Authenticate Azure Storage REST requests with account-key Shared Key signing.
Chilkat.AuthAzureStorage is a credential object for Azure
Storage Services authentication. It stores the storage account name, Base64
account access key, Azure Storage service type, authentication scheme, and
x-ms-version API version used when signing REST requests for
Blob, Queue, File, or Table storage.
Azure Storage credentials
Shared Key signing
SharedKey or
SharedKeyLite, depending on the service and request style.
Service targeting
Blob, Queue, File, or
Table.
API version header
x-ms-version value required by the Azure Storage
REST API version being used.
REST integration
Chilkat.Rest so requests are
signed automatically before being sent.
Low-level control
AuthAzureStorage object, set the storage
Account, Base64 AccessKey, Service,
Scheme, and XMsVersion, then attach it to a
Chilkat.Rest request workflow. Use
AuthAzureStorage for Shared Key authorization headers; use
Chilkat.AuthAzureSAS when the request should be authorized with
a SAS query token instead.
Object Creation
// npm install @chilkat/react-native react-native-nitro-modules
// (React Native 0.76+ with the New Architecture; then `pod install` for iOS. The Chilkat
// native library is downloaded and verified during the native build -- see the package README.)
import { Chilkat, AuthAzureStorage } from '@chilkat/react-native'
// Once per app start, before any other Chilkat call:
Chilkat.unlockBundle('Anything for 30-day trial') // shorthand for new Global().unlockBundle(..)
const authAzureStorage = new AuthAzureStorage()
// ... the native object is released when `authAzureStorage` is garbage collected, or now with authAzureStorage.dispose()Creates the underlying native Chilkat object. AuthAzureStorage is a Nitro Module HybridObject: use it from the JavaScript thread only (it cannot be passed to a Worklet or another runtime). Every member is synchronous and blocks the JavaScript thread until Chilkat returns; a method that can take a while also exists as a ...Async twin returning a Promise, which runs the same call on a native worker thread so the UI keeps rendering. While such a call is pending, every other call on this object throws, except abort() and assigning onPercentDone / onProgressInfo.
Releases the native object immediately instead of waiting for garbage collection (useful for a large BinData or an open socket). Calling it more than once is harmless; any other use of the object afterwards throws. An object with a pending ...Async call cannot be disposed until the promise settles.
Errors
A method that can fail throws a plain Error: a method whose only outcome is success or failure returns void and throws on failure; a method producing a string or an object returns it and throws where Chilkat would have returned null. The error's message is "Class.method(...): reason", where the reason is the last informative line of the object's lastErrorText, which holds the full Chilkat log of the failed call. A ...Async twin rejects its promise with the same Error instead of throwing. Properties never throw, and methods that answer a question (has..., is..., ...) return a plain boolean.
try {
authAzureStorage.someMethod(...)
} catch (e) {
console.log((e as Error).message) // AuthAzureStorage.someMethod(...): <reason>
console.log(authAzureStorage.lastErrorText) // the full Chilkat log of the failed call
}
// The same call without blocking the JavaScript thread:
try {
await authAzureStorage.someMethodAsync(...)
} catch (e) {
console.log((e as Error).message) // AuthAzureStorage.someMethodAsync: <reason>
}
Properties
AccessKey
accessKey: string
Account
account: string
The Azure storage account name. (A storage account can contain zero or more containers. A container contains properties, metadata, and zero or more blobs. A blob is any single entity comprised of binary data, properties, and metadata. )
topDebugLogFilePath
debugLogFilePath: string
If set to a file path, this property logs the LastErrorText of each Chilkat method or property call to the specified file. This logging helps identify the context and history of Chilkat calls leading up to any crash or hang, aiding in debugging.
Enabling the VerboseLogging property provides more detailed information. This property is mainly used for debugging rare instances where a Chilkat method call causes a hang or crash, which should generally not happen.
Possible causes of hangs include:
- A timeout property set to 0, indicating an infinite timeout.
- A hang occurring within an event callback in the application code.
- An internal bug in the Chilkat code causing the hang.
LastErrorHtml
readonly lastErrorHtml: string
Provides HTML-formatted information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.
topLastErrorText
readonly lastErrorText: string
Provides plain text information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.
LastErrorXml
readonly lastErrorXml: string
Provides XML-formatted information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.
topLastMethodSuccess
lastMethodSuccess: boolean
Indicates the success or failure of the most recent method call: true means success, false means failure. This property remains unchanged by property setters or getters. This method is present to address challenges in checking for null or Nothing returns in certain programming languages. Note: This property does not apply to methods that return integer values or to boolean-returning methods where the boolean does not indicate success or failure.
Scheme
scheme: string
Can be SharedKey or SharedKeyLite. The default value is SharedKey.
Service
service: string
Can be Blob, Queue, File, or Table. The default is Blob.
Note: Authentication for the Table service did not work in versions prior to v9.5.0.83.
VerboseLogging
verboseLogging: boolean
If set to true, then the contents of LastErrorText (or LastErrorXml, or LastErrorHtml) may contain more verbose information. The default value is false. Verbose logging should only be used for debugging. The potentially large quantity of logged information may adversely affect peformance.
Version
readonly version: string
XMsVersion
xMsVersion: string
If set, automatically adds the x-ms-version HTTP request header to Azure Storage requests. The default value is 2014-02-14.
