Question

var loginInfo = await AuthenticationManager.GetExternalLoginInfoAsync();
if (loginInfo == null)
{
     return RedirectToAction("Login");
}

loginInfo始终为null，我用fiddler检查响应，似乎网站（Steam）返回正确的值

"response": {
        "players": [
            {
                "steamid": "76561198057961078",
                "communityvisibilitystate": 3,
                "profilestate": 1,
                "personaname": "Press \"R\" to restart™",
                "lastlogoff": 1435947642,
                "commentpermission": 2,

                "personastateflags": 0
            }
        ]

    }

为什么我会变空？我从那些有相同问题的人那里读了一堆帖子但到目前为止没有运气。

任何帮助将不胜感激。

所以我得到null的原因是因为我在app.UseSteamAuthentication("ABCDEFGHIJKLMNOPQRSTUVWXYZ");之前app.CreatePerOwinContext放了Startup.Auth.cs

public void ConfigureAuth(IAppBuilder app)
{
    app.UseSteamAuthentication("ABCDEFGHIJKLMNOPQRSTUVWXYZ"); //if you put it here, it won't work
    // Configure the db context, user manager and signin manager to use a single instance per request
    app.CreatePerOwinContext(ApplicationDbContext.Create);
    app.CreatePerOwinContext<ApplicationUserManager>(ApplicationUserManager.Create);
    app.CreatePerOwinContext<ApplicationSignInManager>(ApplicationSignInManager.Create);

    //rest of the code here
}

因此我将其更改为：

public void ConfigureAuth(IAppBuilder app)
{
    // Configure the db context, user manager and signin manager to use a single instance per request
    app.CreatePerOwinContext(ApplicationDbContext.Create);
    app.CreatePerOwinContext<ApplicationUserManager>(ApplicationUserManager.Create);
    app.CreatePerOwinContext<ApplicationSignInManager>(ApplicationSignInManager.Create);

    //rest of the code here
    app.UseSteamAuthentication("ABCDEFGHIJKLMNOPQRSTUVWXYZ"); //works!
}

ASP Identity GetExternalLoginInfoAsync始终返回null
