带有“ span:contains('string')”的selenium.common.exceptions.InvalidSelectorException

带有“ span:contains('string')”的selenium.common.exceptions.InvalidSelectorException

我正在使用Firefox中的Selenium python。我正在尝试通过CSS选择器查找元素

element = "span:contains(''Control panel'')"my_driver.find_element_by_css_selector(element)

我低于错误

 raise exception_class(message, screen, stacktrace)selenium.common.exceptions.InvalidSelectorException: Message: Given css selector expression "span:contains(''Control panel'')" is invalid: InvalidSelectorError: ''span:contains(''Control panel'')'' is not a valid selector: "span:contains(''Control panel'')"

在Selenium IDE中,我可以通过此字段成功找到元素,但是在Python中,它不起作用

答案1

小编典典

css_selectorSelenium不支持使用按文本定位元素(尽管它可以在开发人员工具控制台中使用)。唯一的可能性是xpath

element = "//span[contains(text(), ''Control panel'')]"my_driver.find_element_by_xpath(element)

编辑:@FlorentB的评论:

css selector控制台也不支持A
,但是JQuery支持它。$(''...'')控制台中的from是该页面的缩写,document.querySelector通常会被JQuery覆盖。

Appium问题解决方案(4)- selenium.common.exceptions.InvalidSelectorException: Message: Locator Strategy 

Appium问题解决方案(4)- selenium.common.exceptions.InvalidSelectorException: Message: Locator Strategy 

背景

使用Appium Server 1.15.1版本

执行了以下脚本

test = driver.find_element_by_name("自动化测试")
print(test.text)

报了以下错误

 

 

圈重点

selenium.common.exceptions.InvalidSelectorException: Message: Locator Strategy 'name' is not supported for this session

简译:  by_name 这种定位元素方式已经不支持了

然后查了下资料,发现是在appium1.5之后, by_name 的这种定位方式已经彻底移除

 

解决方法一

最简单,不再用 by_name 定位方式了,改用id、class、xpath、accessibility id

 

解决方法二

看了网上的教程【driver.js】,最终发现也是没用的,这里就不展开了~还是换个定位方式叭!

2 解析

参考博客地址:https://blog.csdn.net/weixin_37577564/article/details/80329775

 

the server time zone value ''???ú±ê×??±??'' is unrecognized or represents more than one time zone.

出现这个的原因是因为 mysql 返回的时间总是有问题,比实际时间要早 8 小时。

jdbc 连接的 url 后面加上 serverTimezone=GMT 即可解决问题,如果需要使用 gmt+8 时区,需要写成 GMT%2B8

 

3 解决方法

注意:首先检查 mysql-connector-java-xxx.jar 的版本,若过低,升成 8.0.13

 

3.1 如果是在 Java 工具类里:

 

dataSource.setJdbcUrl("jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf8&serverTimezone=GMT%2B8&useSSL=false");

 

3.2 如果是在配置文件里:

<property name="jdbcUrl">jdbc:mysql://localhost:3306/test?useUnicode=true&amp;characterEncoding=utf8&amp;serverTimezone=GMT%2B8&amp;useSSL=false</property>

 

以上,吼吼
