Azure Storage: Upload Contents of String Variable to Block Blob

See more Azure Cloud Storage Examples

Sample code to upload the contents of a string variable to a block blob in Azure Cloud Storage. This creates the block blob, or replaces an existing block blob.

Note: The maximum size of a block blob created by uploading in a single step is 64MB. For larger files, the upload must be broken up into blocks. There is another Chilkat example for that..

Ruby

require 'chilkat'

success = false

# Azure Blob Service Example: Upload the contents of a string variable to a block blob.
# This creates a new block blob or replaces an existing one in its entirety.
# See also: https://msdn.microsoft.com/en-us/library/azure/dd179451.aspx

# This example requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

rest = Chilkat::CkRest.new()

# Connect to the Azure Storage Blob Service
bTls = true
port = 443
bAutoReconnect = true
# In this example, the storage account name is "chilkat".
success = rest.Connect("chilkat.blob.core.windows.net",port,bTls,bAutoReconnect)
if (success != true)
    print rest.lastErrorText() + "\n";
    exit
end

# Provide Azure Cloud credentials for the REST call.
azAuth = Chilkat::CkAuthAzureStorage.new()
azAuth.put_AccessKey("AZURE_ACCESS_KEY")
# The account name used here should match the 1st part of the domain passed in the call to Connect (above).
azAuth.put_Account("chilkat")
azAuth.put_Scheme("SharedKey")
azAuth.put_Service("Blob")
# This causes the "x-ms-version: 2021-08-06" header to be automatically added.
azAuth.put_XMsVersion("2021-08-06")
success = rest.SetAuthAzureStorage(azAuth)

# Note: The application does not need to explicitly set the following
# headers: Content-Length, x-ms-date, Authorization.  These headers
# are automatically set by Chilkat.

# IMPORTANT: Make sure to set the x-ms-blob-type header:
success = rest.AddHeader("x-ms-blob-type","BlockBlob")

# After uploading, the block blob named helloWorld.txt (in the container named "mycontainer")
# will contain the following string:
blobContents = "Hello World!"

# Note: The maximum size of a block blob created by uploading in a single step is 64MB.  
# For larger files, the upload must be broken up into blocks.  There is another Chilkat example for that..
responseStr = rest.fullRequestString("PUT","/mycontainer/helloWorld.txt",blobContents)
if (rest.get_LastMethodSuccess() != true)
    print rest.lastErrorText() + "\n";
    exit
end

# When successful, the Azure Storage service will respond with a 201 response status code,
# with no response body.

if (rest.get_ResponseStatusCode() != 201)
    # Examine the request/response to see what happened.
    print "response status code = " + rest.get_ResponseStatusCode().to_s() + "\n";
    print "response status text = " + rest.responseStatusText() + "\n";
    print "response header: " + rest.responseHeader() + "\n";
    print "response body (if any): " + responseStr + "\n";
    print "---" + "\n";
    print "LastRequestStartLine: " + rest.lastRequestStartLine() + "\n";
    print "LastRequestHeader: " + rest.lastRequestHeader() + "\n";
    exit
end

print "Success." + "\n";
