推荐答案

如何在 Computed 中获取边框颜色或其他 css 值，您可以获得所有值:

How to get border color or other css values look in Computed there are all values that you can get:

getCssValue("border-bottom-color")

返回 rgba(209, 219, 223, 1) 并需要清除它(这适用于 rgba 和 rgb):

returns rgba(209, 219, 223, 1) and need to clear it (this will work for rgba and rgb):

String rgb[] = driver.findElement(By.name("login[email]")).getCssValue("border-bottom-color").replaceAll("(rgba)|(rgb)|(\()|(\s)|(\))","").split(",");

现在我们的 rgb 在数组中使用这个方法解析它

Now our rgb is in array using this method to parse it

String hex = String.format("#%s%s%s", toBrowserHexValue(Integer.parseInt(rgb[0])), toBrowserHexValue(Integer.parseInt(rgb[1])), toBrowserHexValue(Integer.parseInt(rgb[2])));

private static String toBrowserHexValue(int number) {
        StringBuilder builder = new StringBuilder(Integer.toHexString(number & 0xff));
        while (builder.length() < 2) {
            builder.append("0");
        }
        return builder.toString().toUpperCase();
    }

从这个 rgba(209, 219, 223, 1) 我们得到了这个 #D1DBDF

From this rgba(209, 219, 223, 1) we got this #D1DBDF

附言解析int rgb到hex的来源
