SendCustomRequest Method

Sends a custom request to the Azure Blob Storage service.

Syntax

void __fastcall SendCustomRequest(String HttpMethod, String Blob, String RequestBody);

Remarks

This method can be used to send arbitrary requests to the Azure Blob Storage service.

Valid values for HttpMethod are:

• GET (default if empty)
• HEAD
• POST
• PUT
• DELETE

The Blob and RequestBody parameters may be empty if not needed.

Usage

When this method is called, the component does the following:

1. Builds a request URL, including query parameters, using the following:
   • UseSSL
   • Account (must be non-empty)
   • Container (if non-empty)
   • Blob (if non-empty)
   • Snapshot (if both it and Blob are non-empty)
   • QueryParam*
2. Adds request headers from:
   • APIVersion
   • LeaseId (if non-empty)
   • IfMatch (if non-empty)
   • OtherHeaders
3. Authenticates the request using Authorization (if non-empty), or AccessKey (in which case the request is signed).
4. Sends the request, including RequestBody if non-empty.
5. Stores the response headers in the ParsedHeader* properties; and the response body in the specified LocalFile, or BlobData (using the same logic as GetBlob).

If the response body is XML data, the XPath, XText, and other X* configuration settings can then be used to navigate and extract information from it.
