帮我把第三部分register.component.ts的代码补全，要具体代码，注释掉的是我写的运行出错的代码，实在没有思路写不出来了，要具体代码，功能就是注册用户

--------------------------register.service.ts
@Injectable({
    providedIn: 'root',
})
export class RegisterService {
    constructor(private httpClient: HttpClient) { }

    /**
     * 登录

     * @param {string} grade
     * @param {string} interest

        this.service.register(userName, password, email, birthday, gender, grade,
            interest, introduction, validStartTime).subscribe((result: HttpResult) => {
                // if (result.status !== HttpResultStatus.SUCCESS) {

报什么错误，代码中用到HttpResultStatus 对象，用下面的语句导入了没用？

import { HttpResultStatus } from '../constants/http-result-status.constant';
