java - 如何使用 Applescript 或 Java 检查 Mac 上安装的 Adob​​e flash Player？

Question

我正在尝试以编程方式安装 Adob​​eFlashPlayer，在此之前我需要检查它是否已经安装？如果是，那么我需要获取相同的版本。由于 Flash Player 将作为插件添加，我需要在 Safari 和 Firefox 浏览器中检查相同的内容。请建议如何使用 Applescripts 实现相同的效果(如果可能，不使用 SWFObjects)。

Answer 1

在 Mac 上，浏览器插件安装在名为“Internet Plug-Ins”的文件夹中。您可以将此文件夹放在用户的 Libray 文件夹或主 Library 文件夹中。所以使用 applescript 我们可以检查这些文件夹...

set pluginName to "Flash Player.plugin"
set pluginsMainFolder to (path to library folder from local domain as text) & "Internet Plug-Ins:"
set pluginsUserFolder to (path to library folder from user domain as text) & "Internet Plug-Ins:"

-- check the folders and get the version if found
set theVersion to missing value
tell application "System Events"
    try
        set f to first file of folder pluginsMainFolder whose name is pluginName
        set theVersion to short version of f
    end try
    if theVersion is missing value then
        try
            set f to first file of folder pluginsUserFolder whose name is pluginName
            set theVersion to short version of f
        end try
    end if
end tell

if theVersion is missing value then
    display dialog pluginName & " is not installed!"
else
    display dialog pluginName & " is installed!" & return & "Version: " & theVersion
end if
