我在用java+selenium+chromewebdriver爬数据的时候，
这个网站frame内的table表格内又嵌套了iframe，我不知道为什么我无法通过
switchto().frame(id)获取其他方法定位到此iframe。求大佬解惑
WebDriver webDriver = getWebDriver("dataUrls");
try {
TimeUnit.SECONDS.sleep(2);
WebDriver driver = webDriver.switchTo().frame("SI2_mem_index");
driver.findElement(By.id("username")).sendKeys("jv39737");
driver.findElement(By.id("passwords")).sendKeys("aaa222");
driver.findElement(By.xpath("//div[@class=\"za_button\"]")).click();
TimeUnit.SECONDS.sleep(3);
WebDriver index = driver.switchTo().frame("SI2_mem_index");
//第一种方式
WebDriver body = index.switchTo().frame("body");
//第二种方式
WebDriver frame = index.switchTo().frame(0);
//第三种方式
WebElement iframe = index.findElement(By.tagName("iframe"));
index.switchTo().frame(iframe);
} catch (Exception e) {
webDriver.quit();
e.printStackTrace();
}
