abp Vnext OpenIddect 扩展微信小程序授权登录,ABP VNEXT,微信小程序,.netcore,ABP Vnext,OpenIddict

abp vnext6.0之后官方替换了原来的ids4，采用了openIddict的oauth认证框架。使用之前的方法已经不行，以下是OpenIddect 使用ITokenExtensionGrant接口进行的授权登入扩展，按照以下代码可实现，欢迎交流指正。

新建用于接收微信返回数据字段类

public class Results
{
  /// <summary>
  /// 用户唯一标识
  /// </summary>
  public string openid { get; set; }
  /// <summary>
  /// 会话密钥
  /// </summary>
  public string session_key { get; set; }
  /// <summary>
  /// 用户在开放平台的唯一标识符，若当前小程序已绑定到微信开放平台帐号下会返回
  /// </summary>
  public string unionid { get; set; }
  /// <summary>
  /// 错误码
  /// </summary>
  public int errcode { get; set; }
  /// <summary>
  /// 错误信息
  /// </summary>
  public string  errmsg { get; set; } 
}

在HttpApi.Host新建类

using Microsoft.AspNetCore.Identity;

            else 
            {
                return new Results { errmsg = "微信接口请求失败" };
            }
        }
    }
}

在HttpApiHostModule.cs 文件中添加注册

使用上面定义的ExtensionGrantName扩展的这个openiddict的认证流程的名字

public override void PreConfigureServices(ServiceConfigurationContext context)
    {
        ///······
        PreConfigure<OpenIddictServerBuilder>(builder =>
        {
            builder.Configure(options =>
            {
                options.GrantTypes.Add(Demo.ExtensionGrantName);
            });
        });
    }

请求地址和参数

host:/connect/token
methon:POST
media type:aplication/x-www-form-urlencoded
body:
	grant_type=wechat_code
	code=微信小程序提供的code
	client_id=自己项目的client_id
	scope=自己项目 openid offline_access
