Sweden: Raw Viva data

[HenrikBengtsson]

For example, for ViVa Station 45 (http://vivadisplay.sjofartsverket.se/#/station/45), I found via reverse engineering using Chrome Inspection that one can get the current live wind readings as:

$ curl 'https://services.viva.sjofartsverket.se:8080/output/vivaoutputservice.svc/vivastation/45?isMVY=false' -H 'User-Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:109.0) Gecko/20100101 Firefox/110.0' -H 'Accept: application/json, text/plain, */*' -H 'Accept-Language: en-US,en;q=0.5' -H 'Accept-Encoding: gzip, deflate, br' -H 'Origin: http://vivadisplay.sjofartsverket.se' -H 'Connection: keep-alive' -H 'Referer: http://vivadisplay.sjofartsverket.se/' -H 'Sec-Fetch-Dest: empty' -H 'Sec-Fetch-Mode: cors' -H 'Sec-Fetch-Site: cross-site' -H 'DNT: 1' -H 'Sec-GPC: 1' -H 'TE: trailers'

Same parsed via jq:

$ curl --silent 'https://services.viva.sjofartsverket.se:8080/output/vivaoutputservice.svc/vivastation/45?isMVY=false' -H 'User-Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:109.0) Gecko/20100101 Firefox/110.0' -H 'Accept: application/json, text/plain, */*' -H 'Accept-Language: en-US,en;q=0.5' -H 'Accept-Encoding: gzip, deflate, br' -H 'Origin: http://vivadisplay.sjofartsverket.se' -H 'Connection: keep-alive' -H 'Referer: http://vivadisplay.sjofartsverket.se/' -H 'Sec-Fetch-Dest: empty' -H 'Sec-Fetch-Mode: cors' -H 'Sec-Fetch-Site: cross-site' -H 'DNT: 1' -H 'Sec-GPC: 1' -H 'TE: trailers' | jq

Historical wind data (here Medelvind = average wind) for a specific ViVa station can be pulled using:

station_id=45
what="Medelvind"  ## (average wind) or "Byvind" (gust) or "Riktning" (direction)
url="https://services.viva.sjofartsverket.se:8080/output/vivaoutputservice.svc/vivastationhistory/${what}/${station_id}?isMVY=false"

curl --silent "${url}" -H 'User-Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:109.0) Gecko/20100101 Firefox/110.0' -H 'Accept: application/json, text/plain, */*' -H 'Accept-Language: en-US,en;q=0.5' -H 'Accept-Encoding: gzip, deflate, br' -H 'Origin: http://vivadisplay.sjofartsverket.se' -H 'Connection: keep-alive' -H 'Referer: http://vivadisplay.sjofartsverket.se/' -H 'Sec-Fetch-Dest: empty' -H 'Sec-Fetch-Mode: cors' -H 'Sec-Fetch-Site: cross-site' -H 'DNT: 1' -H 'Sec-GPC: 1' -H 'TE: trailers' | jq
