download data from https

I would like to download data with webread from an https witha formed complex query (without using the basic query options in webread, websave as they would not work).

However I am getting a "Rorbidden" answer and error that does not explain much.

Any ideas?

Have you checked if the specific website allows non-human access?

Also, how do you expect us to give you a solution if you only tell us you're getting an 'access forbidden' error?

Hi,

As mentioned in the documentation. The Forbidden error is shown when Client does not have the correct credentials to make a request.

Hope this helps.

This error may also happen if non-human requests are blocked.

This is one of the websites I am trying to open.

https://patents.google.com/patent/US10000000B2/en?oq=us10000000

I can open it from my python script without credentials so I don't understand why it would not work in Matlab.

What exact code did you try?

>> mchp = webread("https://query1.finance.yahoo.com/v7/finance/download/MCHP?period=11624665600&period2=1624665600&interval=1d&events=history&includeAdjustedClose=true")

Error using matlab.internal.webservices.HTTPConnector/copyContentToByteArray (line 373)

The server returned the status 403 with message "Forbidden" in response to the request to URL

https://query1.finance.yahoo.com/v7/finance/download/MCHP?period1=1624665600&period2=1624665600&interval=1d&events=history&includeAdjustedClose=true.

Error in readContentFromWebService (line 46)

byteArray = copyContentToByteArray(connection);

Error in webread (line 125)

[varargout{1:nargout}] = readContentFromWebService(connection, options);

however I can use the following python code and it works:

response = ulib.request.urlopen("https://...")

data = response.read()

You can use Python from MATLAB - there is a webinar on that.
