c# – Selenium driver.Url vs. driver.Navigate().GoToUrl()

前端之家收集整理的这篇文章主要介绍了c# – Selenium driver.Url vs. driver.Navigate().GoToUrl()前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
@H_301_1@哪个是打开Url的首选方法(和之间有什么区别):
driver.Url = "http://example.com";

要么

driver.Navigate().GoToUrl("http://example.com");

另外,如果驱动程序已经指向同一页面,那么会再次设置网址导致页面刷新?

...
driver.Url = "http://example.com";
driver.Url = "http://example.com"; //does this reload the page?
...

FWIW我正在使用Chrome驱动程序chromedriver.exe,但它似乎不是一个托管程序集(我尝试用ILSpy打开它,但没有运气).

解决方法

Selenium是一个开源框架,所以请看源码 here.

GoToUrl()在RemoteNavigator.cs中定义:

/// <summary>
/// Navigate to a url for your test
/// </summary>
/// <param name="url">String of where you want the browser to go to</param>
public void GoToUrl(string url)
{
    this.driver.Url = url;
}

/// <summary>
/// Navigate to a url for your test
/// </summary>
/// <param name="url">Uri object of where you want the browser to go to</param>
public void GoToUrl(Uri url)
{
    if (url == null)
    {
        throw new ArgumentNullException("url","URL cannot be null.");
    }

    this.driver.Url = url.ToString();
}

所以基本上是driver.Navigate().GoToUrl();设置driver.Url在引擎盖下,我没有看到差异.

然而,Driver.Navigate().GoToUrl()更灵活,它允许发送字符串或Uri作为参数类型,而只有字符串才允许通过driver.Url进行设置.

对于你的第二个问题,源代码显示driver.Navigate().Refresh()要求浏览器刷新,而driver.Url告诉浏览器导航.所以这两个根本不同.详情请参阅Difference between Refresh and Navigate function in browser control?

如果要刷新页面,请使用driver.Navigate().Refresh();

Refresh()在RemoteNavigator.cs中定义:

/// <summary>
/// Refresh the browser
/// </summary>
public void Refresh()
{
    // driver.SwitchTo().DefaultContent();
    this.driver.InternalExecute(DriverCommand.Refresh,null);
}

driver.Url定义在RemoteWebDriver.cs

public string Url
{
    ...

    set
    {
        ...

        try
        {
            this.Execute(DriverCommand.Get,parameters);
        }
        ...
    }
}
