Error using urlread to get results from queries

Hello,

I'm doing some Freebase query (for example : https://www.googleapis.com/freebase/v1/mqlread?query={"type":"/people/person","id":"/en/albert_ii_of_belgium","children":[]})

and I want to get the result in matlab.

So I did :

urlread(https://www.googleapis.com/freebase/v1/mqlread?query={"type":"/people/person","id":"/en/albert_ii_of_belgium","children":[]})

but I had the following error :

Error using urlread (line 111)
Error downloading URL. Your network connection may be down or your proxy settings improperly configured.

I haven't got any network problem.

However, I can't figure out how to solve this problem.

My matlab version is R2012b (32 bits).

Doc says:

    str = urlread(URL)

where URL is a Matlab string. You need to enclose the text by apostrophes to make it a Matlab string. This call (shortened to fit in one line) works here

    str = urlread( 'https://www.googleapis.com/..._belgium","children":[]}' )
    str =
    {
    "result": {
    "type": "/people/person", 
    "id": "/en/albert_ii_of_belgium", 
    "children": [
    "Philippe, Duke of Brabant", 
    "Prince Laurent of Belgium", 
    "Princess Astrid of Belgium, Archduchess of Austria-Este", 
    "Delphine Bo\u00ebl"
    ]
    }
    }
