1. 获取cookies并保存到文件

步骤：

① 打开CSDN的登录界面；

② 填写用户名和密码；

③ 新建文件txt；

④ 获取cookies，并将cookies保存到先前新建的文件中。

代码：

@Before
    public void Setup(){
        File chromeDriverPath = new File("D:\\Selenium\\webdriver\\chromedriver.exe");
        System.setProperty("webdriver.chrome.driver", chromeDriverPath.getAbsolutePath());
        webDriver = new ChromeDriver();
    }
 
    @Test
    public void writeCookies() {
 
        webDriver.get("https://passport.csdn.net/account/login?from=http://my.csdn.net/my/mycsdn");
        webDriver.findElement(By.xpath("//*[@id=\"username\"]")).sendKeys("用户名");
        webDriver.findElement(By.xpath("//*[@id=\"password\"]")).sendKeys("密码");
 
        if (webDriver.findElement(By.xpath("//*[@id=\"rememberMe\"]")).isSelected()){
            webDriver.findElement(By.xpath("//*[@id=\"rememberMe\"]")).click();
        }
 
        webDriver.findElement(By.xpath("//*[@id=\"fm1\"]/input[6]")).click();
 
        File cookieFile = new File("csdn.cookie.txt");
 
        try {
            cookieFile.delete();
            cookieFile.createNewFile();
            FileWriter fileWriter = new FileWriter(cookieFile);
            BufferedWriter bufferedWriter = new BufferedWriter(fileWriter);
 
            for (Cookie cookie:webDriver.manage().getCookies()){
                bufferedWriter.write((cookie.getName()+";"+
                                      cookie.getValue()+";"+
                                      cookie.getDomain()+";"+
                                      cookie.getPath()+";"+
                                      cookie.getExpiry()+";"+
                                      cookie.isSecure()));
                bufferedWriter.newLine();
            }
            bufferedWriter.flush();
            bufferedWriter.close();
            fileWriter.close();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
 
        webDriver.quit();
    } 

2. 读取先前文件中保存的信息，将信息添加到新建的cookie中，将新建的cookie添加到浏览器中，实现自动登陆。

步骤：

① 打开CSDN界面；

② 从保存的文件中取出登陆的信息，添加到cookie中，将cookie添加到浏览器中；

③ 打开CSDN界面。

代码：

　@Test
    public void getCookies(){
        BufferedReader bufferedReader;
        webDriver.get("https://passport.csdn.net/account/login?from=http://my.csdn.net/my/mycsdn");
 
        try {
            File cookieFile = new File("csdn.cookie.txt");
            FileReader fileReader = new FileReader(cookieFile);
            bufferedReader = new BufferedReader(fileReader);
 
            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()).booleanValue();
                    Cookie cookie = new Cookie(name, value,domain,path,expiry,isSecure);
                    webDriver.manage().addCookie(cookie);
                }
            }
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
 
        webDriver.get("http://blog.csdn.net/");
 
    }
