1、忽略證書錯誤提示，cef默認為false，但是并沒有彈窗提示要去選擇操作，所以會導致某一些需要驗證證書的界面打不開。
解決：

settings.ignore_certificate_errors = true;

2、本地化問題
解決：

  const char* loc = "zh-CN";
  CefString(&settings.locale).FromASCII(loc);
  CefString(&settings.accept_language_list).FromASCII(loc);
  cef_string_from_ascii(loc, strlen(loc), &settings.locale);

3、cef70中flash無法自動打開問題

void QCefRenderApp::OnBeforeCommandLineProcessing(const CefString &process_type, CefRefPtr<CefCommandLine> command_line)
{
    //flash
    command_line->AppendSwitchWithValue("enable-system-flash", "1");        //這一句就夠了
//    command_line->AppendSwitchWithValue("ppapi-flash-version", "99.0.0.999");
//    command_line->AppendSwitchWithValue("ppapi-flash-path", "plugins\\pepflashplayer64_32_0_0_344.dll");
}

4、編譯cef出錯

錯誤  1   error MSB3073: 命令“setlocal
mt.exe -nologo -manifest "E:/CEF_Source/cef81/tests/cefclient/resources/win/cefclient.exe.manifest" "E:/CEF_Source/cef81/tests/cefclient/resources/win/compatibility.manifest" -outputresource:"E:/CEF_Source/cef81/out/tests/cefclient/Debug/cefclient.exe";#1
