最快的方式是直接nuget安装AspNetCore.Authentication.WeChat包。

想要知道是如何实现的，可以看下面github上面的源码。

源码在这里：[https://github.com/china-live/QQConnect][https_github.com_china-live_QQConnect]

使用方式：

1.  安装nuget的包以后，在startup.cs中添加微信授权认证并配置appId和AppSecret，使用缓存保存State数据（微信State Too Long 报错 由于微信的设置，state最多128字节，但是默认生成的state会超出限制，所以需要加入缓存）
    
        iservices.AddAuthentication().AddWeChat(options =>
                    {
                        options.AppId = Configuration["WeixinSetting:WeixinAppId"];
                        options.AppSecret = Configuration["WeixinSetting:WeixinAppSecret"];
                        options.UseCachedStateDataFormat = true;
                    });
2.  新建一个Controller，编写action
    
        /// <summary>
                /// 微信授权登录
                /// </summary>
                /// <param name="returnUrl">用户尝试进入的需要登录的页面</param>
                /// <returns></returns>
                [AllowAnonymous]
                public ActionResult WxLogin(string returnUrl)
                {
        
                    string redirectUrl = Url.Action("BaseCallback",
                        new { ReturnUrl = returnUrl });
        
                    var properties = signInManager
                        .ConfigureExternalAuthenticationProperties("WeChat", redirectUrl);
                    return new ChallengeResult("WeChat", properties);
                }
        
                /// <summary>
                /// 回调
                /// </summary>
                /// <param name="provider"></param>
                /// <param name="returnUrl">用户最初尝试进入的页面</param>
                /// <returns></returns>
                [AllowAnonymous]
                public async Task<IActionResult> BaseCallback(string provider = null, string returnUrl = "/")
                {
                    try
                    {
                        ExternalLoginInfo info = await signInManager.GetExternalLoginInfoAsync();
                        if (info == null)
                        {
                            return RedirectToAction(nameof(Login));
                        }
                        var result = await signInManager.ExternalLoginSignInAsync(
                            info.LoginProvider, info.ProviderKey, false);
                        if (result.Succeeded)
                        {
                            return Redirect(returnUrl);
                        }
                        else
                        {
                            Account user = new Account
                            {
                                OpenId = info.Principal.FindFirst(ClaimTypes.NameIdentifier).Value,
                                UserName =
                                    info.Principal.FindFirst(ClaimTypes.NameIdentifier).Value
                            };
                            IdentityResult identResult = await userManager.CreateAsync(user);
                            if (identResult.Succeeded)
                            {
                                identResult = await userManager.AddLoginAsync(user, info);
                                if (identResult.Succeeded)
                                {
                                    await signInManager.SignInAsync(user, false);
                                    return Redirect(returnUrl);
                                }
                            }
                            return AccessDenied();
                        }
                    }
                    catch (Exception ex)
                    {
               
                        return Content("发生错误：" + ex);
                    }
                }
