如何从活动的浏览器选项卡获取当前URL？

Question

我正在编写一个应用程序来监控PC上的应用程序使用情况。

到目前为止，我有这段代码：

do {
    char blabla[200];
    memset(blabla, 0, sizeof(blabla));
    GetWindowText(GetForegroundWindow(), blabla, sizeof(blabla));
    std::cout << "Active Window Title: " << blabla << std::endl;
    Sleep(500);
} while (1);

给出如下输出：

Active Window Title: How to get the current URL from an active browser tab? - Stack Overflow - Google Chrome
Active Window Title: How to get the current URL from an active browser tab? - Stack Overflow - Google Chrome
Active Window Title: Meta Stack Overflow - Mozilla Firefox
Active Window Title: Meta Stack Overflow - Mozilla Firefox
Active Window Title: Meta Stack Overflow - Mozilla Firefox
Active Window Title: Upatras1.docx - Microsoft Word
Active Window Title: Upatras1.docx - Microsoft Word
Active Window Title: Upatras1.docx - Microsoft Word
Active Window Title: FreeCell
Active Window Title: FreeCell
Active Window Title: FreeCell

我想要实现的是以某种方式从浏览器中读取和捕获地址栏，因此输出将如下所示：

Active Window Title: How to get the current URL from an active browser tab? - Stack Overflow - Google Chrome
URL: http://stackoverflow.com/questions/ask
Active Window Title: How to get the current URL from an active browser tab? - Stack Overflow - Google Chrome
URL: http://stackoverflow.com/questions/ask
Active Window Title: Meta Stack Overflow - Mozilla Firefox
URL: http://meta.stackoverflow.com
Active Window Title: Meta Stack Overflow - Mozilla Firefox
URL: http://meta.stackoverflow.com
Active Window Title: Meta Stack Overflow - Mozilla Firefox
URL: http://meta.stackoverflow.com
Active Window Title: Upatras1.docx - Microsoft Word
Active Window Title: Upatras1.docx - Microsoft Word
Active Window Title: Upatras1.docx - Microsoft Word
Active Window Title: FreeCell
Active Window Title: FreeCell

我尝试使用SendMessage函数来阅读第一个文本框，如下所示：

memset(blabla, 0, sizeof(blabla));
LONG lResult;
lResult = SendMessage(GetForegroundWindow(), WM_GETTEXT, sizeof(blabla) / sizeof(blabla[0]), (LPARAM)blabla);
printf( "Copied %d characters.  Contents: %s\n", lResult, blabla );

...但这也只是返回窗口标题而不是地址。

有人知道从浏览器中提取此信息的方法吗？
