var loginInfo = await AuthenticationManager.GetExternalLoginInfoAsync();
if (loginInfo == null)
{
return RedirectToAction("Login");
}
loginInfo 始终为 null,我用 fiddler 检查响应,网站 (Steam) 似乎返回了正确的值

那为什么我得到的是空值?我从 SO 中遇到同样问题的人那里读了一堆线程,但到目前为止没有运气。
我们将不胜感激。
最佳答案
所以我得到 null 的原因是因为我在 Startup.Auth 的
app.CreatePerOwinContext
之前放置了 app.UseSteamAuthentication("ABCDEFGHIJKLMNOPQRSTUVWXYZ");
。 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
}
所以我把它改成:
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!
}
关于c# - ASP Identity GetExternalLoginInfoAsync 总是返回 null,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/31216874/
