Socvwid p7

[rleidner]

Current approach forces a new login in the VW Servers on each inquiry of the SOC.
This may cause a reaction on VW side in form of additional measures to make programmatic access from non-VW clients more difficult.
The unrequired login also costs about 50% of the total runtime.

Each login returns a new set of tokens.

The PR stores the tokens to a file in ramdisk (soc_vwid_tokensX (X=number of Ladepunkt).
On each query the tokens file is restored to the tokens in the vwid object and the tokens are reused until they become invalid.
If invalid the new tokens are stored in the file.

Tests done:

• Run without existing tokens file: works, SoC is returned, new file is created.
• Run with existing and valid tokens file: works, SoC is returned
• Run with existing but invalid tokens file: SoC is returned, new file is created.
• Run with tokens file owned by root: permission error is handled

Wenn Du gerade schon dran bist, kannst Du bitte alle fixen Verweise auf /var/www/html/openWB/... entfernen und das relativ lösen? Analog zu dem $OPENWBBASEDIR in der main.sh.

Hallo Lutz,
guter Hinweis :-)
Die Pfade sind jetzt relativ zu RAMDISKDIR.
