Java selenium 基本使用

此功能是抓取本地文件里面的数据，然后填充到web应用上的指定输入框

1.首先下载 msedgedriver

2 其次获取Xpath

3.配置selenium 仓库地址

package com.example.automation; import org.openqa.selenium.*; import org.openqa.selenium.edge.EdgeDriver; import java.io.*; public class WorkOrderAutomation { public static void main(String[] args) throws InterruptedException, IOException { System.setProperty("webdriver.edge.driver", "C:\\Windows\\System32\\msedgedriver.exe"); WebDriver driver = new EdgeDriver(); driver.get("http://localhost:3000/workorder/workorder"); Thread.sleep(20000); String myXPath ="//input[@placeholder='请输入工单名称']"; BufferedReader reader = new BufferedReader(new FileReader("C:\\Users\\zhihu.wang\\Desktop\\LotSN.txt")); String data; while((data = reader.readLine()) != null){ try { //查找元素 WebElement element = driver.findElement(By.xpath(myXPath)); element.clear(); //输入值 element.sendKeys(reader.readLine()); //回车 element.sendKeys(Keys.RETURN); //延迟2秒 Thread.sleep(2000); } catch (Exception e) { System.out.println("错误：" + e.getMessage()); } } //等待五秒关闭浏览器 Thread.sleep(5000); driver.quit(); } }

4.有时候复制的Xpath不准，需要在浏览器控制台运行下面代码获取Xpath。

// 查找所有非隐藏输入框
var inputs = Array.from(document.querySelectorAll('input:not([type="hidden"])'));
inputs.forEach((input, index) => {
console.log(`[${index+1}]`, {
placeholder: input.placeholder,
id: input.id,
name: input.name,
class: input.className,
type: input.type
});
});
