要实现ASP.NET Core 8的外部登录功能,需要进行以下步骤:
安装必要的NuGet包:在项目中安装Microsoft.AspNetCore.Authentication和Microsoft.AspNetCore.Authentication.* NuGet包,例如Microsoft.AspNetCore.Authentication.Cookies和Microsoft.AspNetCore.Authentication.Google。
配置外部登录选项:在Startup.cs文件的ConfigureServices方法中添加外部登录选项配置。例如,配置Google外部登录选项:
services.AddAuthentication()
.AddGoogle(options =>
{
options.ClientId = "YourClientId";
options.ClientSecret = "YourClientSecret";
});
app.UseAuthentication();
Google登录
app.UseEndpoints(endpoints =>
{
endpoints.MapControllerRoute(
name: "default",
pattern: "{controller=Home}/{action=Index}/{id?}");
endpoints.MapControllerRoute(
name: "ExternalLoginCallback",
pattern: "signin-google",
defaults: new { controller = "Account", action = "ExternalLoginCallback" });
});
[AllowAnonymous]
public async Task ExternalLoginCallback()
{
var info = await _signInManager.GetExternalLoginInfoAsync();
if (info == null)
{
return RedirectToAction("Login");
}
// 处理外部登录用户信息
return RedirectToAction("Index", "Home");
}
var user = new ApplicationUser { UserName = info.Principal.Identity.Name };
var result = await _userManager.CreateAsync(user);
if (result.Succeeded)
{
result = await _userManager.AddLoginAsync(user, info);
if (result.Succeeded)
{
await _signInManager.SignInAsync(user, isPersistent: false);
return RedirectToAction("Index", "Home");
}
}
return RedirectToAction("Login");
以上是实现ASP.NET Core 8的外部登录功能的一般步骤和代码示例。具体的实现可能会根据外部登录提供商的要求和身份验证配置的不同而有所变化。
