selenium-java问题解决

确定浏览器和驱动的大版本一致

我的：
浏览器版本： 126.0.6478.57
驱动版本： 126.0.6478.55

设置允许跨域

可以看到控制台提示：Only local connections are allowed.
代码添加：
options.addArguments("--remote-allow-origins=*");
可解决如下报错：

警告: Invalid Status code=403 text=Forbidden
java.io.IOException: Invalid Status code=403 text=Forbidden

Driver info: driver.version: ChromeDriver

maven依赖版本别太高或太低

我使用4.10.0没问题

使用较高版本4.21.0时会报错：

信息: Detected dialect: W3C
Exception in thread "main" java.lang.UnsupportedClassVersionError: org/openqa/selenium/devtools/v123/v123CdpInfo has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0

使用较低版本3.141.59会报错：

Exception in thread "main" java.lang.NoSuchMethodError: com.google.common.collect.ImmutableMap.of(Ljava/lang/Object;Ljava/lang/Object;Ljava/lang/Object;Ljava/lang/Object;Ljava/lang/Object;Ljava/lang/Object;Ljava/lang/Object;Ljava/lang/Object;Ljava/lang/Object;Ljava/lang/Object;Ljava/lang/Object;Ljava/lang/Object;)Lcom/google/common/collect/ImmutableMap;

selenium-java实现后端简单截图代码参考

public static void snapshotBySelenium(String url) {
        // 根据系统来添加不同的驱动路径
        String os = System.getProperty("os.name");
        if (StrUtil.containsIgnoreCase(os, "windows")) {
            System.setProperty("webdriver.chrome.driver", "D:\\Workspaces\\chromedriver\\chromedriver.exe");
        } else {
            // 只考虑Linux环境,需要下载对应版本的驱动后放置在绝对路径/usr/bin目录下
            System.setProperty("webdriver.chrome.driver", "/usr/bin/chromedriver");
        }
        try {
            ChromeOptions options = new ChromeOptions();
            options.addArguments("--headless");
            options.addArguments("--disable-gpu");
            options.addArguments("--no-sandbox");
            options.addArguments("--remote-allow-origins=*");
            ChromeDriver driver = new ChromeDriver(options);
            driver.manage().window().maximize();
            driver.get(url);
            String jsHeight = "return document.body.clientHeight";
            long height = (long) driver.executeScript(jsHeight);
            int k = 1;
            int size = 500;
            while (k * size < height) {
                String jsMove = String.format("window.scrollTo(0,%s)", k * 500);
                driver.executeScript(jsMove);
                Thread.sleep(100);
                height = (long) driver.executeScript(jsHeight);
                k += 1;
            }

            // 通过执行脚本解决Selenium截图不全问题
            long maxWidth = (long) driver.executeScript(
                    "return Math.max(document.body.scrollWidth, document.body.offsetWidth, document.documentElement.clientWidth, document.documentElement.scrollWidth, document.documentElement.offsetWidth);");
            long maxHeight = (long) driver.executeScript(
                    "return Math.max(document.body.scrollHeight, document.body.offsetHeight, document.documentElement.clientHeight, document.documentElement.scrollHeight, document.documentElement.offsetHeight);");
            Dimension targetSize = new Dimension((int)maxWidth, (int)maxHeight);
            driver.manage().window().setSize(targetSize);

            Date date = new Date();
            SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd_HH-mm-ss");
            String strTime = sdf.format(date);

            File img = driver.getScreenshotAs(OutputType.FILE);
            FileUtils.copyFile(img, new File(strTime + ".png"));
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
