C++ 使用libcurl创建新目录

我一直在修补libcurl，到目前为止它还不错。我有几件事让我很困惑。我需要为远程服务器创建一个目录，这里有一些问题

我在URL中传递什么？它是根URL还是完整目录

我希望在创建目录时产生连锁反应，也就是说，如果我有diectory/abc/def/ghi，那么如果它们不存在，就应该创建它们。我已经尝试了CURLOPT_FTP_CREATE_MISSING_Dir，但不起作用

它失败了，我不能确定原因。下面是应用程序的相关代码和日志

确保路径的格式为/public\u html/somedir，而不是

这就是我的代码出错的原因。所以我通过删除URL解决了这个问题。我认为应该有一个关于libcurl的部分来解释预期的URL格式。一旦我完全掌握了它，我将为此做出贡献

CURL* handle = curl_easy_init();

SetHandleOptions(handle); //set options

CURLcode res;
wxString uploadUrl =....;//full URL with path like ftp.xyz.com/public_html/dir1/
wxString command1 = "MKD "+uploadUrl;
wxString command2 = "CWD "+uploadUrl;
struct curl_slist *headers = NULL;
headers = curl_slist_append(headers, command1.c_str());
headers = curl_slist_append(headers, command2.c_str());
curl_easy_setopt(handle, CURLOPT_QUOTE, headers);
const char* uploadUrlStr = uploadUrl.c_str();

if(handle)
{
    //do file upload here
    /* upload to this place */
    curl_easy_setopt(handle, CURLOPT_URL, uploadUrlStr);
    /* enable verbose for easier tracing */
    curl_easy_setopt(handle, CURLOPT_VERBOSE, 1L);
    curl_easy_setopt(handle, CURLOPT_FTP_CREATE_MISSING_DIRS, 1L);
    curl_easy_setopt(handle, CURLOPT_QUOTE, headers);

    res = curl_easy_perform(handle);

    if(res==CURLE_OK)
    {
        SendMessage(_("Successfully Created Directory: ")+uploadUrl, HERROR_TYPE_WARNING);
    }
    else
    {
        //send error message
        wxString str(curl_easy_strerror(res));
        SendMessage(str);
    }
    /* always cleanup */
    curl_easy_cleanup(handle);

}
else
{
    SendMessage(_("Could Not Connect to Server: Invalid Handle"), HERROR_TYPE_CRITICAL);
}

curl_slist_free_all(headers);
