我正在尝试测试angular2双向绑定以进行控制input.这是错误:

Can't bind to 'ngModel' since it isn't a known property of 'input'.

app.component.html

<input id="name" type="text" [(ngModel)]="name" />
<div id="divName">{{name}}</div>

app.component.ts

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html'  
})
export class AppComponent implements OnInit {
  name: string;    
}

app.component.spec.ts

import { TestBed, async } from '@angular/core/testing';
import { AppComponent } from './app.component';
import { AppService } from './app.service';
describe('App: Cli', () => {
  beforeEach(() => {
    TestBed.configureTestingModule({
      declarations: [
        AppComponent
      ],
      providers:[AppService]
    });
  });

  it('divName', async(() => {
    let …

我将通过https://angular.io/docs/ts/latest/tutorial/toh-pt5.html上的Angular2教程 .一切顺利的路由.Visual Studio代码显示前03行的错误:

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

如

[ts] 
Module '"c:/Users/ktran/Source/Repos/angular2-quickstart-ts/node_modules/@angular/core/index"' has no exported member 'NgModule'.

文件夹node_modules:

我正在测试从 Angular 到 Cognito 用户池的 AWS Amplify，如下所示：

我正在尝试通过 AzureAD 使用 OAuth2 来保护 APIM API，方法是阅读以下文章：通过使用 Azure AD 的 OAuth 2.0 授权保护 Azure API 管理中的 Web API 后端

AzureAPIM - OAuth2

• 授权终结点 URL (v1)：https://login.microsoftonline.com/ {tenant}/oauth2/authorize
• 令牌终结点 URL (v1)：https://login.microsoftonline.com/{tenant }/oauth2/token
• 客户端 ID：客户端应用程序 ID
• 重定向 URI：（已弃用的门户）：https ://xxx-api.portal.azure-api.net/docs/services/auth1/console/oauth2/authorizationcode/callback

AzureAD - 后端应用程序：

• 范围：文件.全部

AzureAD - 客户端应用程序：

• 密钥：xxx
• 重定向 url：仅适用于 APIM 中已弃用的门户 ( https://xxx-api.portal.azure-api.net/docs/services/auth1/console/oauth2/authorizationcode/callback )

对于演示会议 API，将验证 JWT 策略添加到入站处理，其中3a0cf09b-是租户 id，b7c31179-是后端应用程序应用程序 id：

在开发人员门户中，AzureAD 身份验证成功并返回令牌：

但是调用API授权失败：

检查 jwt.io 中收到的令牌，我发现"aud": "00000003-0000-0000-c000-000000000000"不是后端应用程序应用程序 ID：

  "aud": "00000003-0000-0000-c000-000000000000",

是否可以承担iam-role1链接到Cognito 用户池中的cognito-group1Cognito 用户的Cognito 组的 IAM 角色？cognito-user1cognito-user-pool1

我的配置：

Cognito 用户池cognito-user-pool1：

• Cognito 用户cognito-user1属于cognito-group1
• Cognito 组cognito-group1已分配给iam-role1。

Cognito 身份池cognito-identity-pool1：

• 身份验证提供商：cognito-user-pool1
• 已验证角色 =iam-role1

我是：

• IAM 角色iam-role1具有访问 S3 ReadOnly 的策略

此代码允许我向 Cognito 用户池进行身份验证：

AmazonCognitoIdentityProviderClient provider = new AmazonCognitoIdentityProviderClient();
            CognitoUserPool userPool = new CognitoUserPool("user-pool-id", "client-id", provider);
            CognitoUser user = new CognitoUser("cognito-user1", "client-id", userPool, provider);
            InitiateSrpAuthRequest authRequest = new InitiateSrpAuthRequest()
            {
                Password = "cognito-password1"

我正在删除带有数据的表中的一列xxx。DACPAC 正在生成如下检查。

IF EXISTS (select top 1 1 from [dbo].[xxx])
    RAISERROR (N'Rows were detected. The schema update is terminating because data loss might occur.', 16, 127) WITH NOWAIT

所有数据迁移均已在预部署脚本中完成。目前我已经手动注释掉了。

如何防止它自动生成？

更新后Auth0登录样品使用HashLocationStrategy在app.module.ts:

import { LocationStrategy, HashLocationStrategy } from '@angular/common';
// (...)
@NgModule({
  providers: [
    {provide: LocationStrategy, useClass: HashLocationStrategy},
    appRoutingProviders,
    AUTH_PROVIDERS
  ],  
//(...)

Auth0 Lock authenticated事件不再被引发:

import { Injectable } from '@angular/core';
import { tokenNotExpired } from 'angular2-jwt';

// Avoid name not found warnings
declare var Auth0Lock: any;

@Injectable()
export class Auth0Service {

  // Configure Auth0
  lock = new Auth0Lock('I21EAjbbpf...', '....au.auth0.com', {});

  constructor() {
    // Add callback for lock `authenticated` event
    this.lock.on("authenticated", (authResult) => { …

Currently in the service i am calling http.get as follow

getList(): Observable<Customer[]> {
return this.http.get<Customer[]>("api/customers");

}

in component ngOnInit the list of customer is returned:

this.customerService.getList().subscribe(data => (this.customers = data));

It is working fine. Now i want to sorting the list before returning to the component.

any idea of how to return sorted list in the service to compnent?

D3 用于svg在angular2组件中生成 a 。如何从 svg 事件更新属性x和y组件mousemove？

export class AxisComponent implements OnInit {

    y:number;

        var svgWidth=400;
        var svgHeight=400;
        var margin = {top:25, right:25, bottom:50, left:50};
        var width = svgWidth - margin.left - margin.right;
        var height = svgHeight - margin.top - margin.bottom;

        var svg = d3.select('#container').append('svg')
            .attr('width', svgWidth)
            .attr('height',svgHeight)
            .style('border', '2px solid');

        svg.on("mousemove", function(){
            var xy = d3.mouse(this);

            this.x = xy[0]; 
            this.y = xy[0];
        });
}

从mousemove事件访问时出错：
