CEF 加载flash 插件

CEF可以通过命令行设置加载flash插件，有两种方式:

• 在程序启动时添加命令行参数

cef.exe --ppapi-flash-path=ppflash/18_0_0_209/pepflashplayer32_18_0_0_209.dll --ppapi-flash-version=18.0.0.209

• 重载OnBeforeCommandLineProcessing函数

class CCefClientApp : public CefApp,public CefBrowserProcessHandler
{
public:
    CCefClientApp();
    ~CCefClientApp();

    // CefApp methods:
    virtual CefRefPtr<CefBrowserProcessHandler> GetBrowserProcessHandler() override 
    {
        return this;
    }

    virtual void OnBeforeCommandLineProcessing(const CefString& process_type,CefRefPtr<CefCommandLine> command_line) override;

    // CefBrowserProcessHandler methods:
    virtual void OnContextInitialized() override;

private:
    // Include the default reference counting implementation.
    IMPLEMENT_REFCOUNTING(CCefClientApp);

private:

};

void CCefClientApp::OnBeforeCommandLineProcessing(const CefString & process_type,CefRefPtr<CefCommandLine> command_line)
{
    //加载flash插件
    command_line->AppendSwitchWithValue("--ppapi-flash-path","ppflash/18_0_0_209/pepflashplayer32_18_0_0_209.dll");
    //manifest.json中的version
    command_line->AppendSwitchWithValue("--ppapi-flash-version","18.0.0.209");


}
