A diretiva é Environment
, não EnvironmentVariable
.
Environment=
Sets environment variables for executed processes. Takes a space-separated list of variable assignments. This option may be specified more than once, in which case all listed variables will be set. If the same variable is set twice, the later setting will override the earlier setting.
Environment=PARAM1=123
Environment=PARAM2=444
OR
Environment=PARAM1=123 PARAM2=444
Não tenho certeza, mas talvez seja necessário usá-los entre chaves {}
:
--post-data=key1=${PARAM1}&key2=${PARAM2}
