因?yàn)轫?xiàng)目需要，需要將游戲手機(jī)助手中的朋友圈給移植到PC游戲中，而以前游戲中的內(nèi)嵌瀏覽器采用的是IE6內(nèi)核，滿足不了我們的需求，于是決定把Cef3內(nèi)嵌到游戲中，在完成正常工作之余，利用閑散時(shí)間不斷地查找各種資料，初步完成了項(xiàng)目需求，決定寫(xiě)一篇文章來(lái)記錄我碰到的各種坑。 一開(kāi)始我只是在網(wǎng)上找了一個(gè)最后支持XP系統(tǒng)的版本–2623版本，利用這個(gè)版本進(jìn)行開(kāi)發(fā)，后來(lái)發(fā)現(xiàn)不支持MP3、MP4，是需要重新編譯一個(gè)支持MP3、MP4的版本的，在網(wǎng)上找一個(gè)已編譯好了的版本（在Windows下編譯Cef3.2623并加入mp3、mp4支持（附帶源碼包和最終DLL）），最后把一些dll、資源等替換下就行，并不需要更改工程代碼，非常感謝Redrain！附上鏈接：http://blog.csdn.net/zhuhongshu/article/details/54193842 一、首先來(lái)了解下Cef3CEF全稱Chromium Embedded Framework，是一個(gè)基于Google Chromium 的開(kāi)源項(xiàng)目。CEF的典型應(yīng)用場(chǎng)景包括： 嵌入一個(gè)兼容HTML5的瀏覽器控件到一個(gè)已經(jīng)存在的本地應(yīng)用。 · 創(chuàng)建一個(gè)輕量化的殼瀏覽器，用以托管主要用Web技術(shù)開(kāi)發(fā)的應(yīng)用。 · 有些應(yīng)用有獨(dú)立的繪制框架，使用CEF對(duì)Web內(nèi)容做離線渲染。 · 使用CEF做自動(dòng)化Web測(cè)試。 CEF3是基于Chomuim Content API多進(jìn)程構(gòu)架的下一代CEF，擁有下列優(yōu)勢(shì)： · 改進(jìn)的性能和穩(wěn)定性（JavaScript和插件在一個(gè)獨(dú)立的進(jìn)程內(nèi)執(zhí)行）。 · 支持Retina顯示器。 · 支持WebGL和3D CSS的GPU加速。 · 類似WebRTC和語(yǔ)音輸入這樣的前衛(wèi)特性。 · 通過(guò)DevTools遠(yuǎn)程調(diào)試協(xié)議以及ChromeDriver2提供更好的自動(dòng)化UI測(cè)試。 · 更快獲得當(dāng)前以及未來(lái)的Web特性和標(biāo)準(zhǔn)的能力。 翻譯自https:///chromiumembedded/cef/wiki/GeneralUsage.md 看不懂英文的可以看這篇GeneralUsage翻譯文：https://github.com/fanfeilong/cefutil/blob/master/doc/CEF General Usage-zh-cn.md#important-concepts 二、二進(jìn)制文件及資源文件說(shuō)明
有些是根據(jù)情況可刪減的，cef可以繼續(xù)運(yùn)行，或缺失部分功能：
三、引入到工程中因?yàn)槭莾?nèi)嵌在我們自己的項(xiàng)目中，所以只需要給工程中引入cef3，將一些dll等資源文件加入到工程exe所在目錄下，在我們自己的第三方庫(kù)文件夾中加入了cef3文件夾，里面加入cef的include文件夾，和lib文件夾，lib文件夾里分別放入的是debug版本和release版本的libcef.lib文件和libcef_dll_wrapper.lib文件。
四、Cef基礎(chǔ)概念1、多進(jìn)程架構(gòu) #define REQUIRE_UI_THREAD() ASSERT(CefCurrentlyOn(TID_UI)); #define REQUIRE_IO_THREAD() ASSERT(CefCurrentlyOn(TID_IO)); #define REQUIRE_FILE_THREAD() ASSERT(CefCurrentlyOn(TID_FILE)); 3、字符串 std::string str = “Some UTF8 string”; // Equivalent ways of assigning |str| to |cef_str|. Conversion from UTF8 will occur if necessary. CefString cef_str(str); cef_str = str; cef_str.FromString(str); // Equivalent ways of assigning |cef_str| to |str|. Conversion to UTF8 will occur if necessary. str = cef_str; str = cef_str.ToString(); 和std::wstring的相互轉(zhuǎn)換： // Equivalent ways of assigning |str| to |cef_str|. Conversion from wide will occur if necessary. CefString cef_str(str); cef_str = str; cef_str.FromWString(str); // Equivalent ways of assigning |cef_str| to |str|. Conversion to wide will occur if necessary. str = cef_str; str = cef_str.ToWString(); 4、入口函數(shù) CefMainArgs main_args(hInstance); 5、單一執(zhí)行體 int main(int argc, char* argv[]) {
// Structure for passing command-line arguments.
// The definition of this structure is platform-specific.
CefMainArgs main_args(argc, argv);
// Optional implementation of the CefApp interface.
CefRefPtr<SimpleApp> app(new SimpleApp);
// Execute the sub-process logic, if any. This will either return immediately for the browser
// process or block until the sub-process should exit.
int exit_code = CefExecuteProcess(main_args, app.get());
if (exit_code >= 0) {
// The sub-process terminated, exit now.
return exit_code;
}
// Populate this structure to customize CEF behavior.
CefSettings settings;
// Initialize CEF in the main process.
CefInitialize(main_args, settings, app.get());
// Run the CEF message loop. This will block until CefQuitMessageLoop() is called.
CefRunMessageLoop();
// Shut down CEF.
CefShutdown();
return 0;
}6、分離子進(jìn)程執(zhí)行體 主程序的入口函數(shù)： // Program entry-point function.
// 程序入口函數(shù)
int main(int argc, char* argv[]) {
// Structure for passing command-line arguments.
// The definition of this structure is platform-specific.
// 傳遞命令行參數(shù)的結(jié)構(gòu)體。
// 這個(gè)結(jié)構(gòu)體的定義與平臺(tái)相關(guān)。
CefMainArgs main_args(argc, argv);
// Optional implementation of the CefApp interface.
// 可選擇性地實(shí)現(xiàn)CefApp接口
CefRefPtr<SimpleApp> app(new SimpleApp);
// Populate this structure to customize CEF behavior.
// 填充這個(gè)結(jié)構(gòu)體，用于定制CEF的行為。
CefSettings settings;
// Specify the path for the sub-process executable.
// 指定子進(jìn)程的執(zhí)行路徑
CefString(&settings.browser_subprocess_path).FromASCII(“/path/to/subprocess”);
// Initialize CEF in the main process.
// 在主進(jìn)程中初始化CEF
CefInitialize(main_args, settings, app.get());
// Run the CEF message loop. This will block until CefQuitMessageLoop() is called.
// 執(zhí)行消息循環(huán)，此時(shí)會(huì)堵塞，直到CefQuitMessageLoop()函數(shù)被調(diào)用。
CefRunMessageLoop();
// Shut down CEF.
// 關(guān)閉CEF
CefShutdown();
return 0;
}子進(jìn)程程序的入口函數(shù)： // Program entry-point function.
// 程序入口函數(shù)
int main(int argc, char* argv[]) {
// Structure for passing command-line arguments.
// The definition of this structure is platform-specific.
// 傳遞命令行參數(shù)的結(jié)構(gòu)體。
// 這個(gè)結(jié)構(gòu)體的定義與平臺(tái)相關(guān)。
CefMainArgs main_args(argc, argv);
// Optional implementation of the CefApp interface.
// 可選擇性地實(shí)現(xiàn)CefApp接口
CefRefPtr<SimpleApp> app(new SimpleApp);
// Execute the sub-process logic. This will block until the sub-process should exit.
// 執(zhí)行子進(jìn)程邏輯，此時(shí)會(huì)堵塞直到子進(jìn)程退出。
return CefExecuteProcess(main_args, app.get());
}7、CefSettings 8、CefApp 9、CefClient 到這你差不多就知道cef3是怎么一回事了。我們可以上代碼了 五、上代碼先說(shuō)兩點(diǎn)： // 初始化函數(shù)：

CefEnableHighDPISupport();

#if defined(CEF_USE_SANDBOX)

CefScopedSandboxInfo scoped_sandbox;
sandbox_info = scoped_sandbox.sandbox_info();
#endif
// Provide CEF with command-line arguments.
CefMainArgs main_args(hInstance); // hInstance是游戲窗口的實(shí)例句柄（HINSTANCE）
// Parse command-line arguments.
CefRefPtr<CefCommandLine> command_line = CefCommandLine::CreateCommandLine();
command_line->InitFromString(::GetCommandLineW());
// Create a ClientApp of the correct type.
CefRefPtr<CefApp> app;
// The command-line flag won't be specified for the browser process.
if (!command_line->HasSwitch("type"))
{
app = new SimpleApp();
}

{
const std::string& processType = command_line->GetSwitchValue("type");
if (processType == "renderer")
{
app = new SimpleApp();
}
else
{
// app = new SimpleOtherApp();
}
}
// CEF applications have multiple sub-processes (render, plugin, GPU, etc)
// that share the same executable. This function checks the command-line and,
// if this is a sub-process, executes the appropriate logic.
int exit_code = CefExecuteProcess(main_args, NULL, sandbox_info);
if (exit_code >= 0) {
// The sub-process has completed so return here.
return exit_code;
}
// Specify CEF global settings here.
CefSettings settings;
#if !defined(CEF_USE_SANDBOX)
settings.no_sandbox = true;
#endif
// 在這設(shè)置用于啟動(dòng)子進(jìn)程單獨(dú)執(zhí)行器的路徑
WCHAR subProcessPath[260] = { 0 };
GetModuleFileNameW(hInstance, subProcessPath, 260);

LPCWSTR SUB_PROCESS_NAME = L"zt2asHelp.exe";

}至此，幾乎所有的核心代碼都準(zhǔn)備好了，除了在游戲里創(chuàng)建我們的瀏覽器。 六、坑因?yàn)槲覀働C游戲只創(chuàng)建一個(gè)windows窗口，游戲里面的dialog都是模擬出來(lái)的，并非windows窗口。要把cef直接顯示游戲里，并且是可以拖動(dòng)位置，我的做法是在游戲里面創(chuàng)建一個(gè)新的windows子窗口，同時(shí)在游戲里創(chuàng)建一個(gè)游戲窗口，把windows子窗口的位置綁定到新建的游戲窗口上，當(dāng)拖動(dòng)游戲窗口時(shí)，同時(shí)也移動(dòng)windows子窗口，然后再把cef的瀏覽器內(nèi)容顯示在windows子窗口上。 七、還有很多坑像游戲里的焦點(diǎn)問(wèn)題，鍵盤(pán)事件問(wèn)題等等。 <!DOCTYPE HTML>
