在AppleScript中检测Safari私人浏览 [英] Detect Safari Private Browsing in AppleScript

问题描述

我正在尝试编写AppleScript，它可以告诉 Safari的窗口是否处于私有模式.这是在Chrome中执行此操作的AppleScript:

I'm trying to write AppleScript which would tell whether a window of Safari is in private mode. Here is the AppleScript to do so in Chrome:

tell application "Google Chrome"
    set incognitoIsRunning to the (count of (get every window whose mode is "incognito")) is greater than 0
end tell

if (incognitoIsRunning) then
    return "-- PRIVATE MODE --"
end tell

查看是否已选中私人浏览菜单"选项的旧解决方案不再起作用.

The old solution to see whether private browsing menu option is checked no longer works.

推荐答案

Safari中有一个古怪现象，可以利用它来确定是否启用了私有模式:Safari不允许在私有模式下使用localStorage.setItem(请参阅). 相关的StackOverflow帖子) .我们可以通过在AppleScript中使用JavaScript片段来利用这一优势.如果不支持localStorage，则JavaScript会引发错误(由try/catch块捕获)，我们可以使用该错误来设置布尔值.

There is a quirk in Safari that can be exploited to determine whether private mode is enabled: Safari does not allow localStorage.setItem to be used in private mode (see related StackOverflow post). We can take advantage of this by using a snippet of JavaScript from within AppleScript. If localStorage is not supported, the JavaScript throws an error (caught by the try/catch block), which we use to set our boolean.

tell application "Safari"
    set checkMode to "
         var isprivate = false;
          try {
               window.localStorage.setItem('foobar', 1);
          } catch(e) {
               isprivate = true;
          }
       isprivate;
"
    set isPrivate to do JavaScript checkMode in current tab of first window
end tell

log isPrivate

当然，您需要调整此AppleScript才能在Safari中设置适当的目标窗口/标签.

Of course you will need to adjust this AppleScript to set the appropriate target window/tab within Safari.
