C++ WebDriver扩展

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 --port8080 --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(); }效果webdriver.h#ifndef WEBDRIVER_H #define WEBDRIVER_H #include QNetworkAccessManager #include QNetworkReply class WebDriver : public QObject { Q_OBJECT public: WebDriver(); ~WebDriver(); void getStatus(); void getTimeout(); void setTimeOut(int implicit, long long pageLoad, long long script); void NavigateTo(const QString url); QString getCurrentUrl(); void historyBack(); void historyForward(); void refresh(); QString getTitle(); QString showWindow(); void closeWindow(); void getWindowHandles(); void createWindow(); QString getPageSource(); signals: void response(const QByteArray bytes); private: void connectToServer(const QUrl url); private: void post(const QByteArray bytes); void get(); void deleteRes(); private: void waitFinish(); private: QString m_host; QNetworkAccessManager m_networkManger; QNetworkRequest m_client; std::string m_sessionID; std::string m_elementID; QByteArray m_responseCache; }; #endif // WEBDRIVER_Hwebdriver.cpp#include webdriver.h #include QElapsedTimer #include QApplication #include QJsonDocument #include QJsonObject #include webDriverResponseJson.h #include webDriverRequestJson.h WebDriver::WebDriver() : m_host(http://127.0.0.1:8080){ connectToServer(QUrl(m_host /session)); } WebDriver::~WebDriver() { if (m_sessionID.empty()) return; m_client.setUrl(QUrl(m_host QString(/session/) QString::fromStdString(m_sessionID))); deleteRes(); waitFinish(); } void WebDriver::connectToServer(const QUrl url) { m_client.setUrl(url); m_client.setHeader(QNetworkRequest::ContentTypeHeader, application/json; charsetutf-8); m_client.setHeader(QNetworkRequest::UserAgentHeader, Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/128.0.0.0 Safari/537.36 Edg/128.0.0.0); m_client.setRawHeader(Cache-Control, no-cache); REQ::Options options; options.capabilities.browserName edge; std::string json JS::serializeStruct(options, JS::SerializerOptions(JS::SerializerOptions::Compact)); post(QString::fromStdString(json).toLocal8Bit()); waitFinish(); // 反序列 RES::MSEdgeRoot response; JS::ParseContext parseContext(m_responseCache.data()); auto error parseContext.parseTo(response); if (JS::Error::NoError ! error) { std::string errorStr parseContext.makeErrorString(); fprintf(stderr, Error parsing struct %s\n, errorStr.c_str()); } m_sessionID response.value.sessionId; } void WebDriver::NavigateTo(const QString url) { m_client.setUrl(QUrl(m_host QString(/session/) QString::fromStdString(m_sessionID) /url)); REQ::NavigateTo nav; nav.url url.toStdString(); std::string json JS::serializeStruct(nav, JS::SerializerOptions(JS::SerializerOptions::Compact)); post(QString::fromStdString(json).toLocal8Bit()); waitFinish(); QJsonParseError jsonError; QJsonDocument doucment QJsonDocument::fromJson(m_responseCache, jsonError); // 转化为 JSON 文档 if (!doucment.isNull() (jsonError.error QJsonParseError::NoError)) { // 解析未发生错误 if (doucment.isObject()) { // JSON 文档为对象 QJsonObject object doucment.object(); // 转化为对象 if (object.contains(value)) { // 包含指定的 key QJsonValue value object.value(value); // 获取指定 key 对应的 value qDebug() NavigateTo (value.isNull() ?
