## Java爬虫第二篇：模拟登录CSDN ##

### 概述 ###

本章讲解模拟登录CSDN。  
由于CSDN登录页面加入扫码登录，不能直接获取到账号登录页面，因此需要在页面执行动作，切换到账号登录操作。

### 1. selenium maven配置 ###

<dependency>
                <groupId>org.seleniumhq.selenium</groupId>
                <artifactId>selenium-java</artifactId>
                <version>3.13.0</version>
            </dependency>
    
            <dependency>
                <groupId>org.seleniumhq.selenium</groupId>
                <artifactId>selenium-server</artifactId>
                <version>3.13.0</version>
            </dependency>

### 2. chromedriver 本地路径配置 ###

public class SeleniumUtil {
    	public final static String CHROMEDRIVERPATH = "D://soft//chromedriver.exe";
    	
    	public static void sleep(int m) {
            try {
                Thread.sleep(m);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
        
    }

### 3. 测试 ###

public class Test{
    	public static void main(String[] args) {
    		String username = "xxxx@163.com";
            String password = "***********";
            String url = "https://passport.csdn.net/login";
            System.setProperty("webdriver.chrome.driver", SeleniumUtil.CHROMEDRIVERPATH );// chromedriver localPath
            ChromeOptions chromeOptions = new ChromeOptions();
            chromeOptions.addArguments("–no-sandbox");  //--start-maximized
            WebDriver driver = new ChromeDriver(chromeOptions);
    
            driver.get(url);
            SeleniumUtil.sleep(1000);
            WebElement mainSelectE = driver.findElement(By.cssSelector(".main-select"));
            List<WebElement> loginType = mainSelectE.findElements(By.tagName("a"));
            bgm:for (int i = 0; i < loginType.size(); i++) {
                WebElement aelement = loginType.get(i);
                if( aelement.getText().indexOf("帐号登录") != -1){
                    aelement.click();
                    System.out.println("切换到帐号登录....");
                    break bgm;
                }
            }
            System.out.println("继续操作....");
            SeleniumUtil.sleep(1000);
            WebElement formE = driver.findElement(By.cssSelector("form"));
            WebElement nameE = formE.findElement(By.id("all"));
            WebElement passwordE = formE.findElement(By.id("password"));
            nameE.sendKeys(username);
            formE.findElement(By.id("password-number")).sendKeys(password);
            formE.findElement(By.cssSelector("button")).click();
    
            System.out.println(driver.manage().getCookies());
    	}
    }
