如何使用PCL的HttpWebRequest禁用AllowAutoRedirect

Question

I'm rewriting my WP7's lib to PCL. I have a function which uses HttpWebRequest's AllowAutoRedirect = false; property. It's very important for correct log-in. I was disappointed when tried just copy-paste this function to PCL project.

Error   1   'System.Net.HttpWebRequest' does not contain a definition for 'AllowAutoRedirect' and no extension method 'AllowAutoRedirect' accepting a first argument of type 'System.Net.HttpWebRequest' could be found (are you missing a using directive or an assembly reference?)

Is any workaround how to fix it?

Answer 1

You cannot do this in your PCL project if it targets Windows Phone 7. You can however create a Windows Phone 7 Library with Visual Studio Express 2010 for Windows Phone:

You can still keep your code in the PCL and just inject the HttpWebrequest from the Windows Phone 7 library project. I know it's messy but it may be the only way to accomplish it without having to have duplicate libraries for different platforms.

I've found solution on msdn forums but need to install portable http cline library from nuget first:

Install-Package Microsoft.Net.Http

Here is peace of my modified code.

HttpClientHandler hch = new HttpClientHandler();
hch.AllowAutoRedirect = false;
HttpClient hc = new HttpClient(hch);

StringContent queryString = new StringContent(string.Format("login={0}&password={1}", Uri.EscapeUriString(username), Uri.EscapeUriString(password));
queryString.Headers.ContentType = new System.Net.Http.Headers.MediaTypeHeaderValue("application/x-www-form-urlencoded");

HttpResponseMessage msg = await hc.PostAsync("http://www....", queryString);
string responseBody = await msg.Content.ReadAsStringAsync();
...

Hope it will help to somebody
