Question

是否可以过滤调试数据功能文本？我希望一次显示命令而另一次显示完整输出（我想要例如过滤掉Adding handle: send: 0）。我一直收到很多消息。我想要像Filezilla Short消息一样好的东西。

这是我的调试功能代码，下面是一条消息。我已启用详细信息

int Uploader::DebugDataCallBack(CURL* handle, curl_infotype infotype, char* msg, size_t size, void* f)
{
    int level= 1; //debug info 0-None, 1-necessary 2 - All TODO: Should come from config
    switch(level) //error level
    {
        case 0:
        {
            break; //do nothing
        }
        case 1:
        {
            //only necessary, skip headers
            if(infotype==CURLINFO_TEXT)
            {
                static_cast<Uploader*>(f)->SendMessage(wxString(msg));
            }
        }
        default:
        {
            //full debug messages
            static_cast<Uploader*>(f)->SendMessage(wxString(msg));
        }
    }

    return 0;//must return 0
}

首先通过在curl_easy_setopt中将详细信息设置为CURLOPT_VERBOSE的1L来启用curl。它设置了调试功能，即CURLOPT_DEBUGFUNCTION来接收调试消息。然后使用代码信息类型来过滤掉你想要的东西。如果你想获得命令/响应，就像我想要从Header输入/输出消息。这是一段代码，只是为了展示它！

switch(infotype)
{
    case CURLINFO_HEADER_OUT:
    {
        wxString message = _("COMMAND: ")+wxString(msg);
        SendMessage(message);
        break; 
    }
    case CURLINFO_HEADER_IN:
    {
        wxString message = _("RESPONSE: ")+wxString(msg);
        SendMessage(message);
        break;
    }

}
