如何使用C#Selenium从谷歌搜索中获取所有url(仅限第一页)，然后从该列表中获取指定url的索引

Question

嘿，在C#中使用Selenium并使用NUnit测试和chrome的家伙们，我如何从谷歌搜索的第一页获取列表中的所有主要URL(web URL(，然后从该列表中获取指定URL的索引号？

Answer 1

我不确定你是如何知道你想搜索什么url的，但它就在这里。我添加了一个dictionary方法，以防你想存储索引和url以备将来使用。

using NUnit.Framework;
using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;
using System;
using System.Collections.Generic;
using System.Linq;
namespace Selenium
{
public class Tests
{
public IWebDriver driver;

[SetUp]
public void Setup()
{
driver = new ChromeDriver(".");
}
[Test]
public void TestUrlsIndex()
{
driver.Navigate().GoToUrl("https://google.com");
//accept privacy
driver.FindElement(By.XPath("//div[text()='I agree']")).Click();
//type something and press Enter
driver.FindElement(By.Name("q")).SendKeys("Retrieve Index" + Keys.Enter);
//get all a elements 
var a_webElements = driver.FindElements(By.XPath("//div[@class='g']/div/div/a"));

//print the index for all
for (int i = 0; i < a_webElements.Count; i++)
{
Console.WriteLine($"The index is {i} for the url {a_webElements[i].GetAttribute("href")}");
}
//when you know the url and want to return its index
var index = ReturnIndexOfAnUrl(a_webElements, "https://stackoverflow.com/questions/41217310/get-index-of-a-row-of-a-pandas-dataframe-as-an-integer");

}
//when you want to search the url and return its index
public int ReturnIndexOfAnUrl(IList<IWebElement> webElements, string searchHref)
{
return webElements.ToList().FindIndex(x => x.GetAttribute("href").Equals(searchHref));
}
//when you want to store the index and its corresponding url
public Dictionary<int, string> ReturnIndexAsIndexAndUrlAsValue(IList<IWebElement> webElements)
{
var dictionary = new Dictionary<int, string>();
for (int i = 0; i < webElements.Count; i++)
{
dictionary.Add(i, webElements[i].GetAttribute("href"));
}
return dictionary;
}

[TearDown]
public void TearDown()
{
driver.Close();
}
}
}
