Lua

QuickGetBd Example

The QuickGetBd method is called to send a GET request to download a binary target, such as PDF, zip, image file, etc. into a Chilkat BinData object. Lua

local chilkat = require("chilkat")

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

local http = chilkat.Http.new()
http.keep_response_body = true

local bd = chilkat.BinData.new()

-- Download the contents of a PDF file into the bd object.
local success = http:quick_get_bd("https://www.chilkatsoft.com/hello.pdf", bd)
if not success then
    -- This will happen if the response status code was 400 or greater,
    -- or if the request could not be sent, or if no response was received.
    --
    -- In other words, success will only be true if bd contains the desired content at the URL (not an error response).
    local statusCode = http.last_status
    print("Response status: " .. statusCode)

    if statusCode == 0 then
        -- There was an error in communications.
        print(http.last_error_text)
    else
        -- We received a response status code indicating failure.
        -- Examine the response body.
        print(http.last_response_body)
    end

    return
end

-- Load the downloaded PDF into a Chilkat PDF object.
local pdf = chilkat.Pdf.new()
success = pdf:load_bd(bd)
if not success then
    print(pdf.last_error_text)
    return
end

-- ...

print("Success.")
