Selenium浏览器自动化

浏览器自动化允许您在Multilogin的浏览器配置文件中自动执行任务。从创建简单的自动化脚本到复杂的Web爬虫，可以搜索、收集Web数据并与之交互。
Multilogin浏览器自动化基于Selenium WebDriver。
通常情况下，如果您运行Selenium代码，首先将连接到Firefox（Gecko）或Chrome驱动，然后设置您所需要的功能。而将Multilogin与Selenium代码结合使用时，您无需这样操作。
您将使用Remote Web Driver程序，通过本地端口连接到Multilogin应用或某浏览器配置文件，设置所需功能，在预定义的浏览器配置文件中执行Selenium命令。
支持的语言
Selenium框架提供了多种可搭配使用的语言，因此Multilogin自动化也可以在多种编码语言上运行。但是目前，我们仅为Java和Python供技术支持。
在 Multilogin 中使用Selenium
定义Multilogin端口:
您需要提前定义软件端口以使用Selenium自动化。以下是定义端口的方法：
- 前往C:\Users\%username%\.multiloginapp.com路径并打开app.properties文件
- 添加此语句:
multiloginapp.port=[PORT_NUMBER]
端口号的范围为10000 ~ 49151
- 保存 app.properties 文件
随后，您就可以通过定义的端口连接到Multiogin了。
