C-код для клиента http-webdav с использованием CURLlibrary

Question

Я ищу код c для клиента http-webdav с использованием библиотеки CURL с включенной аутентификацией.

Я пробовал использовать некоторые примеры кодов, предоставляемых CURL, но, похоже, ничего не проходит методы аутентификациии работа.

Я включил дайджест-проверку подлинности с помощью пользователя и пароля.Запрос клиента отправляется правильно, но ответ сервера - 301. Я перехватил пакеты, используя wireshark.Есть что-то, чего не хватает?

Ниже приведен код, который я пробовал.

/* read callback function, fread() look alike */
static size_t read_callback(void *ptr, size_t size, size_t nmemb, void *stream)
{
  ssize_t retcode;
  curl_off_t nread;

  int *fdp = (int *)stream;
  int fd = *fdp;

  retcode = read(fd, ptr, size * nmemb);

  nread = (curl_off_t)retcode;

  fprintf(stderr, "*** We read %" CURL_FORMAT_CURL_OFF_T
          " bytes from file\n", nread);

  return retcode;
}


/*
 * This example shows a HTTP PUT operation. PUTs a file given as a command
 * line argument to the URL also given on the command line.
 *
 * This example also uses its own read callback.
