Send a REST Request with a Binary Body

See more REST Examples

Demonstrates Rest.FullRequestBd, which sends a complete request whose binary body is read from a BinData and stores the text response body in a StringBuilder.

The file paths are relative to the application's current working directory. Absolute paths may also be used. Supply the paths appropriate to your own environment.

local chilkat = require("chilkat")

local rest = chilkat.Rest.new()
local bTls = true
local bAutoReconnect = true
local success = rest:connect("example.com", 443, bTls, bAutoReconnect)
if not success then
    print(rest.last_error_text)
    return
end

-- may also be used.  Supply the paths appropriate to your own environment.

-- FullRequestBd sends a request whose binary body is read from a BinData and stores the text
-- response body in a StringBuilder.
local bdRequest = chilkat.BinData.new()
local bLoaded = bdRequest:load_file("qa_data/image.png")
if not bLoaded then
    print("Failed to load the request body file.")
    return
end

rest:add_header("Content-Type", "image/png")

local sbResponse = chilkat.StringBuilder.new()
success = rest:full_request_bd("PUT", "/api/images/1", bdRequest, sbResponse)
if not success then
    print(rest.last_error_text)
    return
end

local responseText = sbResponse:get_as_string()
if not sbResponse.last_method_success then
    print(sbResponse.last_error_text)
    return
end

print(responseText)
