JAVA crawler realizes automatic login to Taobao_java
给大家分享一个关于JAVA爬虫的相关知识点,通过代码实现自动登录淘宝网,有兴趣的朋友测试下。
目的
想通过JAVA代码实现淘宝网的自动登录,通过获取设置的登录信息自动填写并提交。目前这个代码是小编测试过的,可以通过,后期不知道淘宝会不会有相应的封堵策略。
代码分享:
package util; import org.openqa.selenium.By; import org.openqa.selenium.WebElement; import org.openqa.selenium.firefox.FirefoxDriver; import org.openqa.selenium.firefox.FirefoxOptions; import org.openqa.selenium.firefox.FirefoxProfile; import java.io.File; import java.util.Random; public class TestCase2 { public static void main(String[] args) { System.setProperty("webdriver.firefox.bin","C:\\Program Files\\Mozilla Firefox\\firefox.exe"); System.setProperty("webdriver.gecko.driver","C:\\Users\\18431\\IdeaProjects\\SeleniumDemo\\bin\\geckodriver.exe"); FirefoxOptions options = new FirefoxOptions(); FirefoxProfile profile = new FirefoxProfile(new File("C:\\Users\\18431\\AppData\\Roaming\\Mozilla\\Firefox\\Profiles\\efzu2oem.default")); options.setProfile(profile); FirefoxDriver driver = new FirefoxDriver(); driver.get("https://login.m.taobao.com/login.htm"); //下面开始完全模拟正常人的操作,所以你会看到很多 sleep 操作 WebElement usernameElement = driver.findElement(By.id("username")); //模拟用户点击用户名输入框 usernameElement.click(); String username = "18588260144";//你的手机号 String password = "xxxxxxxxxxx";//你的密码 Random rand = new Random(); try { for (int i = 0; i <username.length() ; i++) { Thread.sleep(rand.nextInt(1000));//随机睡眠0-1秒 //逐个输入单个字符 usernameElement.sendKeys(""+username.charAt(i)); } WebElement passwordElement = driver.findElement(By.id("password")); passwordElement.click(); //输入完成用户名后,随机睡眠0-3秒 Thread.sleep(rand.nextInt(3000)); for (int i = 0; i <password.length() ; i++) { Thread.sleep(rand.nextInt(1000)); passwordElement.sendKeys(""+password.charAt(i)); } driver.findElement(By.id("btn-submit")).click(); } catch (Exception e){ e.printStackTrace(); } try { Thread.sleep(300000); }catch (InterruptedException ie){ ie.printStackTrace(); } driver.quit(); } }
总结
可以看出来,万变不离其宗,再难的模拟登录都是可以完全模拟人类的操作习惯去实现反爬虫的,好吧,全都告诉你了,PHP 爬虫技术不打算继续写下去了,感觉还是用 PHP 适合它做的事情比较好,PHP 写的爬虫段位太低,还是python 和 java 更好些。

Java 8 introduces the Stream API, providing a powerful and expressive way to process data collections. However, a common question when using Stream is: How to break or return from a forEach operation? Traditional loops allow for early interruption or return, but Stream's forEach method does not directly support this method. This article will explain the reasons and explore alternative methods for implementing premature termination in Stream processing systems. Further reading: Java Stream API improvements Understand Stream forEach The forEach method is a terminal operation that performs one operation on each element in the Stream. Its design intention is

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7

PHP and Python each have their own advantages, and the choice should be based on project requirements. 1.PHP is suitable for web development, with simple syntax and high execution efficiency. 2. Python is suitable for data science and machine learning, with concise syntax and rich libraries.

PHP is suitable for web development, especially in rapid development and processing dynamic content, but is not good at data science and enterprise-level applications. Compared with Python, PHP has more advantages in web development, but is not as good as Python in the field of data science; compared with Java, PHP performs worse in enterprise-level applications, but is more flexible in web development; compared with JavaScript, PHP is more concise in back-end development, but is not as good as JavaScript in front-end development.

PHP and Python each have their own advantages and are suitable for different scenarios. 1.PHP is suitable for web development and provides built-in web servers and rich function libraries. 2. Python is suitable for data science and machine learning, with concise syntax and a powerful standard library. When choosing, it should be decided based on project requirements.
