Hi Eveyone,
I have been trying to access the API data from MATLAB. However, I get en error of which screenshot is below. I am sure my credentials are correct.
Has anyone ever tried to pull the API data from MATLAB using RESTful request-response model?
Hi! Make sure that you write a JSON object, see the ‘Write JSON object’ section here: https://nl.mathworks.com/help/matlab/ref/webwrite.html
Hi Teun,
Thank you. It worked! I managed to receive the 'token' and 'idUser'.
However, this time, I have another issue regarding using the 'token' and 'idUser' information to pull the API data. Do you have any suggestion about how it can be done? Somehow, I should find a way to use the 'token' and 'idUser'.
Here are my code and error message:
url = 'https://vrmapi.victronenergy.com/v2/auth/login'
data = jsonencode(struct('username','***','password','***'))
response = webwrite(url,data)
headerFields = {'Authorization', ['Bearer ', response.token]};
options = weboptions('HeaderFields', headerFields, 'ContentType','json');
url2 = ('https://vrmapi.victronenergy.com/v2/users/'+ string(response.idUser) +'/installations')
resp2 = webwrite(url2,options);
It's been a while since I did a lot of matlab, but I think you should do it like this:
headerFields = {'Authorization', ['Bearer ' response.token]};
options = weboptions('HeaderFields', headerFields, 'ContentType','json');
url2 = ('https://vrmapi.victronenergy.com/v2/users/'+ string(response.idUser) +'/installations')
resp2 = webwrite(url2,[], options);
Note the subtle changes in the bearer array and the webwrite call arguments.
