See more MedTunnel Examples

Get a specific attachment of a message. The MessageId and AttachmentId are obtained from the "Get Mailbox Messages" example. 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()

-- Implements the following CURL command:

-- curl -X GET -k
--         -H "Authorization:PutAuthorizationTokenHere"
--         https://server.medtunnel.com/medtunnelmsg/api/Message/GetAttachment?messageid=989448&attachmentid=424857&setreadflag=false

-- Use the following online tool to generate HTTP code from a CURL command
-- Convert a cURL Command to HTTP Source Code

http:set_request_header("Authorization", "PutAuthorizationTokenHere")

-- The messageId and attachmentId are contained in the response from reading the mailbox messages.
http:set_url_var("messageId", "989448")
http:set_url_var("attachmentId", "424857")
http:set_url_var("setReadFlag", "false")

-- Download the attachment data into bd.
local bd = chilkat.BinData.new()
local success = http:quick_get_bd("https://server.medtunnel.com/MedTunnelMsg/api/Message/GetAttachment?messageid={$messageId}&attachmentid={$attachmentId}&setreadflag={$setReadFlag}", bd)
if not success then
    print(http.last_error_text)
    return
end

local respStatusCode = http.last_status
print("Response Status Code = " .. respStatusCode)
if respStatusCode >= 400 then
    print("Response Header:")
    print(http.last_header)
    -- For errors, the response body contains an error message instead of the actual attachment data.
    print("Response Body:")
    print(bd:get_string("utf-8"))
    print("Failed.")
    return
end

-- Save the attachment data.
-- The attachment filename is also contained in the response from reading the mailbox messages.
success = bd:write_file("qa_output/starfish.jpg")
if not success then
    print("Failed to save attachment file.")
else
    print("Success.")
