[英]External Authentication with ASP.NET Web API 2 - Microsoft not working now
[英]External Authentication ASP.NET Web API
我有Web API和在單獨的解決方案中調用Web API的客戶端。 我需要使用現有用戶數據的本地身份驗證來對用戶進行身份驗證,還需要使用Google和Facebook等外部身份驗證來進行身份驗證。
本地身份驗證工作正常。 但是在對外部登錄進行身份驗證時,調用api / Account / UserInfo時得到未經授權的響應。 請注意,我能夠從Google帳戶正確生成令牌。
這是我的AccountController.cs文件。

這是StartUp.Auth.cs文件中的ConfigureAuth方法
public void ConfigureAuth(IAppBuilder app)
{
// Configure the db context and user manager to use a single instance per request
app.CreatePerOwinContext(ApplicationDbContext.Create);
app.CreatePerOwinContext<ApplicationUserManager>(ApplicationUserManager.Create);
// Enable the application to use a cookie to store information for the signed in user
// and to use a cookie to temporarily store information about a user logging in with a third party login provider
app.UseCookieAuthentication(new CookieAuthenticationOptions());
app.UseExternalSignInCookie(DefaultAuthenticationTypes.ExternalCookie);
app.UseCors(Microsoft.Owin.Cors.CorsOptions.AllowAll);
// Configure the application for OAuth based flow
PublicClientId = "self";
OAuthOptions = new OAuthAuthorizationServerOptions
{
TokenEndpointPath = new PathString("/Token"),
Provider = new ApplicationOAuthProvider(PublicClientId),
AuthorizeEndpointPath = new PathString("/api/Account/ExternalLogin"),
AccessTokenExpireTimeSpan = TimeSpan.FromDays(14),
// In production mode set AllowInsecureHttp = false
AllowInsecureHttp = true
};
// Enable the application to use bearer tokens to authenticate users
app.UseOAuthBearerTokens(OAuthOptions);
// Uncomment the following lines to enable logging in with third party login providers
//app.UseMicrosoftAccountAuthentication(
// clientId: "",
// clientSecret: "");
//app.UseTwitterAuthentication(
// consumerKey: "",
// consumerSecret: "");
var facebookoptions = new FacebookAuthenticationOptions()
{
AppId = "",
AppSecret = "",
BackchannelHttpHandler = new FaceBookBackChannelHandler(),
UserInformationEndpoint = "https://graph.facebook.com/v2.4/me?fields=email,first_name,last_name,gender"
};
facebookoptions.Scope.Add("email");
app.UseFacebookAuthentication(facebookoptions);
//app.UseFacebookAuthentication(
// appId: "",
// appSecret: "");
app.UseGoogleAuthentication(new GoogleOAuth2AuthenticationOptions()
{
ClientId = "",
ClientSecret = ""
});
}
這也是調用API端點的jQuery方法
function getAccessToken() {
if (location.hash) {
if (location.hash.split('access_token=')) {
var accessToken = location.hash.split('access_token=')[1].split('&')[0];
if (accessToken) {
isUserRegistered(accessToken);
}
}
}
}
function isUserRegistered(accessToken) {
$.ajax({
url: 'http://localhostXXXX/api/Account/UserInfo',
method: 'GET',
cors:
{
headers: {
'content-type': 'application/JSON',
'Authorization': 'Bearer ' + accessToken
}
},
success: function (response) {
if (response.HasRegistered) {
localStorage.setItem('accessToken', accessToken);
localStorage.setItem('userName', response.Email);
window.location.href = "Data.aspx";
}
else {
signupExternalUser(accessToken);
}
}
});
}
function signupExternalUser(accessToken) {
$.ajax({
url: 'http://localhost:XXXXX/api/Account/RegisterExternal',
method: 'POST',
cors:
{
headers: {
'content-type': 'application/json',
'Authorization': 'Bearer ' + accessToken
}
},
success: function () {
window.location.href = "";
}
});
}
這是我用來獲取信息的代碼。 它的工作很好:
// check if authorized
if (Request["code"] == null)
{
Response.Redirect(string.Format(
"https://graph.facebook.com/oauth/authorize?client_id={0}&redirect_uri={1}&scope={2}",
app_id, Request.Url.AbsoluteUri, scope));
}
else
{
FacebookAccessToken token = new FacebookAccessToken();
FacebookUser user = new FacebookUser();
//Requesting for access token
string url = string.Format("https://graph.facebook.com/oauth/access_token?client_id={0}&redirect_uri={1}&scope={2}&code={3}&client_secret={4}",
app_id, Request.Url.AbsoluteUri, scope, Request["code"].ToString(), app_secret);
HttpWebRequest request = WebRequest.Create(url) as HttpWebRequest;
using (HttpWebResponse response = request.GetResponse() as HttpWebResponse)
{
StreamReader reader = new StreamReader(response.GetResponseStream());
string vals = reader.ReadToEnd();
// Deserialize json object
token = JsonConvert.DeserializeObject<FacebookAccessToken>(data);
}
//Getting user info
url = string.Format("https://graph.facebook.com/v2.8/me?access_token={0}", token.AccessToken);
request = WebRequest.Create(url) as HttpWebRequest;
using (var client = request.GetResponse() as HttpWebResponse)
{
StreamReader reader = new StreamReader(client.GetResponseStream());
string data = reader.ReadToEnd();
// data:"{\"name\":\"Er Vatsal D Patel\",\"id\":\"13168723650*****\"}";
user = JsonConvert.DeserializeObject<FacebookUser>(data);
}
return "done";
