Data
As example we will store a temperature.
| Parameter | Value | since |
|---|---|---|
| API key | a10d3cca-370c-121e-b79c-2f0a58030a01 | r1 |
| Channel GUID | 87fd-cc15-cb33-71a8-6b78-3855-4c11-a79e | r1 |
| Temperature | 23.45 °C | r1 |
Insert data
To store data we send a PUT request from a console with Wikipedia:curl.
The API key must be send as a Header field named X-PVLng-key
Interesting is the HTTP code returned and the response body for error analysis in case of HTTP code is not 200 or 201.
$ set $(curl --request PUT \
–-write-out %{http_code} \
--output /tmp/pvlng.curl \
--header "X-PVLng-key: a10d3cca-370c-121e-b79c-2f0a58030a01" \
--data data=23.45 \
http://your.domain.here/api/r3/data/87fd-cc15-cb33-71a8-6b78-3855-4c11-a79e.txt)
To get readable error messages back, request content type text/plain (triggered by file extension .txt).
Simple check
$ test $1 -eq 200 -o $1 -eq 201 || echo "Error ($1): $(</tmp/pvlng.curl)" && exit 1
