ошибка скручивания 52 при доступе к https при работе wget

0 голосов
/ 13 ноября 2018

Я пытаюсь получить доступ к веб-интерфейсу телефона Snom D315 через curl (7.62.0 в macOS), но постоянно получаю сообщение об ошибке 52 (CURLE_GOT_NOTHING): 

$ curl --insecure --user admin:password https://172.16.99.61/settings.xml
curl: (52) Empty reply from server

Интересные факты:

  • доступ по HTTP работает, как и ожидалось
  • страница (HTTPS) просто прекрасно открывается в браузере или через wget (1.19.5)
  • это также работает на старых Snom D300 устройствах (с другой прошивкой, конечно)

Любая помощь приветствуется!

PS: Я имеюпрочитайте ответы на этот вопрос , но безрезультатно.Я также подтвердил это с другим D315 и curl 7.52.1 в Debian и обновил прошивку телефона до последней версии.

Вот вывод curl --trace-ascii --trace-time --insecure --user admin:password https://172.16.99.61/settings.xml:

Теперь это интересно: добавление заголовка Connection: keep-alive вручную заставляет все работать: 

$ curl -sSL -D - -o /dev/null --insecure -H 'Connection: keep-alive' --user admin:xxxxx https://172.16.99.61/settings.xml
Wed Nov 14 11:18:13 CET 2018
HTTP/1.1 200 Ok
Server: snom embedded
Cache-Control: no-cache
Cache-Control: no-store
Content-Type: text/xml
Content-Length: 110192

В то время как без него это не: 

$ curl -sSL -D - -o /dev/null --insecure --user admin:xxxxx https://172.16.99.61/settings.xml
Wed Nov 14 11:19:53 CET 2018
