[英]Why do i get 404 error when posting from form in azure app service but It works perfectly in localhost
[英]Google login works on localhost and test server, but not azure website (app service)
我在使用OWIN在Azure網站上使用Google登錄用戶時遇到問題。 一切都運行良好localhost和我們的測試服務器,但當我部署到我們的Azure網站時,登錄失敗。
我正在使用web api和OWIN來處理身份驗證,我已將其縮小到這個“簡單”問題:
await AuthenticationManager.GetExternalLoginInfoAsync();
部署到azure時返回null。
在部署到azure時有沒有人遇到過類似的問題?
更新:
以下是代碼流:首先,當用戶登錄時,我們在Startup.Auth.cs中的google提供程序上點擊“OnAuthenticated”事件:
public void ConfigureAuth(IAppBuilder app)
{
app.CreatePerOwinContext(ApplicationDbContext.Create);
app.CreatePerOwinContext<ApplicationUserManager>(ApplicationUserManager.Create);
app.CreatePerOwinContext<ApplicationSignInManager>(ApplicationSignInManager.Create);
app.UseKentorOwinCookieSaver();
var provider = new CookieAuthenticationProvider();
var originalHandler = provider.OnApplyRedirect;
app.UseCookieAuthentication(new CookieAuthenticationOptions
{
AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
LoginPath = new PathString("/Login"),
Provider = new CookieAuthenticationProvider
{
OnValidateIdentity = SecurityStampValidator.OnValidateIdentity<ApplicationUserManager, ApplicationUser>(
validateInterval: TimeSpan.FromMinutes(30),
regenerateIdentity: (manager, user) => user.GenerateUserIdentityAsync(manager)),
OnApplyRedirect = context =>
{
if (!context.Request.Uri.LocalPath.StartsWith(VirtualPathUtility.ToAbsolute("~/api")))
{
context.RedirectUri = new Uri(context.RedirectUri).PathAndQuery;
originalHandler.Invoke(context);
}
}
}
});
app.UseExternalSignInCookie(DefaultAuthenticationTypes.ExternalCookie);
app.UseTwoFactorSignInCookie(DefaultAuthenticationTypes.TwoFactorCookie, TimeSpan.FromMinutes(5));
app.UseTwoFactorRememberBrowserCookie(DefaultAuthenticationTypes.TwoFactorRememberBrowserCookie);
var options = new GoogleOAuth2AuthenticationOptions
{
ClientId = System.Configuration.ConfigurationManager.AppSettings["googleServiceAccountWebApplicationClientId"],
ClientSecret = System.Configuration.ConfigurationManager.AppSettings["googleServiceAccountWebApplicationClientSecret"],
Provider = new GoogleOAuth2AuthenticationProvider
{
OnAuthenticated = context =>
{
//....
return Task.FromResult(0);
}
},
AccessType = "offline",
SignInAsAuthenticationType = DefaultAuthenticationTypes.ExternalCookie
};
app.UseGoogleAuthentication(options);
}
在這個事件之后,我們點擊方法“ExternalLoginCallback”,我們做的第一件事就是調用await AuthenticationManager.GetExternalLoginInfoAsync(); 返回null
[AllowAnonymous]
public async Task<ActionResult> ExternalLoginCallback(string returnUrl)
{
var loginInfo = await AuthenticationManager.GetExternalLoginInfoAsync();
//loginInfo is always null when published to Azure website
if (loginInfo == null)
{
return RedirectToAction("NoAccess", "Login");
}
//....
}
我終於找到了問題。 這是“OnAuthenticated”活動中未經處理的例外。 花了一些時間才找到問題,因為這一行:
HttpContext.Current.GetOwinContext().GetUserManager<ApplicationUserManager>();
有時在天藍色上失敗。 我改變了很多代碼來嘗試找到/解決這個問題,但我確實認為這是OnAuthenticated中的一個例外。
