WebDriver：PhantomJSDriver 和保存文件对话框

Question

研究 C# 的 PhantomJSDriver。我发现了一个问题：当我尝试单击调用文件保存对话框的元素时 - PhantomJSDriver 抛出异常：

Error Message => '点击成功但加载失败。状态：'失败''

由 Request => {"headers":{"Accept":"application/json, image/png","Connection":"关闭","Content-Length":"0","Content-Type":"application/json;charset=utf-8","Host":"localhost:34660" },"httpVersion":"1.1","method":"POST","post":"","url":"/click","urlParsed":{"anchor":"","query": "","file":"click","directory":"/","path":"/click","re​​lative":"/click","port":"","host":"" ,"password":"","user":"","userInfo":"","authority":"","protocol":"","source":"/click","queryKey":{ },"chunks":["click"]},"urlOriginal":"/session/8839b140-08d7-11e3-9482-fda3a2d41a6f/element/%3Awdc%3A1376920756991/click"}

PhantomJSDriver 有什么选项可以处理文件保存吗？

C#代码：

var dr = new PhantomJSDriver();

dr.Navigate().GoToUrl("http://www.mywebapps.com/Default.aspx");

var link = dr.FindElementByXPath("//a[@href='Setup.exe']");

link.Click();

Answer 1

PhantomJS 报告点击失败，因为它正在检查页面内容是否有效。在这种情况下，由于您单击的是要下载的 .exe 链接，它会报告单击失败。

如果您想下载文件，而不是点击链接，使用WebClient 直接从 URL 下载。

using (WebClient webClient= new WebClient())
{
    webClient.DownloadFile("http://yoururl/Setup.exe", "c:/temp/setup.exe");
}

你应该阅读这篇博文How to Download Files With Selenium And Why You Shouldn't，如果它没有说服你，它确实提供了一些关于如何完成文件下载的非常好的代码示例。
