Download file from a URL using AutoIt, and run in Robot Framework. (Also can use in other application)

What need to figure out?

1.Pass Download URL from Robot Framework to AutoIt.

2.Return File Save Path from AutoIt to Robot Framework.

Step 1: Write AutoIt Script in Notepad++, save as downloadFileFromURL.au3

#include <InetConstants.au3>

#include <MsgBoxConstants.au3>

#include <WinAPIFiles.au3>

; Download a file in the background.

; Wait for the download to complete.

Local $FileDownloadURL = $CmdLine[1]

;Local $FileDownloadURL = "https://test.com/installer.exe"

Local $FileSavePath = @TempDir & "awsinstaller.exe"

; Download the file by waiting for it to complete. The option of 'get the file from the local cache' has been selected.

Local $iBytesSize = InetGet($FileDownloadURL, $FileSavePath, $INET_FORCERELOAD)

; Retrieve the filesize.

Local $iFileSize = FileGetSize($FileSavePath)

; Return with file save path

ConsoleWrite($FileSavePath)

Step 2: Right Click downloadFileFromURL.au3 , select Compile Script in the list.

downloadFileFromURL.au3 will be compiled to an exe.

Step 3: Call downloadFileFromURL.exe in Robot Framework.

${fileURL} Set Variable https://test.com/installer.exe

${exePath} Set Variable D:\Tool\downloadFileFromURL.exe

${result} Run Process ${exePath} ${fileURL}

log ${result.stdout}

Pass parameter from Robot Framework to AutoIt.

Use CmdLine provided by AutoIt

$CmdLine[0] ; Contains the total number of items in the array. $CmdLine[1] ; The first parameter. $CmdLine[2] ; The second parameter. ... $CmdLine[nth] ; The nth parameter e.g. 10 if the array contains 10 items.

Return Value from AutoIt to Robot Framework.

1.Use AutoIt's ConsoleWrite ,write value to stdout

2.Use ${result.stdout} returned by Robot Framework's Run Process , read value from stdout

 Compile AutoIt Script to exe

 Run exe in Robot Framework

为了增加稳定性，做了一下改进。

之前是通过IE浏览器打开安装的URL，很不稳定，改成使用AutoIt进行下载并启动安装.

附上完整的AutoIt脚本和Robot Framework脚本。

downloadFileFromURL.au3

#include <InetConstants.au3>
#include <MsgBoxConstants.au3>
#include <WinAPIFiles.au3>

; Download a file in the background.
; Wait for the download to complete.

;Local $FileDownloadURL = "https://test.com/installer.exe"
Local $FileDownloadURL = $CmdLine[1]
Local $FileName = $CmdLine[2]

Local $FileSavePath = @TempDir & "" & $FileName

; Download the file by waiting for it to complete. The option of 'get the file from the local cache' has been selected.
Local $iBytesSize = InetGet($FileDownloadURL, $FileSavePath, $INET_FORCERELOAD)

; Retrieve the filesize.
Local $iFileSize = FileGetSize($FileSavePath)

; Return with file save path
ConsoleWrite($FileSavePath)
