Custom User Agent for a WebView

问题

can I set a custom User Agent for a WebView?

I need to show mobile style of websites.

回答1:

It's easy to do:

string ua = "Mozilla/5.0 (iPhone; CPU iPhone OS 6_0 like Mac OS X)" + "AppleWebKit/536.26 (KHTML, like Gecko) Version/6.0 Mobile/10A5376e Safari/8536.25";
var httpRequestMessage = new HttpRequestMessage(HttpMethod.Get, new Uri(url));
httpRequestMessage.Headers.Add("User-Agent",ua);
webView1.NavigateWithHttpRequestMessage(hrm);

回答2:

Per this MSDN Forum posting you cannot. Could you host a lightweight proxy service (say Azure Web Site) to proxy the request for you?

You can load HTML with custom user agent and then pass the html to WebView

Loading html

var handler = new HttpClientHandler {AllowAutoRedirect = false};
var client = new HttpClient(handler);
client.DefaultRequestHeaders.Add("user-agent",
                                 "Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.2; 
                                  WOW64; Trident/6.0)");
var response = await client.GetAsync(url);
response.EnsureSuccessStatusCode();
var html = await response.Content.ReadAsStringAsync();

assign html to WebView

WebView.NavigateToString(html);
