通过使用 TChromium.OnLoadError 并调用 TChromium.LoadString 来显示我自己的错误页面来解决此问题
回调的参数 errorCode 有以下值：
| const | |
| // Error list defined in /include/internal/cef_types.h (cef_errorcode_t) | |
| // which includes this file /include/base/internal/cef_net_error_list.h | |
| // which includes this Chromium source file /net/base/net_error_list.h | |
| // available here in the master branch -> https://chromium.googlesource.com/chromium/src/+/master/net/base/net_error_list.h | |
| // compare the values in the right Chromium branch. | |
