Download google font api with C#

Question

I have a google api font from this Url: https://fonts.googleapis.com/css?family=Montserrat

When I use the browser to view, it renders these css:

/* cyrillic-ext */
@font-face {
  font-family: 'Montserrat';
  font-style: normal;
  font-weight: 400;
  src: local('Montserrat Regular'), local('Montserrat-Regular'), url(https://fonts.gstatic.com/s/montserrat/v12/rBHvpRWBkgyW99dXT88n7yEAvth_LlrfE80CYdSH47w.woff2) format('woff2');
  unicode-range: U+0460-052F, U+1C80-1C88, U+20B4, U+2DE0-2DFF, U+A640-A69F, U+FE2E-FE2F;
}
/* cyrillic */
@font-face {
  font-family: 'Montserrat';
  font-style: normal;
  font-weight: 400;
  src: local('Montserrat Regular'), local('Montserrat-Regular'), url(https://fonts.gstatic.com/s/montserrat/v12/NX1NravqaXESu9fFv7KuqiEAvth_LlrfE80CYdSH47w.woff2) format('woff2');
  unicode-range: U+0400-045F, U+0490-0491, U+04B0-04B1, U+2116;
}
/* vietnamese */
@font-face {
  font-family: 'Montserrat';
  font-style: normal;
  font-weight: 400;
  src: local('Montserrat Regular'), local('Montserrat-Regular'), url(https://fonts.gstatic.com/s/montserrat/v12/SKK6Nusyv8QPNMtI4j9J2yEAvth_LlrfE80CYdSH47w.woff2) format('woff2');
  unicode-range: U+0102-0103, U+0110-0111, U+1EA0-1EF9, U+20AB;
}
/* latin-ext */
@font-face {
  font-family: 'Montserrat';
  font-style: normal;
  font-weight: 400;
  src: local('Montserrat Regular'), local('Montserrat-Regular'), url(https://fonts.gstatic.com/s/montserrat/v12/gFXtEMCp1m_YzxsBpKl68iEAvth_LlrfE80CYdSH47w.woff2) format('woff2');
  unicode-range: U+0100-024F, U+0259, U+1E00-1EFF, U+20A0-20AB, U+20AD-20CF, U+2C60-2C7F, U+A720-A7FF;
}
/* latin */
@font-face {
  font-family: 'Montserrat';
  font-style: normal;
  font-weight: 400;
  src: local('Montserrat Regular'), local('Montserrat-Regular'), url(https://fonts.gstatic.com/s/montserrat/v12/zhcz-_WihjSQC0oHJ9TCYPk_vArhqVIZ0nv9q090hN8.woff2) format('woff2');
  unicode-range: U+0000-00FF, U+0131, U+0152-0153, U+02BB-02BC, U+02C6, U+02DA, U+02DC, U+2000-206F, U+2074, U+20AC, U+2122, U+2212, U+2215;
}

But when I download it using c# WebClient:

WebClient client = new WebClient();
string downloadString = client.DownloadString("https://fonts.googleapis.com/css?family=Montserrat");

It only returns:

@font-face {
  font-family: 'Montserrat';
  font-style: normal;
  font-weight: 400;
  src: local('Montserrat Regular'), local('Montserrat-Regular'), url(https://fonts.gstatic.com/s/montserrat/v12/zhcz-_WihjSQC0oHJ9TCYC3USBnSvpkopQaUR-2r7iU.ttf) format('truetype');
}

I know google font api renders different definition based on browser type. I have also defined User-Agent as Chrome browser but still no difference.

request.UserAgent = "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.17 (KHTML, like Gecko) Chrome/24.0.1312.57 Safari/537.17";

So how can I get the same result as I see it in browser?

Answer 1

I suspect your method of setting the user agent wasn't correct. This works fine for me...

var url = "https://fonts.googleapis.com/css?family=Montserrat";
var filename = @"c:\temp\montserrat.css";
var userAgent = "Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/63.0.3239.84 Safari/537.36";

using (var client = new WebClient())
{
    client.Headers.Add("user-agent", userAgent);
    client.DownloadFile(url, filename);
}
