我正在尝试使用表单身份验证使用WP7(Mango)模拟器登录我的作品网站。 (最终创建一个WP7应用程序,让您查看此站点上的一些内容)
网站webconfig包含:
<system.web.extensions>
<scripting>
<webServices>
<authenticationService enabled="true" requireSSL="false"/>
</webServices>
</scripting>
他们有示例代码,基本上通过调用身份验证ODataService登录,传入user / pass并获取身份验证cookie。
使用此cookie,所有新请求都将其包含在ODataService中,并且应该能够检索数据。
在发出任何请求之前 - 获取身份验证Cookie
private static string GetAuthenticationCookie(string username, string password)
{
if (authenticationCookie == null)
{
string loginServiceAddress = websiteUrl + "/Authentication_JSON_AppService.axd/Login";
var request = CreateAuthenticationRequest(username, password, loginServiceAddress);
var response = request.GetResponse();
if (response.Headers["Set-Cookie"] != null)
{
authenticationCookie = response.Headers["Set-Cookie"];
}
else
{
throw new SecurityException("Invalid credentials");
}
}
return authenticationCookie;
}
private static WebRequest CreateAuthenticationRequest(string username, string password, string loginServiceAddress)
{
var request = HttpWebRequest.Create(loginServiceAddress);
request.Method = "POST";
request.ContentType = "application/json";
var body = string.Format(
"{{ \"userName\": \"{0}\", \"password\": \"{1}\", \"createPersistentCookie\":false}}",
username,
password);
request.ContentLength = body.Length;
var stream = request.GetRequestStream();
using (var sw = new StreamWriter(stream))
{
sw.Write(body);
}
return request;
}
我不能将此代码复制粘贴到Windows Phone 7.1(Mango)应用程序中,因为网络代码略有不同 - 例如......所有内容都在WP7中异步完成,如
myWebRequest.GetResponse()
不再有效......我必须做类似
的事情myWebRequest.BeginGetResponse()
如果有人在WP7中使用表单auth进行身份验证的任何工作代码示例 - 这将是很好的
非常感谢

查看此http类:
http://mytoolkit.codeplex.com/wikipage?title=Http
以下代码可以解决这个问题:
private void OnButtonClick(object sender, RoutedEventArgs e)
{
const string username = "user";
const string password = "password";
const string loginServiceAddress = "http://www.server.com/Services/AuthenticationService.svc";
var text = string.Format("{{ \"userName\": \"{0}\", \"password\": \"{1}\", \"createPersistentCookie\":false}}",
username, password);
var request = new HttpPostRequest(loginServiceAddress);
request.RawData = Encoding.UTF8.GetBytes(text);
request.ContentType = "application/json";
Http.Post(request, AuthenticationCompleted);
}
private void AuthenticationCompleted(HttpResponse authResponse)
{
const string serviceAddress = "http://www.server.com";
if (authResponse.Successful)
{
var sessionCookie = authResponse.Cookies.Single(c => c.Name == "SessionId");
var request = new HttpGetRequest(serviceAddress);
request.Cookies.Add(new Cookie("SessionId", sessionCookie.Value));
Http.Get(request, OperationCallCompleted);
}
}
private void OperationCallCompleted(HttpResponse response)
{
if (response.Successful)
{
// TODO: do your parsing
var responseText = response.Response;
Deployment.Current.Dispatcher.BeginInvoke(() =>
{
// TODO: set data to binding or directly to user control (in UI thread)
});
}
}
