Jquery Can'；t解析LoginService:5的所有参数

一、 我是新来的。尝试解决此问题时，无法解决LoginService的所有参数

这是我的登录服务类

import { Injectable } from '@angular/core';
import { LoginViewModel as loginVM } from "../../viewmodel/app.login.viewmodel"
import { Data as LoginVmData } from '../../viewmodel/app.loginVm'
import { HttpClient, HttpHeaders } from "@angular/common/http";
import { Observable } from 'rxjs';
@Injectable()
export class LoginService {

    private loginUrl = "Account/Authentication";
    private registerUrl = "Account/Registration";

    private _httpClientModule: HttpClient;
    private _loginVmData: LoginVmData;

    constructor(httpClientModule: HttpClient, loginVmData: LoginVmData ) {
        this._httpClientModule = httpClientModule;
        this._loginVmData = loginVmData;
    }


    public LoginHttpCall(): Observable<loginVM> {

        const headers = new HttpHeaders().set('Content-Type', 'application/json; charset=utf-8');

        return this._httpClientModule.post<loginVM>(this.loginUrl, this._loginVmData, { headers });
    }

    public registerHttpCall(_loginVM: LoginVmData): Observable<loginVM> {

        const headers = new HttpHeaders().set('Content-Type', 'application/json; charset=utf-8');

        return this._httpClientModule.post<loginVM>(this.registerUrl, _loginVM, { headers });
    }

}

APP.Shared.Module

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { FormsModule } from '@angular/forms';
import { HttpClientModule } from '@angular/common/http';
import { RouterModule } from '@angular/router';
import { AppComponent } from './components/app/app.component';
import { EqualValidator } from "./components/Validation/equal.validator.directive";
import { HomeComponent } from './components/home/home.component';
import { LoginComponent } from './components/usercreation/login.component';
import { MobileComponent } from './components/mobile/mobile.component';
import { SocialComponent } from './components/usercreation/social.component';
import { RegisterComponent } from './components/usercreation/signup.component';
import { DashBoardComponent } from './components/dashboard/dashboard.component';

@NgModule({
    declarations: [
        AppComponent, RegisterComponent, EqualValidator, DashBoardComponent,
        HomeComponent,
        LoginComponent,
        MobileComponent,
        SocialComponent
    ],
    imports: [
        CommonModule,
        HttpClientModule,
        FormsModule,
        RouterModule.forRoot([
            { path: '', redirectTo: 'home', pathMatch: 'full' },
            { path: 'home', component: HomeComponent },
            { path: 'login', component: LoginComponent },
            { path: 'mobile', component: MobileComponent },
            { path: 'dashboard', component: DashBoardComponent },
            { path: 'signup', component: RegisterComponent },
            { path: '**', redirectTo: 'home' }
        ])
    ]
})
export class AppModuleShared {
}

最后一个App.Component.ts

import { Component } from '@angular/core';
import { DashBoardComponent } from "../../components/dashboard/dashboard.component";
import { LoginViewModel } from "../../viewmodel/app.login.viewmodel";
@Component({
    selector: 'app',
    templateUrl: './app.component.html',
    styleUrls: ['./app.component.css'],

})
export class AppComponent {
    public menulist: boolean = true;
    private _dashBoard: DashBoardComponent;
    public _loginVM: LoginViewModel;
    constructor(loginVm: LoginViewModel, dashboard: DashBoardComponent) {
        this.menulist = true;
        this._dashBoard = dashboard;
        this._loginVM = loginVm;
    }
    ngOnInit() {
        this.menulist = true;

    }
}

我正在创建的循环依赖关系在哪里？我无法理解

请给我一些帮助。我将Angular 5与asp.net core 2.0一起使用问题与

登录服务中的
loginVmData:loginVmData
有关。DI在尝试注入时无法检测到它是什么。关于这一点，你可以阅读

但是

查看您的代码，您只是将此数据传递到
LoginHttpCall
服务中。因此，您可以将其从构造函数中删除，并使该方法接受此数据，类似于
registerhtpcall
方法。在方法中传递登录模型，而不是将其注入构造函数

constructor(httpClientModule: HttpClient ) {
   this._httpClientModule = httpClientModule;
}

public LoginHttpCall(loginVmData: LoginVmData): Observable<loginVM> {    
   const headers = new HttpHeaders().set('Content-Type', 'application/json; charset=utf-8');    
   return this._httpClientModule.post<loginVM>(this.loginUrl, loginVmData, { headers });
}

构造函数（httpClientModule:HttpClient）{
这是.\u httpClientModule=httpClientModule；
}
公共LoginHttpCall（loginVmData:loginVmData）：可观察{
const headers=new-HttpHeaders（）.set（'Content-Type'，'application/json；charset=utf-8'）；
返回此.httpClientModule.post（this.loginUrl，loginVmData，{headers}）；
}
您在app.loginVm.ts文件中导入了任何东西吗？为什么要在另一个组件类中注入组件？！你能提供更多关于你想做什么的信息吗
constructor(httpClientModule: HttpClient ) {
   this._httpClientModule = httpClientModule;
}

public LoginHttpCall(loginVmData: LoginVmData): Observable<loginVM> {    
   const headers = new HttpHeaders().set('Content-Type', 'application/json; charset=utf-8');    
   return this._httpClientModule.post<loginVM>(this.loginUrl, loginVmData, { headers });
}
