MATLAB: Is a url valid

Question

Hello,

I'd like to know if a url is valid or not.

For example :

    - http://www.fkhzfziufhzoij.com      is not valid
    - http://www.mathworks.fr            is valid

Do you think it's possible ? thank you

Answer 1

The documentation for urlread indicates that you could use the status output variable to indicate if the operation is successful or not.

For your two examples,

 [str,status] = urlread('http://www.fkhzfziufhzoij.com');

returns an empty str and status==0.

Whereas,

 [str,status] = urlread('http://www.mathworks.fr');

returns the HTML for the page in str and status==1.
