Access data from ZVV using their HAFAS endpoint

[Feuermurmel]

It seems that the data returned for the ZVV services does not contain any prognoses when the pre-configured endpoint from the SBB is used. Has anyone already tried to access the HAFAS endpoint from the ZVV?

I looked at the data transferred when making requests from the ZVV app for iPhone but they don't look like anything I recognize. The HTTP requests say that they're using a content type application/x-www-form-urlencoded, but the body contains binary data. The responses use a content type of application/x-bxml.

Searching for that string lead me to the specification for Binary XML, but it doesn't look like the data is in that format, or was encoded further because the header does not match the description in the specification for that format.

Hello,

I think ZVV endpoint does not support "extxml.exe" interface as SBB. What I ended up is implementing a connector to "stboard.exe" and "query.exe" endpoint. You can see how it works in my fork of the repo (https://github.com/dragoon/Transport/blob/master/lib/Transport/Providers/ZVV.php).

That sounds like it's gzipped. Tools like mitmproxy (or Wireshark) will automatically display plain text if it is gzipped. Maybe it is also Binary XML, gzipped.

Look for the Content-Encoding HTTP header.

Is there a /bin/mgate.exe route available for ZVV? This is what the apps for Berlin (VBB, BVG) and Deutsche Bahn talk to. See vbb-hafas for an almost feature-complete client.

FYI there is Java code querying query.exe from ZVV.
