Question

有时在致电driver.get(feedUrl)后，driver.getCurrentUrl()会返回上一个网址。这是为什么？

代码提取：

while((feedItem = sharedQueue.poll()) != null){
    final String feedUrl = feedItem.getLink();

    logger.info("Driver getting " + feedUrl);
    driver.get(feedUrl);

    final String url = driver.getCurrentUrl();
    logger.info("Driver got feedUrl: " + feedUrl + " from driverUrl: " + url );
}

日志提取：

如您所见，最后一个日志条目具有正确的feedUrl，但是之前的driverUrl

Answer 1

要等待页面加载，您可以明确等待JavascriptExecutor事务执行，

((JavascriptExecutor) myDriver).executeScript("return document.readyState").equals("complete")

Answer 2

您需要等待driver.get完成加载。您可以使用不同的等待技术 - 称为隐式和显式等待。

见这里：http://www.seleniumhq.org/docs/04_webdriver_advanced.jsp

我个人会使用显式等待：

self.tree.tag_bind(childID, '<Double-1>', jclass.tree_func)

获得后Selenium getCurrentUrl不会改变
