是的，abp.io支持“使用Google登录”按钮。在abp.io中，您可以使用IdentityServer插件来实现此功能。您需要做的是在IdentityServer的配置文件（appsettings.json）中添加Google作为身份验证提供程序，并在您的前端代码中使用Google按钮。以下是一个示例：

1.在IdentityServer的配置文件（appsettings.json）中添加Google作为身份验证提供程序

"IdentityServer": {
   "Clients": {
       //...其他客户端配置
      "MyClient": {
         //...其他客户端配置
         "ClientId": "my_client_id",
         "ClientSecrets": [{
            "Value": "my_client_secret"
         }],
         "AllowedGrantTypes": [ "client_credentials", "authorization_code", "implicit", "password" ],
         "RedirectUris": [ "https://localhost:4200/signin-oidc" ],
         "PostLogoutRedirectUris": [ "https://localhost:4200/signout-callback-oidc" ],
         "AllowedScopes": [ "openid", "profile", "my_api" ]
      }
   },
   "IdentityProviders": {
      "Google": {
         "ClientId": "my_google_client_id",
         "ClientSecret": "my_google_client_secret"
      }
   }
}

2.在前端代码中使用Google按钮来登录

使用Google登录

import { Component, OnInit } from '@angular/core';
import { AuthService } from '@abp/ng.core';

@Component({
  selector: 'app-login',
  templateUrl: './login.component.html',
  styleUrls: ['./login.component.scss']
})
export class LoginComponent implements OnInit {

  constructor(private authService: AuthService) { }

  ngOnInit(): void {
  }

  startGoogleLogin() {
      this.authService.redirectToProvider('Google');
  }

}
