Delphi DLL

Example: Http.HttpBd method

Shows how to use the HttpBd method to send an HTTP POST request with the contents of a BinData as the request body. The example sends the following request:

POST /api/v1/sites/123/deploys HTTP/1.1
Host: example.com
Accept: */*
Accept-Encoding: gzip
Content-Type: application/zip
Content-Length: 123456

[binary data bytes of the BinData]
