driver.current_url

await driver.getCurrentUrl();

driver.currentUrl

1 - 浏览器导航

打开网站

启动浏览器后你要做的第一件事就是打开你的网站。这可以通过一行代码实现:

// 简便的方法
driver.get("https://selenium.dev");

// 更长的方法
driver.navigate().to("https://selenium.dev");

driver.get("https://selenium.dev")

driver.Navigate().GoToUrl(@"https://selenium.dev");

    # 简便的方法
driver.get 'https://selenium.dev'

    # 更长的方法
driver.navigate.to 'https://selenium.dev'

await driver.get('https://selenium.dev');

// 简便的方法
driver.get("https://selenium.dev")

// 更长的方法
driver.navigate().to("https://selenium.dev")

后退

按下浏览器的后退按钮:

driver.navigate().back();

driver.back()

driver.Navigate().Back();

driver.navigate.back

await driver.navigate().back();

driver.navigate().back()

前进

按下浏览器的前进键:

driver.navigate().forward();

driver.forward()

driver.Navigate().Forward();

driver.navigate.forward

await driver.navigate().forward();

driver.navigate().forward()

刷新

刷新当前页面:

driver.navigate().refresh();

driver.refresh()

driver.Navigate().Refresh();

driver.navigate.refresh

await driver.navigate().refresh();

driver.navigate().refresh()

2 - JavaScript 警告框,提示框和确认框

WebDriver提供了一个API, 用于处理JavaScript提供的三种类型的原生弹窗消息. 这些弹窗由浏览器提供限定的样式.

Alerts 警告框

其中最基本的称为警告框, 它显示一条自定义消息, 以及一个用于关闭该警告的按钮, 在大多数浏览器中标记为"确定"(OK). 在大多数浏览器中, 也可以通过按"关闭"(close)按钮将其关闭, 但这始终与“确定”按钮具有相同的作用. 查看样例警告框.

WebDriver可以从弹窗获取文本并接受或关闭这些警告.

//Click the link to activate the alert
driver.findElement(By.linkText("See an example alert")).click();

//Wait for the alert to be displayed and store it in a variable
Alert alert = wait.until(ExpectedConditions.alertIsPresent());

//Store the alert text in a variable
String text = alert.getText();

//Press the OK button
alert.accept();

# Click the link to activate the alert
driver.find_element(By.LINK_TEXT, "See an example alert").click()

# Wait for the alert to be displayed and store it in a variable
alert = wait.until(expected_conditions.alert_is_present())

# Store the alert text in a variable
text = alert.text

# Press the OK button
alert.accept()

//Click the link to activate the alert
driver.FindElement(By.LinkText("See an example alert")).Click();

//Wait for the alert to be displayed and store it in a variable
IAlert alert = wait.Until(ExpectedConditions.AlertIsPresent());

//Store the alert text in a variable
string text = alert.Text;

//Press the OK button
alert.Accept();

# Click the link to activate the alert
driver.find_element(:link_text, 'See an example alert').click

# Store the alert reference in a variable
alert = driver.switch_to.alert

# Store the alert text in a variable
alert_text = alert.text

# Press on OK button
alert.accept

//Click the link to activate the alert
await driver.findElement(By.linkText('See an example alert')).click();

// Wait for the alert to be displayed
await driver.wait(until.alertIsPresent());

// Store the alert in a variable
let alert = await driver.switchTo().alert();

//Store the alert text in a variable
let alertText = await alert.getText();

//Press the OK button
await alert.accept();

// Note: To use await, the above code should be inside an async function

//Click the link to activate the alert
driver.findElement(By.linkText("See an example alert")).click()

//Wait for the alert to be displayed and store it in a variable
val alert = wait.until(ExpectedConditions.alertIsPresent())

//Store the alert text in a variable
val text = alert.getText()

//Press the OK button
alert.accept()

Confirm 确认框

确认框类似于警告框, 不同之处在于用户还可以选择取消消息. 查看样例确认框.

此示例还呈现了警告的另一种实现:

//Click the link to activate the alert
driver.findElement(By.linkText("See a sample confirm")).click();

//Wait for the alert to be displayed
wait.until(ExpectedConditions.alertIsPresent());

//Store the alert in a variable
Alert alert = driver.switchTo().alert();

//Store the alert in a variable for reuse
String text = alert.getText();

//Press the Cancel button
alert.dismiss();

# Click the link to activate the alert
driver.find_element(By.LINK_TEXT, "See a sample confirm").click()

# Wait for the alert to be displayed
wait.until(expected_conditions.alert_is_present())

# Store the alert in a variable for reuse
alert = driver.switch_to.alert

# Store the alert text in a variable
text = alert.text

# Press the Cancel button
alert.dismiss()

//Click the link to activate the alert
driver.FindElement(By.LinkText("See a sample confirm")).Click();

//Wait for the alert to be displayed
wait.Until(ExpectedConditions.AlertIsPresent());

//Store the alert in a variable
IAlert alert = driver.SwitchTo().Alert();

//Store the alert in a variable for reuse
string text = alert.Text;

//Press the Cancel button
alert.Dismiss();

# Click the link to activate the alert
driver.find_element(:link_text, 'See a sample confirm').click

# Store the alert reference in a variable
alert = driver.switch_to.alert

# Store the alert text in a variable
alert_text = alert.text

# Press on Cancel button
alert.dismiss

//Click the link to activate the alert
await driver.findElement(By.linkText('See a sample confirm')).click();

// Wait for the alert to be displayed
await driver.wait(until.alertIsPresent());

// Store the alert in a variable
let alert = await driver.switchTo().alert();

//Store the alert text in a variable
let alertText = await alert.getText();

//Press the Cancel button
await alert.dismiss();

// Note: To use await, the above code should be inside an async function

//Click the link to activate the alert
driver.findElement(By.linkText("See a sample confirm")).click()

//Wait for the alert to be displayed
wait.until(ExpectedConditions.alertIsPresent())

//Store the alert in a variable
val alert = driver.switchTo().alert()

//Store the alert in a variable for reuse
val text = alert.text

//Press the Cancel button
alert.dismiss()

Prompt 提示框

提示框与确认框相似, 不同之处在于它们还包括文本输入. 与处理表单元素类似, 您可以使用WebDriver的sendKeys来填写响应. 这将完全替换占位符文本. 按下取消按钮将不会提交任何文本. 查看样例提示框.

//Click the link to activate the alert
driver.findElement(By.linkText("See a sample prompt")).click();

//Wait for the alert to be displayed and store it in a variable
Alert alert = wait.until(ExpectedConditions.alertIsPresent());

//Type your message
alert.sendKeys("Selenium");

//Press the OK button
alert.accept();

# Click the link to activate the alert
driver.find_element(By.LINK_TEXT, "See a sample prompt").click()

# Wait for the alert to be displayed
wait.until(expected_conditions.alert_is_present())

# Store the alert in a variable for reuse
alert = Alert(driver)

# Type your message
alert.send_keys("Selenium")

# Press the OK button
alert.accept()

//Click the link to activate the alert
driver.FindElement(By.LinkText("See a sample prompt")).Click();

//Wait for the alert to be displayed and store it in a variable
IAlert alert = wait.Until(ExpectedConditions.AlertIsPresent());

//Type your message
alert.SendKeys("Selenium");

//Press the OK button
alert.Accept();

# Click the link to activate the alert
driver.find_element(:link_text, 'See a sample prompt').click

# Store the alert reference in a variable
alert = driver.switch_to.alert

# Type a message
alert.send_keys("selenium")

# Press on Ok button
alert.accept

//Click the link to activate the alert
await driver.findElement(By.linkText('See a sample prompt')).click();

// Wait for the alert to be displayed
await driver.wait(until.alertIsPresent());

// Store the alert in a variable
let alert = await driver.switchTo().alert();

//Type your message
await alert.sendKeys("Selenium");

//Press the OK button
await alert.accept();

//Note: To use await, the above code should be inside an async function

//Click the link to activate the alert
driver.findElement(By.linkText("See a sample prompt")).click()

//Wait for the alert to be displayed and store it in a variable
val alert = wait.until(ExpectedConditions.alertIsPresent())

//Type your message
alert.sendKeys("Selenium")

//Press the OK button
alert.accept()

3 - 同cookies一起工作

Cookie是从网站发送并存储在您的计算机中的一小段数据. Cookies主要用于识别用户并加载存储的信息.

WebDriver API提供了一种使用内置的方法与Cookie进行交互:

这个方法常常用于将cookie添加到当前访问的上下文中. 添加Cookie仅接受一组已定义的可序列化JSON对象. 这里是一个链接, 用于描述可接受的JSON键值的列表

首先, 您需要位于有效Cookie的域上. 如果您在开始与网站进行交互之前尝试预设cookie, 并且您的首页很大或需要一段时间才能加载完毕, 则可以选择在网站上找到一个较小的页面 (通常404页很小, 例如 http://example.com/some404page)

import org.openqa.selenium.*;
import org.openqa.selenium.chrome.ChromeDriver;

public class addCookie {
    public static void main(String[] args) {
        WebDriver driver = new ChromeDriver();
        try {
            driver.get("http://www.example.com");

            // Adds the cookie into current browser context
            driver.manage().addCookie(new Cookie("key", "value"));
        } finally {
            driver.quit();
        }
    }
}

from selenium import webdriver

driver = webdriver.Chrome()

driver.get("http://www.example.com")

# Adds the cookie into current browser context
driver.add_cookie({"name": "key", "value": "value"})

using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;

namespace AddCookie {
 class AddCookie {
  public static void Main(string[] args) {
   IWebDriver driver = new ChromeDriver();
   try {
    // Navigate to Url
    driver.Navigate().GoToUrl("https://example.com");

    // Adds the cookie into current browser context
    driver.Manage().Cookies.AddCookie(new Cookie("key", "value"));
   } finally {
    driver.Quit();
   }
  }
 }
}

require 'selenium-webdriver'
driver = Selenium::WebDriver.for :chrome

begin
  driver.get 'https://www.example.com'
  
  # Adds the cookie into current browser context
  driver.manage.add_cookie(name: "key", value: "value")
ensure
  driver.quit
end


        it('Create a cookie', async function() {
            await driver.get('https://www.selenium.dev/selenium/web/blank.html');

            // set a cookie on the current domain
            await driver.manage().addCookie({ name: 'key', value: 'value' });
