java - 无法在 Java 中使用 phantomJS 处理警报

Question

我有一个如下的 Java 代码，当我运行 PhantomJs 时收到“不支持的命令异常”，但如果我运行 firefox 和 chrome，它工作正常:-

注意:使用 phantomJs，我们可以执行到下面代码中的第三步。我搜索了很多博客，但这些答案并没有解决我的问题。

1.      cvvField.sendKeys(cvcData);
2.      proceedToPayBtn.click();
3.      Reporter.log("Card details are submitted from payment UI page");
4.      Alert a1=driver.switchTo().alert();
5.      Reporter.log("Alert with text:"+a1.getText());
6.      a1.accept();   

此处 cvvField 和proceedToPayBtn 是WebElements，cvcData 的值为“111”。

错误日志:-

org.openqa.selenium.UnsupportedCommandException: Invalid Command Method - 

{"headers":{"Accept-Encoding":"gzip,deflate","Cache-Control":"no-cache","Connection":"Keep-Alive","Host":"localhost:30462","User-Agent":"Apache-HttpClient/4.5.1 (Java/1.8.0_101)"},"httpVersion":"1.1","method":"GET","url":"/alert_text","urlParsed":{"anchor":"","query":"","file":"alert_text","directory":"/","path":"/alert_text","relative":"

命令持续时间或超时:31 毫秒

I have edited above code as below but same error is coming.Please suggest

 if (driver instanceof PhantomJSDriver)
       {
         JavascriptExecutor je = (JavascriptExecutor) driver; 
         je.executeScript("window.alert = function(){};");
         je.executeScript("window.confirm = function(){return true;};");    
         System.out.println("Alert has been handled");
       } else {
             Alert a1 = driver.switchTo().alert();
             a1.accept();
       }                        

I am getting "Alert has been handled" in output console but alert is not handled.

由于等待时间而导致的某些问题可能是问题的根源 上面的代码可以帮助等待元素可见(因为 ngWebDriver 或 Selenium Webdriver 的等待与 PhantomJS 不兼容)

public static String waitJSResponse(PhantomJSDriver driver, String script) {
        String ReturnedValue = null;
        int sleeper = 10;
        Boolean flag = false;
        int timeOut = 30000;
        int i = 0;
        while ((!flag) & ((i*sleeper)<timeOut)) {
            try {
                Thread.sleep(sleeper);
                ReturnedValue = (String) driver.executeScript(script);

            } catch (Exception e) {
                flag = false;
                i++;
            }
            if (ReturnedValue != null) {
                flag = true;
                System.out.println("Overall wait time is : "+(i * sleeper)+" ms \n\r");
                break;
            }
        }
        return ReturnedValue;
    }

此代码将等待 10ms，然后验证元素是否可见，如果出现异常，则会再次循环。 返回值必须是文本、对象或任何不为空的内容。 script 值必须是您的 JS 脚本才能获取正确的元素。

希望它能成功。

我尝试了上面的代码:-

1.创建一个类“Test”并在其中编写上述方法。 2.通过创建一个对象(TestObject)来调用上述方法

TestObject.waitJSResponse((PhantomJSDriver) driver, "window.confirm = function(){return true;};");

但返回值在

尝试 {
Thread.sleep( sleep 者); ReturnedValue = (String) driver.executeScript(script); System.out.println(ReturnedValue);

}

返回 null。您能帮忙解决一下吗？
