SeleniumLibrary对话框异常：用户输入对话框点击确定后无法关闭

我编写了一个Robot Framework脚本，用于获取用户名、密码和路由器序列号，导航至指定网站完成登录及路由器序列号查询操作。脚本可正常弹出三个输入对话框，但输入序列号并点击确定按钮后，该对话框始终无法关闭。尽管后续脚本仍能正常执行并填充相关信息，但这个弹窗问题一直存在。我是Python新手，恳请提供解决方案。

方法1：替换GUI弹窗为控制台输入 #

Dialogs库的GUI弹窗可能和Selenium启动的Chrome浏览器存在焦点冲突，导致第三个弹窗无法正常关闭。改用OperatingSystem库的Get Input From Console在控制台输入信息，可避免该问题：

修改测试用例部分代码：

*** Test Cases ***
Get Credentials
    ${ECO_username}=   Get Input From Console    Enter ECO user name [默认值: admin]
    Log To Console  \n${ECO_username}
    ${ECO_password}=   Get Input From Console    Enter ECO password
    Log To Console  \n${ECO_password}
    ${ECO_serial}=   Get Input From Console    Enter router serial [默认值: serial]
    Log To Console  \n${ECO_serial}

    [Tags]             smoke test
    Open Browser  ${url}  chrome

注：控制台输入无法隐藏密码，若需隐藏密码，可结合Python的getpass库自定义关键字，或改用命令行参数方式。

方法2：调整执行顺序 #

若必须使用Dialogs库，可尝试先启动浏览器，等待加载完成后再弹出输入对话框，减少焦点冲突概率：

*** Test Cases ***
Get Credentials
    [Tags]             smoke test
    Open Browser  ${url}  chrome
    Maximize Browser Window
    Sleep  2s  # 等待浏览器完全加载

    ${ECO_username}=   Get Value From User   Enter ECO user name  admin
    Log To Console  \n${ECO_username}
    ${ECO_password}=   Get Value From User   Enter ECO password  hidden=yes
    Log To Console  \n${ECO_password}
    ${ECO_serial}=   Get Value From User   Enter router serial  serial
    Log To Console  \n${ECO_serial}

方法3：使用命令行参数传递（推荐自动化场景） #

自动化脚本更适合通过命令行参数传递敏感信息和配置值，避免手动输入交互：

*** Test Cases ***
Get Credentials
    # 执行脚本时通过命令行传递参数：robot --variable ECO_USER:admin --variable ECO_PASS:P@ssword1 --variable ECO_SERIAL:MQ25761000110 your_script.robot
    ${ECO_username}=    Get Variable Value    ${ECO_USER}    default=admin
    ${ECO_password}=    Get Variable Value    ${ECO_PASS}    default=P@ssword1
    ${ECO_serial}=      Get Variable Value    ${ECO_SERIAL}    default=serial

    Log To Console  \nECO用户名: ${ECO_username}
    Log To Console  \n路由器序列号: ${ECO_serial}
