[英]Testing Chrome using Selenium-WebDriver while offline in C#
[英]Error using Selenium Chrome Webdriver with C#
我使用 Selenium Chrome Webdriver 制作了一個程序。 我從一個已知網站上獲取了文本。 當它工作並測試幾天時,它完美無缺。 但是有一天使用相同的代碼運行它時出現此錯誤“System.InvalidOperationException:'會話未創建:此版本的ChromeDriver僅支持Chrome版本83(SessionNotCreated)'”
它說錯誤在這行代碼上: driver = new ChromeDriver(options);
我有來自 Selenium 的最新更新,但 Visual Studio 版本是 Chrome WebDriver 的 83.0.0,而我的 Chrome 版本是 85.0.4183.83。 我該怎么辦?
這是我的代碼:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Net.Http;
using System.Threading.Tasks;
using HtmlAgilityPack;
using System.Security.Cryptography;
using OpenQA.Selenium;
using OpenQA.Selenium.Support.UI;
using OpenQA.Selenium.Chrome;
public static class Program
{
public static void Main()
{
IWebDriver driver;
var options = new ChromeOptions();
options.AddArgument("headless");
options.AddArgument("--disable-gpu");
driver = new ChromeDriver(options);
driver.Navigate().GoToUrl("");
string currentDay = DateTime.Today.DayOfWeek.ToString();
System.Threading.Thread.Sleep(5000);
switch(currentDay)
{
case "Monday":
var MondayFood = driver.FindElement(By.XPath("/html/body/main/article/section[1]/div/div[1]/div[2]/div[2]/div/div/div[1]/ul/li[1]/p[1]/span[2]"));
System.Console.WriteLine(MondayFood.Text);
break;
case "Tuesday":
var TuesdayFood = driver.FindElement(By.XPath("/html/body/main/article/section[1]/div/div[1]/div[2]/div[2]/div/div/div[2]/ul/li[1]/p[1]/span[2]"));
System.Console.WriteLine(TuesdayFood.Text);
break;
case "Wednesday":
var WednesdayFood = driver.FindElement(By.XPath("/html/body/main/article/section[1]/div/div[1]/div[2]/div[2]/div/div/div[3]/ul/li[1]/p[1]/span[2]"));
System.Console.WriteLine(WednesdayFood.Text);
break;
case "Thursday":
var ThursdayFood = driver.FindElement(By.XPath("/html/body/main/article/section[1]/div/div[1]/div[2]/div[2]/div/div/div[4]/ul/li[1]/p[1]/span[2]"));
System.Console.WriteLine(ThursdayFood.Text);
break;
case "Friday":
var FridayFood = driver.FindElement(By.XPath("/html/body/main/article/section[1]/div/div[1]/div[2]/div[2]/div/div/div[5]/ul/li[1]/p[1]/span[2]"));
System.Console.WriteLine(FridayFood.Text);
break;
}
System.Console.ReadLine();
}
}
首先,按照以下說明檢查您的 Chrome 版本:
然后下載匹配的 chrome webdriver 版本。 通過此鏈接: https : //chromedriver.chromium.org/downloads
