[Selenium] 操作浏览器 Cookies

时间:2022-05-19 03:37:22

WebDriver 提供了一系列 Cookies 的操作来获取、填写、删除 Cookies 的方法,节省了多次在登陆页面的查找元素并填写登录信息的时间。

1)获取 Cookies ,并保存到文件中以备后续使用

package com.learningselenium.normalwebdriver;

import java.io.BufferedWriter;

import java.io.File;

import java.io.FileWriter;

import java.io.FileReader;

import java.util.Date;

import java.util.StringTokenizer;

import org.openqa.selenium.By;

import org.openqa.selenium.Cookie;

import org.openqa.selenium.Webdriver;

import org.openqa.selenium.firefox.FirefoxDriver;

public class testGetCookies{

  public static void main(String... args){

    WebDriver driver = new FirefoxDriver();

    driver.get("http://zhizhu.com/#signin");

    //填写用户信息,然后登陆

    driver.findElement(By.name("email")).sendKeys("seleniumcookies@126.com");

    driver.findElement(By.name("password").sendKeys("cookies123"));

    if(driver.findElement(By.name("rememberme")).isSelected()){

      driver.findElement(By.name("remermberme")).click();

    }

    driver.findElement(By.className("sign-button")).click();

    

    File cookieFile = new File("zhizhu.cookie.txt");

    try{

      cookieFile.delete();

      cookieFile.createNewFile();

      FileWriter fileWriter = new FileWriter(cookieFile);

      BufferedWriter bufferedWriter = new BufferedWriter(fileWriter);

      for (Cookie cookie : driver.manage().getCookies()){

        bufferedWriter.write((cookie.getName() + ";" + cookie.getDomain() + ";" + cookie.getExpiry() + ";" + cookie.isSecure()));

        bufferedWriter.newLine();

      }

      bufferedWriter.flush();

      bufferedWriter.close();

      fileWriter.close();

    }catch (Exception ex){

      ex.printStackTrace();

    }

    driver.quit();

  }

}

2)读取保存的Cookies 信息并自动填充到新打开的浏览器 Cookies 中,然后直接进入登陆状态后的页面

public class testAddCookies{

  private static BufferedReader bufferedReader;

  public static void main(String... args){

    WebDriver driver = new FirefoxDriver();

    driver.get("http://zhizhu.com/#signin");

    try{

      File cookieFile = new File("zhihu.cookie.txt");

      FileReader fr = new FileReader(cookieFile);

      bufferedReader = new BufferedReader(fr);

      String line;

      while((line = bufferedReader.readLine()) != null){

        StringTokenizer stringTokenizer = new StringTokenizer(line, ";");

        while (stringTokenizer.hasMoreTokens()){

          String name = stringTokenizer.nextToken();

          String value= stringTokenizer.nextToken();

          String domain = stringTokenizer.nextToken();

          String path = stringTokenizer.nextToken();

          Date expiry = null;

          String dt;

          if(! (dt = stringTokenizer.nextToken()).equals("null")){

            expiry = new Date(dt);

          }

          boolean isSecure = new Boolean(stringTokenizer.nextToken()).booleanVaue();

          Cookie cookie = new Cookie(name, value, domain, path, expiry, isSecure);

        }

      }

    }catch(Exception ex){

      ex.printStackTrace();

    }

    driver.get("http://www.zhihu.com");

}
