[default] new-user.component.ts:21:4 中的错误提供的参数与调用目标的任何签名都不匹配

Question

我正在阅读 angular-for-rails- 开发人员的书，现在 'Getting Angular2-Token to register a user'

我的新-user.component.ts和app.module.ts与书中的相符。关于我遗漏的任何想法？

代码如下： app.module.ts:

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms';
import { HttpModule } from '@angular/http';

import { Angular2TokenService } from 'angular2-token';

import { HomeLibraryRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';
import { NewUserComponent } from './new-user/new-user.component';

@NgModule({
  declarations: [
    AppComponent,
    NewUserComponent
  ],
  imports: [
    BrowserModule,
    FormsModule,
    HttpModule,
    HomeLibraryRoutingModule
  ],
  providers: [Angular2TokenService],
  bootstrap: [AppComponent]
})
export class AppModule { }

new-user/new-user.component.ts

import { Component, OnInit } from '@angular/core';
import { Angular2TokenService  } from 'angular2-token';

@Component({
  selector: 'app-new-user',
  templateUrl: './new-user.component.html',
  styleUrls: ['./new-user.component.css']
})
export class NewUserComponent implements OnInit {

  constructor(private _tokenService: Angular2TokenService) {
    this._tokenService.init({
      registerAccountPath: '/api/auth'
    });
  }

  ngOnInit() {
  }

  register() {
    this._tokenService.registerAccount(
      'test@example.com',
      'password',
      'password'
    );
  }
}

在 webstorm 中，_tokenService init 和 registerAccount 方法被列为未解决。

Answer 1

试试这个：

  register() {
    this._tokenService.registerAccount({
      email: 'test@example.com',
      password: 'password',
      passwordConfirmation: 'password'
    });
  }
