How to resolve in matlab without using username and password. via access_token

[Manikanta Aditya]

Try this:

command = sprintf('command-line-tool --access-token %s', access_token);
[status, output] = system(command);

Here keep command-line-tool and access-token with your names. Also, please make sure your tool supports access token authentication and you’re using the correct option to provide the access token (in the example, it’s --access-token.)

i dont have clear idea about access token. where can i get it?

[Manikanta Aditya]

Application Access Control - MATLAB & Simulink (mathworks.com)

Check this documentation

is any matlab code or configuration available ?

[Manikanta Aditya]

Obtaining an access token typically involves making a request to the service’s authorization server with your client credentials (client ID and client secret). The specific details can vary depending on the service you’re using.

I can mention a very simple and basic example which can workout for you:

url = 'https://your-service.com/oauth/token';
options = weboptions('RequestMethod','post', 'MediaType','application/x-www-form-urlencoded');
data = ['grant_type=client_credentials&client_id=your-client-id&client_secret=your-client-secret'];
response = webread(url, data, options);
access_token = response.access_token;

thanks for the reply!!

here you mentioned ,

options = weboptions('RequestMethod','post', 'MediaType','application/x-www-form-urlencoded');

data = ['grant_type=client_credentials&client_id=your-client-id&client_secret=your-client-secret'];

inside ,

1. weboptions('RequestMethod','post', 'MediaType','application/x-www-form-urlencoded');

a. RequestMethod

b. post

c. MediaType

d. application/x-www-form-urlencoded

We need to mention?

2. data = ['grant_type=client_credentials&client_id=your-client-id&client_secret=your-client-secret'];

E.g, data = ['grant_type=client_credentials&client_id=748c1jk09-4090-09c79-kff40c-fcc9ee4f9863&client_secret=your-client-secret'];

what are the other things i want to mention? i have client id that one i mentioned above.

client secret where can i get?

Hello,

The first step is to obtain an access token from the service that you are using.

Then, you can include the access token in the "system" command to automate this process of logging in without providing a username and password.

Depending on the CLI application you are using, the command might be different.

The following is an example:

system('YourApplication.exe -s serverhostname:port --access-token YOUR_ACCESS_TOKEN');

@Dinesh thanks, the command which you given above thats fine.

how to obtain access token ? is any Matlab code available for this ?
