截图代码报错
File screenshot = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE);
使用 Android 驱动程序截取屏幕截图时,代码都会出现报错:
java.lang.IllegalArgumentException: Illegal base64 character a

- 驱动程序尝试将 png 转换为 base64 时似乎失败了
环境细节:
版本
- npm 版本 : 8.11.0
- node 版本 : 16.16.0
- 运行 Appium 的操作系统:Mac 版本 13.0.1
- Android 手机版本 : 12.0.0
- appium server : 1.22.3
- [
jar包
] java-client : 8.2.0 - [
jar包
] selenium-java : 4.5.3
解决方案:
使用maven命令行mvn dependency:tree
查看对应项目的依赖树,对应Appium java 客户端下使用的selenium的依赖版本为4.5.3。
这是 Selenium 的问题,Appium java 客户端8.2.0版本应该引用selenium的依赖版本为4.5.0,修改pom文件中对应selenium
版本号即可解决。
如果还报错,则直接复制以下pom文件:
