C# 使用PhantomJS下载文件,c#,selenium,webdriver,phantomjs,C#,Selenium,Webdriver,Phantomjs,我试图使用PhantomJS下载一个文件,但是当我点击下载时,没有下载任何文件,我读到PhantomJS不支持下载,但我需要它,你能帮我吗 以下是我尝试下载时部分的代码: try { checkbox = wait.Until(ExpectedConditions.PresenceOfAllElementsLocatedBy(By.XPath("//form[@id='formDownload']//table[@class='fileTables']//tbody//tr//td//inp

我试图使用
PhantomJS
下载一个文件,但是当我点击下载时,没有下载任何文件,我读到
PhantomJS
不支持下载,但我需要它,你能帮我吗

以下是我尝试下载时部分的代码:

try
{
  checkbox = wait.Until(ExpectedConditions.PresenceOfAllElementsLocatedBy(By.XPath("//form[@id='formDownload']//table[@class='fileTables']//tbody//tr//td//input[@class='checkbox']")));      
  checkbox[countLine - 1].Click();      
  wait.Until(ExpectedConditions.ElementExists(By.Id("all"))).Click();
}
catch (Exception ex)
{
   throw new Exception(ex.Message);
}

好的,您需要做的是:

  • 在html中单击该文件时,需要找到该文件的链接

  • 您需要获取链接并进行httpRequest以获取文件

  • 这是请求的全部功能(我为您提供了一个简单的链接)

    公共静态bool下载文件(字符串url,IWebDriver驱动程序)
    {
    尝试
    {
    //构造HTTP请求以获取文件
    HttpWebRequest httpRequest=(HttpWebRequest)WebRequest.Create(url);
    httpRequest.CookieContainer=new System.Net.CookieContainer();
    对于(int i=0;i
    如果下载依赖于会话(cookie)-怎么办?你可以看到我在我的函数中处理cookie,phantomJS拥有你需要的所有cookie。我会的,我在一个显示文件链接的网站上测试了这个功能,它工作了,所以我知道它工作了,现在我只需要找到这个链接,非常感谢您的关注。我正在使用WebClient,遇到了一些问题,但是添加UserAgent头对我来说完全不同。没想到。。。谢谢
