<p>This server also supports experimental data ingest. If the server
configuration at HAPI_HOME/keys/ contains a key for a data product,
then this allows post requests to insert data into the server.
For example, the scientist if digitizing data and this allows the data
to be stored in a common location.
</p>
<p>A multipart upload is needed to push data. This should contain the
firstly "key" which secures the server. This is a unique string
known to the server implementation and to the client using it.
(Presently this is an 8-digit number.) Second, the post contains
the csv-formatted data in "data".</p>
<p>This Python code shows how to push data. Suppose you have a chicken
coop with a Raspberry PI and a temperature sensor. We wish to
regularly store the temperature of the chicken coop by pushing data
into a HAPI server. Here is the Python code (after 'pip install requests'):
<code><pre>
import requests
data = {'key':'12345678',
'data':'2021-01-01T00:00Z,-4.4\n2021-01-01T01:00Z,-4.6\n'}
r = requests.post(url = 'http://localhost:8084/HapiServerDemo/hapi/data?id=chickens', data = data)
</pre></code>
Note the server is able to get the key from the post part of the request.
<p>wget can be used to insert a record as well:
<code><pre>
wget --post-data='data=2002-02-02T00:00Z,4.56' 'http://localhost:8084/HapiServerDemo/hapi/data?id=chickens&key=12345678'
</pre></code>
or to avoid having the key appear in server logs:
<code><pre>
wget --post-data='key=12345678&data=2002-02-02T00:00Z,4.56' 'http://localhost:8084/HapiServerDemo/hapi/data?id=chickens'
</pre></code>
