input绑定：
@H_502_2@要先在app.Module中导入FormModule，否则会Console会报错：Can’t bind to ‘ngModel’ since it isn’t a known property of ‘input’
import { FormsModule } from '@angular/forms';
@NgModule({
imports: [...
FormsModule,....参考
<form class="form-inline">
<div class="form-group">
<label class="sr-only" for="inputNickName">NickName</label>
<div class="input-group">
<div class="input-group-addon">昵称:</div>
<input type="text" class="form-control" id="inputNickName" [(ngModel)]="nickName" placeholder="NickName">
<!--<input [(ngModel)]="nickName"> <input [value]="nickName" (input)="nickName = $event.target.value">-->
</div>
</div>
<button type="button" class="btn btn-primary" (click)="Login()">进入聊天室</button>
</form>
运行后显示正常，但F12 Console会报错：
If ngModel is used within a form tag,either the name attribute must be set or the form control must be defined as ‘standalone’ in ngModelOptions.

在一个form标签中使用f ngModel，必须设置name属性，或者在ngModelOptions中必须将表单控件定义为“standalone”。[ngModelOptions]=”{standalone: true}”
<input type="text" class="form-control" id="inputNickName" [(ngModel)]="nickName" name="NickName placeholder="NickName">
<!--或-->
<input type="text" class="form-control" id="inputNickName" [(ngModel)]="nickName" [ngModelOptions]="{standalone: true}" placeholder="NickName">
Angular使用toastr，消息提示插件。
@H_502_2@'ngx-toastr': 'npm:_ngx-toastr@8.1.0@ngx-toastr/toastr.umd.js'
@H_502_2@
Angular版本升级
@H_502_2@httpService
@H_502_2@angular_cli取代systemjs
@H_502_2@systemjs的配置文件是system.config.js，angular_cli的配置文件是 .angular-cli.json，app的index要添加什么都在.angular-cli.json中配置了。angular-cli的web开发前后端的分离开发，刚用起来有点别扭，不知道怎么弄？查看 从MVC到前后端分离。
@H_502_2@
ng build
6. iis上新建网站，并浏览。
7. **如果是部署在现有IIS网站下的虚拟目录，必须删除index.html中的下面一段，否则js基本、图等资料会找不到。

8. Hehe，眼睛一下就亮了，总算有头绪了。

重写以上
@H_502_2@@H_502_2@
npm uninstall -g angular-clinpm cache clean （--forced）npm install -g @angular/cli@latest`ng -v@H_502_2@
npm uninstall --save-dev angular-clinpm install --save-dev @angular/cli@latestnpm install按2 重新安装bootstrap，安装提示ootstrap@next有依赖没安装。
cnpm install ngx-bootstrap bootstrap@next --save
安装依赖。
cnpm install popper.jscnpm install jquery@1.9.1
ng serve 运行后总是不显示boostrap的样式，是因为用的cnpm安装的，使用cnpm安装的在.angular.cli.json 的Styles配置要带版本。参考。原因是：简单来说，npminstall 下的 node_modules 目录采用和 npm 官方 client 不一样的布局，主要是为了最大限度提高安装速度。参见1，2。
cnpm安装第三方插件 .angular-cli.json引用
