I need to access CSV-formatted data on a server, which requires a token for me to be granted access. My colleagues usually access this service with Python. However, as my code is all in MATLAB, I would prefer the data in MATLAB so that I can use my existing functions, which I have already verified.
In Python, we use the requests package as follows:
timeseries_url = 'https:// .... /csv'
payload = { 'variable': ['var1','var2'], 'platform_serial' : 'name_of_platform' , 'from' : 'start_time' , 'to' : 'end_time' }
header = {'Authorization': 'Bearer ' + 'authorisation_token'}
# Get the response:
response = requests.get(timeseries_url, headers=header, params=payload)
df = pandas.read_csv(io.StringIO(response.text))
I have been reading the MATLAB documentation for the HTTP interface. However, I have noticed there is no equivalent get command, but only the send.
I think the token should be entered in the matlab.net.http.HTTPOptions object as 'Credentials'. Similarly, the header could be the 'Header' matlab.net.http.RequestMessage. Besides, I think the payload could be obtained through 'getFields'. Are these assumptions correct?
How can I best achieve this task in MATLAB? Additionally, how can I change the data from CSV to matrices/cells for later use? I do not think using csvread or readmatrix here is appropriate.
My alternative is the MATLAB engine for Python, but I would prefer a neat, all-MATLAB solution.
Many thanks in advance for your help!
