UUID value to an HTTP request to help with diagnosing failures.
Also, note that all the NewXxxCredential functions return request policy factory objects which get injected into the pipeline.
