injectable poisons

tests, you should create your service (new), because my basedataservice is not dependent on the angular di system to generate it.Service = new Basedataservice (config, HTTP); When the sino-list is used as a Sino-base-data-servie subassembly, the service in the parent component is acquired, so the unit test becomes much better after this is written. Dependency Injection method for service dependent on di system It is through the encapsulation of the module, inject basedataservice into the angula

The ANGULAR2 view is dynamic, and without modifying the source data bound to the UI, we can change whether the data is rendered, rendered, or rendered in the form of instructions.(1). The most commonly used directives provided by ANGULAR2 are:1.*ngif= ' expression ', which is loaded or written in the current element by the result of expression operation.　　2.*ngfor= ' expression and declarations ' loop input array that loads the render template as a view based on the data of each member{{Person.n

Dependency Injection (DI) is the core of Angular 2, and before we dive into the workings of DI, we must first understand the concept of Provider.In Angular 2 We use Provider to describe how the dependent objects associated with tokens are created. There are four ways to create dependent objects in Angular 2, respectively: Useclass Usevalue Useexisting Usefactory Useclass @Injectable () Exportclassapiservice{constructor ( publ

, Access address: http://%s:%s", host, Port) }) The results are shown in chrome test. Step two: Define the hero structure (HERO.TS) Export Class Hero { Id:number; name:string; Constructor (_id:number, _name:string) { This.id = _id; THIS.name = _name; } } Step three: Writing Heroic services (hero.service.ts) Import {injectable} from ' @angular/core '; Import {Http} from "@angular/http"; Import

By default, the response body doesn ' t contain all of the data that might is needed in your app. Your server might return some special header which you had to read explicitly. In such case we can use the { observe: ‘response’} configuration of the Angular HttpClient . Let ' s explore.Import {injectable} from ' @angular/core 'rxjs/observable 'httpresponse' @angular/common/http ' ; Export interface Person { name:string;} @

By default, the new Angular Http client (introduced in v4.3.1 ) uses JSON as the data format for communicating with the Backe nd API. However, there might is situations where you could want to use some other format, like for text/plain fetching a CSV file. The Using the property of this responseType can is achieved quite easily.Import {injectable} from ' @angular/core 'rxjs/observable' @angular/common/http '; @Inj
