Question

I am using this code to download file from server and parse data from JSON notation:

        WebClient wcl = new WebClient();
        Uri url = new Uri(tickurl);
        string srlz = wcl.DownloadString(url);
        var dict = (new JavaScriptSerializer()).Deserialize<Dictionary<string, dynamic>>(srlz);

When I use it with http://deepbit.net/api/ + my token (URI returns JSON data) it works well.

But with https://mtgox.com/code/data/ticker.php it stucks on 3rd line of the function(data downloading).

What am i doing wrong? Both URLs return same JSON formatted data.

[add] it’s not issue with https, this code works well enough with other https services. i am wondering if this could be a problem with SSL cert.

SOLVED: turned off SSL certificate validation. thanks

Answer 1

I suspect it’s failing due to a security problem. When I fetch with wget, I get:

ERROR: certificate common name www.mtgox.com' doesn't match requested host namemtgox.com’

It’s fine when I fetch with wget using the --no-check-certificate flag.

I don’t know whether you can persuade WebClient not to check certificates… but a better option would obviously be to get the certificate fixed.

Alternatively, try this URL instead: https://www.mtgox.com/code/data/ticker.php – note the www at the front. That fetches in wget without any issues.
