  我的解决方案很简单 . 我只是检查用户是否已登录并为他添加新社交 .

  public async Task<ActionResult> Callback(string provider)
      {
          var externalLoginInfo = await _applicationSignInManager.AuthenticationManager.GetExternalLoginInfoAsync();
          if (externalLoginInfo == null)
          {
              return RedirectToAction("Index", "SignIn");
          }
  
          // Check if the user with this external login provider already has a login
          if (await _applicationSignInManager.UserManager.FindAsync(externalLoginInfo.Login) != null) return RedirectToAction("Index", "Social");
  
          await _applicationSignInManager.UserManager.AddLoginAsync(HttpContext.GetOwinContext().Authentication.User.Identity.GetUserId<long>(), externalLoginInfo.Login);
  
          return RedirectToAction("Index", "Social");
      }
