Question

我使用 Jacob Api在使用selenium自动化Web应用程序时上传文件，但它会产生UnsatisfiedLinkError。我是Jacob api的新文件上传所以请提前帮助和感谢。

示例脚本： -

public class FileUpload {
    public static void main(String a[]){
        WebDriver driver;
        try {
            System.setProperty("webdriver.chrome.driver", "/home/ionixx/workspace/IXAutomateNew1/chromedriver/chromedriver_linux");
            driver = new ChromeDriver();
            driver.manage().window().maximize();
            driver.navigate().to("http://test/admin/#/login");
            driver.findElement(By.id("email")).sendKeys("admin@test.com");
            driver.findElement(By.id("pass")).sendKeys("test");
            driver.findElement(By.className("adm-button-action")).click();
            Thread.sleep(5000);
            driver.findElement(By.xpath("html/body/div[1]/app-root/div/div[2]/div/app-project/div/div/div/div[1]/div/div[1]/h4/button")).click();
            driver.findElement(By.xpath("html/body/div[1]/app-root/div/div[2]/div/app-project/div/div/div/div[1]/div/div[2]/div[3]/div[5]/div/div[2]/label[1]")).click();
            String workingDir = System.getProperty("user.dir");
            final String jacobdllarch = System.getProperty("sun.arch.data.model")
                    .contains("32") ? "jacob-1.18-x86.dll" : "jacob-1.18-x64.dll";
            String jacobdllpath = workingDir + "/" + jacobdllarch;
            File filejacob = new File(jacobdllpath);
            System.setProperty(LibraryLoader.JACOB_DLL_PATH,
                    filejacob.getAbsolutePath());
            AutoItX uploadWindow = new AutoItX();

            String filepath = workingDir + "/home/ionixx/Downloads/123.pdf";
            driver.get(filepath);
            if (uploadWindow.winWaitActive("File Upload", "", 5)) {
                if (uploadWindow.winExists("File Upload")) {
                    uploadWindow.sleep(100);
                    uploadWindow.send(filepath);
                    uploadWindow.controlClick("File Upload", "", "&Open");
                }
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

输出： -

在我弄清楚这一点之前，我度过了一段非常艰难的时期。祝你好运！

您需要将Jacob dll文件复制到System32文件夹（或SysWOW64文件夹 - 取决于您使用x86与x64的JRE / JDK类型）。

Copy these dll files:
jacob-1.18-x86.dll
jacob-1.18-x64.dll

然后，

paste them in System32 folder:
    C:\Windows\System32

If it still doesn't work copy the dll files to: 
    C:\Windows\SysWOW64

使用Jacob api和selenium自动化Web应用程序会产生UnsatisfiedLinkError
