一、介绍

基于鸿蒙Next模拟账号一键登录，免去账号注册环节

二、场景需求

1. 用户场景

新用户： 需要快速注册并登录，以体验华为的服务。

老用户： 希望快速登录，不用每次输入用户名和密码。

三、业务步骤

第一步：点击“一键登录”，获取登录信息

第二步：拉起授权弹窗

第三步：获取授权，获取用户信息

第四步：展示用户信息，显示功能选项

四、开发准备

配置Client ID
1.登录AppGallery Connect平台，在“我的项目”中选择目标应用，在“项目设置 > 常规 > 应用”区域获取“OAuth 2.0客户端ID（凭据）”处的Client ID。

2.在工程中entry模块的module.json5文件中，新增metadata，配置name为client_id，value为上一步获取的Client ID的值，如下所示：

配置scope权限

具体配置步骤大家可以移步官网查看配置scope权限

华为账号服务需要遵循华为登录UX设计规范。

3.导入Account Kit的authentication模块及相关公共模块

import { authentication } from '@kit.AccountKit';
import { util } from '@kit.ArkTS';
import { hilog } from '@kit.PerformanceAnalysisKit';
import { BusinessError } from '@kit.BasicServicesKit';

4.调用authentication模块的AuthorizationWithHuaweiIDRequest请求获取华为账号用户的UnionID、OpenID、匿名手机号。匿名手机号用于登录页面展示。

  getQuickLoginAnonymousPhone() {
    // 创建授权请求，并设置参数
    const authRequest = new authentication.HuaweiIDProvider().createAuthorizationWithHuaweiIDRequest();
    // 获取匿名手机号需传quickLoginAnonymousPhone这个scope，传参之前需要先申请“华为账号一键登录”权限
    authRequest.scopes = ['quickLoginAnonymousPhone'];
    // 用于防跨站点请求伪造
    authRequest.state = util.generateRandomUUID();
    // 一键登录场景该参数必须设置为false
    authRequest.forceAuthorization = false;
    const controller = new authentication.AuthenticationController();
    try {
      controller.executeRequest(authRequest).then((response: authentication.AuthorizationWithHuaweiIDResponse) => {
        // 获取到UnionID、OpenID、匿名手机号
        const unionID = response.data?.unionID;
        const openID = response.data?.openID;
        const anonymousPhone = response.data?.extraInfo?.quickLoginAnonymousPhone as string;
        if (anonymousPhone) {
          hilog.info(0x0000, 'testTag', 'Succeeded in authentication.');
          const quickLoginAnonymousPhone: string = anonymousPhone;
          return;
        }
        hilog.info(0x0000, 'testTag', 'Succeeded in authentication. AnonymousPhone is empty.');
        // 未获取到匿名手机号需要跳转到应用自定义的登录页面
      }).catch((error: BusinessError) => {
        this.dealAllError(error);
      })
    } catch (error) {
      this.dealAllError(error);
    }
  }

  // 错误处理
  dealAllError(error: BusinessError): void {
    hilog.error(0x0000, 'testTag',
      `Failed to get quickLoginAnonymousPhone, errorCode is ${error.code}, errorMessage is ${error.message}`);
  }

4.将获取到的匿名手机号设置给下面QuickLoginButtonComponent组件示例代码中的quickLoginAnonymousPhone变量，调用LoginWithHuaweiIDButton组件，实现应用自己的登录页面，并展示华为账号一键登录按钮和华为账号用户认证协议（Account Kit提供跳转链接，应用需实现协议跳转，参见约束与限制第2点），用户同意协议并点击一键登录按钮后，可获取到Authorization Code，将该值传给应用服务器用于获取用户信息（完整手机号、UnionID、OpenID）。

import { loginComponentManager, LoginWithHuaweiIDButton } from '@kit.AccountKit';
import { hilog } from '@kit.PerformanceAnalysisKit';
import { BusinessError } from '@kit.BasicServicesKit';

import { connection } from '@kit.NetworkKit';

@Component
struct QuickLoginButtonComponent {
  logTag: string = 'QuickLoginButtonComponent';
  domainId: number = 0x0000;
  // 第二步获取的匿名化手机号传到此处
  @State quickLoginAnonymousPhone: string = '';
  // 是否勾选协议
  @State isSelected: boolean = false;

  private static PRIVACY_TAG = '隐私协议';
  private static USER_AUTHENTICATION_TAG = '华为账号用户认证协议';
  // 定义LoginWithHuaweiIDButton展示的隐私文本，展示应用的用户服务协议、隐私协议和华为账号用户认证协议
  privacyText: loginComponentManager.PrivacyText[] = [{

      /**
