概述

WebDriver协议基于HTTP，使用JSON进行数据传输，定义了client与driver之间的通信标准。无论client的实现语言（如Java或C#），都能通过协议中的endpoints准确指示driver执行各种操作，覆盖了Selenium的所有功能。这些endpoints详细列出了所有可用的功能点。

目标

msedgedriver下载

启动

msedgedriver.exe --port=8080 --remote-allow-origins=* - --verbose -allow-insecure-localhost --allowed-origins=* --allowed-ips=["127.0.0.1"] --headless --disable-gpu

示例

#include "webdriver.h"int main() {WebDriver m_driver;m_driver.NavigateTo("https://www.hao123.com/");qDebug() << m_driver.getPageSource();
}
